Muscle contractions tend to be smooth and vary in strengths‚ depending on the demands placed on them. The variations of strength are called graded muscle responses. There are two ways a muscle contraction can be graded‚ either by changing the frequency of stimulation or by changing the strength of the stimulation. When a muscle is responding to a change in stimulus frequency‚ the nervous system will reach a greater muscular force when increasing the firing of motor neurons. This causes a wave or

performance of the athlete both in physical and mental terms. The athlete needs to learn to notice the signs of fatigue and tension that arises from this and introduce methods to cope with the debilitating effect it can have on their performance. Muscle fatigue and the tension associated with it can result from a number of different factors. The athletes may simply have over exerted themself physically in training or competition leading to muscular fatigue from pushing their physical limits. They

Comparing the Cardiac muscle and the Skeletal muscle Differences Similarities Skeletal muscle is usually linked to bones by structures called tendons. Cardiac muscle is found in the heart. They are both important parts to the body. Skeletal muscle cells are usually arranged into cylindrical fibres with multiple nuclei and can be directly controlled by voluntary nerve signals from the nervous system. Cardiac muscle cells are normally shorter and are linked via gap junctions which allow compounds

Regarding Muscles Vitamin D deficiency has been tied to mainly bone pathologies. Recent research shows that the effects of Vitamin D span further than just affecting bones and particularly cause muscle weakness. Vitamin D is responsible for aiding in the absorption of other minerals‚ such as calcium. Calcium is a key ligand in muscle contractions‚ thus‚ Vitamin D indirectly can effect muscle contractions.
