The Effect of Physical Activity on Alzheimer's Disease
•
6 likes•2,234 views
Regular physical activity provides several benefits, including reduced risk of cardiovascular disease, increased independence, and alleviated depression. Studies have found that physical activity is associated with improved cognition and memory, and may delay the onset of Alzheimer's disease. One study found that those exercising more than three times a week were less likely to develop dementia as they aged. Research is ongoing to determine if becoming more physically active later in life still provides benefits to reducing Alzheimer's risk. Physical activity appears to impact Alzheimer's-related biomarkers like amyloid levels in the brain.

Exercise and Alzheimer's2012
The presentation discussed the connections between exercise and Alzheimer's disease. It began with an overview of Alzheimer's, defining it as a progressive brain disease that destroys memory and cognitive skills. Statistics showed that Alzheimer's prevalence is increasing as the population ages. The presentation then explored how several lifestyle factors like high blood pressure, obesity, and lack of exercise are modifiable risk factors for Alzheimer's. It concluded by reviewing evidence that exercise may delay the onset of Alzheimer's by positively impacting those risk factors and cognitive functioning.
Attention
This document defines attention, concentration, and their importance in sports. It discusses how attention and concentration allow an athlete to focus on relevant cues and actions under their control. The document outlines different types of concentration, principles of attention, factors that influence attention like information processing and memory systems, and how to measure and improve attentional focus through attention control training and the use of associative or dissociative styles. Barriers to concentration like anxiety, mistakes, and negative thoughts are also discussed.
Pre game meal & carbs loading
The document discusses nutrition strategies for athletes before, during, and after intense exercise. It recommends that the pre-competition meal should be high in carbohydrates (150-300g), consumed 3-4 hours before exercise to replenish glycogen stores. During exercise, consuming about 60g of carbohydrates per hour benefits performance for long duration or high intensity exercise by sparing glycogen and stabilizing blood glucose. The strategies aim to provide steady fuel without large insulin responses that could impair performance.
Eysenck type personality test
Originally Eysenck characterized an individual's personality on two scales. Introversion - extraversion and stable - unstable. A person may thus be
Introverted and Stable,
Introverted and Unstable,
Extraverted and Stable or
Extraverted and Unstable.
The scale, stable - unstable, measures an increasing level of neuroticism. Eysenck's term "neuroticism" does not mean that the persons actually have neurosis, only that they are more inclined to get one.
They are continuous scales, so one can of course also score in the middle, for example, only 50% unstable and only 50% introverted. Later in his career he added Psychoticism.
Effect of exercise on CardioVascular System
1. During exercise, the body undergoes adjustments to supply nutrients and oxygen to active tissues and prevent overheating.
2. There are two types of exercise - dynamic exercise involves muscle movement while static exercise does not.
3. Exercise can be aerobic, using oxygen for energy over long periods, or anaerobic, using glycogen without oxygen for short bursts.
4. The cardiovascular system responds to exercise through increased heart rate, cardiac output, and blood flow to muscles to meet energy demands, while blood pressure rises with intense exercise but falls below resting after as metabolites accumulate.
Fatigue management and recovery strategies for athletes
The document discusses fatigue management and recovery strategies for athletes. It defines fatigue and recovery, and outlines various strategies to aid recovery including sleep, nutrition, psychological skills, physical therapy, hydro-recovery, active rest, and tapering training loads. Monitoring tools like daily logs and questionnaires are also presented to track athlete recovery. The goal is to implement recovery-based training to avoid overtraining and enhance performance.
Neuroplasticity
Neuroplasticity refers to the brain's ability to change and adapt throughout life in response to experiences. There are two main types of neuroplasticity - structural, involving physical changes to neurons and synapses, and functional, involving changes in neural pathways and connections that underlie learning and memory. Structural neuroplastic changes include synaptic plasticity, synaptogenesis, neurogenesis, and neural cell death. Functional changes are mediated by synaptic plasticity mechanisms like long-term potentiation and long-term depression. Neuroplasticity allows the brain to form new memories and skills, but can also contribute to cognitive decline or altered motor control depending on the circumstances.
Exercise in Older Adults
1) Middle-aged adults who were least fit at checkups were most likely to develop chronic diseases like heart disease, diabetes, and cancer at an earlier age.
2) While even the most fit adults may still develop chronic diseases, they tended to do so later in life and lived with the diseases for shorter time periods.
3) Long-term marathon running was associated with both benefits and risks for cardiovascular health. It provided a more favorable risk profile but also increased coronary plaque and the risk of cardiac injuries with intense exercise. The risks depended on factors like age, sex, and training status.

