The main aim was to investigate the impact of maximal aerobic speed (MAS), maximal anaerobic speed (MANS), and time to exhaustion (TTE) at 130% MAS, on 800-m running time performance (800TT). A second aim was to investigate the impact of anaerobic speed reserve (ASR), i.e., the relative difference between MAS and MANS, on TTE. A total of 22 healthy students classified as recreational runners participated in a cross-sectional study. They were tested for maximal oxygen consumption (VO), oxygen cost of running (C), time performance at 100 m (100TT), time performance at 800 m (800TT), and TTE. MAS was calculated as VO × C , and MANS was calculated as 100TT velocity. Both MAS and MANS correlated individually with 800TT ( = -0.74 and -0.67, respectively, < 0.01), and the product of MAS and MANS correlated strongly ( = -0.82, < 0.01) with 800TT. TTE did not correlate with 800TT. Both ASR and % MANS correlated strongly with TTE ( = 0.90 and -0.90, respectively, < 0.01). These results showed that 800TT was first and foremost dependent on MAS and MANS, and with no impact from TTE. It seemed that TTE was merely a product of each runner's individual ASR. We suggest a simplified model of testing and training for 800TT, namely, by focusing on VO, C, and short sprint velocity, i.e., MAS and MANS.
主要目的是研究最大有氧速度（MAS）、最大无氧速度（MANS）以及在130%MAS时的力竭时间（TTE）对800米跑步成绩（800TT）的影响。第二个目的是研究无氧速度储备（ASR），即MAS和MANS之间的相对差异，对TTE的影响。共有22名被归类为业余跑步者的健康学生参与了一项横断面研究。他们接受了最大摄氧量（VO）、跑步耗氧率（C）、100米成绩（100TT）、800米成绩（800TT）和TTE测试。MAS通过VO×C计算得出，MANS通过100TT速度计算得出。MAS和MANS均分别与800TT相关（分别为r = -0.74和 -0.67，P < 0.01），且MAS与MANS的乘积与800TT高度相关（r = -0.82，P < 0.01）。TTE与800TT不相关。ASR和%MANS均与TTE高度相关（分别为r = 0.90和 -0.90，P < 0.01）。这些结果表明，800TT首先主要取决于MAS和MANS，而不受TTE的影响。似乎TTE仅仅是每个跑步者个体ASR的产物。我们建议针对800TT进行一种简化的测试和训练模型，即专注于VO、C和短跑速度，也就是MAS和MANS。
