Abstract: Background: In cricket, aerobic capacity (VO2 max) facilitates sustained performance across extended match lengths, recuperation in between overs, and repeated sprint ability. VO2 max may be impacted by age, training age, and role-specific demands (quick bowling vs. spin, batting vs. fielding effort).

Objective: To compare the aerobic fitness between Under-22 and Senior (≥22 years) male division cricket players.

Methods:The purpose of this study was to compare the aerobic fitness (VO2 max) of division level male cricket players. There was 35 (N=35) trained male division level cricketers chosen for this study from Narmadapuram Division Cricket Association (NDCA), Madhya Pradesh, India. Researcher were selected 02 active cricket groups (a) U-22 Boys {n=18} (b) Senior Boys {n=17}. An estimation of VO2 max was calculated from the test results, using YO-YO Intermittent Recovery level-1 (YYIR1 test): (mL * kg^-1 * min^-1) = IR1 distance (m) × 0.0084 + 36.4.Normality was checked by using skewness and kurtosis value in descriptive summary;group differences tested with independent t‑tests.

Results: Both groups displayed marginally similar mean values and significantly similar VO2 max. The study also revealed that VO2max of male cricket players of selected groups was in average range according to the norms and earlier research.

Conclusion: Differences in VO2 max between U-22 and Senior Boys division level players appearedsimilar. Conditioning programs are almost sameand prioritize aerobic maintenance in seniors and U-22 Boys development might be the reason behind same results.
