Introduction The cardio-respiratory system is called upon towork hard during physical activity.It must take in air, extract oxygen, circulate blood quickly tosupply oxygen, water and nutrients to the muscle cells aswell as take carbon dioxide and wastes away from the cells andbreathe out to expel the carbon dioxide.Participate in an aerobic workout or sport and […]

Introduction Heart rate increases in response to exercise as the demand for oxygen to working muscles increases. The rise in heart rate continues to maximal levels, although if the activity is sub-maximal the heart rate will stabilise or reach a steady state. If the intensity of the exercise increases the heart rate will rise to

Introduction Maximal oxygen uptake ( VO2 max. ) is the maximum rate at whichoxygen can be consumed per minute, per kilogram of body weight. VO2 max. = Cardiac output X arteriovenous oxygen difference.Maximal oxygen uptake is used as the most accurate measure ofa person’s aerobic power or fitness.A higher VO2 max. reflects an increased ability
