Description
Summary:Jump monitoring has become an essential procedure for training load management and injury prevention inmany sports, such as beach volleyball. This study aimed to assess the validity of WIMU PROTM devices for jump detectionin beach volleyball and to determine, in a preliminary way, whether gender, the players individuality or the technicalaction associated with the jump could influence data accuracy. Eleven beach volleyball players (6 female and 5 male) wererecorded with high-definition cameras and the WIMU PROTM device during 42 one-set official matches. The number ofjumps recorded by the device was compared with the observational analysis. The instruments sensitivity was calculatedbased on true positives and false positives/negatives in terms of gender, player individuality, and the type of the jump.The WIMU PROTM device presented great sensitivity (96.29%), with a lower gender difference (male = 97.20%, female= 94.56%) and higher inter-player variability in females (91.06%–98.08%) than males (95.02%–98.40%). Regardingthe type of the jump, actions classified as “Others” (99.10 %) obtained the greatest sensitivity, followed by “Block” (97.25%), “Spike” (95.75 %) and “Serve” (94.69 %). The WIMU PROTM is a valid device for automatic jump detection inbeach volleyball. The variations observed in terms of gender, players individuality, and the type of the jump highlightthe importance of a context-specific individualized algorithm adjustment.
