RESUMO:

Purpose: To compare the physiological and psychological responses during and following (24 and 48 h) a single session of low-volume high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) in overweight/obese inactive adults. Methods: Twenty males (29.0 ± 5.0 years, 29.0 ± 3.7 kg.m^-2) performed a single session of HIIE and MICE with one-week interval in a randomized and crossover order: i) HIIE (10 x 1 min at 85% of VO_2max, 1 min passive recovery); ii) MICE (20 min at 40-60% of VO_2max). The exercise sessions were isocaloric. During the exercise sessions the rating of perceived exertion (RPE), basic affect, perceived activation, self-efficacy, and oxygen uptake (VO₂) were assessed. Immediately post-exercise the attentional focus, enjoyment, and future intention to engage in HIIE and MICE were measured. Before, 24 h, and 48 h post-exercise creatine kinase (CK), lactate dehydrogenase (LDH), interleukin-6 (IL-6), IL-10, and tumor necrosis factor alpha (TNF-α), pain threshold, tolerance and intensity in rectus femoris, biceps femoris, and gastrocnemius were assessed. Results: During the exercise, RPE, perceived activation, VO₂, and distress thoughts were higher in the HIIE than in the MICE (P ≤ 0.02). Basic affect and self-efficacy were lower in the HIIE than in the MICE (P < 0.01). There was no difference in the enjoyment (P = 0.30) and future intention to engage in HIIE and MICE (P = 0.26). Also, there were no diferences in CK, LDH, IL-6, IL-10, TNF-α, and pain threshold, tolerance and intensity in all muscle analyzed 24 and 48 h post-exercise between HIIE and MICE (P ≥ 0.19). Conclusion: HIIE elicits aversive psychological responses in overweigth/obese adults, which does not occur during MICE. However, 24 and 48 h the muscle damage, inflammatory response, and delayed-onsed muscle soreness is similar between HIIE and MICE in these individuals.
