摘要
目的:分析腕部缠绕对最大握力和动态阻力值的影响。方法:采用对照随机交叉试验，将54名Crossfit参与者随机分为两组。第1组从控制性包裹开始，第2组从功能性包裹开始。交替进行了4次动态抓握强度抗力试验，并计算了阻力值和疲劳值。结果:从握力测试中获得的值没有显示手腕包裹对最大握力的增加有任何影响(35.7 vs 35.6 kg;P =0.737)或更大的耐力(78.2 vs 77.8%;p = 0.549)。两组的疲劳程度相同(组间平均差异:0.1 kg, CI= -0.7-0.8;p = 0.779)。结论:使用腕带增加最大力量和动态握力耐力的假设在本研究中被拒绝。证据等级I;随机对照试验。
EFFECT OF WRIST WRAP IN HANDGRIP STRENGTH IN CROSSFIT.
Objectives: Analyze wrist wrap influence on the values of maximum handgrip strength and dynamic resistance.
Methods: A controlled randomized cross-over trial including 54 Crossfit participants randomly assigned to two groups. Group 1 began the series of tests with control wrapping, and Group 2 started with functional wrapping. Alternate series of four dynamic grip strength resistance tests were performed, and the resistance and fatigue values were calculated.
Results: The values obtained from the grip tests did not indicate any effect from the wrist wrap for an increase in maximum grip strength (35.7 vs. 35.6 kg; p=0.737) or greater endurance (78.2 vs. 77.8%; p=0.549). Fatigue was also equal in both groups (mean differences between the groups: 0.1 kg, CI= -0.7-0.8; p=0.779).
Conclusion: The hypothesis that using a wrist wrap increases maximum strength and dynamic handgrip endurance was rejected in this study. Evidence Level I; Randomized control trial .
