Recreational climbers are more conscientious than recreational athletes-a case control study

BACKGROUND

Physiological characteristics of climbers have been extensively studied, while the personality of climbers remains poorly understood. Personality research in sports is an established field, predicting long-term success as well as short-term behavior. The goal of our study was to examine recreational climbers' personality and gain a better understanding of what makes them reach new heights.

METHODS

We analyzed a cohort of 50 recreational climbers and 50 non-climbing athletes (control) regarding their personality characteristics. We assessed the BMI, the self-reported climbing grade, and the years of climbing experience. To evaluate the personality of recreational climbers and athletes, we used the German version of the Big Five Inventory (BFI-2), which summarizes the personality in five main categories.

RESULTS

Recreational climbers scored significantly higher in conscientiousness than non-climbing athletes (p = 0.04), there was no significant difference between the other four main personality traits. Female climbers scored significantly higher in conscientiousness than male climbers (p = 0.02), while female athletes scored higher in openness than male athletes (p < 0.01). The climbing group displayed a small but significant negative correlation between conscientiousness and BMI (r = -0.39; p < 0.01).

CONCLUSION

In conclusion, the personality of recreational climbers and recreational athletes differs in conscientiousness, with the climbers showing higher scores. Regarding gender, we found higher levels of conscientiousness in female climbers and higher openness in female athletes in comparison to their male counterparts. A negative correlation between BMI and conscientiousness of the climbers was detected.

Association between MCT1 T1470A polymorphism and climbing status in Polish and Japanese climbers

Sport climbing will become an official event at the 2020 Tokyo Olympics; it is a popular wilderness sport among athletes and amateurs. Our previous study suggested that the T1470A polymorphism (rs1049434) of the monocarboxylate transporter 1 (MCT1) gene is associated with athletic performance and physiological phenotypes. The purpose of this study was to investigate the frequency of MCT1 T1470A polymorphism in Polish and Japanese climbers using a case-control study. Our sample consisted of 226 climbers (Japanese: n = 100, 64 male and 36 female; Polish: n = 126, 97 male and 29 female) and 1028 non-athletic controls (Japanese, n = 407; Polish = 621) who were genotyped for the MCT1 T1470A polymorphism (rs1049434) using the TaqMan SNP genotyping assay or restriction enzyme. The frequency of the TT genotype and T allele was significantly higher in climbers than in controls among the Polish subjects (genotype: p = 0.030, allele: p = 0.010); however, there were no significant differences in the genotype and allelic frequencies between the Japanese climbers and controls (genotype: p = 0.968; allele: p = 0.803). Our results suggested that the frequency of the T allele (TT+TA genotype) in the MCT1 T1470A polymorphism is over-represented in Polish climbers but not in Japanese climbers. In addition, the frequency of the T allele and TT genotype in Polish lead climbers is higher than that in controls.
