本研究的目的是：分析在上坡越野自行车的现场测试过程中的性能的再现性和相关的生理和人体测量因素与性能在这种方式。10名训练过的自行车运动员（19.5 ± 2.5岁，62.8 ± 8.7 kg，173.5 ± 6.8 cm，24.5 ± 19.0个月的训练）在不同的日子进行了以下测试：三个最大上坡性能在现场;逐渐连续测试，用于确定无氧阈值（AnT）和最大有氧功率（Pmax）;和Wingate测试。3次田间试验的平均成绩（622 ± 51.3; 614 ± 50.1; 620.6 ± 66.5 s）无显著差异，且高度相关（r = 0.84）。有氧变量（Pmax和AnT）仅在以单位体重表示时与最佳性能（P）呈现显著相关（分别为r = -0.73; r =-0.87）。有一个显着的相关性P与0%的体脂和疲劳指数通过Wingate测试（r = 0.72，r = 0.81，分别）。结果表明：山地自行车运动员爬坡成绩的评定方法是可靠的，其主要决定因素是单位体质量的AnT，说明有氧能力和身体成分对该项目运动员选材和训练的重要性。
The objectives of this study were: to analyze the reproducibility of the performance during a field test in uphill off-road cycling and to correlate physiological and anthropometrical factors with the performance in this modality. Ten trained cyclists (19.5 + 2.5 years, 62.8 + 8.7 kg, 173.5 + 6.8 cm, 24.5 + 19.0 months of training) performed, in different days, the following tests: three maximum uphill performances in the field; gradual continuous test for determination of the anaerobic threshold (AnT) and maximum aerobic power (Pmax); and Wingate test. The average values of performance of the 3 field tests (622 + 51.3; 614 + 50.1; 620.6 + 66.5 s) were not different and highly correlated (r = 0.84). The aerobic variables (Pmax and AnT) presented significant correlation with the best performance (P) only when expressed per unit of body mass (r = -0.73; r = -0.87, respectively). There was a significant correlation of P with 0% body fat and fatigue index obtained through the Wingate test (r = 0.72; r = 0.81, respectively). It can be concluded that the field test used to evaluate the performance in uphill off-road cycling is reliable, and that the main determinant factor of this performance is the AnT expressed per unit of body mass, indicating the importance of aerobic capacity and body composition on the selection and training of athletes of this sport.
