Aerobic Performance
Aerobic performance is dependant upon the ability of the heart, lungs and vascular system to deliver oxygen and fuels to working muscles and remove the by-products of metabolism (Welsman. ...
It has been shown that younger children consume more oxygen per kilogram of body mass than older children and adults when walking or running at the same speed, (Astrand, 1952; MacDougall et al, 1983; Kranhenbuhl and Williams, 1992; Journal of Sport Sciences 2002, 20, 451-461). ...
Children’s cardiovascular responses to exercise differ markedly from the adult (Welsman. ... However, the higher heart rates cannot fully compensate for the lower stroke volume and so children’s cardiac output, measured in L/min, is lower than adults (Wilmore and Costill, 1994). ... ’ Also supported by Armstrong and Welsman who stated, ‘Maximal heart rate of children and adolescence ranges between 195 – 215 bpm although it is not unusual to observe rates in excess of 220 during maximal exercise.
