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 (vVO2PEAK).MethodsThirty-one male athletes underwent an incremental exercise test involving 10 submaximal efforts (50–95% of velocity corresponding to VO2PEAK [vVO2PEAK]) and one supramaximal effort at 110% of vVO2PEAK to determine MAOD. We analyzed a combined group (n = 31) and two groups according to age (G1 = 15.5 ± 0.5; G2 = 36.0 ± 7.9 years).ResultsThe values of absolute VO2PEAK (4.3 ± 0.4 L·min−1) and vVO2PEAK (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 vVO2PEAK 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 vVO2PEAK (r = 0.43; r = 0.56).ConclusionsThe MAOD is influenced by chronological age and is related to VO2PEAK and vVO2PEAK independent of age.
