The effect of fatigue due to exhausting running on static and dynamic balance in women with hyperlordosis

Hyperlordosis is one of the spinal abnormalities. The aim of this study was to investigate the effect of fatigue caused by strenuous running on static and dynamic balance in women with hyperlordosis.

In the present quasi-experimental study, 30 women with lumbar spine curvature greater than 40 degrees were included in the experimental control groups. To measure lumbar lordosis from a flexible ruler and to assess static and dynamic balance, displacement changes and center of pressure (COP) distance, with the eyes open on a hard surface using a biodex device in two pre-fatigue conditions (3 repetitions) and after fatigue (3 repetitions) were performed. The experimental group was affected only by the independent variable of muscle fatigue. Simon test was used to perform the fatigue program to the point of exhaustion.

Fatigue due to running to the point of exhaustion had a significant effect on static and dynamic balance (COP displacement). Fatigue with Simon protocol in the difficult directions of dynamic balance test (anterior, anterior-external and external) compared to before the fatigue protocol had a significant difference in dynamic balance on the subjects.

According to the results, it can be said that fatigue reduces balance in women with lumbar hyperlordosis by reducing postural control.
