Hypertrophy Hypertrophy is the enlargement of an organ or tissue from the increase in size of its cells. For example, muscle is made out of fibers and those fibers are made up of a ton of thicker fibers. So when they bond together they make tight bundles of tissue. Also there are two types of fibers there are fast twitch and slow twitch. The fast twitch fibers are for endurance and the slow twitch are for strength.For example a sprinter has more fast twitch fibers.So a distance runner has more slow

Duchenne muscular dystrophy is an inherited neuromuscular disorder that affects the musculoskeletal system, and is caused by a genetic mutation which disrupts the production of dystrophin. It causes progressive loss of muscle mass and eventually leads to death of the muscle tissue. The main symptom of muscular dystrophy is progressive muscle weakness. However, different signs and symptoms begin at different ages and in different muscle groups depending on the specific type of muscular

1. Arteriosclerosis is the hardening of the arteries due to the plaque buildup and causes blockage of the blood flow. So if Arteriosclerosis happens in the carotid arteries it will reduce the blood flow and in return less oxygen will go to the brain. Once you deprive your brain of enough oxygen it will cause major problems and may lead to stroke and/or brain damage. 2. Rigor mortis causes the body to go stiff. It is due to an influx of calcium ions into muscle cells and promotes the cross-bridge

24 November 2013 Genetics and Muscle Growth An individual's genetic profile can play a role in defining their natural skills and talents. Muscle growth is one of those things that can be defined by genetics. Genes determine between 20-80% of the variation in traits like oxygen intake, cardiac performance, and muscle fiber composition. More than 150 genes have been linked to different aspects of physical performance. (Yang, MacArthur, & North, 2003) The amount of muscle growth that develops

goalkeeper’s position, the fitness components a goalkeeper needs to train are the likes of muscular power, speed, strength, flexibility, reaction time and agility. For the likes of these fitness components, a goalkeeper relies mostly on the ATP-PC energy system. There may be times however when the Anaerobic Glycolysis system may be required if there is not adequate time between bouts to restore ATP. Muscular Power: This fitness component is a major part of being a goalkeeper as it is required almost

I have been tasked with writing a paper about amyotrophic lateral sclerosis (ALS). The ALS Association website has described ALS in a very clear and concise manner and I would like to share that with you know. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the

Scholars have been conducting studies on the physical differences between white and black athletes for many decades. However, there is still no concrete evidence that these physical differences are the contributing reason for the so-called athletic superiority of blacks. In a study published in the journal "Medical & Science in Sports & Exercise," the architectural characteristics of muscle in black and white college football players were compared. This study was conducted by Professor Takashi

Anatomy and Physiology 2, SCI 136 Research project # 40904000 Muscular Dystrophy Definition Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. The word dystrophy is derived from the Greek dys, which means "difficult" or "faulty," and troph, or "nourish." These disorders vary in age of onset, severity, and pattern of affected muscles. All forms of MD grow worse as

How to Prevent Cramps Cramps are usually associated with muscle fatigue and/or dehydration with an associated loss of electrolytes. There are two ways to get cramps: skeletal muscle overload and fatigue and excessive sweat losses associated with a decreased level of electrolytes (specifically sodium). 1. Have a hot shower or bath. This will improve blood circulation and help the connective tissue around the muscles. 2. Need calcium. You can find good source of calcium in low-fat dairy
