 * Unit 3 Key Knowledge:**


 * a)** The mechanisms responsible for the acute responses to exercise in the cardiovascular, respiratory and muscular systems.


 * b)** Characteristics and interplay of the three energy systems (ATP-CP, anaerobic glycolysis, aerobic system) for physical activity, including rate of ATP production, the capacity of each energy system and the contribution of each energy system.


 * c)** Fuels (both chemical and food) required for resynthesis of ATP during physical activity and the utilisation of food for energy.


 * d)** Relative contribution of the energy systems and fuels used to produce ATP in relation to the exercise intensity, duration and type.


 * e)** Oxygen uptake at rest, during exercise and recover, including oxygen deficit, steady state and excess post-exercise oxygen consumption.


 * f)** The multi-factorial mechanisms (including fueld depletion, metabolic by-products and thermoregulation) associated with muscular fatigue as a result of varied exercise intensities and durations.


 * g)** Passive and active recovery method to assist in retuning the body to pre-exercise levels.
