Loss of hand strength is a predictor of mortality in aging populations. Despite reliance on the hands to participate in equestrian driving activity, no existing studies focus on associations of hand strength to athletic performance. Therefore, this study 1) established baseline handgrip of equestrian combined drivers in standing and task-specific positions, 2) determined endurance of task-specific handgrip, 3) compared handgrip strength to normative data, and 4) evaluated associations of handgrip and equestrian-specific variables. There were 51 combined drivers (9 males, 42 females) ages 21–78 who completed a survey, standing handgrip, and grip strength and endurance in a task-specific position. Sixty-three percent of participants were 50 years or older. The dynamometer grip bar was normalized by hand size for standing tests; to duplicate sport-specific tasks, the bar was set to the closest setting. Significances were determined at p < 0.05. Drivers with more than 30 years of experience demonstrated highest summed standing (73.1 ± 5.2 kg) and summed sitting (59.9 ± 6.3 kg) grip strength. Females 60-years and older had greater handgrip endurance (Χ2 = 8.323, df = 2, p = .0156) in non-dominant (left) hands. Males (60%) reported more cold weather fatigue than females. Glove wearing was associated with bilateral endurance balance; a higher proportion of endurance balance between dominant and non-dominant (49% high-high and 29% low-low; Χ2 = 11.047, df = 1, p = .0009) was realized. There were no associations of handgrip and prior injury. Our results have implications in understanding task-specific and normative grip strengths in aging equestrian populations. Bilateral balance in handgrip strength and endurance is important particularly in maintaining strength in non-dominant hands over time. Equestrian driving sport promotes greater endurance in older females. Strength can be improved by participating in combined driving, and engagement in this sport over several years’ benefits hand strength over time. This cohort of equestrian participants provides evidence that participating in hand-specific activities promotes greater strength, which has been previously shown to improve aging outcomes.

组合驾驶：特定任务的位置影响马术运动员的握力

手部力量的丧失是老龄化人口死亡率的预测指标。尽管依靠手参与马术驾驶活动，但现有的研究没有关注手部力量与运动表现的关联。因此，本研究 1) 建立了马术组合驾驶员在站立和特定任务位置的基准手柄，2) 确定了特定任务手柄的耐力，3) 将手柄强度与规范数据进行了比较，以及 4) 评估了手柄和马术-具体变量。共有 51 名年龄在 21 至 78 岁之间的综合驾驶员（9 名男性，42 名女性）完成了一项调查，包括站立握力、握力和耐力在特定任务的位置。63% 的参与者年龄在 50 岁或以上。测力计握杆通过站立测试的手尺寸标准化；为了复制特定于运动的任务，该栏被设置为最接近的设置。显着性在 p < 0.05 时确定。拥有超过 30 年经验的车手表现出最高的站立握力（73.1 ± 5.2 公斤）和坐姿握力总和（59.9 ± 6.3 公斤）。60 岁及以上的女性在非惯用手（左手）中握持耐力更强（Χ2 = 8.323，df = 2，p = .0156）。男性（60%）报告的寒冷天气疲劳比女性多。戴手套与双边耐力平衡有关；实现了主导和非主导之间更高比例的耐力平衡（49% 高高和 29% 低-低；Χ2 = 11.047，df = 1，p = .0009）。握力和先前受伤没有关联。我们的研究结果对理解老龄化马术人口中特定任务和规范的握力有影响。握力和耐力的双边平衡对于长期保持非惯用手的力量尤为重要。马术驾驶运动可以提高老年女性的耐力。通过参加联合驾驶可以提高力量，并且多年来参与这项运动会随着时间的推移而受益于手部力量。这组马术参与者提供的证据表明，参加手部特定的活动可以促进更大的力量，这在以前已被证明可以改善衰老结果。多年参与这项运动会随着时间的推移而增强手部力量。这组马术参与者提供的证据表明，参加手部特定的活动可以促进更大的力量，这在以前已被证明可以改善衰老结果。多年参与这项运动会随着时间的推移而增强手部力量。这组马术参与者提供的证据表明，参加手部特定的活动可以促进更大的力量，这在以前已被证明可以改善衰老结果。
