Measurements (mean ± SEM) before and after three dynamic stretching exercises.
(A) The passive straight-leg raising (PSLR). (B) Maximal eccentric isokinetic strength (ECC). (C) Angle of peak torque (APT). CON: jogging only; DS: dynamic open kinetic chain stretching; LEC: dynamic closed kinetic chain stretching. * Significant (P< 0.05) difference from the Pre-value. # Significant (P< 0.05) difference from the CON group. + Significant (P< 0.05) difference from the DS group.
