Lim, C, Wee, J, Lee, M, Lim, S, and Leow, S. Validity and reliability of the power slap board as an application to measure upper body vertical pulling power for female water polo players. J Strength Cond Res 38(11): e670-e677, 2024-This study examined the validity and reliability of the power slap test (PS) as an assessment for upper body pulling power to predict water polo functional performance and competitive experience of female water polo players. Seventeen female water polo players from the national and development squads were recruited. Subjects completed test-retest sessions of PS testing and 1 session of functional performance tests for the 15-m arms-only sprint (15 mAOS) and the 5-m maximum shooting velocity (5 mMSV). All PS, 15 mAOS and 5 mMSV results were compared for predictability. Power slap scores demonstrated high reliability for left PS (intraclass correlations [ICC]: 0.96, 90% confidence interval [CI]: 0.91-0.98), right PS (ICC: 0.96, 90% CI: 0.90-0.98), left and right center of mass (COM) displacement (ICC: 0.98, 90% CI: 0.96-0.99; ICC: 0.95, 90% CI: 0.88-0.98), and summed PS (ICC: 0.96, 90% CI: 0.92-0.99). All absolute PS scores and left COM displacement (COM disp L) demonstrated large correlations with the 15 mAOS times ( r = -0.542 to -0.52, r2 = 0.27-0.29, p < 0.05). No performance parameters of the PS were correlated with the 5 mMSV performance ( p > 0.05). This study validates the reliability of the PS as a dryland assessment tool for upper body pulling power. Only absolute PS scores and COM disp were validated as weak predictors of the arms-only sprint times over 15 m. Its predictive power significantly improved when considered in combination with shooting performance. All absolute and normalized kinetic and kinematic PS parameters did not predict functional performance and competitive experience.

Lim, C, Wee, J, Lee, M, Lim, S, and Leow, S. 干板功率拍击测试作为测量女性水球运动员上肢垂直拉力的有效性和可靠性。J Strength Cond Res 38(11): e670-e677, 2024-本研究考察了干板功率拍击测试（PS）作为评估上肢拉力的工具，以预测女性水球运动员的功能表现和竞技经验的有效性和可靠性。从国家队和发展队中招募了17名女性水球运动员。受试者完成了两次PS测试，并进行了一次功能表现测试，包括仅用臂力量完成的15米冲刺（15 mAOS）以及最大射门速度的5米测试（5 mMSV）。所有PS、15mAOS和5mMSV的结果进行了比较以评估其预测性。功率拍击得分在左侧PS（组内相关系数[ICC]：0.96，90%置信区间[CI]：0.91-0.98）、右侧PS（ICC：0.96, 90% CI: 0.90-0.98）、左和右质心位移(COM) (ICC：0.98，90% CI：0.96-0.99；ICC：0.95，90% CI：0.88-0.98）以及总PS（ICC：0.96, 90% CI: 0.92-0.99)上表现出高可靠性。所有绝对PS得分和左质心位移(COM disp L)与15 mAOS时间有较大的相关性（r = -0.542 至 -0.52，r² = 0.27-0.29, p 0.05）。本研究验证了PS作为上肢拉力干陆评估工具的可靠性。仅绝对PS得分和质心位移被确认为15米臂力量冲刺时间的弱预测因子。当将其与射门表现结合考虑时，其预测能力显著提高。所有绝对和归一化的动量和运动学PS参数无法预测功能表现和竞技经验。
