The association between the growth spurt status and risk of injury in adolescent male cricket players over a six month season
Description
This is a baseline questionnaire pre-season and a 6 month injury surveillance questionnaire dataset of adolescent male cricket players. Their growth spurt status was calculated by biological parent height and their own height and weight three times during the season. On the following dataset the longitudinal repeated Poisson regression was performed to calculate the association between growth spurt status and risk of injury.

Adolescent male cricket players 13-18 years old were invited to participate in the study, parents gave consent and players assent, after ethical clearance was received. A baseline questionnaire was filled out, thereafter a weekly injury surveillance for 22 weeks. Biological parents' height and players height and weight was used to calculate (Khamis -Roche) predicted adult height (PAH). Thereafter the % of PAH was calculated three times during the season, 2-3 months apart to establish whether players were pre-Peak Height Velocity (PHV), circa-PHV or post-PHV. Descriptive stats were performed, differences between groups by Fischer Exact and Mann Whitney. Lastly a Poisson regression analysis was performed to establish the association between growth spurt status and risk of injury during a season.
