Effect of Coronavirus 19 on Maintaining Balance in Skilled Athletes.

Abstract

Preliminary studies have reported that motor control is negatively impacted following an infection of COVID-19. The purpose of this study was to evaluate the effect of COVID-19 on maintaining balance in highly skilled athletes. As part of a larger investigation that was initiated in 2019, twelve professional handball players were recruited to participate in a study that was designed to measure static balance performance. Following the initial pre-test, six participants (body height 184.8 ± 4.7 cm; body weight 85.5 ± 3.3 kg; age 21.3 ± 1.2 years) were infected with COVID-19. The remaining six participants (body height 188.7 ± 2.6 cm; body weight 92.3 ± 3.7 kg; age 26.3 ± 3.3 years) never tested positive for COVID-19 and were presumably not infected with the virus. The experimental design required all the participants to complete an initial balance assessment (pre-test) and a later balance assessment (post-test). To fully analyze our data, we conducted a 2 (condition: COVID, no-COVID) X 2 (test: pre-test, post-test) ANOVA with repeated measures on the second factor. Our analysis revealed that the skilled athletes who contracted COVID-19 had a significant decrease in balance performance from the pre-test that occurred prior to being infected with COVID-19 relative to the post-test that occurred following the COVID-19 infection. Additionally, the skilled athletes who were not infected with COVID-19 did not demonstrate the same deterioration in balance performance in the same period. This study highlights the impact COVID-19 has on static balance performance in a group of highly skilled handball players. Longitudinal studies are needed to fully understand the lasting impacts COVID-19 has on motor behavior.
