The main goal of this study was to compare dominant and non-dominant martial arts palm strikes under different circumstances that usually happen during martial arts and combative sports applications. Seven highly experienced (10±5 years) right hand dominant Kung Fu practitioners performed strikes with both hands, stances with left or right lead legs, and with the possibility or not of stepping towards the target (moving stance). Peak force was greater for the dominant hand strikes (1593.76±703.45 N vs. 1042.28±374.16 N; p<.001), whereas no difference was found in accuracy between the hands (p=.141). Additionally, peak force was greater for the strikes with moving stance (1448.75±686.01 N vs. 1201.80±547.98 N; p=.002) and left lead leg stance (1378.06±705.48 N vs. 1269.96±547.08 N). Furthermore, the difference in peak force between strikes with moving and stationary stances was statistically significant only for the strikes performed with a left lead leg stance (p=.007). Hand speed was higher for the dominant hand strikes (5.82±1.08 m/s vs. 5.24±0.78 m/s; p=.001) and for the strikes with moving stance (5.79±1.01 m/s vs. 5.29±0.90 m/s; p<.001). The difference in hand speed between right and left hand strikes was only significant for strikes with moving stance. In summary, our results suggest that the stronger palm strike for a right-handed practitioner is a right hand strike on a left lead leg stance moving towards the target.
本研究的主要目的是比较不同情况下惯用手和非惯用手的武术掌击，这些情况通常发生在武术和格斗运动中。7 名经验丰富（10±5 年）的右手惯用型功夫习武者用双手、左腿或右腿作为主要支撑腿进行掌击，并且可以或不可以向目标方向移动（移动姿势）。惯用手的击打峰值力更大（1593.76±703.45 N 对 1042.28±374.16 N；p<.001），而双手的准确性没有差异（p=.141）。此外，移动姿势的击打峰值力更大（1448.75±686.01 N 对 1201.80±547.98 N；p=.002），左腿支撑腿的击打峰值力也更大（1378.06±705.48 N 对 1269.96±547.08 N）。此外，只有在左腿支撑腿的移动姿势下，移动和静止姿势的击打峰值力差异才有统计学意义（p=.007）。惯用手的击打速度更高（5.82±1.08 m/s 对 5.24±0.78 m/s；p=.001），移动姿势的击打速度也更高（5.79±1.01 m/s 对 5.29±0.90 m/s；p<.001）。只有在移动姿势下，惯用手和非惯用手的击打速度差异才有统计学意义。综上所述，我们的研究结果表明，对于右手习武者来说，更强的掌击是在左腿支撑腿、向目标方向移动的姿势下用右手进行掌击。
