背景：年龄和性别对肌肉张力和力学性能的影响尚未使用手持肌力测量技术进行研究。目的：本研究旨在提供关于年龄和性别对股四头肌和二头肌肌肉张力和力学特性的影响的客观数据。方法：在123名健康男女(年龄18-90岁；61名18-35岁；62名65-90岁)的对比研究中，使用MyotonPRO仪器测量肌肉张力、弹性和僵直。0.001)。当结合男性和女性的数据时，在老年人中，BB的音调明显更大，而RF的音调则不明显(p=0.28)。BB在两个年龄组中均无性别差异。在RF中，男性有更大的僵硬(年轻男性292对女性233 N/m；老年男性328对女性311 N/m)和音调(年轻16.4对13.6赫兹；老年16.7对14.9赫兹)。青年男性RF的弹性低于女性，但在老年组之间无差异(男女对数值均减少1.6)。结论：随着年龄的增长，肌肉僵硬和张力增加，弹性降低。这些发现对使用一种新的生物标记物检测脆弱性具有重要意义。在评估病理条件对老年人肌肉特性的影响时，年龄和性别差异是重要的考虑因素。(C)2015爱思唯尔爱尔兰有限公司。保留所有权利。
Background: Age and gender effects on muscle tone and mechanical properties have not been studied using hand-held myometric technology. Monitoring changes in muscle properties with ageing in community settings may provide a valuable assessment tool for detecting those at risk of premature decline and sarcopenia.Objective: This study aimed to provide objective data on the effects of ageing and gender on muscle tone and mechanical properties of quadriceps (rectus femoris) and biceps brachii muscles.Methods: In a comparative study of 123 healthy males and females (aged 18-90 years; n = 61 aged 18-35; n = 62 aged 65-90) muscle tone, elasticity and stiffness were measured using the MyotonPRO device.Results: Stiffness was greater and elasticity lower in older adults for BB and RF (p < 0.001). Tone was significantly greater in older adults for BB but not for RF when data for males and females were combined (p = 0.28). There were no gender differences for BB in either age group. In RF, males had greater stiffness (young males 292 vs females 233 N/m; older males 328 vs females 311 N/m) and tone (young 16.4 vs 13.6 Hz; older 16.7 vs 14.9 Hz). Elasticity in RF was lower in young males than females but did not differ between the older groups (both males and females log decrement 1.6).Conclusions: Stiffness and tone increased with ageing and elasticity decreased. These findings have implications for detecting frailty using a novel biomarker. Age and gender differences are important to consider when assessing effects of pathological conditions on muscle properties in older people. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
