Maintaining cognitive vitality remains challenging in our rapidly aging society. It has been well documented that as we age, even simple daily tasks become challenging as it increasingly draws cognitive resources from neural pathways outside of the primary Motor Cortex. The purpose of this statement is to explore the potential use of novel motor training as a countermeasure to alleviate cognitive declines in older adults.

The Brain as a Whole: Executive Neurons and Sustaining Homeostatic GliaInsideScientific
Carl Petersen and Alexei Verkhratsky share their research on homeostatic neuroglia and imaging of neuronal network function. This webinar is brought to you by APS’ new journal, Function, and part of their Physiology in Focus learning series.
During this exclusive live webinar, Carl Petersen and Alexei Verkhratsky discuss astrocyte-mediated homeostatic control of the central nervous system, and how optical and 2-photon microscopy can be used for functional neuroimaging.
Imaging Neuronal Function
Carl Petersen, PhD
Highly dynamic and spatially distributed neuronal circuits in the brain control mammalian behavior. Through technological advances, optical measurements of neuronal function can now be carried out in behaving mice at multiple scales. Wide-field imaging allows the dynamic interactions between different brain areas to be studied as sensory information is processed and transformed into behavioral output. Within a brain region, two-photon microscopy can be used to image the neuronal network activity with cellular resolution allowing different types of projection neurons to be distinguished. Together optical methods provide versatile tools for causal mechanistic understanding of neuronal network function in mice.
Astrocytes: indispensable neuronal supporters in sickness and in health
Alexei Verkhratsky, MD, PhD, DSc
The nervous system is composed of two arms: the executive neurons and the homeostatic neuroglia. The neurons require energy, support, and protection, all of which is provided by the neuroglia. Astrocytes, the principal homeostatic cells of the brain and spinal cord, are tightly integrated into the neural networks and act within the context of the neural tissue. As astrocytes control the homeostasis of the central nervous system at all levels of organization, from the molecular to the whole organ level, we can begin to define and understand brain vulnerabilities to aging and diseases.
STUDY AND IMPLEMENTATION OF ADVANCED NEUROERGONOMIC TECHNIQUES acijjournal
Research in the area of neuroergonomics has blossomed in recent years with the emergence of noninvasive techniques for monitoring human brain function that can be used to study various aspects of human behavior in relation to technology and work, including mental workload, visual attention, working memory, motor control, human-automation interaction, and adaptive automation. Consequently, this interdisciplinary field is concerned with investigations of the neural bases of human perception, cognition, and performance in relation to systems and technologies in the real world -- for example, in
the use of computers and various other machines at home or in the workplace, and in operating vehicles such as aircraft, cars, trains, and ships. We will look at recent trends in functional magnetic resonance imaging (fMRI), with a special focus on the questions that have been addressed. This focus is
particularly important for functional neuroimaging, whose contributions will be measured by the depth of the questions asked. The ever-increasing understanding of the brain and behavior at work in the real world, the development of theoretical underpinnings, and the relentless spread of facilitative technology in the West and abroad are inexorably broadening the substrates for this interdisciplinary area of
research and practice. Neuroergonomics blends neuroscience and ergonomics to the mutual benefit of both fields, and extends the study of brain structure and function beyond the contrived laboratory settings often used in neuropsychological, psychophysical, cognitive science, and other neurosciencerelated fields. Neuroergonomics is providing rich observations of the brain and behavior at work, at home, in
transportation, and in other everyday environments in human operators who see, hear, feel, attend, remember, decide, plan, act, move, or manipulate objects among other people and technology in diverse, real-world settings. The neuroergonomics approach is allowing researchers to ask different questions
and develop new explanatory frameworks about humans at work in the real world and in relation to modern automated systems and machines, drawing from principles of neuropsychology, psychophysics, neurophysiology, and anatomy at neuronal and systems levels. The neuroergonomics approach allows researchers to ask different questions and develop new explanatory frameworks about humans at work in
the real world and in relation to modern automated systems and machines. Better understanding of brain function can, for example, provide important guidelines and constraints for theories of information presentation and task design, optimization of alerting and warning signals, development of neural prostheses, and the design of robots. As an interdisciplinary endeavor, neuroergonomics will continue to
benefit from and grow alongside developments in neuroscience, psychology,
EFFECT OF MIRROR THERAPY ON UPPER EXTREMITY MOTOR FUNCTION IN STROKE PATIENTSismailabinji
EFFECT OF MIRROR THERAPY ON UPPER EXTREMITY MOTOR FUNCTION IN STROKE PATIENTS
Stroke is one of the main causes of disability around the globe. plegia (complete paralysis) or paresis (partial weakness ) are common following a stroke. According to the Journal of Physical Therapy Science, about 85 percent of stroke survivors will suffer from hemiplegia, and at least 69 percent will experience a loss of motor function in the upper limb.
