ICCs – intraclass correlation coefficient (single measures); ICCa – intraclass correlation coefficient (average measures); CI – confidence interval; TE – typical error; CV – coefficient of variation (%); SWC – smallest worthwhile change; F
0 - theoretical maximal force; V
0 - theoretical maximal velocity; P
max - maximal power; FV slope - slope of the force–velocity relationship; RF
max - maximal ratio of horizontal-to-resultant force. D
RF - decrease in the ratio of horizontal-to-resultant force.
