neurotransmitter that has an inhibitory effect on vertebrate cardiac muscle. The neurotransmitter does this by releasing neurons which activates a signal transduction pathway. As a result‚ the G protein in the pathway stops adenylyl cyclase and opens the muscle cell membrane’ potassium channels. These two actions result in a reduction in the cardiac muscle contraction. Another chemical known as epinephrine has the opposite effect on cardiac muscle. In the wall of the right atrium‚ there is a cluster of cells

2014) Respiratory System This system is responsible for ensuring the body has a constant supply of oxygen‚ whilst removing carbon dioxide. It is made up of six organs and there are three major parts of the system; the airway‚ the lungs and the muscles of respiration. The respiratory system supplies the oxygen needed for the cardiac work load and its main function is gaseous exchange (Taylor‚ T cited in Inner Body). (diagram cited in Buzzle‚ 2014) Breathing volumes

increases the blood circulation. This allows oxygen to reach the muscles. The muscles can now work more efficiently. Warming up improves joint mobility‚ mobilising and loosening exercises lubricates the joints. Stretching the muscles increases the blood flow to them which makes them increase stamina (the amount of work muscles can do before fatigue sets in) and flexibility (the range of movement in the joints which is increased by lengthening muscle fibres). Examples of warm up exercises: 1. Pulse raising

the definition of a fitness test is ‘a test designed to measure physical strength‚ agility‚ and endurance’. Individual Physiological Response to Exercise Fitness Components & Aerobic Dance Strengths: Muscular endurance is the ability to work a muscle for long periods at less than maximum effort where local fatigue rather than general exhaustion is the limiting factor. I would find muscular endurance as one of the fitness components I am strongest at as in the 3RM Bench Press as I lifted above
