Abstract

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.

垂直跳跃高度和握力测量中与年龄有关的差异。
目的:本研究旨在探讨年龄对女性垂直跳跃高度和握力测量的影响。另一个目的是研究垂直跳跃高度和握力之间的相关性:二十名年轻(21.5±2.8 岁)和二十名年长(67.0±5.5 岁)的健康女性参加了此次研究。手握收缩用于评估不同时间间隔的峰值力量和力量发展速度。垂直跳跃在跳垫上进行。结果:结果:老年妇女的垂直跳跃高度(P < 0.001)、手握峰值力(P = 0.028)和力量发展速度值(P = 0.003-0.016)均低于年轻妇女。与手握峰值力和力量发展率(12%-17%)相比,在垂直跳跃高度(41%)方面观察到的组间差异更大。在所有力量测量中,年轻女性(r = 0.502,P = 0.024)和年长女性(r = 0.446,P = 0.049)在 200 毫秒时的手握力发展率与垂直跳跃高度的相关性最强:本次调查显示,与年轻女性相比,老年女性的垂直跳跃高度、手握峰值力量和力量发展速度值明显较低。有趣的是,年龄组之间在跳高高度上的差异要大于手握峰值力和力量发展率。这表明,垂直跳跃成绩受年龄的影响可能比手握力量特征更严重。