Although these changes may not be permanent, some people regain partial or full limb function, the road to recovery can be long. But did you know that it is possible to trick the brain into believing what it sees? Mirror therapy is being used more and more in stroke rehabilitation to dupe the brain and restore limb function.
STROKE: is defined as the rapidly developed clinical signs of global or focal disturbance of cerebral function, lasting more than 24 hours or leading to death, with no apparent cause other than of vascular origin. (WHO, 2017)
MOTOR FUNCTION motor function is the ability to learn or to demonstrate the skillful and efficient assumption, maintenance, modification, and control of voluntary postures and movement patterns.
In mirror therapy, a mirror is placed beside the unaffected limb, blocking the view of the affected limb. This creates the illusion that both limbs are functioning properly.
Mirror theory is based on evidence that action observation activates the same motor areas of the brain as action execution. Observed actions lead to the generation of intended actions, engaging motor planning and execution.
Mirror neurons are type of brain cell that respond equally when we perform an action and when we witness someone else perform the same action. They were first discovered in the early 1990s, when a team of Italian researchers found individual neurons in the brains of macaque monkeys that fired both when the monkeys grabbed an object and also when the monkeys watched another primate grab the same object.

The brain is the most active organ in the body and therefore very sensitive to daily stresses. Getting the right amount of exercise, proper nutrition, cognitive stimulation and adequate sleep enhances brain structure and function throughout our lives.
Great minds over the ages have known that physical activity is necessary to keep the mind strong and clear. Aerobic exercise improves cognitive function in humans, produces increases in brain volume, stimulates neurogenesis and synaptogenesis, and increases neurotrophic factors in different areas of the brain. Physical exercise may protect the brain against reduction in cognitive functions in the elderly and delay the onset and slow down the progression of Alzheimer disease.
The loss of strength, cognitive function and stamina attributed to aging is in part caused by reduced physical activity. Inactivity increases with age. By age 75, about 1 in 3 men and 1 in 2 women engage in no physical activity. Among adults aged 65 years and older, walking and gardening or yard work are, by far, the most popular physical activities. Social support from family and friends has been consistently and positively related to regular physical activity.
Older adults should consult with a physician before beginning a new physical activity program. Physical activity need not be strenuous to achieve health benefits. Older adults can obtain significant health benefits with a moderate amount of physical activity, preferably daily. A moderate amount of activity can be obtained in longer sessions of moderately intense activities (such as walking) or in shorter sessions of more vigorous activities (such as fast walking or stair climbing). Additional health benefits can be gained through greater amounts of physical activity, by increasing the duration, intensity, or frequency. Because risk of injury increases at high levels of physical activity, care should be taken not to engage in excessive amounts of activity. Previously sedentary older adults who begin physical activity programs should start with short intervals of moderate physical activity (5-10 minutes) and gradually build up to the desired amount. In addition to aerobic activity, older adults can benefit from muscle-strengthening activities. Stronger muscles help reduce the risk of falling and improve the ability to perform the routine tasks of daily life.
