Unique requirements of field hockey include dribbling the ball and moving quickly in a semi-crouched posture. First, the net physiological strain due to dribbling was examined. Seven male hockey players completed a 5 min run on the treadmill at 8 km h-1 and 10 km h-1: subjects also ran at these speeds whilst dribbling a hockey ball. Dribbling increased energy expenditure by 15-16 kJ min-1 above that observed in normal running. Heart rates and perceived exertion were also increased. The posture in dribbling is likely to cause back ache among players: 53% of respondents (n = 81) reported experience of lower back pain. Finally, the shrinkage of spinal length during dribbling was examined. Subjects (n = 7) ran for 7 min on the treadmill whilst dribbling a ball. Shrinkage occurred at a rate of 0.4 mm min-1, which is greater than previously reported for other activities. The peculiar postural requirements of field hockey seem to cause physiological strain and spinal loading in excess of orthodox motion.
曲棍球的独特要求包括运球以及以半蹲姿势快速移动。首先，研究了运球导致的净生理压力。七名男性曲棍球运动员在跑步机上以8公里/小时和10公里/小时的速度完成了5分钟的跑步：受试者还在运球时以这些速度跑步。运球使能量消耗比正常跑步时观察到的增加了15 - 16千焦/分钟。心率和自觉用力程度也有所增加。运球时的姿势可能会导致球员背痛：53%的受访者（n = 81）报告有下背部疼痛的经历。最后，研究了运球过程中脊柱长度的收缩情况。受试者（n = 7）在跑步机上运球时跑了7分钟。收缩速率为0.4毫米/分钟，这比之前报道的其他活动的收缩速率要大。曲棍球独特的姿势要求似乎会导致生理压力和脊柱负荷超过传统运动。
