Do stronger abdominal muscles help knee stability and prevent injury?

Investigation of Core Neuromuscular Performance as a Determinant of Knee Stability and Injury Prevention in Young Female Athletes Using Vicon 3D Motion Capture and Functional Performance Tests

Not applicable Interventional European University of Madrid · NCT07499973

This trial will test whether an 8-week core stabilization program improves abdominal endurance and knee stability in physically active women aged 18 to 35.

What this trial studies

Physically active women aged 18–35 will complete baseline testing of abdominal endurance and knee stability using the Prone Bridge Test, Lateral Squat Down, Y-Balance Test, and Drop Vertical Jump recorded with a Vicon motion-capture system. Participants will then follow an 8-week supervised core stabilization program that includes front planks, side planks, and Nordic hamstring exercises while a control condition is maintained for comparison. Researchers will compare pre- and post-intervention measurements to identify changes in abdominal strength and biomechanical markers of knee stability. Outcomes focus on changes in prone bridge time and performance on balance and jump tasks as captured by motion analysis.

Who should consider this trial

Good fit: Women aged 18–35 who perform at least 6 hours of regular physical activity per week and can complete the required physical tests are ideal candidates.

Not a fit: Men, people older than 35, those with current lower-limb or spinal injuries, pregnant individuals, or those already engaged in structured core training are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the program could increase abdominal endurance and knee stability, which may reduce the risk of knee injuries in active young women.

How similar studies have performed: Previous research shows mixed but sometimes positive effects of core-strengthening programs on balance and lower-limb injury risk, so the approach has some supporting evidence but is not definitively proven.