Intro to ergogenic aids
The document discusses various performance enhancing substances and methods used by athletes both historically and currently. It describes substances that improve performance like anabolic agents and EPO but also lists serious health side effects. It notes that prior to the 1960s, doping was common due to a lack of testing but that groups like the IOC have since worked to establish banned substance lists and anti-doping initiatives in response to deaths. Both personal and environmental reasons are discussed for why some athletes still resort to illegal performance enhancement despite the health risks and potential penalties.
Cognitive approach & therapies
The cognitive approach views abnormalities as the result of errors in thinking between a stimulus and response. It was influenced by behaviorism and focuses on distortions in thinking processes. Cognitive biases like minimization and cognitive therapies like CBT aim to modify irrational thoughts. Studies show CBT can effectively treat disorders like depression by challenging negative thinking patterns, though it may overlook biological factors and not work for all disorders.
Role And Use Of Sports Psychologists
The document discusses the role and use of sports psychologists. Sports psychology studies how an athlete's mind affects performance and vice versa. Sports psychologists aim to help athletes overcome pressures, improve performance, and increase enjoyment through techniques like mental imagery, goal setting, concentration skills, and relaxation. They teach athletes to focus on the task, center themselves, and use positive self-talk to stay in control and confident. For example, a gymnast struggling with a vault could benefit from imagery, concentration, self-talk, and goal setting taught by a sports psychologist to help her successfully learn the skill.
Sports psychology
This document provides an overview of sports psychology, including:
- A brief history noting its origins in Germany in the 1920s and key early figures.
- An introduction to various topics within sports psychology like exercise psychology, principles of rehabilitation, preparing for competition, and theories.
- A discussion of diagnostic tools and treatment approaches used by sports psychologists, including goal setting, imagery, and cognitive behavioral therapy.
- Examples of evidence from studies on topics like the relationship between psychology and injuries.
Effects on cardiovascular system
Regular exercise has long-term benefits for the cardiovascular system. It decreases resting heart rate and improves heart recovery rate as the heart becomes stronger and more efficient. Additional benefits include increased stroke volume, meaning the heart can pump more blood with each beat, as well as reduced blood pressure. Overall, regular exercise leads to a more efficient cardiovascular system that is under less stress.
Sports psychology
Sports psychology is the study of how psychology influences sports performance. Some sports psychologists work with athletes to improve performance and increase motivation. Key aspects of sports psychology include awareness, focus, concentration, anxiety, confidence, and motivation. Maintaining awareness and using proper concentration techniques can optimize an athlete's performance. Both state and trait anxiety can negatively affect performance if not properly managed. Successful athletes focus on their task in the present moment rather than fearing failure. Motivation influences an athlete's effort, ability to overcome setbacks, and overall competition results.
sps431-t1_an introduction to sport psychology
Sport psychology is the scientific study of the psychological factors that influence and are influenced by participation and performance in sport, exercise, and physical activity. It involves understanding how psychological skills can enhance athletic performance and overall well-being through applying knowledge about the social, cognitive, and affective factors that influence sport performance. The key activities of sport psychologists include consulting, clinical work, research, and teaching. There are also various areas and careers within the field, such as clinical, educational, and social psychology.
Introduction to Physiological Psychology
This document provides an introduction to physiological psychology. It defines physiological psychology as the branch of biological psychology that deals with the workings of the mind and body and how the brain relates to behavior. It explains that physiological psychology studies how bodily functions are directly linked to the brain and how small changes in the brain can affect behavior. The document then discusses some important figures in the history of the field, including Hippocrates' idea that emotions originate in the brain, Galen's theories about brain functions and personalities, Descartes' view of the body as a machine responding to stimuli, and Muller's ideas about nerve fibers relaying messages between the brain and body.
7 ergogenic aids
The document discusses doping in sport and performance enhancing drugs. It provides a timeline of banned substances in sport from ancient Greece to modern times. Key events discussed include the 1988 Olympics where Ben Johnson tested positive for steroids and the establishment of WADA in 1999. Specific performance enhancers like anabolic steroids, human growth hormone, EPO, and THG are defined. The BALCO scandal is summarized where many top athletes were linked to the lab. The document discusses views on whether performance enhancing drugs should be banned and debates around natural advantages in sport.
Pdhpe Sports Psychology
The role of sports psychologists is to prepare athletes mentally for competition in the same way their body is prepared physically. They help athletes deal with stress, pressure, emotions, and set goals. Sports psychologists use mental training techniques like visualization, positive self-talk, relaxation, and anxiety control to improve an athlete's performance and help them overcome competition pressure. Common issues psychologists help with include nerves, lack of discipline, pre-competition anxiety, and depression from feeling they let their team down.

