Efeitos de diferentes protocolos de treinamento sobre variáveis fisiológicas e psicométricas de ciclistas treinados.

Abstract

The continuous method consumes about 80% of training in endurance sports such as cycling, however, also seen significant results with application of interval training in the modality. One of the most important points of the training prescription is appropriate distribution of stimuli over the planning period. For this, various ways are attempted to quantify responses generated by training, for example, from the autonomic nervous system (ANS) modulation on the heart activity. The aim of this study was to verify the effects of three training protocols, one continuous and two intermittent, on the internal load from heart rate (HR), HR variability (HRV), rate of perceived exertion (RPE) and training impulse (TRIMP). It was a counterbalanced study with repeated measures and the sample was composed by 12 male cyclists. All of them performed the until exhaustion progressive test to determine the maximal and anaerobic threshold (aT) associated loads, like the power output (aTP). Subsequently, underwent three sessions on consecutive days for each training protocol proposed. Continuous protocol (T1): 30 min at 70% of ATP; Threshold interval protocol (T2): 6 x 4 min at 90-95% of aTP : 1 min at 0,50 Kp; and Above threshold interval protocol (T3): 8 x 1 min at 120% of aTP : 3 min at 0,50 Kp. Statistical analysis was performed by two-way ANOVA. As a results, it was found that RPE, maximum and mean HR, MeanRR, RMSSD and LF/HF represented greater impact with T2 on at least one post-training moments compared to T1 and T3, with no differences between days, while in other variables (SDNN, LF, HF e TP) not succeeded differences at any time. Conclusions: Training conducted in nearby anaerobic threshold intensities are more impactful than others made with inferior or superior to him efforts, but there is no cumulative effect of internal overload on consecutive days of workout.
