Our purpose was to determine the possible association between genotypes of three polymorphisms ( Gly482Ser , Thr394Thr and A2962G ) of the peroxisome proliferator‐activated receptor γ coactivator 1α ( PPARGC1A ) gene, on one hand, and both the pre‐ (baseline) and post‐training levels of maximal (i.e., maximal oxygen uptake [VO 2max ]) and submaximal human endurance capacity (i.e., running economy [RE]). We studied 102 young males (physically active, non‐athletes; age: 19±1 yrs) from Northern China (of Han origin) who underwent a 18‐week endurance training (running) program and were tested on a treadmill (for VO 2max and RE determination) before and after training. None of the VO 2max and RE related traits were associated with the Gly482Ser and Thr394Thr polymorphisms at baseline or after training. The A2962G polymorphism was however associated with VO 2max at baseline, as carriers of the G allele ( AG + GG genotypes ; n =49) had higher levels of VO 2max than the AA group ( n =53) (58.2±4.3 vs 56.3±3.9 mL/kg/min; P =0.017). Our results do not support previous data on Caucasians showing an association between the Gly482Ser variant and VO 2max but suggest the potential role of another polymorphism ( A2962G ) to explain individual VO 2max differences in Chinese men.
