Introduction
The aim of this acute and chronic report is to identify and analyse the acute and chronic adaptations across 3 psychological systems and how the body’s response differs between the before and during process of aerobic exercise in which it is argued it ‘requires more energy –and hence more oxygen’ (Franklin, 1998, pp.352). These systems are: the cardiovascular which includes the heart and blood flow, the respiratory which monitors oxygen and carbon dioxide and the muscular which examines how the muscles respond to minimum or extensive exercise.
Acute Cardio Vascular Response
Prior to exercise, a reflex stimulation of the nervous system causes the heart rate to intensify. At the start and then later during the exercise an increase in the hearts beating per minute intensifies due to the movement and blood circulation required around the body. The increase in the heart rate can depend on the athlete’s fitness level, age and the addition to exercise workload. …show more content…
It can then be said that other causes of increased blood flow can include the ‘skeletal muscle pump’ (Gonzalez, 2008) which are known as muscular contractions in the body combined with one-way venous valves which pump more blood to the heart and the body during exercise in order to maintain stamina and blood circulation, and ‘the respiratory pump’ (McArdle, 2014) which causes an ‘increased respiratory frequency and tidal volume’ (McArdle, 2014). When the volume is then increased, Guyton says that ‘the fibres become more stretched than at rest resulting in a more forceful contraction’ (Guyton, 2000) because of the strain the body and heart is placed under during a vigorous exercise
