The objective of this study is to determine the effect of rocker running shoes on the biomechanics of the of the lower limb compared to other rocker shoes in experienced long-distance runners.
Conditions
Interventions
Group 1: Subject will perform running on the laboratory floor at 3.3 m/s. Also treadmill running will be performed for level (at 3.3 m/s), 24% (=13.5°) uphill (at 2.2 m/s) and 24% downhill (at 4.4 m/s

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcomes are kinetic, kinematic and ground reaction force data from the lower extremity. The kinematics of the lower extremities are derived from 3d optoelectronic motion capture and anthropometrical measurements. For this measurements, markers, which reflect the infrared light emitted by the motion tracking cameras, will be placed on defined anatomical landmarks. 3d positions of the markers in space are reconstructed from the 2-D images from 12 motion tracking cameras. From those positions 3d joint kinematics will be calculated (Vicon Nexus Software V2.6 and Matlab 2017a). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes are muscle activation from the right gluteus maximus (GMax) and medius (GMed). Surface electromyography (EMG) system (myon AG, Schwarzenbach, CHE) are used to record activity measuring of the right GMax and GMed at 1000 Hz. | — |