This presentation provides a current summary of the human research on aerobic activity and cognitive function in seniors.

Cognitive Benefits of Exercise for Children and TeensMark Dreher PhD
The brain evolves during our childhood years as it continues to develop and is affected by lifestyle habits such as physical activity, cognitive activity, nutrition and sleep.
Although there is growing scientific evidence that exercise is associated with improved cognitive function, academic performance, and overall health in children, the limited amount of time generally dedicated to physical activity during the school day continues to decline in many schools.
The activity requirements for healthy brain and cognitive function are really relatively modest. For children, moderate aerobic activity of about 60 minutes a day can make a big difference, especially in children that are currently low-performers. There is work to be done in the United States and other countries to meet these activity goals as only about 30% of high school students achieve them.
This presentation provides a current summary of the human research on aerobic exercise and cognitive function in children and teens.

Effects of Internet Based Training on Cognition in Older Adults
Specific Aims
The idea that maintaining high levels of cognitive activity protects the brain from neurodegeneration is not new, and much evidence has accumulated that people with high levels of cognitive ability and activity tend to maintain cognitive function well as they age (Hertzog et al. 2009). Beyond the idea of maintaining cognitive function in healthy aging, studies such as Verghese et al. (2003) found that higher levels of cognitive activity were associated with lower rates of dementia in a 21- year longitudinal study. While much of the data indicating higher levels of cognitive activity leads to better long-term function is necessarily correlational, a number of studies have begun to systematically assess the effect of cognitive interventions on cognitive function. The largest of these, the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE; Jobe et al. 2001) has found long lasting effects (5 years; Willis et al. 2006) of relatively short cognitive training activities (10 hours).
The specific aim of this proposal is to assess the effectiveness of A Fictitious Brain Training Program on research participants followed longitudinally who may be experiencing the very earliest signs of cognitive decline. Recent research tracking the trajectory of age related cognitive decline (e.g., Mungas et al. 2010) has suggested that it may be possible to identify cognitively healthy individuals at risk for significant imminent cognitive decline by examining baseline cognitive assessments or recent change, even though test scores do not reach the abnormal range.
Background
Techniques for maintaining and enhancing cognitive function in an increasingly aging population are of great potential benefit to those who might suffer from Alzheimer’s disease and related disorders and also to society as a whole. Higher cognitive function leads to better maintenance of activities of daily life, less need for chronic care, and direct improvements in quality of life. Research examining effective methods for cognitive enhancement is becoming increasingly prevalent and has led to a number of recent review studies, e.g., Hertzog et al. (2009), Lustig et al. (2009), Green & Bavalier (2008). These studies review evidence from both longitudinal studies of increased levels of mental activity on maintenance of cognitive function and intervention studies aimed at directly improving cognition with targeted cognitive training. For these cognitive interventions to provide widespread benefit, it is critical ...

Summary
Pilates exercise is popular in the general population [1] the clinical and fitness areas (Segal, 2004). The use of the Pilates at least at the end of
training to improve dancers flexibility and trunk mobility was suggested [2]. Flexibility and joints mobility as well as core strengthening is the focal
point of the Pilates exercises [3]. Hamstrimg muscle elasticity is important in many functional and athletic activities, because dancers must show high
amplitude movements with lower extremities and trunk [3]. Aerobic Gymnastics athletes continuously perform complex movements following music
patterns, which require high levels of fitness, strength, flexibility and range of motion in joins [4]. In spite of a growth in gymnastic modalities, we didn’t
find research about Pilates effect to young age Aerobic Gymnastics athletes. The aim of this study was to evaluate changes in Aerobic Gymnastics athletes
hamstrings muscles elasticity and trunk mobility after 7 and 14 weeks of Pilates exercises.
