OBJECTIVE
To investigate the effects of high- and low-load supervised, volume-matched resistance training (RT) on body composition, muscle function, and functional capacity in older adults with prediabetes.
METHODS
Older adults with prediabetes were recruited and randomly assigned to high-load RT (n = 13), low-load RT (n = 12), or control groups (n = 12).
RESULTS
No significant differences were observed in body composition at postintervention. High-load and low-load RT groups exhibited significant improvements in functional tests at postintervention compared with the control group. The high-load RT group exhibited a greater improvement in muscle strength and muscle quality at postintervention compared with the low-load RT group.
CONCLUSION
Supervised RT is useful in the prevention of muscle functional loss in older adults with prediabetes. High-load RT is superior for enhancing muscle strength and muscle quality, despite a similar increase in functional capacity.
目的
探讨高负荷和低负荷监督下、容量匹配的阻力训练（RT）对糖尿病前期老年人身体成分、肌肉功能和功能能力的影响。
方法
招募糖尿病前期老年人，并将其随机分为高负荷RT组（n = 13）、低负荷RT组（n = 12）或对照组（n = 12）。
结果
干预后身体成分未观察到显著差异。与对照组相比，高负荷和低负荷RT组在干预后功能测试中表现出显著改善。与低负荷RT组相比，高负荷RT组在干预后肌肉力量和肌肉质量有更大改善。
结论
监督下的RT对预防糖尿病前期老年人肌肉功能丧失有用。尽管功能能力有类似增加，但高负荷RT在增强肌肉力量和肌肉质量方面更具优势。
