The aim of this investigation was to determine the effectiveness of rating of perceived exertion (RPE) scale to measure plyometric exercise intensity during low (L), moderate (M) and high (H) intensity. Fourteen physically active students (age; 21±1.1 y, height; 178.7±8.2 cm and body mass; 74.6±9.1 kg) volunteered to participate in this study and performed each intensity once separated with 24 h recovery. The H consisted of 1 set of 5 repetitions at 90% of the subject’s vertical jump height (VJH). The M consisted of 10 repetitions at 70% VJT, and the L consisted of 1 set of 15 repetitions at 50% VJH. RPE was measured following the completion each intensity using 0-10 Borg RPE scale. Data was analyzed using repeated measures ANOVA and the level of significant was set at p < 0.05. The results indicated increases in RPE following enhancing exercise intensity (p < 0.05). Performing fewer repetitions at a higher intensity was perceived to be more difficult than performing more repetitions at a lower intensity. The results of the current investigation revealed that the RPE method is effective in monitoring different plyometric exercise and training intensities and it can be recommend that strength and conditioning professionals and athletes use the RPE method based on the effectiveness tool for monitoring their plyometric exercise and training sessions at different intensities.

The purpose of this study was to examine the effects of short-term plyometric depth jump training on sand interposed with 48 hours or 72 hours of rest between training sessions on power type muscular adaptations in recreationally physical active men. Fifteen collegiate physical active men, who were familiar with plyometric exercise, participated in this study and were randomly divided into 2 groups: plyometric training with 48 h (PT48, N=7) and 72 h (PT72, N=8) of rest between training sessions. Pre and post training on sand, participants were measured in vertical jump (VJ), standing long jump (SLJ), agility t Test (TT), 20 and 40 m sprints, and one repetition maximum leg press (1RMLP). The plyometric training program on sand was applied during 6 weeks, 2 sessions per week, with 5 sets of 20 repetitions depth jump exercise from 45 cm box height. After completing 6 weeks training period, the PT48 and PT72 groups showed significant improvement in all performance tests (p<0.05), with statistically significant differences between treatments in TT and 40 m sprint time. With regard to significant differences in TT and 40 m sprint for PT72 compared with PT48 and greater improvements for PT72 in all tests, it can be recommend that coaches, strength and conditioning professionals apply 72 h rest between plyometric training sessions when sand surface was used.
