EXTREME CONDITIONING TRAINING: ACUTE EFFECTS ON MOOD STATE

ABSTRACT Introduction: The search for strategies aimed at reducing daily stress is increasing in the current literature. As a result, several types of fitness training are constantly being investigated for their influence on mood states. However, we know little about strategies that use higher intensities. Objective: To investigate the acute effects of an extreme conditioning training (ECT) session on the mood states of individuals with or without prior experience in this type of training. Methods: Volunteers were divided into TRAINED (n = 10) and CONDITIONED (n = 10) groups, undergoing a single 9-minute ECT session. Mood states (BRUMS scale) were analyzed at baseline, immediately afterwards, and after 30 minutes. Results: Anger, confusion and tension were significantly reduced in both groups immediately afterwards and post 30 minutes. The TRAINED group showed a significant reduction in fatigue 30 minutes after the end of the session. Effect size for all variables was considered small to moderate. The TRAINED group had significantly increased vigor immediately after the end of the session compared to baseline. However, the CONDITIONED group had significantly reduced vigor 30 minutes afterwards, in comparison to baseline. The increase in vigor in the TRAINED group was considered moderate (ES = 0.68), while the decrease in vigor in the CONDITIONED group was considered major (ES = −0.88). Conclusion: An ECT session is powerful enough to induce significant, albeit small and moderate, changes in mood states in both trained and untrained individuals in this particular type of exercise.

摘要
当前学界针对缓解日常压力的策略研究愈发增多，诸多健身训练方式对情绪状态的影响正被持续探究，但针对高强度训练策略的相关研究仍较为匮乏。
研究目的：探究极端负荷训练（Extreme Conditioning Training, ECT）单次课程对有或无该类训练经验个体情绪状态的急性影响。
研究方法：将志愿者分为训练组（TRAINED，n=10）与未训练组（CONDITIONED，n=10），两组均接受单次时长9分钟的极端负荷训练课程。分别于基线水平、训练结束即刻及训练后30分钟，采用BRUMS情绪量表对受试者的情绪状态进行分析评定。
研究结果：两组受试者在训练结束即刻及训练后30分钟时，愤怒、困惑与紧张情绪均显著降低。训练组在训练结束30分钟后，疲劳感出现显著缓解。所有观测变量的效应量均处于小至中等水平。训练组在训练结束即刻的活力水平较基线显著提升；而未训练组在训练后30分钟时，活力水平较基线出现显著下降。训练组的活力提升效应量为中等（ES=0.68），未训练组的活力下降效应量则为较大（ES=−0.88）。
研究结论：单次极端负荷训练课程即可对有该类训练经验与无经验个体的情绪状态产生显著影响，尽管此类影响仅处于小至中等程度。证据等级：Ⅱ级，治疗性研究——治疗效果探究。
