Despite numerous studies providing evidence for positive effects of physical activity and physical fitness, evidence for association between physical fitness and health-related quality of life (HRQoL) in young adults is limited. The aim of the present cross-sectional study was to investigate the association of cardiorespiratory and muscular fitness with HRQoL from the perspective of its physical and mental components among young adult Finnish males.
The sample consisted of 754 men, with the mean age of 26 years (SD 6.7 years), who participated in the military refresher training. HRQoL was measured using the Finnish RAND 36-item health survey. Cardiorespiratory fitness was determined by a bicycle ergometer test, and muscular fitness by various tests measuring maximal strength and muscular endurance. Logistic regression modelling was used to compare low, moderate and high physical and mental component of HRQoL scores to the respective levels of muscular and cardiorespiratory fitness.
The findings of the adjusted (age, educational level, marital status, employment status, smoking, use of alcohol and BMI) analysis showed that cardiorespiratory and muscular fitness are positively associated with both physical and mental components of HRQoL. In terms of the physical component of HRQoL, even a moderate fitness level was positively associated with better HRQoL. In terms of the mental component of HRQoL, the impact was seen only in the group with the highest fitness level.
The findings suggest a positive contribution of physical fitness to mental health and highlight the importance of both muscular and cardiorespiratory fitness in the promotion of HRQoL. Even lighter forms of physical activity that result in moderate physical fitness could contribute to the physical component of HRQoL. In terms of the mental component of HRQoL, higher levels of physical fitness may be needed to gain higher levels of HRQoL among young males.
尽管有大量研究提供了身体活动和身体素质对健康有益的证据，但身体活动与年轻人健康相关生活质量（HRQoL）之间的关联证据有限。本横断面研究的目的是从身体和心理两个方面探讨年轻芬兰男性的心肺和肌肉健康与 HRQoL 之间的关系。
该样本包括 754 名年龄为 26 岁（标准差为 6.7 岁）的男性，他们参加了军事再培训。使用芬兰 RAND 36 项健康调查来测量 HRQoL。心肺功能是通过自行车测功计测试确定的，肌肉健康是通过各种测试来衡量最大力量和肌肉耐力的。使用逻辑回归模型将低、中、高身体和心理成分 HRQoL 评分与相应的肌肉和心肺健康水平进行比较。
调整（年龄、教育水平、婚姻状况、就业状况、吸烟、饮酒和 BMI）分析的结果表明，心肺和肌肉健康与 HRQoL 的身体和心理成分都呈正相关。就 HRQoL 的身体成分而言，即使是中等水平的健康状况也与更好的 HRQoL 呈正相关。就 HRQoL 的心理成分而言，这种影响仅在健康水平最高的组中可见。
研究结果表明，身体素质对心理健康有积极的贡献，并强调了肌肉和心肺健康在促进 HRQoL 方面的重要性。即使是导致中等健康水平的较轻形式的身体活动也可能有助于 HRQoL 的身体成分。就 HRQoL 的心理成分而言，年轻人可能需要更高水平的身体素质才能获得更高水平的 HRQoL。
