This investigation aimed to explore the effects of  ACE  I/D and  ACTN3  R577X gene polymorphisms on specific quantitative variables, including height, weight, arm span, biacromial breadth, forced vital capacity (FVC), FVC/weight, maximal oxygen uptake (VO 2 max), prone bench pull (PBP), loaded barbell squat (LBS), and 3,000-m run, in 243 Chinese rowing athletes. The  ACE  and  ACTN3  genotypes were obtained for each athlete  via  polymerase chain reaction on saliva samples, and the genotype frequency was analyzed. The  ACE  genotype frequency of rowing athletes were 45.8% II, 42.2% ID, and 12% DD for males and 33.6% II, 48% ID, and 18.4% DD for females. There were significant differences in weight in male athletes, PBP in female athletes, and  ACE  genotypes. A linear regression analysis using PBP and LBS as different dependent variables and  ACE  genotypes as independent variables based on the  ACE  I allele additive genetic effect showed a statistical significance in female athletes ( p  < 0.05). There was a significant difference in the distribution of the three genotypes among male athletes (36.7% XX, 38.5% RX, and 24.8% RR,  χ 2 = 5.191, df = 2,  p  = 0.022 < 0.05). There were no significant differences in the distribution of the three genotypes among female athletes (23.8% XX, 47.8% RX, 28.4% RR,  χ   2  = 0.24, df = 2,  p  = 0.619 > 0.05). The  ACTN3  gene polymorphism of male rowing athletes was dominated by the  ACTN3  577X allele. There were significant differences in the  χ   2  test between groups of male athletes. The  ACTN3  R577 allele was dominant in female athletes. There were significant differences between PBP and FVC/body weight and  ACTN3  genotypes in male athletes by ANOVA, respectively ( p  < 0.05). A linear regression analysis using FVC and FVC/body weight as dependent variables and  ACTN3  genotypes as independent variables based on the  ACTN3  577X allele recessive genetic effect showed statistical significance in male athletes ( p  < 0.05). These results suggested that  ACE  and  ACTN3  gene polymorphisms may be used as biomarkers of genetic traits in Chinese rowing athletes.
