Depression measured by Patient Health Questionnaire 9. Anxiety measured by the Generalised Anxiety Disorder 7 questionnaire. AdjR² = Adjusted R-squared value. B = non-standardised slope. β = standardised slope. SE = standard error. (M) = Male. T1 = First UK lockdown due to COVID-19 (April-May 2020). T2 = The return to competition (July-August 2020).