Abstract
The goal of any practice or physical education class is typically to enhance and optimize performance in the skills of interest. However, it is sometimes
difficult for students to have a sound understanding of the movement tasks and how to alter their performance based on verbal feedback alone. With
access to portable electronic devices growing rapidly, it is not uncommon for most people to have a cell phone or tablet readily available. Instead of
banishing these devices from the facility, there may be an opportunity to use these devices to better convey points of interest from the instructor to the
student. A single Physical Education class was used to trial the use of video feedback combined with the traditional verbal feedback following a forward
roll sequence for grade. After reviewing the video footage and receiving verbal feedback from their instructor, students not only improved their scores
but also gained confidence in their abilities. The use of personal electronic devices can allow students to see what the instructor sees in order to optimize
their performance. By allowing such devices in the classroom (whether it’s the instructor’s or students’) for instructional purposes only, students can
begin to identify and correct any flaws to their routine or movement skills as early as possible.
Introduction
There is no uniform conception in the literature about what an emotion is and consists of [1,2]. Consensually, essential aspects have been considered to understand emotion: the presence in emotions of physiological changes, the mobilisation of bodily actions or “tendencies of action” and the subjective experience that involves; and emotion has been approached as a result of a system of analysis and processing of information. But taking each of the elements indicated separately has not favoured knowledge of emotion being presented in an integrated manner [3]. Moreover, the investigators have been supported in their work by different a theoretical orientation, which makes it even more difficult to integrate all the knowledge. One perspective that tackles this question is the theories of Embodiment, which have their origin in the French philosopher Merleau-Ponty (1908-1961), according to which psychological processes are based on bodily states. From the perspective of Embodiment, perceiving, recognizing and interpreting an emotion in ourselves or in others requires information from bodily systems. In this way “experiencing emotional states affects somatovisceral and motoric systems” and vice versa. In other words, “bodily states have effects on how emotional information is processed” [4].
Abstract
The aim of this article is to know at which level a club is more efficient and how promotion and relegation affects technical efficiency. The sample consists of clubs that played at least one season in the First Division in Spanish Professional Football League between seven seasons. The method for calculating technical efficiency is Data Envelopment Analysis and this is combined with the study of trend and stability to ensure the correct choice of model and to check the robustness of the results. Our conclusion is that teams that have promoted and relegated are more efficient. These clubs improve their technical efficiency after being relegated and staying in the lower category. It is necessary to pursue its optimal positioning depending on its sporting potential and its economic financial capacity but not necessarily the promotion. We suggest that the Spanish Football League review the conditions and format to promotion.
Abstract
During the lifespan, there are multiple factors influence the longevity including genotype, metabolism, physiology, sociodemographic and environmental factors, nutritional and lifestyle habits. Nutrition during the life time has an effect on the health status. Dietary indexes, certain dietary patterns and dietary guidelines have been used for analysing dietary pattern and life expectancy relationship in many studies. Dietary pattern has an important effect on longevity. The cohort study results indicate that diet quality and Medittarenean diet have potential effects on longevity. The important effects of nutrition on longevity related with quality, quantity, frequency, variety and emotional satisfaction. Therefore, nutritional strategies that provide clear benefits for ageing linked with both physiological and psychological functions to maintain life quality. The aspiration is not only to “live longer” but to “live better,” and to maintain optimal qual¬ity of life during the later stages of life.
Abstract
Purpose: The purpose of this pilot study was to develop test methodology that would allow for an estimation of the relative contributions of buoyancy and hydrodynamics on swim performance.
Methods: One trained swimmer completed three familiarization trials followed by eighteen randomized swim sessions where each condition no wetsuit (NS), low buoyancy wetsuit (LBW), high buoyancy wetsuit (HBW), NS plus pull buoy (NSB), and HBW matched to buoy buoyancy (HBW+) were tested four times each. Buoyancy for all conditions was measured via hydrostatic weighing system. All data are presented as means+SD and change scores (95% CI).
