Abstract
Perceptual responses are related to long-term exercise adherence. This within-subjects study compared blood lactate concentration (BLa) and perceptual responses to reduced exertion high intensity interval (REHIT) between rowing and cycle ergometry. Twenty healthy, active adults (age = 27 ± 6 yr) underwent a VO2max test followed by completion of REHIT on the rower or cycle ergometer. Exercise consisted of three "all-out" 20 s sprints separated by active recovery. BLa, affective valence, rating of perceived exertion (RPE 6 - 20), and enjoyment were acquired during exercise. Results showed no difference in peak HR (98 ± 6 vs. 95 ± 4 %HRmax, p = .06) or maximal workload (191 ± 34 vs. 204 ± 29 %Wmax, p = .25) between rowing and cycling REHIT. Rowing REHIT exhibited significantly lower BLa (p < .001) at 2, 30, and 60 min post-exercise (7.0 ± 2.2 vs. 11.6 ± 2.8 mM, p < .001, d = 1.9; 3.1 ± 1.5 vs. 6.2 ± 2.8 mM, p < .001, d = 1.4; and 2.0 ± 0.7 vs. 3.1 ± 1.3 mM, p = .02, d = 1.2) versus cycling. Results also showed significantly greater enjoyment (101 ± 12 vs. 89 ± 17, p < .001, d = 0.84) and lower change in RPE (7.8 ± 2.0 vs. 9.5 ± 2.1, p = .001, d = 0.85) and affective valence (-1.2 ± 1.5 vs. -2.4 ± 2.7, p = .036, d = 0.54) with rowing versus cycling REHIT. Overall, rowing REHIT elicits a more positive perceptual response versus cycling.
知觉反应与长期坚持锻炼有关。本研究比较了赛艇和周期几何之间的血乳酸浓度（BLa）和运动强度间隔（REHIT）降低时的知觉反应。20名健康、活跃的成年人（年龄= 27±6岁）接受了VO2max测试，随后在划船或自行车测力仪上完成REHIT。运动包括三次“全力以赴”的20秒冲刺，中间间隔着积极的恢复。在运动中获得BLa、情感效价、感知运动等级（RPE 6 - 20）和享受。结果显示，划船和骑自行车的REHIT在峰值心率（98±6 vs 95±4 %HRmax, p = 0.06）和最大负荷（191±34 vs 204±29 %Wmax, p = 0.25）上没有差异。划船REHIT在运动后2、30和60分钟时BLa显著降低（p < 0.001）(7.0±2.2 vs. 11.6±2.8 mM, p < 0.001, d = 1.9；3.1±1.5 vs. 6.2±2.8 mM, p < 0.001, d = 1.4；2.0±0.7 mM vs. 3.1±1.3 mM, p = 0.02, d = 1.2)。结果还显示，划船与骑自行车的REHIT组在RPE（7.8±2.0 vs. 9.5±2.1,p = 0.001, d = 0.85）和情感效价（-1.2±1.5 vs. -2.4±2.7,p = 0.036, d = 0.54）方面的变化显著高于骑车组（101±12 vs. 89±17,p < 0.001, d = 0.84）。总的来说，与骑车相比，划船会引起更积极的知觉反应。
