Physiological and Psychological Responses during Low-Volume High-Intensity Interval Training Sessions with Different Work-Recovery Durations

We compared physiological and psychological responses between low-volume high-intensity interval training (LV-HIIT) sessions with different work-recovery durations. Ten adult males performed two LV-HIIT sessions in a randomized, counterbalanced order. Specifically, 60/60 s LV-HIIT and 30/30 s LV-HII...

Description
Summary:We compared physiological and psychological responses between low-volume high-intensity interval training (LV-HIIT) sessions with different work-recovery durations. Ten adult males performed two LV-HIIT sessions in a randomized, counterbalanced order. Specifically, 60/60 s LV-HIIT and 30/30 s LV-HIIT. Oxygen uptake (V[O.sub.2]), carbon dioxide output (VC[O.sub.2]), ventilation (VE), respiratory exchange ratio (RER), perceived exertion (RPE), and affect were assessed. During intervals, the V[O.sub.2] (3.25 [+ or -] 0.57 vs. 2.83 [+ or -] 0.50 L/min), VC[O.sub.2] (3.15 [+ or -] 0.61 vs. 2.93 [+ or -] 0.58 L/min), VE (108.59 [+ or -] 27.39 vs. 94.28 [+ or -] 24.98 L/min), and RPE (15.9 [+ or -] 1.5 vs. 13.9 [+ or -] 1.5) were higher (ps < 0.01), while RER (0.98 [+ or -] 0.05 vs. 1.03 [+ or -] 0.03) and affect (-0.8 [+ or -] 1.4 vs. 1.1 [+ or -] 2.0) were lower (ps < 0.007) in the 60/60 s LV-HIIT. During recovery periods, V[O.sub.2] (1.85 [+ or -] 0.27 vs. 2.38 [+ or -] 0.46 L/min), VC[O.sub.2] (2.15 [+ or -] 0.35 vs. 2.44 [+ or -] 0.45 L/min), and affect (0.6 [+ or -] 1.7 vs. 1.7 [+ or -] 1.8) were lower (ps < 0.02), while RER (1.20 [+ or -] 0.05 vs. 1.03 [+ or -] 0.05; p < 0.001) was higher in the 60/60 s LV-HIIT. Shorter LV-HIIT (30 s) elicits lower physiological response and attenuated negative affect than longer LV-HIIT (60 s). Key words: Exercise, interval training, affective response, pleasure, physiological response.
