EFFECT OF THREE DIFFERENT PERIODIZATION OF ENDURANCE TRAINING ON VENTILATORY THRESHOLD
Abstract
This study aimed to compare the effect of aerobic training with different progressions of intensity on ventilatory threshold (VO2VT) and VO2peak. 48 men were divided into groups: incremental progression (INC), undulatory (UND) and stepped (STEP), and evaluated before and after 13 weeks of training, performed three times a week for 30 minutes. The lower and upper limit of the intensity were equal in all groups (65-90% HRmax.), but the progression was structured differently, making the training loads were distinct. There was an increase in both, VT (UND 29 ± 4 vs. 32 ± 4; INC 30 ± 4.6 vs. 34 ± 5.7; STEP 32.8 ± 4.6 vs. 35.7 ± 5. mL.kg-1. min-1) and VO2peak (UND 52.6 ± 7 vs. 57.8 ± 10; INC 53 ± 10 vs. 57.7 ± 10; STEP 54 ± 8 vs. 61.5 ± 9 mL.kg-1.min-1) in the three groups, with no differences between them. The three protocols were effective in increasing the VT and VO2peak despite differences in training loads.
