Perceptual Responses to High- and Moderate-Intensity Interval Exercise in Adolescents

We examined the acute affective, enjoyment, and perceived exertion responses to HIIE compared with moderate-intensity interval exercise (MIIE) in adolescents. Methods Thirteen adolescent boys (mean ± SD: age, 14.0 ± 0.5 yr) performed two counterbalanced exercise conditions: 1) HIIE: 8 × 1-min work intervals at 90% maximal aerobic speed; and 2) MIIE: between 9 and 12 × 1-min work intervals at 90% ventilatory threshold where the number of intervals performed were distance-matched to HIIE. HIIE and MIIE work intervals were interspersed with 75 s active recovery at 4 km·h−1. Affect, enjoyment, and RPE were recorded before, during, and after exercise. Results Affect responses declined in both conditions but the fall was greater in HIIE than MIIE (P
