Table 3. Comparison of external load and perceptual responses between HIIT-C and HIIT-FS protocols. HIIT-C HIIT-FS Δ Total Distance (m) 2298 ± 142 2337 ± 154 38.6 Distance D 7 km.h-1 (m) 2118 ± 140 2132 ± 145 14.3 Distance D 16 km.h-1 (m) 1483 ± 451 1345 ± 381 137.4 MW distance (m) 148 ± 27 151 ± 24 2.8 RPE (0-10) 7.8 ± 0.7 9* ± 0.5 1.2 *: significant (p ≤ 0.05) different from HIIT-C. Values are mean ±SD. Distance S 7 km.h-1: distance covered at speeds greater than 7 km.h-1. Distance D 16 km.h-1: distance covered at speeds greater than 7 km.h-1 MW distance: distance covered greater than 2 m.s -1 during both acceleration and deceleration phases. RPE: rating of perceived exertion with the Borg CR10 Scale.
