目标。高运动强度可能会降低对运动计划的坚持，可能是因为它被认为是令人厌恶的。然而，一些作者建议，运动强度必须达到最大有氧能力 (VO2max) 的 60% 或 70%，才能引发积极的情感变化。为了阐明这种差异，我们检查了对运动强度增加的情感反应。设计。总计 30 名志愿者在跑步机上跑步时每分钟评估他们的影响，同时速度和等级逐渐增加。方法。该方法在三个方面是独特的：（1）根据回环模型的维度而不是不同的情感状态来评估情感，（2）在运动之前、期间和之后重复评估情感，而不仅仅是之前和之后，（3）根据代谢可比阶段（开始、通气阈值、最大摄氧量）而不是最大能力的百分比，对参与者的运动强度进行标准化。结果。运动前后的比较显示了情感上的益处，表现为增加能量唤醒和减少紧张唤醒。然而，在运动过程中，情感效价恶化到超过通气阈值，直到最大摄氧量，这一趋势在冷却过程中立即逆转。结论。需要过渡到无氧代谢的运动强度可能会对情绪产生短暂但实质性的负面影响，进而可能会降低对运动计划的坚持。
Objectives. High exercise intensity may be associated with reduced adherence to exercise programmes, possibly because it is perceived as aversive. However, several authors have suggested that an intensity as high as 60% or 70% of maximal aerobic capacity (VO2max) is necessary for exercise to elicit positive affective changes. To elucidate this discrepancy, the affective responses to increasing levels of exercise intensity were examined.Design. In total, 30 volunteers rated their affect every minute as they ran on a treadmill while the speed and grade were progressively increased.Method. The methodology was unique in three respects: (1) affect was assessed in terms of the dimensions of the circumplex model instead of distinct affective states, (2) affect was assessed repeatedly before, during, and after exercise, not only before and after, and (3) exercise intensity was standardized across participants in terms of metabolically comparable phases (beginning, ventilatory threshold, VO2max) instead of percentages of maximal capacity.Results. Pre-to-post-exercise comparisons indicated affective benefits in the form of increased energetic arousal and decreased tense arousal. During exercise, however, affective valence deteriorated beyond the ventilatory threshold and until VO2max, a trend that reversed itself instantaneously during cool-down.Conclusions. Exercise intensity that requires a transition to anaerobic metabolism can have a transient but substantial negative impact on affect and this may, in turn, reduce adherence to exercise programmes.
