Muscle weakness

Dystrophin is a protein that is located in muscles that work with movement. The job of Dystrophin is to produce muscle proteins that protects the skeletal, cardiovascular and nervous system. Dystrophin plays an important role in protein complex that work together to strengthen muscle fiber and help prevent injuries. It also plays a role in cell signaling between proteins and chemical signals. However its main job is connecting and weighing down each structural framework between proteins and…

is progressive disease of the muscle, caused by defective or absent glycoprotein, dystrophin, in the membrane of the muscle wall. Dystrophin reinforces the myotube membrane skeleton by increasing its stiffness, thus a lack of dystrophin causes substantial reduction in muscle stiffness. Symptoms include ambulation difficulties, hyperopia and gross motor milestone delays in infants and children, calf hypertrophy, an imbalance in lower limb strength, and diminished muscle tone. It occurs in 1 in…

Touch football is a physically demanding sport requiring the extensive use of many systems of the body. It is important for an athlete to properly train and develop these energy systems to perform to their highest potential. I have constructed a training program in order to develop upon my two weakest areas, muscular power and the combination of speed and agility. The average to poor results I received during fitness testing reflected my performance in the vertical jump test, 40m sprint, and the…

Skeletal muscle is a highly specialized, post-mitotic tissue that must withstand chronic mechanical and physiological stress throughout life to maintain proper contractile function. Muscle damage or disease leads to progressive weakness and disability, and manifests in more than 100 different human disorders, including DMD, the most common X-linked genetic disorder in humans, and BMD. Current treatment options for muscular dystrophies are disappointingly limited and focus mainly on managing…

Myasthenia Gravis is a chronic autoimmune disorder that causes weakness and rapid fatigue in the skeletal muscles, these muscles are responsible for breathing and moving. Some of the muscles affected include, control of eye movements, facial expressions, chewing, talking and swallowing. Other symptoms would include, shortness of breath, weakness in arms, hands, fingers, legs and neck. Myasthenia Gravis is a rare disease that may be difficult to diagnose. Myasthenia Gravis occurs when there is an…

resulting in respiratory muscle weakness that can lead to Impaired spontaneous Ventilation. MG starts from the head and moves downward to the toes and is an autoimmune disorder where acetylcholine receptors are blocked by antibodies. Acetylcholine normally causes an excitatory effect at the neuromuscular junctions. The client will usually seek a physician's help because they…

very well known for improving performance. Most ergogenic aids affect the metabolism and the central nervous system to reduce body fat content and stimulate protein synthesis to increase muscle mass or create lean body mass. One of the most used supplements among athletes is creatine, commonly used for increasing muscle mass. As some athletes might not even know, caffeine is also considered as a helpful ergogenic…

a growth phase. The chronic pain in the knee , front and central, is more common among adolescents, especially girls. We can observe symptoms such as knees "squeak" pain at night, or performing exercises that involve constantly flexing the knee, weakness or even collapse. In this case it is not due to any fault of the knee , not necessarily damage with daily activity. The causes may…

Some of these symptoms don’t even happen right away, but it takes time for it to kick in. When a child is going through their early childhood stage, there are some symptoms are going to be discovered, for example, the first effect happens at the muscles of the tips, pelvic area, thighs and shoulders. The calves may end up being enlarged, and the child could be clumsy and fall down easily. They also have a hard time climbing the stairs, getting from the floor, or even running. In order for them…

oxygen and it also speed up the heart allowing the oxygen to be transported to the muscle faster. The human body cannot keep up with this for long. Eventually the heart and lungs reach their maximum work efforts and it can only neutralize the lactic acid for a short period of time. This buildup of lactic acid is what causes the muscles to feel fatigued and soar the next day. Once the acid production stops the muscle start to recover until the acid balance is restored. (citation). Something else…
