The purpose of this study was to determine daily and weekly variations in vertical jump (VJ) volume and VJ height over the course of a season for female collegiate division 1 volleyball players using Vert® technology. Sixteen volleyball player’s external load was monitored through jump count, average VJ height, number of VJs completed over 20-inches, and the ratio of VJ height relative to maximum tested VJ height. The VJ parameters were compared between practices and games, and between the various position groups (outside hitters, middle blockers, libero/defensive specialist, setters). A large increase in jump count observed during pre-season, peaked at approximately 700 jumps in a week. The team completed more jumps during practices (84±63) than during games (36±32) (p < 0.05). Middle blockers (MB) averaged the greatest jump count pre-season and in-season (142±89 and 80±52) (p < 0.001). Average VJ height did not vary substantially from the mean over the 14-week season. MB maintained the highest ratio of average VJ height to maximum VJ height (p < 0.001) compared to other positions during practices and games). Understanding the external load demands of a season helps coaches, strength and conditioning coaches, and sports medicine staff better prepare athletes and reduce injury risk.
