There is extensive knowledge about uphill running on a treadmill, although paucity regarding the influence of uphill trail running on exercise capacity in runners. The purpose of this study was to compare an uphill field test with a treadmill test with 1% inclination especially considering cardiopulmonary exercise variables. The difference in those tests between a group of trail runners and a group of road runners was tested for establishing a test specifically for trail runners. Ten male endurance road runners and ten male trail runners performed one maximal incremental treadmill test with 1% inclination and a maximal incremental field test on a hill at 16% inclination which they were instructed to run up four times for three minutes, each time with a higher pace. A mobile cardiopulmonary exercise testing unit was used to measure ventilation. There were no significant differences between trail runners and road runners. The equivalence factor was comparable between both groups. was comparable for both test protocols. However, there was a significant difference between the two test protocols regarding lactate concentration, the respiratory exchange ratio, running cost, heart rate, Breathing reserve, and O. The greater lactate concentration and running cost recorded uphill indicate a higher energy demand during trail running than level road running.
关于在跑步机上进行上坡跑已有广泛的知识，但关于上坡越野跑对跑步者运动能力的影响却知之甚少。本研究的目的是比较上坡实地测试和坡度为1%的跑步机测试，尤其考虑心肺运动变量。对一组越野跑者和一组公路跑者在这些测试中的差异进行了测试，以建立专门针对越野跑者的测试。十名男性耐力公路跑者和十名男性越野跑者进行了一次坡度为1%的最大递增跑步机测试，以及一次在坡度为16%的山坡上进行的最大递增实地测试，他们被要求以更快的速度四次跑上三分钟。使用移动心肺运动测试装置测量通气量。越野跑者和公路跑者之间没有显著差异。两组的等效因子具有可比性。两种测试方案具有可比性。然而，在乳酸浓度、呼吸交换率、跑步成本、心率、呼吸储备和摄氧量方面，两种测试方案之间存在显著差异。上坡时记录到的更高的乳酸浓度和跑步成本表明，越野跑期间的能量需求高于平路跑步。
