The study aimed to examine the concurrent validity of player self-reported and independently observed throwing volume, and to investigate the influence of sex, playing position, and time to upload self-reported data on the accuracy of self-reported throwing loads. The findings showed a moderate positive correlation between self-reported and observed throwing loads, but most players reported values with significant error. Therefore, the accuracy of self-reported throwing load needs to be re-evaluated.
Objectives: To determine the concurrent validity of player self-reported and independently observed throwing volume. Examine whether sex, playing position, or time to upload self-reported data post training influences the accuracy of self-reported throwing loads. Design: Cross-sectional cohort study. Methods: A total of 8 female and 18 male elite cricket players participated in the study. Overarm throws from 12 training sessions during the 2020-21 cricket year were observed. Player self-reported throwing volume data were retrieved post training, with the time difference between session completion and self-reported data upload recorded. Results: A moderate positive correlation was found between self-reported and observed throwing loads (rho = 0.65), however only 22 % of players reported values within a 10 % level of error. Players reported a mean (SD) absolute inaccuracy of 11.17 (9.77) throws, and a mean (SD) relative inaccuracy of 24.76 (16.04) percent. Sex did not influence reporting accuracy (p = 0.41). Females tended to upload self-reported data the day of training, whereasmen report the day following. Playerswho uploaded their data greater than one day after trainingwere the most inaccurate with a mean relative inaccuracy of 36 %. Conclusions: While there is a clear relationship between observed and self-reported throwing volumes, the findings of this study question the validity of using player self-reported throwing load as a marker of true throwing loads with most players recording in excess of 10 % error. High performance staff and players should consider whether the current accuracy of self-reported throwing load justifies the additional reporting burden on the players during training.
