Relation between hand grip strength,respiratory muscle strength and spirometric measures in male nursing home residents

Abstract

Adverse-outcomes related to sarcopenia are mostly mentioned as physical disability. As the other skeletal muscles, respiratory muscles may also be affected by sarcopenia. Respiratory muscle strength is known to affect pulmonary functions. Therefore, we aimed to investigate the relations between extremity muscle strength, respiratory muscle strengths and spirometric measures in a group of male nursing home residents. Among a total of 104 male residents, residents with obstructive measures were excluded and final study population was composed of 62 residents. Mean age was 70.5?±?6.7 years, body mass index: 27.7?±?5.3?kg/m² and dominant hand grip strength: 29.7?±?6.5?kg. Hand grip strength was positively correlated with maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (r?=?0.35, p?<?0.01 and r?=?0.26, p?<?0.05, respectively). In regression analysis, the only factor related to MIP was hand grip strength; among spirometric measures only parameter significantly related to grip strength was peak cough flow (PCF). The association of PCF with grip strength disappeared when MIP alone or “MIP and MEP” were included in the regression analysis. In the latter case, PCF was significantly associated only with MIP. We found peripheric muscle strength be associated with MIP and PCF but not with MEP or any other spirometric parameters. The relation between peripheral muscle strength and PCF was mediated by MIP. Our findings suggest that sarcopenia may affect inspiratory muscle strength earlier or more than the expiratory muscle strength. Sarcopenia may cause decrease in PCF in the elderly, which may stand for some common adverse respiratory complications.

力量素质对幼儿园韵律活动下肢屈伸动作的影响

幼儿园韵律课程对幼儿的整体教育发展、幼儿音乐感知能力、艺术欣赏能力、动作运动能力等都有很大的帮助。本研究 从幼儿下肢的屈伸动作出发，以福州某幼儿园4-6 岁幼儿113 人（5 人未完成）为研究对象，通过对股四头肌、腘绳肌的能力训 练（训练步骤、强度、量等由幼儿舞蹈教学领域的专家5 名采用专家论证法），探究股四头肌、腘绳肌对幼儿韵律课程中的膝关 节屈伸动作的影响，发现股四头肌、腘绳肌的力量练习对幼儿园的韵律活动有一定的研究意义。
