Fitness levels of American youth have shown a marked decline in the last decade, according to recent studies. To determine whether such a tendency persists for entering college students, the authors evaluated 115 male and 143 female students for performance on the following fitness-related variables: (1) maximal oxygen consumption (estimated from Astrand cycling protocol), (2) body composition (skin-fold techniques), (3) muscle endurance (sit-up protocol), (4) muscle strength (bench-press protocol), and (5) joint flexibility (upper and lower body protocols). Although neither men nor women exhibited high levels of cardiorespiratory fitness, the women in the study showed higher relative levels than their male counterparts. Both groups showed excellent levels of muscle strength (compared with normative standards), but they achieved only an average standard for muscle endurance. Findings of relatively low levels of cardiovascular fitness compared with levels of muscle strength, particularly in men, seem to be a reflection of an inappropriate concentration of physical activity.
最近的研究表明,在过去十年中,美国青少年的健康水平显著下降。为了确定这种趋势是否在即将进入大学的学生中持续存在,作者评估了115名男学生和143名女学生在以下与健康相关变量上的表现:(1)最大耗氧量(根据阿斯兰德自行车运动方案估算),(2)身体成分(皮褶测量技术),(3)肌肉耐力(仰卧起坐方案),(4)肌肉力量(卧推方案),以及(5)关节灵活性(上半身和下半身方案)。尽管男性和女性都没有表现出高水平的心肺健康,但研究中的女性相对水平高于男性。两组的肌肉力量水平都很高(与标准水平相比),但肌肉耐力仅达到平均标准。与肌肉力量水平相比,心血管健康水平相对较低的结果,尤其是在男性中,似乎反映了体育活动的不合理集中。
