The purpose of the current study was to investigate the relationship between alternative anaerobic capacity method (MAODALT) and a 30-s all-out tethered running test. Fourteen male recreational endurance runners underwent a graded exercise test, a supramaximal exhaustive effort and a 30-s all-out test on different days, interspaced by 48h. After verification of data normality (Shapiro-Wilk test), the Pearson's correlation test was used to verify the association between the anaerobic estimates from the MAODALT and the 30-s all-out tethered running outputs. Absolute MAODALT was correlated with mean power (r = 0.58; P = 0.03), total work (r = 0.57; P = 0.03), and mean force (r = 0.79; P = 0.001). In addition, energy from the glycolytic pathway (E[La-]) was correlated with mean power (r = 0.58; P = 0.03). Significant correlations were also found at each 5s interval between absolute MAODALT and force values (r between 0.75 and 0.84), and between force values and E[La-] (r between 0.73 to 0.80). In conclusion, the associations between absolute MAODALT and the mechanical outputs from the 30-s all-out tethered running test evidenced the importance of the anaerobic capacity for maintaining force during the course of time in short efforts.
本研究的目的是调查替代性无氧能力方法（MAODALT）与30秒全力束缚跑测试之间的关系。14名男性休闲耐力跑者在不同日期分别进行了分级运动测试、超最大力竭运动和30秒全力测试，每次测试间隔48小时。在验证数据正态性（Shapiro-Wilk检验）后，使用Pearson相关检验来验证MAODALT的无氧估计值与30秒全力束缚跑输出之间的关联。绝对MAODALT与平均功率（r = 0.58；P = 0.03）、总功（r = 0.57；P = 0.03）和平均力（r = 0.79；P = 0.001）相关。此外，糖酵解途径能量（E[La-]）与平均功率（r = 0.58；P = 0.03）相关。在绝对MAODALT与力值之间的每5秒间隔（r在0.75至0.84之间）以及力值与E[La-]之间（r在0.73至0.80之间）也发现了显著相关性。总之，绝对MAODALT与30秒全力束缚跑测试的机械输出之间的关联证明了无氧能力在短时间运动过程中维持力量的重要性。
