Correlation coefficients (r) (90% Confidence Intervals; CI), explained variance and interpreted strength of relationships between peak force (rPF) for the countermovement jump (CMJ), squat jump (SJ) and isometric mid-thigh pull (IMTP), and; thickness of the lateral gastrocnemius (LG) and vastus lateralis (VL), and pennation angle VL.