Results: Coefficients of variations with each condition were about 2%. DB decreased by 2.29% for LBW, 2.80% for HBW, 1.93% for NSB, and 1.96% for HBW+, which resulted in an increase in buoyancy lift force. LBW and HBW improved 800-yd swim times over NS -70.6 (-86.2, -55.0) sec, and -69.1 (-84.0, -54.3) sec, respectively. Swim times for 100-yd were also similar between LBW, -9.4 (-10.7, -8.1) sec, and HBW, -7.9 (-11.4, -4.5) sec. Neither stroke rate nor total strokes differed between LBW and HBW, though both appeared significantly lower than NS. In HBW+ trials, the difference in 800- yd and 100-yd times between NSB and NS was -25.2 (-60.3, 10.0) and -1.7 (-19.6, -16.3), respectively, while HBW+ vs NSB 800-yd and 100-yd time differences were -26.6 (-28.3, -24.9) and -5.7 (18.9, 7.5).
Conclusion: The outlined protocol can produce reliable results. These data support earlier assertions that buoyancy may reach a point of diminishing returns, and also indicate that wetsuit hydrodynamics play larger role in swim performance as velocity increases. The protocol outlined could aid in optimal wetsuit design without the need for advanced testing equipment.
Abstract
The present investigation has been conducted to find out the relationship of selected motor fitness tests to percentage of body fat and reaction time (visual) in mid level male footballer players volunteered to participate in this study.16 students of 15 to 18 years of age and having training in BKSP, were recruited as the subjects. The data on the variables such as percentage of body-fat (BF), speed, agility and reaction-time (RT) were collected by using standard tools and techniques. Each subject’s speed, agility, and reaction time were measured, and the data analyzed using Pearson’s correlation and paired t tests (using SPSS-16). There were no meaningful correlations between reaction time and speed in the subjects .There was a negative correlation between percentage of body fat and reaction time.

The motivation and habits of rock climbers were investigated using mixed methodology in order to better understand exercise participation. Forty-one patrons of a south eastern United States climbing gym completed a demographics form and adapted Sports Motivation Scale II (SMS-II), while thirty-six participants completed the Rock Climbing Motivation Survey (RCMS). Those with higher climbing frequency reported significantly higher levels of identified regulation than individuals who climbed less often (p=0.011). According to a thematic analysis, exercise balance and personal growth and challenges were the most commonly reported themes of motivation for rock climbing. The most frequently cited barriers were injury and time. Participants reported external motivators to climb upon initiation of the sport, but appeared to rely more on internal motivators to continue climbing. These findings, which are supported by current literature on physical activity, may be applicable to promoting exercise participation and maintenance.
Introduction: Partial or complete aplasia of the posterior arches of the atlas is a well-documented anomaly but a relatively rare condition caused by a defect in their closure. This condition is usually asymptomatic so most are diagnosed incidentally.
Case report: We report the case of a patient who presents a defect of the posterior arch of atlas.
Conclusion: There is a variety of the congenital defects of the arch of the atlas. Further studies are required on these lesions in order to take possible protection measures against trauma, and the selection between conservative or surgical treatment.
Abstract
The rehabilitation counsellor works with people with disabilities to assist them in ways to improve their quality of life and vocational outcomes. The types of disabilities among people are diverse, multifaceted, and vary in severity. One such disability group is individuals with cancer. Persons with cancer account for a minimal percentage of the total successfully closed vocational rehabilitation cases. Over the past few decades, the prognosis of many types of cancer has improved, with a resulting increase in the number of cancer survivors who have the ability to resume work after treatment and therapy. This article provides a comprehensive review of rehabilitation counsellors’ involvement in enhancing the lives of individuals with cancer including the employment means, Psychological Impact, and effective interventions to employ these goals.
