Subjects produced a maximum voluntary isometric contraction
against the HHD in accordance with the “make” test. To the beat of a
metronome set at 60 beats-per-minute, they generated maximum
muscle force over a 2-s period and held the maximum force for a 5-
s period . Subjects performed
one practice and 3 test trials and received a 30-s rest between trials
. The order of testing was randomized to account
for any potential of order bias. The investigators calculated a coef-
ficient of variation for the 3 test trials and took an additional trial, if
necessary, to ensure that subjects provided 3 measures with less
than 10% variability
