Brain-Derived Neurotropic Factor (BDNF) is one of the essential mediating factors of exercise-induced neuroplasticity, but the underlying molecular mechanisms of exercise-induced neuroplasticity are still largely unknown. Personality dimensions differentiate individuals and depend on genes and environmental factors. The dimensions of openness to experience, emotional stability, extraversion and conscientiousness have been reported to be positively related to performance; considering agreeableness, a negative relation with sports performance was emphasized. However, not enough effort has been put into investigating the relationship between genetic polymorphisms affecting psychological abilities and competitive power sports. The aim of this study was to investigate the association of the rs6265 polymorphism of BDNF with personality dimensions in martial arts athletes. The study was conducted among martial arts athletes. The study group included 258 volunteers (martial arts athletes (n = 106) and controls (n = 152). BDNF polymorphism testing was performed using the real-time PCR method; personality dimensions were assessed using standardized NEO-FFI questionnaires. All analyses were performed using STATISTICA 13. We observed that martial arts athletes’ G/G genotypes compared to the control group G/G genotypes presented significantly higher severity of personality dimension “conscientiousness”. In comparison with the controls, the case group subjects had significantly higher scores in the dimension extraversion (M 6.89 vs. M 6.43, p = 0.0405) and conscientiousness/scale (M 7.23 vs. M 5.89, p < 0.0001). The results of 2 × 3 factorial ANOVA noticed a statistically significant effect of combined factor BDNF rs6265 genotype of martial arts/control (F2,252 = 3.11, p = 0.0465, η2 = 0.024). Additionally, we observed that the results of 2 × 3 factorial ANOVA showed a statistically significant influence of combined factor BDNF rs6265 of genotype martial arts/ control (F2,252 = 6.16, p = 0.0024, η2 = 0.047). The combination of the analysis of personality dimensions with genetics—as in the case of the polymorphism of the BDNF gene related to neuroplasticity—indicates that neurobiology cannot be ignored in educating sports champions. We already know that this is related to genetics. However, little is still known about the influence of personality traits on sports performance. We observed that martial arts athletes’ G/G genotypes, in comparison to the control group’s G/G genotypes, presented significantly higher severity of personality dimension “conscientiousness”. This is worthy of further analysis and probably longitudinal studies on a more numerous group of athletes.
脑源性神经营养因子(BDNF)是运动诱导神经可塑性的重要调节因子之一,但运动诱导神经可塑性的潜在分子机制在很大程度上仍然未知。人格维度将个体区分开来,取决于基因和环境因素。开放性、情绪稳定性、外向性和尽责性等维度已被报道与表现呈正相关;考虑到宜人性,与运动表现呈负相关。然而,人们并没有足够努力地研究影响心理能力和竞技体育的遗传多态性与竞争力之间的关系。本研究旨在探讨 BDNF 基因 rs6265 多态性与武术运动员人格维度的关系。本研究在武术运动员中进行。研究组包括 258 名志愿者(武术运动员(n=106)和对照组(n=152)。使用实时 PCR 法进行 BDNF 多态性检测;使用标准化 NEO-FFI 问卷评估人格维度。所有分析均使用 STATISTICA 13 进行。我们观察到,与对照组的 G/G 基因型相比,武术运动员的 G/G 基因型表现出人格维度“尽责性”的严重程度明显更高。与对照组相比,病例组受试者在维度外向性(M 6.89 与 M 6.43,p=0.0405)和尽责性/量表(M 7.23 与 M 5.89,p<0.0001)方面的得分明显更高。2×3 因子方差分析的结果注意到联合因子 BDNF rs6265 基因型武术/对照(F2,252=3.11,p=0.0465,η2=0.024)的统计学显著影响。此外,我们观察到 2×3 因子方差分析的结果显示,联合因子 BDNF rs6265 的基因型武术/对照(F2,252=6.16,p=0.0024,η2=0.047)的统计学显著影响。人格维度与遗传学的结合分析——就与神经可塑性相关的 BDNF 基因多态性而言——表明在培养体育冠军时,神经生物学不容忽视。我们已经知道这与遗传学有关。然而,关于人格特质对运动表现的影响,我们知之甚少。我们观察到,与对照组的 G/G 基因型相比,武术运动员的 G/G 基因型表现出人格维度“尽责性”的严重程度明显更高。这值得进一步分析,可能需要对更多运动员进行更长期的研究。
