Comparing the effects of hopping and strength-balance exercises on the selected muscles strength and balance in male athletes with chronic ankle instability

Background and Aims: The present study aims to compare the effects of two types of hopping and strength-balance exercises on the balance and strength of selected muscles in athletes with chronic ankle instability.Methods: Participants were 30 male athletes with chronic ankle instability, who were selected using a purposive sampling method and randomly divided into two groups of hopping and strength-balance exercise. A questionnaire was used to record demographic characteristics and the information about the history of sports. To measure strength, a dynamometer was used. The Standing stork test and Y balance test were used to measure static and dynamic balances, respectively. Analysis of covariance and the Least Significant Difference post hoc test were used to compare the means.Results: There was a significant difference in the static balance (P<0.001) and the total dynamic balance between the two groups (P
