The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) potential factors that may influence grip strength and (2) hypothesize strategies that may be able to influence grip strength and ultimately attain a higher baseline level of strength. Although there appears to be a limited ability to augment grip strength as an adult, there may be critical periods during growth/development during which individuals can establish a higher baseline. Establishing a high baseline of strength earlier in life may have long-term implications related to mortality and disease.
握力与死亡率之间的关系常被用来强调抗阻运动在身体活动指南中的重要性。然而，传统的抗阻训练似乎并不能显著改变握力。因此，握力可以被认为是与抗阻运动无关的力量的反映。如果这是真的，那么握力并不能告诉我们抗阻运动对成年人的重要性，而是可能突出了与较弱者相比，“基线”时更强壮的个体之间的内在差异。本文的目的是讨论：（1）可能影响握力的因素；（2）假设可能影响握力并最终达到更高基线力量水平的策略。尽管成年人增加握力的能力似乎有限，但在生长/发育过程中可能存在一些关键时期，个体可以在这些时期建立更高的基线。在生命早期建立较高的力量基线可能会对死亡率和疾病产生长期影响。
