SILVA-CAVALCANTE, Marcos David et al. Estimation of contributions of the anaerobic lactic and alactic systems during constant-load exercises at intensities below the VO2max. Rev. Bras. Educ. Fís. Esporte [online]. 2013, vol.27, n.02, pp.209-216. ISSN 1981-4690.
The purpose this study was that estimated contributions of the anaerobic lactic (MAL) and alactic (MAA) metabolism during constant load exercises at intensities below the maximal oxygen capacity uptake ( VO2max). Ten males (23 ± 4 years, 176.4 ± 6.8 cm, 72.4 ± 8.2 kg, 12.0 ± 4.5 % of fat body) performed in the first visit a progressive test until exhaustion to identification of VO2max, power output corresponding to the VO2max (WVO2max) and second ventilatory threshold (LV2). On the second and third visit, the participants performed six constant workload tests (3 per session) with intensities below VO2max. There was a predominance of MAL about MAA during the exercises sub-maximal from intensity corresponding to the LV2, being significantly higher at 90% O2max (p < 0.05). Thus, these results may help coaches to implement training loads appropriate to their athletes, according to the metabolic demand of the competition.
