Based on gender and exercise type, university elite athletes were divided into four groups: endurance/male (n = 57), sprint/male (n = 89), endurance/female (n = 57), and sprint/female (n = 121). Simultaneously, age-matched sedentary/healthy control/male (n = 100) and control/female (n = 100) were also recruited. We examined the body composition, calcaneus broadband ultrasound attenuation (BUA), dietary behavior and exercise status, and the genotypes of ACE (I/D alleles), ACTN3 (R/X alleles), and AGT (M/T alleles) of each participant. The energy (p＜.0001), protein intake (g/kg/day; p＜.001), fat-free mass (%; p＜.0001), and BUA (p＜.01) of male athlete groups were significantly higher than those of the control/male group, respectively. The energy intake (p＜.05) of endurance/female group was significantly higher than that of the control/female group. The protein intake percentage (p＜.0001) and protein intake on a body weight basis (p＜.01) of female athlete groups were significantly higher than those of the control/female group, respectively. The fat-free mass (%; p＜.0001) and BUA (p＜.0001) of female athlete groups were significantly higher than those of the control/female group, respectively. The fat-free mass (%; p＜.0001) and BUA (p＜.0001) of the sprint/female group were also significantly higher than those of the endurance/female group, respectively. Furthermore, the protein intake, on either basis, of the sprint group was significantly higher (p< .05) than that of the corresponding endurance group for both genders. The ACE genotype distribution in endurance/male (p＜.05), sprint/male (p＜.05), or endurance/female (p＜.05) group was significantly different from that of the corresponding control group, as well as the ACE genotype distribution between the endurance and sprint groups for both genders (p＜.001). There were significant differences in ACTN3 genotype distribution among the three female groups (p＜.01). The distribution of AGT genotype, however, was no different among all the groups (p＞.05). According to the multiple regression analysis, the training duration (years), protein intake (g/kg/day), energy intake, and ACE gene explained 19.0% of the variation of FFM (%) in the female athletes (R2 = 0.190, P< 0.001). Both ACE genotype and protein intake might play roles in Taiwanese elite athletes’ performance. ACTN3 genotype, however, may benefit the performance of Taiwanese elite female athletes only.身體組成飲食調查運動類型ACE基因ACTN3基因AGT基因body compositiondietary surveyexercise typeACEACTN3AGT
