This study analyzed the relationship between anthropometric measures, cardiorespiratory capacity, strength, power, and local muscle endurance with performance in the CrossFit Open 2020. For this, 17 volunteers (6 women) (29.0 ± 7.2 years) completed, on separate weeks, tests for body composition (dual-energy X-ray absorptiometry), maximal oxygen consumption (2 km row test), muscle strength (one repetition maximum (1 RM) back and front squat, isometric peak torque), muscle power (1 RM snatch and clean and jerk) and muscle endurance (Tibana test), which were compared with performance during the CrossFit Open 2020. Specific tests of localized muscular endurance and muscle strength had the strongest relationship with performance in the CrossFit Open 2020. On the other hand, the percentage of fat and cardiorespiratory capacity were not significantly correlated with CrossFit Open 2020 workout performance. Coaches and practitioners should therefore utilize these findings to assess physical fitness and organize the distribution of the training session based on less developed physical needs, in order to ensure an appropriate physiological adaptation for a given competition.
本研究分析了人体测量指标、心肺功能、力量、功率和局部肌肉耐力与2020年CrossFit公开赛成绩之间的关系。为此，17名志愿者（6名女性）（29.0±7.2岁）在不同的周内分别完成了身体成分测试（双能X线吸收法）、最大摄氧量测试（2公里划船测试）、肌肉力量测试（深蹲和前蹲的一次重复最大值（1RM）、等长峰值扭矩）、肌肉功率测试（抓举和挺举的1RM）以及肌肉耐力测试（蒂巴纳测试），并将这些测试结果与2020年CrossFit公开赛期间的成绩进行了比较。局部肌肉耐力和肌肉力量的特定测试与2020年CrossFit公开赛的成绩关系最为密切。另一方面，体脂百分比和心肺功能与2020年CrossFit公开赛的训练表现没有显著相关性。因此，教练和从业者应利用这些研究结果来评估身体素质，并根据较薄弱的身体需求来安排训练课程的分配，以确保针对特定比赛进行适当的生理适应。
