Muscular performance adaptations to short-term plyometric training on sand: influence of interday rest

Abstract

Asadi, A. (2015). Muscular performance adaptations to short-term plyometric training on sand: influence of interday rest. J. Hum. Sport Exerc., 10(3), pp.775-784. The aim of the current investigation was to determine 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.

Implementation and Efficacy of Plyometric Training: Bridging the Gap Between Practice and Research

“…The reported extent of plyometric training (1–10) in a program did not significantly differ by competition level, with 47.6, 53.3, and 29.2% of international, professional, and semiprofessional or amateur practitioners, respectively, reporting a 7 out of 10 or greater ( p = 0.38). Including the entire cohort, the average plyometric confidence level of and the extent to which survey respondents used plyometric training in programs was 7.5 ± 1.6 and 5.4 ± 2.6 out of 10, respectively.…”

“…Consensus surrounds the frequency of training with the majority of literature and practitioners reporting twice weekly for the greatest training efficiency (11). However, some authors suggest 72 over 48 hours of rest between sessions for maximal velocity, if training on sand (3). Interestingly, although quite prevalent in research, only 26% of practitioners reported using tuck jump as a common exercise.…”

The Impact of Recovery Time on Performance in Division I Collegiate Beach Volleyball Players

“…The lack of applicable studies creates difficulty in comparing the results of this study to those of others. Asadi (2) reported that a longer 9) reported reductions in counter-movement and squat jump height to below baseline for up to 96 hours after a protocol of drop jumps. These results are in contrast to those reported in this study, where the 24-hour rest time between sessions seemed to have no impact on jump performance in play, and even improved performance in the presession vertical jump test.…”

“…The lack of applicable studies creates difficulty in comparing the results of this study to those of others. Asadi (2) reported that a longer recovery period between training sessions resulted in greater improvements in jump performance for subjects who completed plyometric training. Miyama and Nosaka (9) reported reductions in counter-movement and squat jump height to below baseline for up to 96 hours after a protocol of drop jumps.…”
