AIM: In view of designing an effective training program and achieving performance in sports involving both effort capacities, it is important to understand how the development of one energy system impacts the other one. The aim of this study was to analyze the correlation between anaerobic parameters, tested simultaneously via two different evaluation methods, and aerobic parameters in elite endurance athletes. At the same time, the study checks the theory of “concurrent training” using the statistical analysis of the parameters obtained.
METHODS: Seventy athletes, divided in male and female groups, with 8.13±3.42, respectively 7.89±2.31 years of training experience were tested. The aerobic capacity was tested by measuring the oxygen uptake through Bruce protocol and the anaerobic one simultaneously trough Wingate test - by the measuring of Peak Power (PP), Average Power (AP), Fatigue Index (FI) and Szogy and Cherebetiu test – Total Work Performed during 10s (TWP10s), 20s (TWP20s) and 45s (TWP45s) of maximal exercise.
RESULTS: The results revealed a negative correlation between VO2max and the anaerobic parameters proposed by Szogy and Cherebetiu in both groups. This tendency was maintained when VO2max was compared with the parameters proposed by the Wingate Test, but the correlation coefficient was significant only for VO2max versus AP in case of the female group. The correlations between TWP10s and PP were positive with a very high significance degree (r=0.59 in men and of r=0.73 in women, with P<0.001). An even higher negative correlation was obtained between TWP45s and AP (r=0.94 in men and r=0.9 in women, P<0.001).
CONCLUSION: The negative correlations obtained in this study between VO2max and the anaerobic parameters are supporting the theory of fibers’ conversion. It appears in conclusion that for the athletes trained for elite endurance, the increased muscle oxidative potential is achieved at the expense of the glycoltic one.
