Abstract

PurposeThis study aimed to verify the influence of chronological age on maximal accumulated oxygen deficit (MAOD) and the correlations with maximal oxygen uptake (VO2PEAK) and intensity (vVO(2PEAK)).MethodsThirty-one male athletes underwent an incremental exercise test involving 10 submaximal efforts (50-95% of velocity corresponding to VO2PEAK [vVO(2PEAK)]) and one supramaximal effort at 110% of vVO(2PEAK) to determine MAOD. We analyzed a combined group (n=31) and two groups according to age (G1=15.50.5; G2=36.07.9 years).Results The values of absolute VO2PEAK (4.3 +/- 0.4 L.min(-1)) and vVO(2PEAK) (15.9 +/- 1.7 km.h(-1)) were higher in G2 than those in G1 (3.5 +/- 0.3 L.min(-1); 14.6 +/- 0.9 km.h(-1)). Individuals in G1 had absolute and relative values of MAOD (2.4 +/- 0.7 L; 35.1 +/- 11.1 mL.kg(-1)) lower than those in G2 (3.9 +/- 0.9 L; 46.8 +/- 10.9 mL.kg(-1)). Correlations between MAOD and performance during the experimental protocol were tested; VO2PEAK and vVO(2PEAK) yielded correlations with performance (n=31; r=0.56; r=0.60). Moreover, when corrected for chronological age, we detected correlations between absolute and relative values of MAOD and VO2PEAK (r=0.42; r=0.61) and vVO(2PEAK) (r=0.43; r=0.56).Conclusions The MAOD is influenced by chronological age and is related to VO2PEAK and vVO(2PEAK) independent of age.
