There is a growing body of information supporting the beneficial effects of estrogen and estrogen-based hormone therapy (HT) on maintenance and enhancement of muscle mass, strength, and connective tissue. These effects are also evident in enhanced recovery from muscle atrophy or damage and have significant implications particularly for the muscular health of postmenopausal women. Evidence suggests that HT will also help maintain or increase muscle mass, improve postatrophy muscle recovery, and enhance muscle strength in aged females. This is important because this population, in particular, is at risk for a rapid onset of frailty. The potential benefits of estrogen and HT relative to skeletal muscle function and composition combined with other health-related enhancements associated with reduced risk of cardiovascular events, overall mortality, and metabolic dysfunction, as well as enhanced cognition and bone health cumulate in a strong argument for more widespread and prolonged consideration of HT if started proximal to menopausal onset in most women. Earlier reports of increased health risks with HT use in postmenopausal women has led to a decline in HT use. However, recent reevaluation regarding the health effects of HT indicates a general lack of risks and a number of significant health benefits of HT use when initiated at the onset of menopause. Although further research is still needed to fully delineate its mechanisms of action, the general use of HT by postmenopausal women, to enhance muscle mass and strength, as well as overall health, with initiation soon after the onset of menopause should be considered.
越来越多的信息支持雌激素和基于雌激素的激素疗法(HT)对维持和增强肌肉质量、力量和结缔组织的有益作用。这些作用在增强肌肉萎缩或损伤后的恢复方面也很明显,对绝经后妇女的肌肉健康具有重要意义。有证据表明,HT 还将有助于维持或增加肌肉质量,改善萎缩后肌肉的恢复,以及增强老年女性的肌肉力量。这很重要,因为特别是这个人群,很容易出现虚弱的快速发作。雌激素和 HT 相对于骨骼肌肉功能和组成的潜在益处,以及与心血管事件、总死亡率和代谢功能障碍风险降低相关的其他健康相关增强,以及认知和骨骼健康的增强,都强烈表明,如果大多数女性在绝经前开始,HT 的使用应该更广泛和更长期地考虑。早期关于 HT 在绝经后妇女中使用增加健康风险的报告导致 HT 使用减少。然而,最近对 HT 健康影响的重新评估表明,当 HT 在绝经开始时使用时,一般缺乏风险,并且有许多显著的健康益处。尽管仍需要进一步研究来充分阐明其作用机制,但应考虑绝经后妇女普遍使用 HT,以增强肌肉质量和力量以及整体健康,在绝经后不久开始使用。
