The popularity of rock climbing has resulted in a growing research base for the sport. However, at present there is a lack of sport-specific measures of performance in the field. The aim of this study was to examine the use of the powerslap test as a sport specific power measure.
The participants in this study were categorised into four different ability groups (novice, intermediate, advanced and elite) based on self reported lead grade. Two separate experiments were conducted to determine validity and reliability. The powerslap test was conducted on a revolution board with two variations - wide and narrow grip, for both sides of the body. The test started with the climber hanging at full extension from two holds from which a pull up movement was made releasing one hand to slap a scaled score board above.
There was a significant relationship between powerslap scores and climbing ability (Left Wide: r=0.7, P<0.0005; right wide: r=0.69, P<0.0005; left narrow: r=0.73, P<0.0005; right narrow: r =0.72, P<0.0005). Further to this, scores on the powerslap narrow test were significantly differentiated by climber ability (LEFT: F(3,37)=15.74, P<0.0005; right: F(3,37)=12.16, P<0.0005). Limits of agreement and intra-class correlation indicated that the powerslap test is a reliable performance measure.
According to the present findings the narrow grip variation of the powerslap test is a useful sport-specific power test that is related to climbing performance.
攀岩运动的普及促使该领域的研究基础不断扩大。然而,目前在该领域缺乏针对这项运动的特定表现衡量指标。本研究的目的是检验力量拍击测试作为一项针对该运动的特定力量衡量指标的适用性。
本研究的参与者根据自我报告的先锋攀登等级被分为四个不同能力组(新手、中级、高级和精英组)。进行了两项独立实验以确定有效性和可靠性。力量拍击测试在一个旋转板上进行,有两种变化形式——宽握和窄握,针对身体两侧。测试开始时,攀岩者从两个支撑点完全伸展悬挂,然后进行引体向上动作,松开一只手去拍打上方的计分板。
力量拍击测试得分与攀岩能力之间存在显著关系(左宽握:r = 0.7,P < 0.0005;右宽握:r = 0.69,P < 0.0005;左窄握:r = 0.73,P < 0.0005;右窄握:r = 0.72,P < 0.0005)。此外,力量拍击窄握测试的得分因攀岩者能力而有显著差异(左侧:F(3,37) = 15.74,P < 0.0005;右侧:F(3,37) = 12.16,P < 0.0005)。一致性界限和组内相关性表明力量拍击测试是一种可靠的表现衡量指标。
根据目前的研究结果,力量拍击测试的窄握变化形式是一项与攀岩表现相关的有用的针对该运动的特定力量测试。
