Introduction Motor unit recruitment is the sequential activation of motor units to perform a certain task. In this lab we examined motor unit recruitment and muscle fatigue by electromyography (EMG) with dynamometry (DYN). When the motor unit in the muscle is activated signals are then generated‚ which result in muscle contraction. The impulse generated are a bit weak‚ yet can still be detected by the electrodes‚ EMG and is coupled by a measurements of power‚ DYN. When all the motor units reach

The Tryout for Strong and Brawny Glory Hitting the gym to get a fit and fine body is the preliminary goal of a person‚ but as they reach the initial goal the strategy changes and they think about adding more muscles and build size. Therefore‚ people train hard as a high volume workout helps build muscle size as it releases critical anabolic hormones responsible for muscle growth‚ but this is a very slow process and the results take time. So people turn to steroid for help and Super Anadrol is the

In boxing two stances that a fighter can take are southpaw and orthodox. A southpaw fighter stands with their right side in front. An orthodox fighter stands with their left side leading. As southpaws tend to be a rare find many fighters prefer to take the orthodox stance‚ but I rather southpaw because it allows for stronger jabs‚ it allows me to keep up with my stamina‚ and also confuse opponents. Boxing in the southpaw stance has taught me to rely on my right handed jab. Standing with

Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

Outline the differences between the excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction
