چکیده انگلیسی
The aim of this study was to investigate the effects of 3 weeks high-intensity interval training (HIIT) on ventilatory efficiency (VE/VCO2 slope) in endurance athletes. Sixteen male well-trained (67.72â¯mlâ¯kgâ¯minâ1) athletes participated in this study. Each participant performed an incremental exercise test with gas analysis (i.e. VE, VO2) and a 400â¯m running field test (T400m) before and after the 3 weeks intervention period. HIIT group (HIITG) performed 11 HIIT sessions consisting of four 4-min interval bouts at an exercise intensity of 90-95% of the VO2max, separated by 4-min active recovery periods (work/rest ratioâ¯=â¯1:1). No significant differences were found in the parameters studied. Ventilatory efficiency (up to VT2 and up to exhaustion) did not show any change in HIITG after training intervention (ESâ¯=â¯0.24 HIITG; ESâ¯=â¯0.21 CG). No significant changes were observed on ventilation (VEmax; ESâ¯=â¯0.38). VO2max and T400â¯m did not show a significant improvement after the training period (no interaction timeâ¯Ãâ¯group, pâ¯<â¯.05) (ESâ¯=â¯0.43 and ESâ¯=â¯0.75 respectively). These results do not support the hypothesis that 3 weeks of HIIT could modify the ventilatory efficiency response in well-trained athletes. Furthermore, they show the lack of relationship between ventilatory efficiency and sport performance.
