The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete's sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males' maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics.
向前滑冰起跑是男女冰球运动员的一项基本技能。然而，运动员性别导致的表现差异不能完全由生理变量来解释；因此，诸如滑冰技术等其他因素值得研究。所以，本研究的目的是评估精英男女冰球运动员在冰球滑冰起跑时的身体运动学。9名男性和10名女性精英冰球运动员进行了5次向前滑冰起跑加速。一个放置在冰场冰面上的18台摄像机的动作捕捉系统，在15米内的前七个滑冰起跑步骤中捕捉全身运动学数据。男性的最大滑冰速度高于女性。注意到了滑冰技术的性别差异：特别是，女性在整个滑冰姿势中髋部外展角度比男性低约10°，并且在最初接触冰面时膝关节伸展角度比男性大10°左右，明显的是在接触冰面瞬间膝关节伸展有短暂停顿，这在男性滑冰者中不明显。有必要进行进一步研究，以解释与训练、装备、表现水平和人体测量学等因素相关的这些滑冰技术差异为何存在。
