The inverse relationship between exercise intensity and affective valence is well established for continuous exercise but not for high-intensity interval exercise (HIIE). The objective was to verify the dose-response relationship between exercise intensity and affective valence in HIIE sessions. Eleven young men underwent a vigorous-intensity continuous exercise (VICE) and three HIIE sessions at the same average intensity (70% of peak power-W) and duration (20 min) but with different amplitudes: 10 × [1 min at 90% W/1 min at 50% W]-HIIE-90/50; 10 × [1 min at 100% W/1 min at 40% W]-HIIE-100/40; 10 × [1 min at 110% W/1 min at 30% W]-HIIE-110/30. During the exercise sessions, psychophysiological variables were recorded (VO, VCO, heart rate, perceived exertion CR10, and Feeling Scale (FS)). Higher correlations were found between CR10 and FS for all conditions (VICE = -0.987; HIIE-90/50 = -0.873; HIIE-100/40 = -0.908; HIIE-110/30 = -0.948). Regarding the physiological variables, the %HR presented moderate inverse correlations with FS for all exercise conditions (VICE = -0.867; HIIE-90/50 = -0.818; HIIE-100/40 = -0.837; HIIE-110/30 = -0.828) while the respiratory variables (%VO and %VCO) presented low-to-moderate correlations only for VICE, HIIE-90/50, and HIIE-100/40 (ranging from -0.523 to -0.805). Poor correlations were observed between the %VO (r = -0.293) and %VCO (r = -0.020) with FS. The results indicated that perceived exertion is more sensible than physiological variables to explain the intensity-affective valence relationship in HIIE sessions. RPE should be used for HIIE prescription with a focus on affect.
运动强度与情感效价之间的反比关系在连续运动中已得到充分证实，但在高强度间歇运动（HIIE）中并非如此。本研究旨在验证 HIIE 过程中运动强度与情感效价之间的剂量反应关系。11 名年轻男性分别进行剧烈强度的连续运动（VICE）和 3 次 HIIE 运动，平均强度（70%最大摄氧量-W）和持续时间（20 分钟）相同，但幅度不同：10×[1 分钟 90% W/1 分钟 50% W]-HIIE-90/50；10×[1 分钟 100% W/1 分钟 40% W]-HIIE-100/40；10×[1 分钟 110% W/1 分钟 30% W]-HIIE-110/30。在运动过程中，记录了心理生理变量（VO、VCO、心率、感觉用力等级 10（CR10）和感觉量表（FS））。所有条件下，CR10 和 FS 之间的相关性均较高（VICE=-0.987；HIIE-90/50=-0.873；HIIE-100/40=-0.908；HIIE-110/30=-0.948）。关于生理变量，在所有运动条件下，%HR 与 FS 呈中度反比关系（VICE=-0.867；HIIE-90/50=-0.818；HIIE-100/40=-0.837；HIIE-110/30=-0.828），而呼吸变量（%VO 和%VCO）仅在 VICE、HIIE-90/50 和 HIIE-100/40 中呈低至中度相关性（范围从-0.523 到-0.805）。%VO（r=-0.293）和%VCO（r=-0.020）与 FS 之间的相关性较差。结果表明，在 HIIE 运动中，感觉用力比生理变量更能敏感地解释强度与情感效价之间的关系。在 HIIE 处方中应使用 RPE，重点关注情感。
