目的：为了确定是否有一个适当的强度和持续时间的有氧条件锻炼的一个单一的会话有不同的急性影响的情绪nonexercisers比regularexercisers.Design：重复测量设计。设置：研究实验室。参与者：成年nonexercisers，适度的锻炼者，和ultramarathon跑步者（8名男性）。干预措施：在自行选择的速度下进行跑步机运动，以诱导13的感知消耗（RPE）等级（有点硬）20分钟，之前和之后是RPE为9的5分钟（非常轻）。主要结果测量：运动前和运动后5分钟的情绪状态概况。在超级马拉松运动员中，活力增加了8 +/- 7分（95%置信区间[CI]，5-12）的平均值+/-标准差，在中度运动者中增加了5 +/- 4分（95% CI，2-9），在非运动者中没有改善。疲劳下降5 6点（95% CI。2-8)中度运动者为4.4分（95%CI，1-7），非运动者无改善。运动后总情绪障碍平均减少21 +/- 16分（95% CI 12-29）在超级马拉松运动员中，16 +/- 10分（95% CI，7-24），中度运动者和9 +/- 13分（95%CI，1-18）。结论：一次适度的有氧运动可以提高经常锻炼者的活力，减少疲劳，但不会导致这些分数的变化。不锻炼的人尽管总的情绪障碍改善了锻炼者和非锻炼者的运动后，但经常锻炼者的效果大约是非锻炼者的两倍。这种有限的运动后情绪改善非锻炼者可能是一个重要的威慑坚持锻炼计划。
Objective: To determine whether a single session of exercise of appropriate intensity and duration for aerobic conditioning has a different acute effect on mood for nonexercisers than regular exercisers.Design: Repeated-measures design.Setting: Research laboratory.Participants: Adult nonexercisers, moderate exercisers, and ultramarathon runners (8 men. 8 women in each group).Interventions: Treadmill exercise at self-selected speeds to induce a rating of perceived exertion (RPE) of 13 (somewhat hard) for 20 minutes, preceded and followed by 5 minutes at an RPE of 9 (very light).Main Outcome Measure: Profile of Mood States before and 5 minutes after exercise.Results: Vigor increased by a mean +/- standard deviation of 8 +/- 7 points (95% confidence interval [CI], 5-12) among the Ultramarathon runners and 5 +/- 4 points (95% Cl, 2-9) among the moderate exercisers, with no improvement among the nonexercisers. Fatigue decreased by 5 6 points (95% Cl. 2-8) for the ultramarathon runners and 4 4 points (95% CI, 1-7) for the moderate exercisers, with no improvement among the nonexercisers. Postexercise total mood disturbance decreased by a mean of 21 +/- 16 points (95% CI 12-29) among the ultramarathon runners, 16 +/- 10 points (95% CI, 7-24) among the moderate exercisers, and 9 +/- 13 points (95% Cl, 1-18) among the nonexercisers.Conclusions: A single session of moderate aerobic exercise improves vigor and decreases fatigue among regular exercisers but causes no change in these scores for nonexercisers. Although total mood disturbance improves postexercise in exercisers and nonexercisers, regular exercisers have approximately twice the effect as nonexercisers. This limited postexercise mood improvement among nonexercisers may be an important deterrent for persistence with an exercise program.
