摘要

目的探讨年龄对女性垂直跳跃高度和握力测量的影响。第二个目的是调查垂直跳跃高度和握力之间的相关性。方法选取健康女性20例(21.5±2.8岁)和老年女性20例(67.0±5.5岁)。用握力收缩来评估不同时间间隔的峰值力和力发展速度的强度测量。垂直跳跃在跳台上进行,跳台根据飞行时间测量垂直跳跃高度。结果老年妇女垂直跳高较低(P <握力峰值值(P = 0.028)和力发展速率值(P = 0.003 ~ 0.016)均高于年轻女性。各组之间垂直跳跃高度(41%)的差异大于握力峰值和力发展率(12-17%)。在所有的力量测量中,年轻女性(r = 0.502, P = 0.024)和老年女性(r = 0.446, P = 0.049)在200 ms时的握力发展速率与垂直跳跃高度的相关性最强。结论与年轻女性相比,老年女性的垂直跳高、握力峰值和力发展速率值明显降低。有趣的是,年龄组间跳跃高度的差异大于握力峰值和力发展速度的差异。这表明垂直跳跃的表现可能更严重地受到年龄的影响,而不是握力特征。

Age-related differences in vertical jump height and handgrip strength measurements
Purpose This study aimed to examine the effects of age on vertical jump height and handgrip strength measurements in women. A secondary aim was to investigate the correlations between vertical jump height and handgrip strength. Methods Twenty young (21.5 ± 2.8 years) and twenty older (67.0 ± 5.5 years) healthy women participated in this study. Handgrip contractions were used to assess strength measurements of peak force and rate of force development at different time intervals. Vertical jumps were performed on a jump mat. The jump mat measured vertical jump height based on flight time. Results The older women had lower vertical jump height (P < 0.001) and handgrip peak force (P = 0.028) and rate of force development values (P = 0.003-0.016) than the younger women. A larger difference was observed between the groups for vertical jump height (41%) than handgrip peak force and rate of force development (12-17%). Of all the strength measurements, handgrip rate of force development at 200 ms in the young (r = 0.502, P = 0.024) and older (r = 0.446, P = 0.049) women exhibited the strongest correlation with vertical jump height. Conclusions This investigation showed significantly lower vertical jump height and handgrip peak force and rate of force development values in older compared to younger women. Interestingly, the difference between age groups was larger for jump height than handgrip peak force and rate of force development. This suggests that vertical jump performance may be more severely affected by age than handgrip strength characteristics.
