The association of physical activity with coronary risk factors and self-reported physical ability was studied in a cohort of 331 healthy Finnish men aged 45-64 years at entry, representing the survivors of a 20-year longitudinal study from 1964 to 1984. Baseline physical activity was not significantly related to levels of coronary risk factors at subsequent 5-year, 10-year or 20-year follow-up examinations. The 72 who increased their physical activity during the study period smoked less at 20-year follow-up than those who remained sedentary (p = 0.03). No other significant associations between 20-year changes of physical activity and coronary risk factors were seen. Although baseline physical activity was not, physical activity and exercise at 20-year follow-up were positively related to indices of functional capacity assessed at the end of the study period, when the subjects had reached a mean age of 73 years. It is concluded from this long-term study that a relative increase of physical activity between middle and old age is associated with both less smoking and a maintained high level of physical ability.
在一个由331名45 - 64岁健康芬兰男性组成的队列中，研究了体力活动与冠心病危险因素以及自我报告的身体能力之间的关联。这些男性是1964年至1984年一项20年纵向研究的幸存者。在随后的5年、10年或20年随访检查中，基线体力活动与冠心病危险因素水平无显著相关性。在研究期间增加体力活动的72人在20年随访时的吸烟量比那些保持久坐的人少（p = 0.03）。在体力活动的20年变化与冠心病危险因素之间未发现其他显著关联。尽管基线体力活动与冠心病危险因素无关，但在研究期末，当受试者平均年龄达到73岁时，20年随访时的体力活动和锻炼与功能能力指标呈正相关。从这项长期研究得出的结论是，从中年到老年体力活动的相对增加与较少吸烟以及保持较高的身体能力水平有关。
