Skeletal muscles are among the most used in sports besides the cardiac muscle which is the heart. Skeletal muscles are the muscles that are connected to your bones which help you function your normal task like shooting a basketball, walking, or even holding your remote.
The research on skeletal muscles had begun since the last decade for the purpose of understanding on how the muscle works. The skeletal muscle has a total of three movements or stages. One is known as a contraction which supplies the work. An example would be lifting a book. Then there is isometric which is work without movement. It is easily understand if you place both of your hands against a wall and pushed. That is an example of isometics. Finally there is eccentric in which your muscles are at rest.
For each muscle group, there are muscle fibrers that extend an entire length of the muscle. The muscle fiers contain myofibrils that store a high concentration of calcium ions in the sarcoplasmic reticulim. Transverse tubules are contained in the myofibrils that are crucial to the control of the muscle contration which was found by Audesirk in 1993. Filaments inside the muscle cells contain actin and myosin. Actin and myosin are two different strands of protein. Whenever the muscle works either though contraction or isometric, the two protein strands are combines and ATP (adrenotriphosphate) would be released through crossbridging. Meaning coming together and splitting apart. The work are controlled by the concentraion of calcium ions that are in the filaments that is under control by the nervous system. From this, stimulation through the synaptic contract to neurons, which are sent to the spinal nerves. After that, the spinal nerve tells the muscle that an action could be accomplished.
The strength and extent of muscle contraction depend on the rate of potential strength in the motor neuron. Due to calcium flow and frequency fo the muscle c
