RESUMO

The popularity of endurance training in children and adolescents has increased considerably since the last decade (FLECK and KRAEMER, 2004), becoming one of the most popular forms of exercise, both to improve the physical training of athletes and to improve physical fitness. The purpose of this study was to examine the effects of different intensities of endurance training (5RM, 10RM, 15RM) in subjective perception of exertion and blood lactate concentrations at different intervals of muscle recovery between sets of exercise endurance in young athletes. For this we selected 23 male adolescents with average age (17,06 0,73), were submitted to the appropriateness of charges and was assessed after each intensity (5RM, 10RM or 15RM) and a range of recovery (30, 60 or 120 seconds) in the exercise of the extension of knees, held the chair extensor apparatus, where after each series was asked to indicate the assessed immediately at the end of the implementation of the series, the perceived exertion scale in the OMNI-RES for resistance exercises and also before and after 3 minutes of the three series of 25μm blood was collected from ear lobe for analysis of lactate. The statistical analysis used was the Three-way ANOVA [time (pre and post range) interval between the series x (30, 60 and 120 seconds) x intensity (5RM, 10RM and 15RM) for repeated measures (within within x)]. For the characterization of the sample was used descriptive statistical analysis, obtaining mean and standard deviation. The significant differences in ANOVA were analyzed by post-hoc test of Bonferroni. The significance level was 0.05. The study in question showed that by increasing the number of repetitions was also increased blood lactate concentrations and a possible removal of blood lactate was observed in intervals of 60 "and 120" when compared to the values found in samples pre-exercise in intensity 5 MR. The subjective perception of effort between RPE showed that the intensities and intervals of recovery were significant differences, demonstrating that the RPE has a positive linear relationship with the increment of mechanical overload. It is concluded that short periods of recovery can significantly raise blood lactate concentrations when compared to longer periods and there is an inverse relationship to the range of recovery and RPE, so, the smaller the range of recovery, the greater the levels of fatigue.
