摘要：The purpose of this research was to study the energy expenditure during competition Netball.The sample was 12 youth national netball players. They were selected purposive sampling. They weretested to completed a laboratory based incremental electrical treadmill tested to establish maximal oxygenuptake (VO2 max) and wore a Polar Accurex Plus telemetric heart rate monitor during competitionNetball. The heart rate data from competition were compared with heart rate and oxygen uptake datameasured in laboratory. Individual regression equations were established from these data to estimatethe energy expenditure during competition. The result of the research was Netball Players has mean heart rate during competition was 151beats/min. The mean estimated oxygen uptake during competition was 22.16 ml/kg/min whichcorresponded to 65% of the group’s mean maximal oxygen uptake of 34.32 ml/kg/min. The meanenergy expenditure throughout an entire match was 407 kcal. The mean energy contribution of anaerobicsystem, anaerobic – aerobic system and aerobic system were 18%, 60% and 22% respectively. The datawere statistically analyzed by the Kruskal – Wallis One – Way analysis of variance test. It was found that,the energy expenditure during competition by each of the playing positions in Netball was no significantdifferences. This study tends to be the guideline for making recommendations regarding the intensity andtype of exercise that should be employed during training programmes.
