Effects of running speed and foot strike pattern on knee ligament loading

Basic Information

Recruitment status	Pending
Health condition(s) or Problem(s) studied	Healthy adults
Date of first enrollment	2026/08/01
Target sample size	20
Countries of recruitment	Japan
Study type	Interventional
Intervention(s)	Participants will perform running trials under different running speed conditions (2.5 m/s, 3.5 m/s, and 4.5 m/s) and foot strike pattern conditions (rearfoot strike, midfoot strike, and forefoot strike) in a laboratory equipped with a three-dimensional motion capture system and force plates. Running biomechanics will be assessed using a motion capture system, force plates, and photocells. Lower-extremity kinematic and kinetic data will be collected during running. Outcome measures will include peak vertical ground reaction force, peak knee extension moment, knee flexion angle, knee valgus moment, knee valgus angle, and hip adduction angle. These variables will be compared across running speed and foot strike conditions.

Outcome(s)

Primary Outcome	Primary Outcome Measures Peak vertical ground reaction force Peak knee extension moment Knee flexion angle Knee valgus moment Knee valgus angle Hip adduction angle These variables will be measured using a three-dimensional motion analysis system and force plates during running and will be compared across different running speeds and foot strike patterns.
Secondary Outcome	Peak vertical ground reaction force Knee flexion angle Knee valgus moment Knee valgus angle Hip adduction angle These variables will be measured using a three-dimensional motion analysis system and force plates during running and will be compared across different running speeds and foot strike patterns.
