Popis: | PurposeTraining near$$\dot{V}$$V˙O2max is considered to be the most effective way to enhance$$\dot{V}$$V˙O2max. High-intensity interval training (HIIT) is a well-known time-efficient training method for improving cardiorespiratory and metabolic function and$$\dot{V}$$V˙O2max. While long HIIT bouts allow$$\dot{V}$$V˙O2max to be achieved quickly, short HIIT bouts improve time to exhaustion (Tlim). The aim of this study was to evaluate the time spent above 90%$$\dot{V}$$V˙O2peak (T > 90%$$\dot{V}$$V˙O2peak) during three different HIIT protocols.MethodsTwelve cyclists performed three HIIT sessions. Each protocol had the same work and recovery power and ratio of work·recovery−1. The protocols consisted of long-interval HIIT (LIHIIT, 3 min work—2 min recovery), short-interval HIIT (SIHIIT, 30 s work—20 s recovery), and high-intensity decreasing interval training (HIDIT, work from 3 min to 30 s and recovery from 2 min to 20 s).T > 90%$$\dot{V}$$V˙O2peak, Tlim, blood lactate [La], and rate of perceived exertion (RPE) were measured at Tlim.ResultsT > 90%$$\dot{V}$$V˙O2peak was greater in HIDIT (312 ± 207 s) than in SIHIIT(182 ± 225 s;P = 0.036) or LIHIIT(179 ± 145 s;P = 0.027). Tlim was not significantly different (P > 0.05) between HIDIT (798 ± 185 s), SIHIIT(714 ± 265 s), and LIHIIT(664 ± 282). At Tlim, no differences in [La] and RPE were found between protocols (P > 0.05).ConclusionHIDIT showed the highestT > 90%$$\dot{V}$$V˙O2peak, suggesting that it may be a good strategy to increase time close to$$\dot{V}$$V˙O2peak, despite similar Tlim, [La], and RPE at Tlim. |
