To investigate the inflammatory and perceptual responses to three different forms of upper-body exercise.
Twelve recreationally active, able-bodied males performed three work-matched arm-crank sessions in a randomised order: 30 min moderate-intensity continuous (CON), 30 min moderate-intensity with changes in cadence (CAD) and 20 min high-intensity interval training (HIIT). Blood samples were taken pre, post and 2-h post-exercise to determine plasma concentrations of interleukin (IL)-6 and IL-1ra. Perceptual responses pre, during and following the trials were assessed using the Feeling Scale, Felt Arousal Scale, Ratings of Perceived Exertion (RPE) and the Physical Activity Enjoyment Scale (PACES).
All trials were evenly effective in inducing an acute inflammatory response, indicated by similar increases in IL-6 after exercise and in IL-1ra at 2-h post exercise for all trials. More negative affect and higher RPE were reported during HIIT compared to CON and CAD, whereas PACES scores reported after exercise were higher for HIIT and CAD compared to CON.
When matched for external work, there was no difference in the inflammatory response to HIIT compared to moderate-intensity upper-body exercise. Although HIIT was (perceived as) more strenuous and affective responses were more negative during this mode, the higher ratings of enjoyment for both HIIT and CAD reported after exercise suggest that the inclusion of variation enhances enjoyment in upper-body exercise. As the fashion in which upper-body exercise is performed does not seem to influence the inflammatory response, it might be advised to prescribe varied exercise to enhance its enjoyment.
研究对三种不同形式的上身运动的炎症反应和感知反应。
12名有休闲运动习惯的健康男性以随机顺序进行了三次工作负荷匹配的手摇曲柄运动试验：30分钟中等强度持续运动（CON）、30分钟中等强度且节奏变化的运动（CAD）和20分钟高强度间歇训练（HIIT）。在运动前、运动后和运动后2小时采集血样，以测定血浆白细胞介素（IL）-6和IL-1ra的浓度。在试验前、试验期间和试验后，使用感觉量表、感觉唤醒量表、主观用力程度分级（RPE）和身体活动愉悦量表（PACES）评估感知反应。
所有试验在引发急性炎症反应方面均具有相同效果，所有试验运动后IL-6的增加以及运动后2小时IL-1ra的增加均相似。与CON和CAD相比，HIIT期间报告的消极情绪更多，RPE更高，而与CON相比，HIIT和CAD运动后报告的PACES得分更高。
当外部工作负荷相匹配时，与中等强度上身运动相比，HIIT的炎症反应没有差异。尽管HIIT（被认为）更费力，且在此模式下情感反应更消极，但运动后HIIT和CAD报告的更高愉悦评分表明，加入变化因素可提高上身运动的愉悦感。由于上身运动的方式似乎不影响炎症反应，建议采用多样化的运动方式来提高其愉悦感。
