imbalances or tissue damage, hence the loss of the ability to contract, or muscle fatigue.…
no doubt we all believe that exercise is a magical key to lead a long and healthy life. Exercise has several benefits on our mind and body. By doing exercise regularly, the can stay away from a lot of body ailments which are a must with the advancing age. For seniors following an exercise routine is the ideal way to enhance their energy level and is stay fit.…
Because motor neurons degenerate with ALS, they can no longer send impulses to the muscle fibers that normally result in muscle movement. Early symptoms of ALS often include increasing muscle weakness, especially involving the arms and legs, speech, swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function, the muscles begin to become smaller. Therefore limbs begin to look "thinner" as muscle tissue atrophies.…
During exercise your muscles are put under stress due to constant contractions this stress can then lead to tears in the muscle fibres, if the body has the correct nutrients during recovery periods the muscle can then repair itself and become stronger this can lead to a increase in muscular endurance.…
The onset of muscle fatigue has hindered many athletes from achieving their maximum performance. Over the years we have been taught that it is the build-up of lactic acid that is the downfall of muscle fatigue and soreness. This is only partially true; there is a little more to it than what we have been told. I hope that this article provides you with a possible short-term remedy and does not confuse you more but rather makes you more aware of what is going on when your muscles become fatigued. During short term (anaerobic) exercise, ATP and creatine phosphate (CP) are used up within the first 7 seconds of training. This signals the metabolism of glycogen to produce energy for your body.…
Atrophy is the decrease in cell size due to stress or injury. If enough cells undergo atrophy, an entire organ can become atrophic. There are two types of atrophy: physiological and pathological. Physiological atrophy occurs during early development while pathological atrophy can be caused by a number of factors including aging, disuse, and malnutrition. As a person ages, his or her brain and endocrine-dependent organs undergo atrophy and begin to shrink. People who are paralyzed or confined to bed undergo skeletal muscle atrophy due to lack of use. Atrophy due to malnutrition induces autophagic vacuoles, a type of vacuole that destroys other cells.…
Muscle Fatigue is when a muscle gets tired and does not have the ability to generate a force. It can occur because of too much vigorous exercise (aerobic respiration). Lactic acid is produced when there is a high demand for energy, when there is too much the body gets tiresome and weakens the muscle. (3)You can get rid of lactic acid by doing the right amount of exercise that your body needs and doing it periodically.…
Muscles work like levers and allow the bones at a joint to work like hinges. Muscles pull and move the bones at particular joints; this makes the joint move and therefore the body moves. When a muscle contracts, it pulls the bones at a joint in the direction that it is designed to move. With reduced mobility, muscles can become floppy and make movement slower and more difficult, but when muscles are used on a regular basis, they remain firm and move…
Any athlete has surely experienced a muscle cramp before and can tell you the indescribable pain they emit. The main question is what is a muscle cramp and how is it caused. Someone who frequently undergoes muscle cramps may also wonder ‘how do I prevent these?’ Muscle cramps can be a nuisance and may stope athletes or everyday people from doing what they like.…
Muscular Dystrophy is a disorder that is passed down through families, and can occur in both adulthood, and childhood. There are multiple types of Muscular Dystrophy such as Becker MD, Duchenne MD(deadly), Emery-Deifuss MD, Facioscapulohumeral MD, Limb-Girdle MD, Myotonia MD, Mytonic MD etc.. Symptoms related to muscular dystrophy inlcue muscle weakness(slowly gets worse over time), delayed development to muscle motor skills, loss of strength in a muslce/group of muscles, loss in muscle size, difficulty of using more than one muscle group, and possible mental retardation(only present in some cases of muscular dystrophy). In some cases, it is even known to cause scoliosis.…
Because patients with muscular dystrophy are especially susceptible to muscle damage, Physical Therapists, who are skilled in the involvement of skeletal muscle and the effects that skeletal muscle has on joints, are Ideal clinicians to care for patients with muscular dystrophy. 2 Physical therapy is most successful when it is began as soon as possible, preferably right after receiving a diagnosis. This way the physical therapist can teach skills and begin interventions before severe joint tightness, muscle tightness, or contractures develop. 1,2 “Light to moderate exercise has been shown to be benefit patients with muscular dystrophy by slowing down the progression of muscle weakness”, however “Over exercising can damage muscles.” 1,2 Maximal…
A common cause of disuse atrophy is having a cast put on to immobilize a part of the body. Having a muscle group immobilized prevents an individual from being able to use that muscle causing it to weaken and possibly begin to shrink depending on the amount of time the muscles are not being used. An athlete might develop disuse atrophy recovering from an injury like a torn ACL. In both of these scenarios the muscle are significantly weakened after the recovery period. Blood flow restriction training is a form of therapy that can be used in both of these…
Soccer is one of the most demanding physical high intensity field games played all over the world. The increasing demand to increase a player’s physical ability both at professional and amateur soccer has grown in recent years. The development of strength and power is paramount to success in most sports, especially those involving short-term, high-intensity efforts. Traditional Strength training programs improve the development of speed & power (Hakkinen and Hakkinen 1993; Rhea et al. 2003) and stability in an athlete leading to the possibility of better kicking performance, though it is important to recognize the role of strength in power Rostgaard et al. (2008). In a normal week amateur players train on average between 2 to 3 hours, these…
Vascular dementia is a common cause of dementia in the elderly. Dementia is a condition that affects the brain and causes people to not think well or act normally. Vascular dementia is one type of dementia. It occurs when blood clots block small blood vessels in the brain and destroy brain tissue. Likely risk factors are high blood pressure and advanced age. This disease can cause stroke, migraine-like headaches, and psychiatric disturbances.…
I am a female bodybuilder. To me, bodybuilding means realizing the beauty and strength the body is capable of achieving. What for many is a solely an aesthetic venture has become my daily tribute to the human body as a functional unit. Muscles are beautiful because each microscopic filament forms slowly and deliberately through systematic contractions in training. I get stronger. I lift heavier.…
