Comparison of Isolated or Combined Static Stretching and Foam Rolling on Knee Extensors’ Function

Static stretching (SS), foam rolling (FR), and a combination of both are used as warm-ups for sports training. However, no reports have compared or examined the warm-up effects short-term interventions (i.e., 30-s). Therefore, this study was designed to compare examine SS, FR, SS+FR on knee extensors. The dominant extensors 14 male university students (22.0 ± 1.3 years old) were tested. Five conditions randomized: 60-s 30-s SS+ FR differences in intervention method, duration, combined. measures flexion range motion (ROM), pain pressure threshold (PPT), tissue hardness, maximum voluntary contraction-isometric (MVC-ISO), MVC-concentric (MVC-CON) torques, measured before after intervention. Knee ROM (d = 0.40, d 0.59, 0.54, 0.52 respectively) PPT 0.77, 0.60, 0.90, 0.74, 0.52, significantly increased (p < 0.01), hardness -0.79, -0.63, -0.53, -0.59, -0.72, decreased 0.01) all conditions. MVC-ISO SS but did not affect MVC-CON results revealed that exercise effective increasing ROM, PPT, decreasing hardness. with more than muscle strength, so is recommended when goal increase while maintaining torques. Similarly, can eliminate effect strength impairments.
