Sex-linked differences in equilibrium reactions among adolescents performing complex sensorimotor tasks.

摘要: Abstract Equilibrium reactions were compared between male and female adolescents (prepuberal puberal), classified into two groups: those who had previously learned complex motor tasks (dance or acrobatics) with no particular training. Subjects stood (eyes open eyes closed) on a free seesaw platform, the displacements of which calculated from accelerometer measures. They instructed to maintain vertical position their frontal plane either parallel (to measure antero-posterior oscillations) perpendicular axis platform lateral oscillations). Girls better stability than boys as shown by smaller center gravity. Untrained subjects, irrespective sex, least stable. trained in acrobatics more stable dancers. Differences related sex can be attenuated physical training involving equilibrium exercises suggests that moderate sustained could reduce incidence falls aged persons professionally exposed workers.
