The purpose of the current study was to investigate the relationship between alternative anaerobic capacity method (MAOD ALT ) 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 MAOD ALT and the 30-s all-out tethered running outputs. Absolute MAOD ALT 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 MAOD ALT 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 MAOD ALT 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.
