Efeito agudo dos alongamentos passivo estático e ativo dinâmico na amplitude de movimento de dorsiflexão em praticantes de ginástica aeróbica esportiva

Abstract

Sports Aerobic Gymnastics is a modality that combines aerobics, acrobatic sports and rhythmic gymnastics elements with music, dance and choreography. It is required of the practitioners to have good flexibility to continuously execute complex and high-intensity movement patterns. In this sense, this study compared the acute effect of passive static and active dynamic stretching on dorsiflexion range of motion (ROM) in sports aerobic gymnastics athletes. Twenty-four female sports aerobics practitioners were evaluated, randomly allocated into 3 groups: static passive stretching (n=8), dynamic active stretching (n=8) and control (n=8). The experimental protocol consisted of measuring by goniometry the dorsiflexion ROM of the left ankle before and after applying different stretching techniques. Regarding the control group, no intervention was performed. ANOVA test was used to assess diferences on the dorsiflexion range of motion between the groups, with significance level set at p < 0,05. Results indicated a significant increase in dorsiflexion ROM in the static passive (p < 0,05) and dynamic active (p < 0,05) groups, with no difference in the intergroup comparison (p = 0,52). Therefore, static passive and dynamic active stretching showed similar acute results in increasing dorsiflexion ROM in a group of practioners of sports aerobic gymnastics.
