The aim of this study was to examine whether lung function and respiratory muscle strength are associated with weightlifting strength and body composition in non-athletic males. A total 51 males with resistance training experience participated. One-repetition maximum tests were performed for the bench press, squat and deadlift and body composition was assessed. Lung function was evaluated with a pulmonary testing system and respiratory muscle strength was assessed with a handheld mouth-pressure manometer. Moderate to strong positive relationships were found between all weightlifting strength variables and maximal expiratory pressure (r = 0.36-0.54, p = ≤0.01). Small to strong positive correlations were found between fat-free mass, appendicular lean mass and most lung function variables (r = 0.29-0.54, p ≤ 0.039). However, fat-free mass and appendicular lean mass indexes were only related with respiratory muscle strength and not lung function. Expiratory muscle strength appears to influence weightlifting performance. Special exercises targeting the expiratory muscles may assist with improving weightlifting performance, especially for squats and deadlifts.
本研究旨在探讨非运动员男性的肺功能和呼吸肌力量与举重力量和身体成分的关系。共有 51 名有抗阻训练经验的男性参与。进行了卧推、深蹲和硬拉的一次重复最大测试，并评估了身体成分。使用肺测试系统评估肺功能，使用手持式口腔压力血压计评估呼吸肌力量。所有举重力量变量与最大呼气压力之间存在中度至强正相关（r=0.36-0.54，p=≤0.01）。瘦体重、四肢瘦体重与大多数肺功能变量之间存在小到强的正相关关系（r=0.29-0.54，p≤0.039）。然而，瘦体重和四肢瘦体重指数仅与呼吸肌力量相关，而与肺功能无关。呼气肌力量似乎会影响举重表现。针对呼气肌的特殊练习可能有助于提高举重表现，尤其是深蹲和硬拉。
