Abstract

Objectives

The purposes of this study were to analyze the effect of resistance training (RT) on depressive and anxiety symptomsand examine the possible consequences of age, cognitive alterations, and muscular strength on such symptoms.Method: Forty-one older women (68 ± 8 years) composed a training group (TG) or a control group (CG). The TG was submitted to a supervised, progressive RT program over 12 weeks, involving eight whole-body exercises performed with three sets of 8-12 repetitions, three days per week, whereas CG remains with no intervention for the same period. Muscular strength (one-repetition maximum tests), cognitive function (Montreal Cognitive Assessment - MoCA; Verbal Fluency Tests), depression (15-item eriatric Depression Scale - GDS-15), and anxiety (Beck Anxiety Inventory - BAI) were assessed before and after the intervention period.

Results

There were observed significant (P < 0.001) RT-induced improvements on total muscular strength (TG: pre = 122.4 ± 24.1/post = 134.3 ± 36.7; CG: pre = 105.4 ± 15.4/post = 99.2 ± 17.1) and MoCA (TG: pre =21.7 ± 4.5/post = 22.5 ± 4.7; CG: pre = 20.3 ± 3.7/post = 19.3 ± 4.1). Depressive and anxiety symptoms (even when adjusted by chronological age and changes in muscular strength or cognitive function) were reduced with RT according to GDS-15 (TG: pre = 2.26 ± 1.53/post = 1.92 ± 1.68; CG: pre =2.68 ± 1.13/post = 2.25 ± 1.18) and BAI (TG: pre = 4.07 ± 5.68/post = 2.33 ± 3.71; CG: pre = 5.18 ± 7.70/post = 9.81 ± 7.10). The time x group interactions were significant for depressive and anxiety symptoms.

Conclusions

Our results suggest that a 12-week RT program reduces depressive and anxiety symptoms, regardless of age, muscular strength, and cognition function in older women.

抗阻训练可减少老年女性的抑郁和焦虑症状：一项试点研究

摘要

目标

本研究的目的是分析阻力训练 (RT) 对抑郁和焦虑症状的影响，并检查年龄、认知改变和肌肉力量对这些症状的可能后果。方法：41 名老年女性（68 ± 8 岁）组成训练组（TG）或对照组（CG）。TG 接受了为期 12 周的有监督的渐进式 RT 计划，包括 8 次全身锻炼，每组 8-12 次重复，每周 3 天，而 CG 在同一时期保持没有干预。之前评估了肌肉力量（一次重复最大测试）、认知功能（蒙特利尔认知评估 - MoCA；语言流利度测试）、抑郁症（15 项 eritric Depression Scale - GDS-15）和焦虑症（Beck Anxiety Inventory - BAI）并且在干预期之后。

结果

观察到 RT 诱导的总肌肉力量显着改善（P < 0.001）（TG：pre = 122.4 ± 24.1/post = 134.3 ± 36.7；CG：pre = 105.4 ± 15.4/post = 99.2 ± 17.1）和 MoCA（TG ：前=21.7±4.5/后=22.5±4.7；CG：前=20.3±3.7/后=19.3±4.1）。根据 GDS-15（TG：pre = 2.26 ± 1.53/post = 1.92 ± 1.68；CG：pre =2.68 ± 1.13/post = 2.25 ± 1.18) 和 BAI (TG: pre = 4.07 ± 5.68/post = 2.33 ± 3.71; CG: pre = 5.18 ± 7.70/post = 9.81 ± 7.10)。时间 x 组交互对于抑郁和焦虑症状是显着的。

结论

我们的结果表明，无论年龄、肌肉力量和认知功能如何，12 周的放疗计划都能减少老年女性的抑郁和焦虑症状。
