Feasibility of a hip flexion feedback system for controlling exercise intensity and tibia axial peak accelerations during treadmill walking

The ability to meet high exercise intensities is limited by the increased risk of injury in some clinical populations. Previous studies have linked large tibia peak positive accelerations resulting from running developing lower-extremity injury. purpose this study determine feasibility using a hip flexion feedback system (HFFS) and maintain different while maintaining low axial accelerations. Ten healthy participants were tested on HFFS test an independent walking/running 40% 60% heart rate reserve (HRR). During test, controlled real time intensity directing individuals specific maximum targets during walking providing visual information that assists them initial contact phase. Maximum are calculated based real-time readings participant’s rate. was independently participant treadmill speed. Compared at HRR resulted similar heart-rate error but lower No differences observed for intensity. This paper describes novel approach uses individual’s calculate maximal individual should walking. also provides acceleration cues. Therefore, can increase control In particular, might be alternative strategy moderate vigorous populations injuries.
