Acute effects of static stretching on peak and end-range hamstring-to-quadriceps functional ratios

Figure 1 The two types of static stretching exercise for the quadriceps muscle (A in standing and B in sitting position).

Figure 2 The two types of static stretching exercise for the hamstring muscle (A in standing and B in sitting position).

Figure 3 Changes in percentage (%) following stretching intervention for peak and end range torque measurements of the quadriceps muscle (A) and the hamstring muscle (B). Ecc: Eccentric; Con: Concentric; ERE: End-range of knee extension; 60: 60°/s angular velocity; 180: 180°/s angular velocity. (^aP < 0.05, ^bP < 0.01, ^cP < 0.001).

Figure 4 Changes in percentage (%) following stretching intervention for functional hamstring-to-quadriceps muscle strength ratios for knee extension during entire and end range of motion. ER: End range; 60: 60°/s angular velocity; 180: 180°/s angular velocity.