Abstract
The aim of this study was to examine and compare the acute effects of basketball-specific fatigue on muscular stiffness and reactive strength in male adolescent basketball players of two age categories. Reactive strength, expressed by means of the reactive strength index (RSI), and leg stiffness (LS) as mechanisms associated with the risk of ACL injury were measured in eleven players of the U16 category (age 16.1±0.4 years; body height 185±6.5cm; body mass 74.3±9.9kg) and ten players of the U18 category (age 17.7±0.4 years; body height 187±5.7cm; body mass 79.7±7.4kg) pre and post simulated basketball match play (SBFP28). RSI was determined by a drop jump test, LS by a 20 sub-maximal two-legged hopping test. No significant effects of SBFP28 on the monitored parameters were observed with the exception of RSI in U16 (p=0.013, r=0.53). Similarly, there were no significant differences in the fatigue-related responses to SBFP28 for RSI and LS between the age groups. These results indicated that irrespective of age, the stabilization function of the knee muscles was not impaired and consequently the risk of ACL injury was not increased.
Abstract
Background: Physiotherapy is multi-dimensional and can treat a vast variety of conditions, ranging from musculoskeletal aches, arthritis, joints problems, paraplegia, hemiplegic, sports injuries and frozen shoulder etc. Apart from culture competency and core medical knowledge a physiotherapist must be competent enough in all physiotherapist medical conditions where physical therapy plays a vital role. This study aims to identify the frequency of common clinical conditions among client presented at Habib Physiotherapy Complex (HPC), Hayatabad during 2010.
Methodology: This was a descriptive study; the data were retrieved from record register of HPC (Indoor and Outdoor patients) recording their presenting complaints and known diagnoses. Data was collected on a structure grid. Data was analyzed using SPSS version 15 and presented in term of frequency and percentages.
Result: The majority of clients (1280 (29%)) were suffering from low back pain. The second common condition 891(20%) was osteoarthritis of the knee joint and cerebrovascular accidents 824(18.4%), while cervical pain accounted for 734(16.4%). The rest of clinical conditions included; frozen shoulder, pelvic inflammation, cerebral palsy, polio effected and paraplegia.
Conclusion: The Study reveals the occurrence of Osteoarthritis (Low Back, Cervical Pain, and Knee Joints Pain) were the most common condition which deteriorated the performance of common individuals in our society.
Abstract
Brain-derived neurotrophic factor (BDNF), a dimeric protein found throughout the brain, promotes the survival of nerve cells by playing a role in the growth, maturation, and maintenance of cells [1]. Along with supporting the survival of existing neurons, BDNF encourages differentiation and growth of new neurons and synapses [2,3]. In the brain the hippocampus, cortex, and basal forebrain, which are vital to learning, memory, and higher thinking, are all locations where BDNF is active [4]. A number of stimuli have been found to increase BDNF gene regulation including light in the visual cortex, osmotic in the hypothalamus, electrical in the hippocampus, and exercise in the hippocampus [5].
Introduction
Achilles Tendon, the largest and strongest tendon in the human body is formed by fusion of the tendinous portion of calf muscles; the gastrocnemius and soleus [1,2]. Achilles tendon can largely with stand tensional forces of locomotion. The incidence of Achilles tendon injuries has increased considerably during the pastdecade [1-5]. Such injuries account for 45% of all sports related injuries among athletes and general public. Achilles tendon complaints generally represent most tendon problems in any population and can be divided into “Spontaneous ruptures” (excessive loadinginduced injury/degeneration of tendon without any predisposing systemic diseases); and “Overuse injuries” (traced to sports and exercise-related overuse). Sometimes, a systemic disease, such as rheumatoid arthritis may manifest with Achilles tendon symptoms, but this represents only a minority (~2%) of all cases [1,6].
