In this study, the intensities of activity and movement patterns during men's basketball were investigated by videoing the movements and monitoring the heart rate and blood lactate responses of eight elite players during competition. The results are expressed according to 'live time', which is actual playing time, and 'total time', which includes live time as well as all stoppages in play. The mean (+/- S.D.) frequency of all activities was 997 +/- 183, with a change in movement category every 2.0 s. A mean total of 105 +/- 52 high-intensity runs (mean duration 1.7 s) was recorded for each game, resulting in one high-intensity run every 21 s during live time. Sixty percent of live time was spent engaged in low-intensity activity, while 15% was spent in high-intensity activity. The mean heart rate (HR) during live time was 169 +/- 9 beats min-1 (89 +/- 2% peak HR attained during laboratory testing); 75% of live time was spent with a HR response of greater than 85% peak HR. The mean blood lactate concentration was 6.8 +/- 2.8 mM, indicating the involvement of glycolysis in the energy demands of basketball. It is concluded that the physiological requirements of men's basketball are high, placing considerable demands on the cardiovascular and metabolic capacities of players.
在本研究中，通过拍摄男子篮球比赛中八名精英球员的动作，并监测他们的心率和血乳酸反应，来调查男子篮球比赛期间的活动强度和运动模式。结果根据“实时时间”（即实际比赛时间）和“总时间”（包括实时时间以及比赛中的所有停顿时间）来表示。所有活动的平均（±标准差）频率为997±183次，每2.0秒运动类别发生一次变化。每场比赛平均总共记录到105±52次高强度跑步（平均持续时间1.7秒），在实时时间内每21秒就有一次高强度跑步。60%的实时时间用于低强度活动，而15%用于高强度活动。实时时间内的平均心率（HR）为169±9次/分钟（占实验室测试中达到的峰值心率的89±2%）；75%的实时时间内心率反应大于峰值心率的85%。平均血乳酸浓度为6.8±2.8毫摩尔，表明糖酵解参与了篮球运动的能量需求。研究得出结论，男子篮球的生理需求很高，对球员的心血管和代谢能力提出了相当高的要求。
