The analysis of the results of the current study demonstrated a significant difference between mean change in pulse rate of subjects able to complete less than and greater than than 25 push ups (p < 0.05). The null hypothesis (H0) is rejected and the alternate hypothesis (Ha) retained. This suggests a correlation between aerobic and anaerobic fitness levels in completing high intensity exercise

In tests of endurance, aerobic glycolysis is the major source of energy to the body. The body requires energy at a less intense rate; so slower aerobic glycolysis processes are sufficient to provide ATP over an extended time period (Ghosh 2004). Aerobic fitness depends upon many physiological factors, including density of capillary vessels surrounding lung alveoli, number of mitochondria (site of ATP production) in cells and lung capacity (Bogdanis et al. 1996; Tomlin and Wenger 2002; Ghosh 2004). A greater level of aerobic fitness will result in more efficient oxygen use, so oxygenated blood will not need to be circulated at a much higher rate and pulse rate will not increase significantly. Pulse rate is proportional to the energy required by the body (intensity of exercise) in regards to the aerobic capacity of an individual, so heart rate will increase in accordance to the body’s increasing energy demand during exercise (Åstrand and Ryhming 1954).

In the current study participants undertook a step up endurance activity, in which a pulse rate change was recorded for all
