Ground reaction force during walking with and without counterbalance load system

The purpose of this study was to determine the ground reaction force (GRF) during walking with and without counterbalance load system. Peck GRF was recorded with force plate while walking with different conditions on the treadmill. Twenty-six students (age was 22.41±1.75 years) attended three test s...

Peck GRF was recorded with force plate while walking with different conditions on the treadmill. Twenty-six students (age was 22.41±1.75 years) attended three test sections in three days apart. Participants after 10 min warm up walked 10 min on the treadmill without any backpack in the first day.
