This study analyzed muscle activation patterns using electromyography (EMG) during four variations of the pull-up exercise: traditional pull-up, suspension pull-up, kipping pull-up, and towel pull-up. The results showed that: 1) The kipping pull-up produced significantly lower EMG activity than the other variations for the latissimus dorsi, mid-trapezius, and biceps brachii muscles. 2) No other significant differences in muscle activation were seen between the traditional, suspension, and towel pull-up variations. 3) The kipping pull-up is the easiest variation on the back muscles out of the four exercises tested.

Emg pilates
The document examines back muscle activity during three traditional mat Pilates exercises - swimming, single leg kick with static prone back extension, and double leg kick - through surface electromyography of healthy adult females. The study found that swimming increased lumbar extensor muscle activity the most at 29% on average compared to the other two exercises. Double leg kicking produced significantly more back muscle activation than single leg kicking. Overall, back muscle activation during the exercises ranged from 15-61% of participants' maximum voluntary isometric contraction levels.
EMG of the Transverse Abdominus and Multifidus During Pilates Exercises
This study evaluated the intensity of muscle activation in the transverse abdominis and multifidus muscles during four Pilates exercises using electromyography. Eight healthy women performed exercises including shoulder bridges, leg circles, and scissors. The results found that shoulder bridges and variations extending the right or left leg produced greater co-activation of the transverse abdominis and multifidus muscles compared to other exercises. Therefore, these exercises are most effective for rehabilitating lumbar spine stability through activation of the core muscles.
ActivMotion Bar Study
As expected when the ActivMotion Bar was compared to medicine balls and standard bars in the same movements there was consistently much higher muscle activation all over the body!
Running Injuries Explained | Free-Running Shoes | Barefoot Shoes
This study examined the relationship between lower leg muscle fatigue and changes in foot pronation in recreational runners. Three recreational runners had their foot biomechanics measured before and after a calf raise fatigue protocol using markers and video analysis. The results found minimal changes between the pre-and post-fatigue foot biomechanics, with coordinate location differences averaging around 1-2 mm. The fatigue protocol may not have been effective at inducing significant muscle fatigue, and the video measurement method lacked accuracy to detect small changes in pronation. More advanced equipment and protocols are needed to further study this relationship.
Choice Lab Presentation (final)
This presentation summarizes research on the relationships between forearm girth, grip strength, thigh girth, and vertical jump height. Six subjects were measured for height, weight, forearm girth, grip strength, thigh girth, and vertical jump. Strong positive correlations were found between forearm girth and grip strength. However, a negative correlation was found between thigh girth and vertical jump height, contrary to the initial hypothesis. The results provide insights for athletes and clinicians on how to assess muscular strength and power.

Rehabilitation of rectus femoris injuries. Experience at Barcelona FC
This document outlines a rehabilitation plan for a 20-year-old soccer player who suffered a complete tear of the rectus femoris muscle in his left leg. The plan is divided into acute, subacute, advanced, and final phases. The acute phase focuses on rest, ice, compression, and bandaging. The subacute phase incorporates quadriceps activation, stretching, massage, and low-impact aerobic exercise. The advanced phase adds strength training and proprioception exercises. Manual therapy continues throughout. Criteria for progression include pain levels and ability to perform exercises with greater range of motion, intensity and velocity. The final phase includes an activation routine before returning to training.
Rehab for Runners (Bodhizone)
Recreational running has increased in popularity since the 1970s. Injury rates among recreational runners are high, between 18-92%, with most injuries occurring in the knee. When rehabilitating injured runners, the GEEP method should be followed: gait analysis and retraining, education, exercise program, and addressing psychosocial components. Common injuries include patellofemoral pain syndrome, IT band syndrome, and patellar tendinopathy. Risk factors for injuries include age, training factors like weekly mileage and cadence, lifestyle factors, and a history of previous injuries. Rehabilitation should focus on correcting gait mechanics like foot strike pattern and step length, strengthening the hips and core, and addressing runners' mindsets around

Emg glúteo medio
1) The study examined electromyographic (EMG) activity in the anterior, middle, and posterior subdivisions of gluteus medius (GM) muscle during three weight-bearing exercises: wall squat, pelvic drop, and wall press.
2) The results showed significant differences in activation levels between the three GM subdivisions and between the three exercises.
3) The wall press produced the highest activation overall and was most effective at activating the posterior GM subdivision, which typically displays higher activation than the other two subdivisions.

