The primary outcome was the overall injury prevalence over a 16-week period, measured at 2 weekly intervals with the Oslo Sports and Trauma Research Centre questionnaire. Estimates for the primary outcome and associated 95\% CIs were obtained using generalised estimating equation models. Secondary outcome scores included prevalence of substantial injuries, overall incidence, adherence and time-loss injuries.Results A total of 579 (83\%) (TennisReady n=286, control n=293) participants were included in the primary analysis. The mean injury prevalence was 37\% (95\% CI 33\% to 42\%) in the TennisReady vs 38\% (95\% CI 34\% to 42\%) in the control group (adjusted p-value 0.93). The prevalence of substantial injuries was 11\% (95\% CI 9\% to 14\%) in the TennisReady vs 12\% (95\% CI 9\% to 15\%) in the control group (p value of 0.79). Analysis of the secondary outcome scores showed no difference between groups. The mean prevalence rates between high (8\%) and low (92\%) adherent groups were 32\% (95\% CI 23\% to 44\%) and 37\% (95\% CI 33\% to 42\%), respectively (p value 0.36).Conclusion Providing an unsupervised e-health tennis-specific exercise programme did not reduce the injury rates and should not be implemented.Trial registration number NTR6443.}, issn = {0306-3674}, URL = {https://bjsm.bmj.com/content/54/17/1036}, eprint = {https://bjsm.bmj.com/content/54/17/1036.full.pdf}, journal = {British Journal of Sports Medicine} }
