Abbreviations: BF, biceps femoris; LG, lateral gastrocnemius; TA, tibialis anterior; and VL, vastus lateralis. Muscles that were not correlated with net metabolic power are denoted as non-significant (n.s.). The average correlation coefficient, standard error and the number of participants with significant correlations are presented in the last two rows of the table.
