The facilitative effect of physical activity on age-related decline is well documented. Specifically, it has been found to reduce the risk of dependency. However, physical activity programs for older adults should be carefully designed so that improvements in all aspects of movement and physical capacities are achieved. This means that efficient fitness measurements should be made available for coaches and trainers. The arm-curl test is a common field test known for measuring the strength of upper extremities in older age. The objective of the current study was to determine to what extent this test indeed assesses arm strength as well as other fitness aspects such as arm muscle endurance or general endurance. Scores of the arm-curl test were compared with strength and endurance of elbow flexors measured by an isokinetic dynamometer and general endurance measured by a stress test in 48 independently functioning women (age 72.04 ± 6.28 yr). Significant correlations were indicated between the arm-curl scores and both isokinetic endurance (r = 0.452) and general endurance (r = 0.437); however, a very low nonsignificant correlation was found between the arm-curl and isokinetic maximal strength scores. Coaches must be aware of the fact that the repetitive arm-curl exercise contains a significant aerobic component and thus may contribute to aerobic fitness and arm muscle endurance but not necessarily to arm strength.
体力活动对与年龄相关的衰退的促进作用已有充分记录。具体来说，它已被发现可降低依赖的风险。然而，应为老年人精心设计体力活动计划，以实现运动和身体能力各个方面的改善。这意味着教练和培训师应该能够获得有效的健身测量方法。手臂卷曲测试是一种常见的现场测试，用于测量老年人上肢的力量。本研究的目的是确定该测试在多大程度上确实评估了手臂力量以及其他健身方面，如手臂肌肉耐力或一般耐力。手臂卷曲测试的分数与通过等速测力计测量的肘部屈肌的力量和耐力以及通过应激测试测量的一般耐力进行了比较，共涉及 48 名独立功能的女性（年龄 72.04 ± 6.28 岁）。手臂卷曲分数与等速耐力（r = 0.452）和一般耐力（r = 0.437）之间均呈显著相关；然而，手臂卷曲和等速最大力量分数之间的相关性非常低且无统计学意义。教练必须意识到，重复的手臂卷曲运动包含重要的有氧运动成分，因此可能有助于有氧健身和手臂肌肉耐力，但不一定有助于手臂力量。
