Abstract

The aim of this research was to establish the effects of the 8-week hypercapnic-hypoxic training program on hemoglobin concentration (Hb) and the maximum oxygen uptake (VO2max) in swimmers. The research was conducted on a sample of 16 Croatian elite male swimmers (experimental group n=8, control group n=8). Both groups were subjected to the same swimming trainings and additional training sessions on a treadmill. The experimental group was subjected additionally to hypercapnic-hypoxic training program with enhanced muscular activity. The experiment lasted for eight weeks. The following variables were used: hemoglobin concentration (Hb) and maximum oxygen uptake (VO2max). The ANOVA series application for the repeated measurements have shown significant Hb and VO2max concentration differences related to the effect of both
groups. The hypercapnic-hypoxic training method, which was applied to elite swimmers, has resulted in a 5.35% higher Hb concentration at the end of the program, which also caused a 10.79% increase in the VO2max.
