44 formerly sedentary men (n=22) and women (n=22) self-selected cardiovascular exercise intensities, durations, and frequencies for 12 wk. A mean of approximately 2 exercise sessions/week, for 28 to 29 min./session were completed, and small (ds=.30 to .35) but significant (p<.05) cardiorespiratory (VO2 max) improvements were found. Reductions in Depression and Tension scores on the Profile of Mood States were also significant (ps<.05) over the 12 wk. No sex differences were found for change on any of the variables of interest. Analysis showed no significant correlations between change on either Depression and Tension scores, and change in VO2 max, over the 12 wk. Limitations and the need for replication with a control group were discussed. The possible advantages of allowing new and returning exercisers to self-select initial physical activity amounts were discussed.
44名曾久坐不动的男性（n = 22）和女性（n = 22）自行选择了为期12周的心血管运动强度、时长和频率。平均每周约进行2次锻炼，每次锻炼28至29分钟，结果发现心肺功能（最大摄氧量）有小幅（效应量d = 0.30至0.35）但显著（p < 0.05）的改善。在12周期间，情绪状态剖面图中的抑郁和紧张得分也有显著降低（p < 0.05）。在所关注的任何变量变化方面均未发现性别差异。分析表明，在这12周期间，抑郁和紧张得分的变化与最大摄氧量的变化之间均无显著相关性。文中讨论了研究的局限性以及设立对照组进行重复研究的必要性。还讨论了允许新的和恢复锻炼的人自行选择初始身体活动量可能带来的好处。
