研究发现,较强壮的老年妇女寿命更长。 Stronger older women live longer, study finds.

2026年2月在JAMA Network Open出版的一份新研究报告发现,63-99岁的妇女,即使考虑到年龄、健康、有氧健身和生活方式因素,其肌肉强度也与较长的寿命有关。 A new study published in February 2026 in JAMA Network Open finds that greater muscular strength is linked to longer lifespans in women aged 63 to 99, even after accounting for age, health, aerobic fitness, and lifestyle factors. 研究人员利用握力和5次坐视测试,分析了妇女保健倡议中的5 472名妇女的数据。 Using grip strength and the 5-times-sit-to-stand test, researchers analyzed data from 5,472 women in the Women’s Health Initiative. 在为期八年的后续行动中,三分之一以上的妇女死亡,但较强大的妇女过早死亡的风险要低得多——至少减少三分之一。 Over an eight-year follow-up, more than a third died, but stronger women had a significantly lower risk of early death—reducing it by at least a third. 结果表明,肌肉力量独立地有助于长寿,突出了体力培训是健康老龄化的关键因素。 The results suggest muscular strength independently contributes to longevity, highlighting strength training as a key factor in healthy aging.
