activities of daily living. PNF is a type of passive stretching that uses alternating contraction and relaxation movements to increase flexibility. The reason why PNF is better than other forms of flexibility training is that it helps the body’s muscular inhibition. For the elite performer‚ the most useful type of PNF is the CRAC (contract-relax‚ antagonist-contract) technique‚ which uses isometric muscle contractions as its basis. PNF stretching is best performed with a partner. Muscle recruitment

Cyril MIller Per.6 Spinal Muscular Atrophy Spinal muscular atrophy is a group of inherited diseases that cause muscle damage and weakness‚ which get worse over time and eventually lead to death. Causes: Spinal muscular atrophy (SMA) is a collection of different muscle diseases. Grouped together‚ it is the second leading cause of hereditary neuromuscular disease‚ after Duchenne muscular dystrophy. Most of the time‚ a person must get the defective gene from both parents to be affected. About 4

Body in Action – Muscular System Roughly 40% of your body mass is made up of muscle‚ the key purpose of which is to move the bones of your body. In this assignment muscle movements and short and long term responses to exercise will be looked at. Types of Muscle Within the body‚ there are three different types of muscle. 1. Cardiac Muscle 2. Skeletal Muscle 3. Smooth Muscle Cardiac Muscle This is specialised muscle of the heart (BTEC National Sport Book 1). This is an involuntary type

The Muscular System The body contains 650 muscles that allow the body to move in different ways and also helps with blood flow. There are three types of muscles including: visceral‚ skeletal‚ and cardiac. Visceral muscles are the ones found in organs. This is one of the weakest of the muscle types and is also involuntary. The only voluntary muscles‚ skeletal‚ usually attach near joints. These muscles are considered voluntary because they are physical actions that can be controlled. The last muscle

The forest lake aquathon consists of a 250 meter swim and a 2.5 kilometre run. A specific training program has been made to improve my weaknesses and work on cardiovascular fitness and endurance. This essay will also evaluate the personal training program that has been created and whether or not it will help improve my fitness. In last year’s aquathon I did not participate‚ but the average time that most students finished were around 20 minutes. There was also a fitness test where students swum

Hannah Loback Muscle Essay The muscular system is a network of tissues that controls movement of the human body. Attached to the skeletal system are a multitude of muscles consisting of tissues‚ blood vessels‚ tendons‚ and nerves. Muscles are a bundle of fibrous tissue in the body that have the ability to contract‚ thus producing movement and maintenance of body parts. Without this system the ability to function and maintain a healthy lifestyle would be impossible. Correct posture‚ locomotion‚ and

Muscular Dystrophy‚ also referred to as “MD”‚ is a group of diseases that cause progressive weakness and loss of muscle mass (Mayo). In MD‚ abnormal genes interfere with the production of proteins needed to form the muscle’s health (Mayo). There are many long-term effects to this terrifying disease. The primary one‚ that being unable to walk. Muscular Dystrophy is a life-threatening disease that many pose questions and desire to learn more about. Muscular Dystrophy occurs in various forms. While

Muscular strength describes how strong a muscle is or how much force it can exert. Exercise professionals often measure muscular strength by determining the maximum weight a person can lift at one time. There are 2 components to gain muscles strength; 1) The neural component (short-term). 2) The hypertrophic component (long-term)

Muscular dystrophy (MD) can be described as a group of diseases that cause continuing weakness and loss of muscle mass. (Article 1‚ pg.1) Muscular dystrophy effects homeostasis because abnormal genes (mutations) interrupts the production of proteins that the body needs to form healthy muscle. (Article 1‚ pg.1) The nine major forms of muscular dystrophy are Myotonic‚ Duchenne‚ Becker‚ Limb-girdle‚ Facioscapulohumeral‚ Congenital‚ Oculopharyngeal‚ Distal‚ and Emery-dreifuss.