Abstract
Physical inactivity challenge has been addressed from different approaches in recent years due to the negative effects of its consequences at public health level. However, the number of people who do not perform sufficient physical activity on a daily basis is not decreasing. Surprisingly, it is not common to involve the fitness & wellness industry in interventions to address inactivity in leisure time despite the industry aim to promote a healthy lifestyle through physical exercise and its resources. Whilst the industry seems not to be interested in collaborating with public bodies and research centres. In this manuscript, we discuss the reasons why this industry should get involved in the effort for addressing physical inactivity using community-based intervention
Abstract
Frequent Knee Locking is an incapacitating condition that requires a thorough clinical, radiological and arthroscopic evaluation. The common causes are meniscal injury followed by torn anterior cruciate ligament and osteochondral loose bodies in the joint space. Our case describes an unusual case of frequent left knee locking. After clinical and radiological examinations the provisional diagnoses of medial meniscus tear was done. A diagnostic arthroscopy of the left knee revealed normal meniscus, cruciates and a medial patello femoral plica slipping into the patellofemoral joint causing the locking sensation. The plica was resected. At 6 month follow up there is no recurrence of symptoms.
Abstract
Healthy lifestyle can be defined as controlling all behaviours affecting the health of the individual, managing daily activities to improve health and reducing disease risks. Lifestyle behaviours affect disease risk and life quality. The development of healthy lifestyle behaviours, especially nutrition and Physical Activity is associated with type 2 diabetes, cardio-metabolic diseases and cancer risks. World Health Organization defines life quality as “individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns”. Therefore, healthy lifestyle behaviours, especially nutrition and physical activity are related to life quality. Measuring the risk of chronic disease associated with diet quality, healthy lifestyle and life quality is very important in terms of improving public health [1-3].
Abstract
Reductions in O2 delivery (blood flow x O2 content) to contracting skeletal muscle can have adverse effects on physical performance. In this regard, factors that reduce blood flow can promote fatigue by reducing muscle force and/or attenuating the removal of metabolic by products of contraction [1]. Conversely, interventions that enhance O2 delivery at a given work intensity could potentially reduce muscle fatigue or delay its onset, leading to improved Physical Performance. Thus, identification and investigation of such interventions represents an important focus of research in sports science. One possible approach involves the study of dietary factors that may act as ergogenic aids via their actions on cardiovascular function. For example, acute supplementation with beet root juice, which is high in nitrates, has been shown to enhance cardiac output and oxygen utilization and reduce vascular resistance and blood pressure at a given sub-maximal work intensity [2,3]. These effects are indicative of increased O2 delivery to skeletal muscle.
Abstract
Sport behaviour in any situation is culturally defined. The anthropological study of sports can provide a viewpoint of human culture in real sense of the word. Sports as a recreational aspect of culture hold a variety of different meanings across culture. It has been observed that, sports have emerged as a primary area of controversy about men’s and women’s roles. It has also widely argued that women’s sport has changed a little in the present century. Anthropologists considered this issue that sports are the areas where gender inequalities are strongly evident. The present study is the preliminary observations on the relationship between sports and gender along with how the participation in sports can be invigorating and personally empowering experience for women. It finally throws light on how sports are one of the most important issues in gender inequality
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Aging vs Brain Plasticity
On average, humans will develop and retain a steady number
of neural connections throughout lifespan. However, as we age
our overall number of neurons decreases; therefore, requiring
us to share aever-declining resource of neural connections [1].
It has been observed that these connections tend to realign or
redistribute as a means of both normal aging and brain pathology.
This rewiring of new neural pathway’s functions to provide
for new learning of common activities of daily living and other
important communication and motor skills, and has been observed
via positron emission tomography (PET) scans in acute practice
of verbal and motor tasks in normal adult brains [2]. In normal
adults, excitation in brain regions for new learning is observed in a
secondary network consisting of the prefrontal cortex and anterior
cingulate cortex as well as other areas specific to the task. This
secondary network of neural connections is dubbed the scaffolding
areas and is important for the learning of a new motor skill for all
ages.