This study aimed to determine which exercises best activate the gluteus medius and superior portion of the gluteus maximus muscles while minimizing activation of the tensor fascia lata muscle. Researchers used fine-wire electromyography to measure muscle activity in the gluteus medius, gluteus maximus, and tensor fascia lata muscles during 11 different exercises in 20 healthy subjects. They found that the clam exercise, sidestepping, unilateral bridging, and quadruped hip extension activated the gluteal muscles significantly more than the tensor fascia lata muscle.

The study investigated whether high-intensity (HI) strength training increased pain after total knee replacement (TKR) compared to low-intensity (LI) training. It found that the HI group experienced no more pain or stiffness than the LI group. Both groups improved significantly from baseline on all outcomes measured. The HI exercises were well tolerated, with no patients withdrawing. The study concluded that progressive, submaximal exercise after TKR is safe and tolerated by patients, and more intense interventions should be considered to potentially provide better long-term benefits.

Changes in Body Position during a 2-Minute Push-Up Test by Jennifer K Hewit*, Daniel A Jaffe and Alex J Bedard
In Research & Investigations in Sports Medicine: Crimson Publishers_ Journal of Sports Medicine
Push-ups are a common exercise for individuals of all ages and abilities. Ensuring that the body maintains optimal positioning is crucial throughout any activity. This brief study investigates the changes in hand height and torso angle throughout a 2-minute push-up test. A total of 26 males (23.3±6.9 years old) participated in this study. Video was collected of the entire 2-minute push-up bout. Of interest to the researchers was the distance the hand was in relation to the shoulder and the angle of the torso to the horizontal (both measure from participants' sagittal view). Three consecutive repetitions at the start and end of the bout were used for comparative analysis. Both hand placement in relation to the shoulder and torso angle decreased significantly (p=0.00) from the start of the bout to the end. These results indicate that as participants became tired, they assumed a body position that likely allowed for a greater portion of their body weight to be supported by their lower body. While this adjustment allowed them to continue the exercise, compensational patterns like this should be identified and addressed in training in order to strengthen the primary muscles targeted by the exercise.

The document introduces the Selective Functional Movement Assessment (SFMA) which evaluates movement patterns and asymmetries to identify dysfunctional movement. The SFMA grades movements as functional-nonpainful, functional-painful, dysfunctional-nonpainful, or dysfunctional-painful to guide treatment. Top-tier assessments are demonstrated involving various ranges of motion. Treatment focuses on dysfunctional-nonpainful patterns using corrective exercises to improve motor control and symmetry before mobility or flexibility limitations.

Hamstrings are most susceptible to injury during the late stance phase of sprinting
Clare Poster MWACSM 10.25.15
Eighteen female Division 1 athletes were randomized into either a static stretching (SS) group or control group. The SS group performed stretches of the hamstrings, glutes, and quads for 30 seconds each, while the control rested. Both groups then performed the back squat exercise over 4 sets at 80% of their 1RM, with rest between sets. The SS group showed increased flexibility but no differences in volume lifted, repetitions, or fatigue index compared to controls. The study concludes that SS does not significantly impact multiple set back squat performance in trained females despite gains in flexibility.
Quadriceps Muscle Injuries: James Moore
This document discusses the rehabilitation process for quadriceps muscle injuries from initial injury through return to play. It begins by covering injury classification and the muscle architecture of the quadriceps. It then discusses muscle mechanics in running and kicking sports. Rehabilitation stages are outlined from early isometric exercises to advanced functional training mimicking sports movements. A case study is presented of an athlete who suffered multiple quadriceps injuries and underwent a rehabilitation process focused on hypertrophy, tendon elasticity and returning to high intensity running.

The document discusses hamstring injuries in athletes. It notes that hamstring injuries are among the most common and severe muscle injuries in sports. They often result in long recovery times and have a high risk of reinjury. The document then outlines approaches to treating hamstring injuries, including following classical rehabilitation approaches and applying the limited existing evidence. It also discusses developing injury prevention programs to prepare athletes' muscles for the stresses of their sport. Finally, it presents two case studies of hamstring injuries in athletes as examples of special cases.
Da silva et al. 2008 leg press
This study analyzed muscle activation in the legs during different variations of the leg press exercise performed at submaximum effort levels. Fourteen women performed three types of leg presses - 45° leg press, high leg press, and low leg press - at 40% and 80% of their maximum weight capacity. Electromyography was used to measure activation of the rectus femoris, vastus lateralis, biceps femoris, gastrocnemius, and gluteus maximus muscles. The results showed that mechanical changes from the different exercises affected muscle activation levels in a load-dependent manner. At moderate effort levels, the rectus femoris and gastrocnemius muscles showed greater activation during the 45° leg press and low

