*Mean±SD for test 1 (season 1), mean interseason difference and ICC with 95% CI, and measurement error (SEM and MDC) from test 1 (season 1) to test 2 (season 2) are reported.
†Expressed in the same unit as the measurement (9+ points).
‡Significant at p<0.05 (paired t-test).
ICC, intraclass correlation coefficient;
MDC, minimal detectable change; SEM, SE of measurement.
