Effects of Dynamic Acute Stretching vs. Warm-Up Exercises on Range of Motion, Quality of Life, and Quadriceps Length Among Young Adults with Quadriceps Stiffness: A Randomized Controlled Trial

Author(s) Vivek Shahu
Country India
Abstract Background: The quadriceps muscle frequently becomes tight, often resulting in reduced knee joint mobility and decreased functional performance in young adults. Healthcare professionals commonly recommend stretching and warm-up exercises to enhance flexibility and joint movements.
Objective: This study aimed to determine whether dynamic acute stretching or traditional warm-up exercises are more effective at improving the knee range of motion, quadriceps muscle length, and overall quality of life in young adults with tight quadriceps muscles.
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.