Comparative Analysis of Hip Muscle Activation During Common Closed-Chain Reha...Christopher Connelly, CSCS, EP-C
This study investigated hip muscle activation during common closed-chain rehabilitation exercises and running in runners. Electromyography was used to measure gluteus maximus and medius activation during a resisted hip external rotation exercise, single leg squat with trunk rotation, forward lunge with resisted abduction, and running. The forward lunge elicited the highest hip muscle activation, but activation was still substantially less than during running. While the exercises activated the hip muscles more than non-weight bearing exercises, there remains a disconnect between activation during exercises and running. Further research is needed to identify exercises that more closely mimic muscle demands during running.Mi gliaccio et al. 2018 leg press vs. smith
This study aimed to compare quadriceps muscle activation and perceived exertion during the leg press and Smith machine squat exercises. The researchers measured muscle activation via EMG and perceived exertion ratings in athletes performing each exercise across a range of loads. They developed predictive equations to determine equivalent loads between exercises that produce the same muscle activation and perceived exertion. The muscle activation equation was less accurate due to individual variability, while the perceived exertion equation was more accurate as it reflects the overall exertion of each exercise rather than specific muscles. These equations provide a new tool to convert loads between exercises over a training period.
The Effects of Heel Lift Height on Back Squat Performance
1) The study examined the effects of different heel lift heights (0.64 cm, 1.27 cm, 2.54 cm, 3.18 cm) on back squat performance and biomechanics in one male participant.
2) Preliminary results found that trunk lean was lowest at heel heights above 0.64 cm, suggesting weightlifting shoes with heels over 0.64 cm may reduce risk of back injury during squats.
3) Increasing heel height reduced ankle range of motion but increased peak ankle flexion, indicating a more vertical shank position conducive to proper squat form. Knee displacement did not significantly change with heel height.
Trans2009
This study examined the effects of whole body vibration (WBV) exercise on muscle strength and proprioception in females with knee osteoarthritis. Fifty-two female patients were randomly assigned to one of three groups: 1) WBV exercise on a balance board, 2) WBV exercise on a stable platform, or 3) a non-exercise control group. The WBV groups underwent twice weekly sessions for 8 weeks that progressively increased in intensity. The study found that muscle strength significantly increased in the stable platform group compared to the control group. Proprioception significantly improved in the balance board group compared to the control group. WBV exercise provided benefits to muscle strength and proprioception in females with knee osteoarthritis.

The study examined the effects of calf muscle stretching in weight-bearing and non-weight-bearing positions. It found that non-weight-bearing stretching significantly increased muscle fascicle length and Achilles tendon length compared to weight-bearing stretching. Weight-bearing positioning limits the muscle's ability to relax fully and elongate due to forces from the body weight. Non-weight-bearing stretching allows for greater lengthening of both the muscle and tendon tissues. The results suggest non-weight-bearing calf stretching may provide greater benefits for improving ankle mobility.

This document discusses views on species protection from the perspective of practitioners. It covers how the law has evolved to protect species since the 1970s, moving from resource protection to protecting individual species. Licensing is now used to control predators when best practices fail to protect prey populations. Evidence is gathered to determine if removing a predator will solve problems. Statutory agencies and central government should clarify their separate but linked roles in both production and conservation to prevent species decline. Licenses should be used boldly as part of adaptive management.

Dot matrix Analysis Tools (Bioinformatics)
Sequence alignment involves arranging DNA, RNA, or protein sequences to identify similar regions and infer functional or evolutionary relationships. Dot matrix alignment visually represents the similarities between two sequences in a grid, where dots indicate matching characters. Software like LALIGN, DOTLET, and DOTMATCHER can perform dot matrix alignments, calculating scores based on factors like gap penalties to identify significant matches despite differences. Dot plots can reveal similarities like inverted repeats or palindromic sequences.

Beyond "The Crisis in Civics"
This document discusses civic participation and activism. It suggests that if we want civic participation that is meaningful, impactful and scalable, we should:
1) Move beyond viewing politics and activism as separate, and instead focus on empowering individual agency.
2) Understand the different levers for change, like legislation, authority and public opinion, as well as developing new tactics.
3) Deepen people's foundations of understanding on issues while also increasing their engagement through actions like petitions, protests, and social media.
4) Recognize that thick, impactful civic participation at a large scale requires distributing control and leadership broadly throughout communities.

