Abstract: The purpose of this investigation was to compare
4 different methods of calculating volume when comparing
resistance exercise protocols of varying intensities. Ten
Appalachian State University students experienced in resistance
exercise completed 3 different resistance exercise
protocols on different days using a randomized, crossover
design, with 1 week of rest between each protocol. The
protocols included 1) hypertrophy: 4 sets of 10 repetitions in
the squat at 75% of a 1-repetition maximum (1RM) (90-second
rest periods); 2) strength: 11 sets of 3 repetitions at 90% 1RM
(5-minute rest periods); and 3) power: 8 sets of 6 repetitions of
jump squats at 0% 1RM (3-minute rest periods). The volume
of resistance exercise completed during each protocol was
determined with 4 different methods: 1) volume load (VL)
(repetitions [no.] 3 external load [kg]); 2) maximum dynamic
strength volume load (MDSVL) (repetitions [no.] 3 [body mass
2 shank mass (kg) + external load (kg)]); 3) time under tension
(TUT) (eccentric time +milliseconds] + concentric time +milliseconds]);
and 4) total work (TW) (force [N] X displacement
[m]). The volumes differed significantly (p < 0.05) between
hypertrophy and strength in comparison with the power
protocol when VL and MDSVL were used to determine the
volume of resistance exercise completed. Furthermore, significant
differences in TUT existed between all 3 resistance
exercise protocols. The TW calculated was not significantly
different between the 3 protocols. These data imply that each
method examined results in substantially different values when
comparing various resistance exercise protocols involving
different levels of intensity.
