摘要

背景:除了与老年人身体虚弱和功能残疾的发病机制有关外，肌肉无力还与负面结果相关。肌肉力量和功能被认为是衰老的生物标志物。渐进式阻力训练(PRT)是一种一直被研究的训练类型，因为它作为一种治疗选择，可以对抗老年人肌肉力量和功能的减少。然而，很少有研究评估PRT后老年人肌肉力量和功能水平的临床相关收益，此外还需要测试新的PRT方法，包括训练计划的个体化和分期。因此，本文旨在评估个体和周期PRT方案对老年人握力和功能的影响。因此，研究样本包括69名老年人，分为两组:病例组(n = 41)和对照组(n = 28)。病例组参加了为期12周的渐进式阻力训练方案，每周两次。与只接受健康教育的对照组相比，病例组的个体在与评估功能相关的所有变量(计时和行走测试、步态速度和握力)上都有更大程度的改善，证明了评估方案在改善社区老年人力量和功能方面的适用性。

THE EFFECT OF PROGRESSIVE RESISTANCE TRAINING ON FUNCTIONALITY AND HANDGRIP STRENGTH IN THE OLDER INDIVIDUALS OF A COMMUNITY: A QUASI-EXPERIMENTAL STUDY.

BACKGROUND Muscle weakness is associated with negative outcomes, in addition to being related to the pathogenesis of frailty and functional disability in the older individuals. Muscle strength and functionality are considered biomarkers of aging. Progressive resistance training (PRT) is a type of training that has been the subject of studies as it presents itself as a therapeutic option to fight the reduction of muscle strength and functionality in older individuals. However, few studies have assessed the clinically-relevant gains in the levels of muscle strength and functionality of older individuals after PRT, in addition to the need of testing new PRT approaches, including individualization and periodization in training programs. Therefore, this article aims to assess the effect of a individual and periodized PRT protocol on handgrip strength and functionality in older individuals. Thus, the study sample included 69 older individuals, divided into two groups: case (n = 41) and control (n = 28). The case group participated in a progressive resistance training protocol for 12 weeks, with two weekly sessions. When compared to the control group, which received only health education, the individuals in the case group had a greater magnitude of improvement in all variables related to the assessed functionality (Timed up and go test, gait speed, and handgrip strength), proving the applicability of the assessed protocol to improve strength and functionality in the older individuals people of a community.

期刊介绍： Rejuvenation Research publishes cutting-edge, peer-reviewed research on rejuvenation therapies in the laboratory and the clinic. The Journal focuses on key explorations and advances that may ultimately contribute to slowing or reversing the aging process, and covers topics such as cardiovascular aging, DNA damage and repair, cloning, and cell immortalization and senescence. Rejuvenation Research coverage includes: Cell immortalization and senescence Pluripotent stem cells DNA damage/repair Gene targeting, gene therapy, and genomics Growth factors and nutrient supply/sensing Immunosenescence Comparative biology of aging Tissue engineering Late-life pathologies (cardiovascular, neurodegenerative and others) Public policy and social context.
