- Abstract
This study examined the effects of four high-intensity interval-training (HIT) sessions performed over 2 weeks on peak volume of oxygen uptake (VO[sub 2peak]), the first and second ventilatory thresholds (VT[sub 1], VT[sub 2]) and peak power output (PPO) in highly trained cyclists. Fourteen highly trained male cyclists (VO[sub 2peak] = 67.5 ± 3.7 ml · kg[sup −1] · min[sup −1]) performed a ramped cycle test to determine VO[sub 2peak], VT[sub 1], VT[sub 2], and PPO. Subjects were divided equally into a HIT group and a control group. The HIT group performed four HIT sessions (20 × 60 s at PPO, 120 s recovery); the VO[sub 2peak] test was repeated <1 wk after the HIT program. Control subjects maintained their regular training program and were reassessed under the same timeline. There was no change in VO[sub 2peak] for either group; however, the HIT group showed a significantly greater increase in VT[sub 1] (+22% vs. −3%), VT[sub 2] (+15% vs. −1%), and PPO (+4.3 vs. −.4%) compared to controls (all P < .05). This study has demonstrated that HIT can improve VT[sub 1], VT[sub 2], and PPO, following only four HIT sessions in already highly trained cyclists. Cette étude analyse, chez des cyclistes très bien entraînés, les effets de quatre séances intenses d'entraînement par intervalle réparties sur deux semaines; l'dvaluation porte sur la consommation d'oxygène de crête (VO[sub 2crête]), le premier et le deuxième seuils ventilatoires (VT[sub 1], VT[sub 2]) et la puissance de pointe (PPO). Quatorze cyclistes très bien entraînés (VO[sub 2crête] = 67, 5 ± 3, 7 mL · kg[sup −1] · min[sup −1]) participent à une& acute;epreuve d'effort progressif pour établir leurs VO[sub 2crête], VT[sub 1], VT[sub 2], et PPO. Les sujets sont ensuite répartis également...
