purpose of this research was to compare effect 3 different rest intervals
on the squat volume completed during a workout. Twenty college-aged
men volunteered to participate in this study (age 20.73 ± 2.60 years;
body mass 80.73 ± 10.80 kg). All subjects performed 3 testing sessions,
during which 4 sets of the squat was performed with 85% of a 1RM load.
During each testing session, the squat was performed with a 1, 2,
or 5-minute rest interval between sets. Volume was defined as the
total number of repetitions completed over 4 sets for each rest condition.
Statistical analysis was conducted separately for the squat. One-way
repeated analyses of variance with Bonferroni post hocs demonstrated
significant differences between each rest condition for both exercises
tested (p < 0.05). The 5-minute rest condition resulted in the
highest volume completed, followed in descending order by the 2- and
1-minute rest conditions. The ability to perform a higher volume of
training with a given load may stimulate greater strength adaptations.
