The effect of Dynamic Acute Stretching Versus Warm-Up Exercises on Knee Range of Motion and Quadriceps Length in Young Adults with Quadriceps Tightness: A Randomized Controlled Trial

Methodology: We conducted a study where young adults with tight quadriceps muscles were randomly assigned to two groups: one group performed dynamic stretching, while the other engaged in warm-up exercises. We assessed their knee bending ability, quadriceps muscle length, and quality of life over a four- week period, and analyzed the results using specialized statistical methods. Results: Both groups showed improvements in knee bending and muscle flexibility after four weeks of training.

However, the group that practiced dynamic stretching exhibited greater enhancements in knee bending and quadriceps muscle length than the warm-up exercise group. This suggests that dynamic acute stretching is more effective than warm-up exercises for improving knee movement and muscle flexibility in young adults with tight quadriceps muscles.