Porges - Polyvagal - Autism - Hakomi Conference Presentation - Brain Behav...
This document summarizes Stephen Porges' Polyvagal Theory, which proposes that the autonomic nervous system evolved in a phylogenetic hierarchy with three circuits that regulate behavioral and physiological responses to the environment. The most recently evolved circuit, involving the myelinated vagus nerve, supports social behaviors and self-soothing functions in safe environments. The two older circuits involve the sympathetic nervous system for mobilization responses, and the unmyelinated vagus for life-threatening situations like death feigning. Porges argues this neurophysiological framework can provide insights into health, learning, and social behavior.
Importance of Exercise with Diabetes
This document discusses the importance of exercise for managing diabetes. It notes that exercise can lower blood sugar, increase insulin sensitivity, reduce medication needs, and even potentially reverse diabetes symptoms. Structured aerobic and resistance exercise just three times per week can lower A1C by an average of 0.67% in three months. The document outlines barriers to exercise and provides seven strategies to overcome them, such as finding enjoyable activities and developing a reasonable exercise plan. It emphasizes setting specific, measurable, attainable, realistic, and time-bound goals to stay motivated.
Exercise for Diabetes by Selim
1) Regular moderate exercise of at least 150 minutes per week can reduce the risk of developing diabetes in people who are predisposed.
2) Exercise improves physical fitness and cardiovascular health as well as glucose control for those with type 1 or type 2 diabetes. It works by increasing insulin sensitivity and glucose transporters.
3) An exercise prescription for diabetics includes 30-60 minutes per day of aerobic activity, moderate weight training 2 times per week, monitoring heart rate and blood glucose levels, and gradual progression of intensity over time.

Assessment In Sports Psychology
The document outlines various assessments used in sports psychology to measure athletes' mental states and performance. It discusses tools to measure attention, attentional style, anxiety, mood, stress, burnout, and imagery training. Tests mentioned include questionnaires like the Profile of Mood States and Maslach Burnout Inventory, as well as techniques like reaction time probes and physiological monitoring to assess concepts like attention, anxiety, and stress. The assessments are designed to help sport psychologists evaluate athletes' mental strengths and weaknesses.
Clinical neuropsychological testing
1. Clinical neuropsychological testing involves assessing intelligence, personality, and neurocognitive abilities through objective and projective tests.
2. Common intelligence tests include the WAIS, which measures verbal and performance skills, and intelligence is quantified as an IQ score.
3. Personality is often assessed through self-report measures like the MMPI or projective tests like the Rorschach inkblots and TAT cards which analyze responses.
4. Neuropsychological tests evaluate specific cognitive domains like memory, attention, language, and visual-spatial skills which can localize brain dysfunction when impaired. Test results must be interpreted carefully and discussed therapeutically with the patient.
Utilization of BioFeedBack In Sports
Biofeedback is gaining popularity in sports psychology for improving athletic performance and facilitating recovery from injury. Several studies show biofeedback reduces anxiety and stress, allowing optimal performance. It improves focus, concentration, and cognitive function following concussions. HRV biofeedback lowers anxiety and improves basketball and golf performance. Neurofeedback activates prefrontal areas associated with confidence. A baseball player increased self-confidence and performance using EEG biofeedback combined with imagery. Future research should establish guidelines and study long-term benefits to validate biofeedback's role in sports.