New classical analysis of
The document discusses several concepts from New Classical economics including:
1) How an underprediction of inflation could cause an increase in employment if it leads to a higher real wage.
2) How a rise in aggregate demand could cause a rise in national output if expectations are wrong and the short-run aggregate supply curve shifts out.
3) How a rise in aggregate demand could cause a fall in national output if expectations are correct and the long-run aggregate supply curve is vertical.
4) How the short-run Phillips curve varies depending on whether inflation expectations are lower than, equal to, or higher than actual inflation.

A Line is a Dot That Went for a Walk
The document is a story told through slides about a little dot that goes for a walk and makes different types of lines. As it walks, it creates straight lines, dotted lines, zigzag lines, curved lines, wavy lines, thin lines, heavy lines, and dashed lines. It gets tired and goes home to bed. Children are instructed to draw each type of line, and then turn their lines into a picture by adding more lines and coloring it in. The story teaches kids about different line types through a creative narrative.
Salem dot game
The document describes a classroom activity called "The Dot Game" that aims to simulate the Salem Witch Trials. Students receive a paper with either a dot or being blank, with more students having blank papers. Those with dots must pretend they don't while blank students try to identify the dots. After five minutes, the teacher debriefs students on their strategies and experiences being accused of being a dot. Finally, a t-chart compares aspects of the game to actual events in Colonial Salem in 1692 during the witch trials.

Dot-Com Crash
The document discusses the dot-com bubble of the late 1990s. It describes how a rise in internet usage led to the founding of hundreds of dot-com companies and speculative investing. The bubble peaked in 2000 and then burst as many companies failed or went bankrupt due to unrealistic business plans and a decline in IT spending. While some internet companies survived, the bubble collapsed the valuations of many others and caused massive losses in the stock market. The document also considers whether a "Bubble 2.0" may be forming around Web 2.0 and social media companies.

Paper 01 emg abdominal escamilla feb 2006
This study analyzed muscle activation in the abdomen and other areas of 7 commercial abdominal machines (Ab Slide, Ab Twister, Ab Rocker, Ab Roller, Ab Doer, Torso Track, SAM) and 2 common exercises (crunch, bent-knee sit-up) using electromyography. The results showed the Ab Slide and Torso Track activated abdominal muscles the most while minimizing back and hip muscle activation. Exercises like the Ab Doer, Ab Twister, and bent-knee sit-up activated back muscles more and may irritate existing back issues. Overall, different exercises activated various muscles to different degrees, providing information to help address individual rehabilitation or training needs.
Effect of Sit To Sit And Activity On Forward Bending Test
Sit-to-stand activity was found to be an effective pre-stretching tool to improve flexibility of the lower back, hamstrings, and Achilles tendon muscles based on this study of 50 females. Participants were divided into two groups that performed either 10 or 20 repetitions of sit-to-stand activity. Both groups had statistically significant improvements in flexibility as measured by increased forward bending distance and decreased muscle tightness. However, there was no significant difference found between the two groups, suggesting that 10 and 20 repetitions were equally effective. The study concluded that sit-to-stand activity provides warm-up and increases flexibility through mechanisms of reciprocal inhibition and autogenic inhibition.
Muscle ultrasound for nutritional
1) Muscle ultrasound can be used to assess muscle mass and quantify sarcopenia. It has advantages of being non-invasive, portable, and radiation-free compared to other imaging techniques.
2) Key measurements include muscle thickness, cross-sectional area, and anatomical or physiological cross-sectional area. Standardized protocols and anatomical landmarks are important for reliability.
3) Common sites measured are the quadriceps (rectus femoris) and gastrocnemius muscles. Measurements of the upper arm can also provide insights into muscle wasting.
core muscle strengthening
The core muscles can be categorized as stabilizers or mobilizers. Stabilizers like the transversus abdominis and multifidus are deeply placed, have slow twitch fibers, and help provide stability. Mobilizers like the rectus abdominis are more superficial and have fast twitch fibers for movement. Chronic low back pain is associated with weakness in the transversus abdominis and multifidus as well as decreased flexibility. A core strengthening program focuses on training these local stabilizer muscles in three stages: 1) local segmental control, 2) closed chain exercises, and 3) open chain exercises and functional progression. Exercises target the transversus abdominis, multifidus, and glute

