Abstract: The most typical maximum tests for measuring leg muscle performance
are the one-repetition maximum leg press test (1RMleg) and the isokinetic knee
extension/flexion (IKEF) test. Nevertheless, their inter-correlations have not
been well documented, mainly the predicted values of these evaluations. This
correlational and regression analysis study involved 30 healthy young males
aged 18–24y, who have performed both tests. Pearson's product moment
correlation between 1RMleg and IKEF varied from 0.20 to 0.69 and the more exact
predicted test was to 1RMleg (R^{2} =0.71). The study showed
correlations between 1RMleg and IKEF although these tests are different
(isotonic vs. isokinetic) and provided further support for cross determination
of 1RMleg and IKEF by linear and multiple linear regression analysis.
