This pilot study, conducted in advance of a future definitive randomized controlled trial, aimed to investigate the feasibility of using a HIIT-based intervention to induce neurophysiological stress responses that could be associated with possible changes in mood. Twenty-five active male college students with an average age of 21.7 ± 2.1 years, weight 72.6 ± 8.4 kg, height 177 ± 6.1 cm, and BMI: 23.1 ± 1.4 kg/m took part in this quasi-experimental pilot study in which they were evaluated in two different sessions. In the first session, subjects performed a graded exercise test to determine the cycling power output corresponding to VO. The second session consisted of (a) pre-intervention assessment (collection of blood samples for measuring plasma corticotropin and cortisol levels, and application of POMS questionnaire to evaluate mood states); (b) exercise intervention (10 × 1-min of cycling at VO power output); (c) post-intervention assessment, and (d) 30-min post-intervention evaluation. Significant post-exercise increases in corticotropin and cortisol plasma levels were observed whereas mood states decreased significantly at this assessment time-point. However, a significant increase in mood was found 30-min after exercise. Finally, significant relationships between increases in stress hormones concentrations and changes in mood states after intense exercise were observed. In conclusion, our HIIT-based intervention was feasible to deliver and acceptable to participants. A single bout of HIIT induced acute changes in mood states that seems to be associated with hypothalamic-pituitary-adrenal axis activation.
这项初步研究旨在探讨使用高强度间歇训练（HIIT）干预来诱导神经生理应激反应的可行性，这种反应可能与情绪变化有关。该研究是一项未来确定性随机对照试验的前期研究，共有 25 名平均年龄为 21.7 ± 2.1 岁、体重 72.6 ± 8.4kg、身高 177 ± 6.1cm、BMI：23.1 ± 1.4kg/m²的活跃男性大学生参与了这项准实验性初步研究。在两次不同的评估中，参与者接受了评估。在第一次评估中，受试者进行了递增负荷运动测试，以确定与 VO 对应的自行车功率输出。第二次评估包括（a）干预前评估（采集血样以测量血浆促肾上腺皮质激素和皮质醇水平，并应用 POMS 问卷评估情绪状态）；（b）运动干预（10×1 分钟的自行车运动，功率输出为 VO）；（c）干预后评估，以及（d）干预后 30 分钟评估。结果发现，运动后血浆促肾上腺皮质激素和皮质醇水平显著升高，而此时的情绪状态显著下降。然而，运动后 30 分钟时发现情绪显著增加。最后，观察到应激激素浓度的增加与剧烈运动后情绪状态的变化之间存在显著关系。总之，我们的 HIIT 干预是可行的，且参与者可接受。单次 HIIT 可引起情绪状态的急性变化，这似乎与下丘脑-垂体-肾上腺轴的激活有关。
