Objective: The purpose of this study was to examined the kinematic relationship and differences through the range of motion (ROM),muscle activity, and vertical ground reaction force (VGRF) during forward and backward lunge movements, which are effective inimproving muscle strength and balance ability of the lower extremities, and to provide clinical information on more efficient lungemovements. Design: Cross-sectional studyMethods: Fifteen adult males who met the selection criteria were tested for their dominant feet.Forward and backward lunges werethen performed, and the ROM, muscle activity, and VGRF were measured for kinematic analysis during the lunge movement.Thedifferences betweenthe forward lunge and backward lunge intervention were examined using a paired t-test. Results: A significant increase in the ROM of the knee and ankle was observed during the forward and backward lunges (p<0.05). In addition, in terms of the muscle activity, the peak values of the vastus medialis oblique (VMO) and VGRF also showed a significant increase in the forward lunge compared to the backward lunge (p<0.05). Conclusions: This study showed an increase in VGRF peak value, knee and ankle ROM, and VMO muscle activity duringforward lunge. Based on these results, it is considered necessary to apply differently depending on the direction of progress inconsideration of the musculoskeletal situation and physical ability during the lunge movement.
