Abstract
Background
Progressive specific taekwondo test (PSTT) was designed to evaluate aerobic indicators and maximum frequency kick (FKMAX) in taekwondo athletes. Both can be used as specific aerobic power variables to estimate maximum oxygen uptake (VO2MAX).
Aim
To determine a linear regression equation to estimate the VO2MAX during PSTT in taekwondo athletes.
Methods
Twenty-two taekwondo athletes performed a PSTT. Oxygen consumption was measured and the equations to estimate VO2MAX were established by multiple linear regression. Regression coefficient (R), coefficient of determination (R2), and standard error of estimate (SEE) were stablished and p < 0.05 was considered.
Results
Two significant regression equations were obtained: VO2MAX absolute (L.min−1) = 7.230–0.029 (heart rate deflection point) + 0.048 (FKMAX), with R 0.616, R2 0.379, and SEE = 0.428; and VO2MAX relative (mL.kg−1.min−1) = 28.946 + 0.761 (FKMAX)—0.030 (height), with R = 0.622, R2 = 0.387, and SEE = 4.665
Conclusions
Significant but moderate multiple regression coefficients to predict absolute and relative VO2MAX were found. The SEE observed suggests that more control of the actions during the test (i.e., control of the kick speed or its impact and standardization of step intensity) must be established.
