Resumen
Background: This study aims to assess the effects of 8 weeks of plyometric jump training
(PJT) conducted on sand or a rigid court surface on jump-related biomechanical variables and
physical fitness in female indoor volleyball players. Methods: Seventeen participants were randomly
divided into a sand surface group (SsG, n = 8) and rigid surface group (RsG, n = 9). Both groups
completed equal indoor volleyball training routines. Participants were assessed pre and post the
8-week PJT for jump-related biomechanical variables (countermovement jump (CMJ) RSI; drop jump
(DJ) reactive strength index (RSI); spike jump (SJ) height; CMJ height; CMJ rate of force development
(RFD); CMJ velocity at take-off; DJ height and CMJ peak force), 20 m linear sprint time, t test for
change-of-direction sprint (CODs) time, Wingate test peak power (PP), cardiorespiratory endurance,
and leg-press one-repetition maximum (1RM). Results: A two-way mixed analysis of variance
(group × time) revealed that there was a significant group × time interaction between DJ height
(p = 0.035) and CMJ peak force (p = 0.032) in favour of RsG and SsG, respectively. A significant
interaction was also observed for cardiorespiratory endurance (p = 0.01) and 1RM (p = 0.002), both
favouring the SsG. No other group × time interaction was observed. Conclusions: The type of surface
used during PJT induced specific adaptations in terms of jump-related biomechanical variables and
physical fitness in female indoor volleyball players. Based on the individual needs of the athletes,
practitioners may prescribe one type of surface preferentially over another to maximize the benefits
derived from PJT.
