Resumen

Introduction. Physical exercise is a key modulator of the maximum fat oxidation rate (MFO). However, the metabolic transition zones in the MFO-exercise relationship are not generally considered for training prescription. Objective. To examine the effects of training in different metabolic transition zones on the kinetics of MFO and its localization (Fatmax) in young physically active men. Methods. 97 men were divided into 4 similar sized groups, 3 experimental groups and a control group (CG). Subjects in each experimental group undertook an 8-week running program. Training was continuous at the intensity of the aerobic threshold or VT1 (CCVT1); or performed as intervals at the intensity of the anaerobic threshold or VT2 (ITVT2); or at maximum aerobic power VO2max (ITVO2max). Before and after the training intervention, expired gases were monitored in each subject to determine VO2max, VT1, VT2, MFO (by indirect calorimetry) and Fatmax. Results. In response to training, experimental groups showed an increase in MFO (from 16,49 to 18,51%; p<0,01) and a mean reduction in Fatmax of 60,72±10,52 to 52,35±7,61 %VO2max(p<0,01). No changes of interest were observed in the control subjects. Intergroup comparisons revealed no differences in MFO and Fatmax among the experimental groups, though compared to the CG, a greater reduction in Fatmax was observed in CCVT1 (p<0,05). No changes were detected in performance except a drop in VO2maxin the GC (p<0,05). Conclusion. 8 weeks of training led to an increase in MFO and reduction in Fatmax irrespective of training intensity.