Contemporary View of Compensatory Mechanisms in
Cognitive Aging
The Scaffolding Theory of Aging and Cognition (STAC) states
that as a compensatory mechanism neural excitability, seen as new
brain circuit pathways in the areas outside of the primary network,
will act to compensate the decrease in available neurons. This
may be due to a decrease in total brain volume, specifically white
matter, overall structural integrity as a function of age or pathology,
or decreased number of dopaminergic pathways [3]. STAC suggests
neural pathway activation changes may be permanent changes that
are a result of overused or underused areas of the brain, but the
scaffolding areas of the brain could be trained or reprogrammed
to be more efficient. Interventional training may help transfer the
execution of simple skills back to the default primary networks, or
optimize the scaffolding areas of the brain to function as proficiently
as the default. Upon revisiting their theory five years later, Park
and colleagues added the inclusion of “life-course factors” such
as experience, genetics and environmental influence that may be
variables that affect the early onset of the use scaffolding areas to
complete simple skills [4].
Although it is recognized that compensatory neural networks
assist with the computations performed by the primary or default
network,therequireduseofcompensatorynetworksinolderadults
has been observed to be less efficient than primary networks used
by young adults that do the same task. A few relevant questions
remain unanswered concerning this topic-What exactly causes
these neural adaptations? Are they entirely detrimental? And what
can be done to prevent any cognitive decline that may be associated
with these age-related adaptations? Currently, researchers aim to
detect if starting interventions at middle age or later adulthood
are beneficial to optimize the scaffolding effect on the secondary
networks to make them more efficient.

Abstract
Maintaining cognitive vitality remains challenging in our rapidly aging society. It has been well documented that as we age, even simple daily
tasks become challenging as it increasingly draws cognitive resources from neural pathways outside of the primary motor cortex. The purpose of
this statement is to explore the potential use of novel motor training as a countermeasure to alleviate cognitive declines in older adults.

over a 5-year period [7]. The reduction in white matter integrity
has been linked to cognitive instability and motor deficits [8]. The
performance of motor coordination has shown to require a higher
cognitive demand in older adults where neural excitability has
been observed to operate in both hemispheres of the motor cortex
[9], and better performance of physical tasks has been linked to
excitation within the primary hemisphere for a unilateral task
compared to those observed to involve both hemispheres [10].
Novel Gross Motor Training May Enhance Brian Health
in Older Adults
Previous studies have measured cognitive and motor function
for simple ipsilateral tasks and found that younger subjects
outperformed the older subjects by expressing more motor
coordination stability, while concurrently activating less brain
regions than the older subjects [11]. Interestingly, Berryman et al.
[5] observed that in some cases, gross movement motor training
yields similar beneficial effects on executive function as aerobic
training would confer. To date, very few investigations examined
if complex gross motor tasks would promote and enhance
performance in cognitive functions in older adults.
Tsengetal.[6]studiedagroupofolderadultsaged50-70(N=36)
undergoing an 8-week intervention consisted of Bilateral Object
Manipulation training (BOM) of 3-ball juggling and conventional
exercise training [12]. Physical function was evaluated by Range-
of-Motion (ROM), Simple and Choice Reaction Times (SRT & CRT),
functional reach, and Gait Velocity (GV). Tseng et al. [6] revealed
that 8 weeks of BOM training may promote better excitability,
reacting time, mobility, and dynamic balance in older adults. Their
finding shed light on the clinical implication of a potentially cost-
effective home-based therapeutic intervention in preserving daily-
living function in older adults. Of note, it appears to be critical that
when learning new motor skills to incorporate non-dominant hand
[13], and tasks that incorporates multi-limb coordination may offer
augmented benefits for older adults [14].
Promoting physical and cognitive health and maintaining
functional capacity of daily activities is imperative in our aging
society. Future research should 1) Aim to validate the physiologic
mechanisms involved in the training adaptations observed in the
current research, 2) Confirm the efficacy of novel motor learning in
preserving cognitive function in older adults, and finally 3) Explore
the potential therapeutic intervention using the BOM model in
clinical population such as mild cognitive impairment and early
stage dementia.