(1) EMG is used to directly measure pelvic floor muscle function and innervation for evaluating and treating dysfunctions like incontinence. (2) A 4-channel EMG system measures the pelvic floor and surrounding muscles during standardized tests to analyze coordination and identify issues. (3) Biofeedback training then focuses on re-educating the pelvic floor muscle through isolated activation exercises and integrating it into whole body movements and daily activities. (4) Retests assess changes in muscle activation, endurance, and coordination from the training.
Sf n 2016
Simone Toma proposes a method to quantify the contribution of central motor signals to force perception. The method correlates muscle activity (EMG) recorded from 8 arm muscles with subjects' responses during a force detection task. Logistic regression was used to build "muscle-metric curves" from weighted EMG data and compare them to subjects' "psycho-metric curves" based on responses. Muscle-metric curves explained up to 60% of the variability in subjects' responses, supporting the role of central motor signals in force perception. Model selection found that curves from as few as 3 muscles captured key features, and muscle synergies reconstructed perceptual probabilities, further linking muscle coordination to force perception.
The Physiology of Sun Salutation (Surya Namaskar)
This document summarizes a study that used PET/CT imaging to identify the skeletal muscles activated during sun salutation (Surya Namaskar). The study found the most intense uptake and activation in the shoulders and anterior abdominal muscles, specifically the deltoid, infraspinatus, triceps, serratus anterior, and rectus abdominis muscles bilaterally. Other muscles that showed increased uptake included the tibialis anterior. This indicates that sun salutation primarily exercises the shoulders and abdominal muscles. The study provides evidence that PET/CT imaging can effectively identify muscle recruitment during yoga exercises.
effect of tens on hand function in hemiplegic patient
The study aimed to determine whether transcutaneous electrical nerve stimulation (TENS) can effectively improve hand function when used as an adjunct to physical therapy for post-stroke hemiplegic patients. 30 subjects were randomly assigned to receive either real TENS or placebo TENS with conventional physical therapy for 3 weeks. Both groups showed significant improvement in hand function as measured by Fugl-Meyer Assessment and Action Research Arm Test scores. However, the real TENS group demonstrated greater functional gains compared to the placebo group. The findings suggest that TENS is an effective and well-tolerated adjunct for improving hand function in post-stroke hemiplegics when added to conventional physical therapy.

Da silva et al. 2008 leg press
This study analyzed muscle activation in the legs during different variations of the leg press exercise at submaximum effort levels. Fourteen women performed three variations of the leg press - 45° leg press, high leg press, and low leg press - at 40% and 80% of their maximum weight. Electromyography was used to measure muscle activation in the rectus femoris, vastus lateralis, biceps femoris, gastrocnemius, and gluteus maximus muscles. The results showed that mechanical changes and load levels affected muscle activation patterns. At moderate effort, the rectus femoris and gastrocnemius were more active in the 45° and low leg presses compared to the high leg press. At high
PHYSIOTHERAPY MANAGEMENT OF ROTATOR CUFF TENDINOPATHY
MANAGEMENT OF ROTATOR CUFF TENDINOPATHY
INTRODUCTION.
The rotator cuff are group of muscles and tendons that surround the shoulder joint, keeping the humerus bone firmly within the shallow socket of the scapular. A rotator cuff tendinopathy can cause a dull ache pain in the shoulder that worsens at night.
Physiotherapists has a fundamental role in the management of rotator cuff pathology, whether the choice is conservative or surgical treatment, inform of exercises and use of therapeutic modalities.
Exercise therapy program is tailored to each patient's capabilities at a given session the physiotherapist adjust exercise intensity as determined by the patient's ability.

3 Entrenamiento potencia
Este estudio comparó dos programas de entrenamiento de fuerza que solo difieren en la pérdida de velocidad permitida en cada serie: 20% (VL20) vs 40% (VL40) sobre las adaptaciones musculares estructurales y funcionales. Ambos grupos mejoraron la fuerza máxima y el volumen muscular, pero VL20 obtuvo mayores ganancias en salto vertical a pesar de realizar menos repeticiones, mientras que VL40 indujo una mayor hipertrofia muscular y redujo en mayor medida el porcentaje de fibras musculares de tipo II
1 Introduccion potencia
1. Training to failure is less effective for improving performance than training that does not reach failure, as it produces excessive metabolic and mechanical fatigue.
2. Reaching failure results in a very high loss of speed in the series and a transition to slower fiber types, reducing explosive force production capacity.
3. When assessing power, the goal is to improve velocity at a given load to increase power, not just improve absolute power, which is not a direct indicator of performance improvement. All training is focused on improving execution speed or explosive strength.
Dorsal
This study evaluated 323 participants for thoracic kyphosis and measured their lung function through spirometry tests. 130 participants (40.2%) were diagnosed with thoracic kyphosis. Those with kyphosis had lower lung volume and air flow as measured by FVC% and FEV1% compared to those without kyphosis. The lung function deficit was proportional to the severity of the kyphosis. The study concluded that kyphosis is associated with shortness of breath and restrictive or obstructive ventilatory dysfunction in the elderly.
