Do stronger abdominal muscles help knee stability and prevent injury?

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
