The purpose of this investigation was to study the effects of and compare two interval weight training programs with two different recovery times (Long-term and short-term) on some muscular functions (anaerobic power, force, strength and endurance) in high school students of Esfahan who were randomly assigned
to either long-term or short-term interval weight training group, respectively.
Before and after 12 weeks of training, the subjects were tested by a series of
specific experiments. The subjects in each groups carried out the same special
interval weight-training program (Delorm-Watkins method), three times a week for 12 weeks. However, the recovery periods between sets of training were
different. Group 1 and Group 2 experienced 160 second and 40 seconds rest
between sets of training respectively. The pretest post-test difference analyses for
dependent variables indicated significant improvement in muscular force and
anaerobic power of legs and muscular force of dominant leg in Group 1 (long rest) (P
The results showed greater improvement for subjects in Group 1 (long rest) compared to subjects in Group 2 (short test).
