Core area muscles are considered as connecting portion of the body, between upper and lower extremities. So, it has an important role in sufficient and optimum function of total body. These muscles role and importance are well addressed in previous studies. Consisting evidence show that lack of core stability may be associated with lower limb injury. However, effects of core muscles weakness or fatigue on walking or running is less in focus of study. The aim of this study was to assess the effect of core muscles fatigue on progression angle during walking and running.
twenty healthy female (age=19.75 years, height=161/75 cm, mass=58.98 kg) participated in this study. Participants were asked to walk barefoot with self-selected speed on a footscan mounted in middle of a 17 m walkway. Also, it was asked to they run barefoot in 3.3 m.s-1 on the footscan. After this session, participants performed 7-stiotionary core muscles fatigue protocol. After fatiguing protocol, participants performed post-test similar to pre-test session.
The results of this study showed that after core muscles fatigue, walking progression angle was decreased. In addition, core muscles fatigue decreased progression angle during running.
According to the results of this study, it could be concluded that fatigue or weakness of core muscles fatigue can alter progression angle during walking or running. These changes could be informative to the clinicians that they considere these muscles in their rehabilitation programs or for running coaches to account these muscles strengthening in their routine exercises.
