Abstract
- At least 69 genetic markers are associated with power athlete status. In the present study, we investigated the genotype frequency of the ciliary neurotrophic factor receptor (CNTFR) rs41274853 polymorphism and the association between specific CNTFR genotype and weightlifting performance in Japanese weightlifters. One hundred sixty-five Japanese weightlifters (103 men and 62 women) and 338 controls (122 men and 216 women) participated in the present casecontrol study. Saliva samples were collected using the Oragene DNA self-collection kit and genotyping for the CNTFR (rs41274853) polymorphism was performed using the TaqMan assay. A questionnaire, noting each subject's best record in an official weightlifting competition, was used to obtain the weightlifting performance. The frequencies of the CNTFR genotypes CC, CT, and TT were 56, 32, 12% in the weightlifters, and 53, 40, and7%in the controls, respectively. There was no significant difference in CNTFR genotype frequencies between the weightlifters and controls. However, the frequency of the CT + TT genotype was significantly higher in international-level weightlifters than in the national-level weightlifters. The relative value per body weight of snatch, clean, and jerk, and total record were significantly higher in the athletes with CT + TT genotype than in the athletes with CC genotype (p < 0.05). Our results suggest that the CNTFR rs41274853 CT + TT genotype is associated with weightlifting performance in Japanese weightlifters. The CNTFR rs41274853 polymorphism may enable coaches to develop tailor-made training programs for individual athletes. In addition, strength and conditioning coaches could benefit from genetic information when assessing potential athletic talents and creating strength training programs for their athletes.
