Entrenamiento intervalado de alta intensidad en rugbistas juveniles de argentina

The aim of the present study was to evaluate the influence of a High Intensity Interval Training protocol with straight running on the aerobic performance on male rugby players between 15 and 16 years old. Thirty three subjects voluntarily participated in the proposed training. Anthropometric measurements and estimates of maximal oxygen uptake (VO2max) were taken to characterize the subjects in the initial physical state. Subsequently, the maximal aerobic speed was estimated to individually program the training distances. The protocol was organized in six sessions divided in three weeks, consisting of two rounds of twelve repetitions with work intervals of ten seconds of straight running and ten seconds of passive pause. After six sessions VO2max were evaluated again. In the statistical treatment, non-parametric tests were used. The experimental group achieved a significant increase in VO2max of 12% (p <0.01), while the control group increased its yield by 6.8% (p <0.05).
