A 25-year population-based study was conducted to determine how physical fitness and participation in leisure-time physical activity in adolescence (age 12-18 years) predict leisure-time physical activity in adulthood (age 37-43 years). In 1976, five field tests were conducted to measure muscular fitness, agility and aerobic capacity, and self-report weekly frequencies of activity were obtained by questionnaire. A modified questionnaire was repeated in 2001, when participants were age 37-43 years (N = 1525). On the basis of the questionnaire, a physical activity index was calculated both in 1976 and 2001. The odds ratios (OR) for being inactive in adulthood among those who were physically very active in adolescence compared with those who were inactive in adolescence was 0.13 for males (95%CI: 0.06-0.31) and 0.28 for females (95%CI: 0.13-0.59). The odds ratio for adult inactivity among males in the highest versus lowest fitness group in adolescence was 0.24 (95%CI: 0.07-0.81). Activity in adolescence predicted activity in adulthood in both males and females. The risk for adult inactivity was significantly lower for those who were physically active in adolescence. In addition, high fitness predicted adult activity among males but not among females.
一项为期 25 年的基于人群的研究旨在确定青少年时期（12-18 岁）的体能和休闲时间体育活动参与度如何预测成年期（37-43 岁）的休闲时间体育活动。1976 年，进行了五项现场测试以测量肌肉力量、敏捷性和有氧能力，并通过问卷获得了自我报告的每周活动频率。2001 年，当参与者年龄在 37-43 岁时（N=1525），重复了一份经过修改的问卷。基于问卷，在 1976 年和 2001 年计算了一个体育活动指数。与青少年时期不活跃的人相比，青少年时期非常活跃的男性（95%CI：0.06-0.31）和女性（95%CI：0.13-0.59）在成年期不活跃的几率分别为 0.13 和 0.28。在青少年时期，最高与最低体能组中男性的成年不活跃几率比为 0.24（95%CI：0.07-0.81）。在男性和女性中，青少年时期的活动都预示着成年时期的活动。与青少年时期活跃的人相比，成年不活跃的风险明显降低。此外，高体能预测男性的成年活动，但不预测女性的成年活动。
