The aim of this study was to compare the peak values of ground reaction forces before and after fatigue in women with a history of COVID-19 and healthy women during walking.</span></span></span></span></span></span></span><br>

People with the history of COVID-19 had a positive Polymerase Chain Reaction (PCR) test during the disease engagement. Bertec force plate with a sampling rate of 1000 Hz was used to record the ground reaction force data during walking. Data were analyzed using independent two-sample t-test.</span></span></span></span></span></span></span><br>

However, the values of pre- and post-test mean differences of lateral ground reaction forces approach a significant level (p=0.055) with a high effect size value (d=0.83).</span></span></span></span></span></span></span><br>