BENEFITS OF EXERCISE
This document discusses the benefits of exercise and fitness programs. It outlines that regular exercise strengthens the cardiovascular system, improves balance, reduces stress and anxiety by increasing happy chemicals in the brain, improves self-confidence, increases brainpower and memory, strengthens muscles and bones, reduces the risk of heart disease, and prevents obesity. A fitness program incorporates physical activities to target functional, skill-related, and health-related fitness goals.
A healthy brain and taking care of it
1. The document provides 5 tips for keeping your brain healthy as you age: exercise regularly, get plenty of sleep, eat a Mediterranean diet, stay mentally active through activities like puzzles and reading, and reduce stress.
2. It recommends exercising several times a week for 30-60 minutes to increase blood flow to the brain and counter age-related declines.
3. Getting 7-8 hours of consecutive sleep nightly allows the brain to consolidate memories and clear proteins, boosting memory and health.
Fitness and Mental Health
Dale Patterson, Recreational Therapist at The Royal, shares why it's so important to exercise - not just for your body but your mind too.
Poff presantation
A healthy lifestyle combines good nutrition and physical fitness to improve quality of life and decrease health risks. Regular physical activity provides both physical and mental well-being benefits. It helps control weight, builds healthy bones and muscles, and reduces risks for chronic illnesses, premature death, and conditions like heart disease, diabetes, and cancer. Physical activity is important throughout life to support brain growth, development, and cognitive performance from childhood through adulthood.
2015: Memory Changes Across the Spectrum of Brain Aging-Galasko
Memory and cognition change with normal aging in several ways:
- Memory retrieval becomes less efficient although new learning is intact
- Slowing of cognition and motor skills occurs
- Executive function such as multitasking declines slightly
Mild Cognitive Impairment (MCI) involves memory decline with normal other cognition and minimal functional impairment, progressing to dementia in 8-15% per year. Brief cognitive screens plus informant reports can detect MCI and dementia so interventions can maintain function. Lifestyle factors like exercise, cognitive stimulation, and heart health may help preserve brain health in aging.
Cognitive Benefits of Exercise for Adults
Regular physical exercise is associated with cognitive benefits for adults:
1) Aerobic exercise improves attention, processing speed, executive function, and memory in adults. Longer exercise periods are linked to greater gains in attention and processing speed.
2) Moderate aerobic training for 8 weeks significantly improved cognitive processing speed over 100% in young adults with mild to moderate intellectual disabilities.
3) Higher levels of physical activity are associated with larger hippocampal volume, an important brain region for memory and spatial representation, in healthy middle-aged adults.
Cognitive Benefits of Exercise for Seniors
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.

Physical activities and_preservation_of_brain_function
Physical exercise is beneficial for brain health and function. It can help preserve brain function as people age and may reduce the risk of dementia and Alzheimer's disease. Exercising the body also exercises the brain by increasing blood flow and oxygen delivery to the brain. Simple physical activities like walking, as well as mentally stimulating games and puzzles, can help boost brain health at any age.

Pitch_preventie_AD.pptx
Physical exercise can help prevent Alzheimer's disease. Regular moderate physical activity improves cognitive function for all ages and existing prevention programs that focus on physical activity for the elderly have shown positive effects. A proposed prevention program recommends frequent, moderately intense and diverse leisure physical activities that are accessible and have low costs and effort but high impact. Small environmental changes may help promote physical activity for people of all ages as a low-cost, high-benefit approach to reducing Alzheimer's risk.
Ch12 01
Being physically active provides significant mental, physical, and social benefits. It improves overall health by strengthening muscles and bones, boosting energy levels, and reducing the risk of diseases. Regular physical activity is important for teens, who should aim for at least 60 minutes per day. While exercise is purposeful physical activity, any movement that uses energy counts toward daily activity goals. A sedentary lifestyle puts one at higher risk for health issues like obesity, diabetes, and cardiovascular problems.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic.
