Abstract AIMS the purpose of this study was to assess the effects of a supervised dance intervention based on video game choreography on isokinetic concentric and eccentric knee peak of torque (PT), quadriceps and hamstrings cross sectional area (CSA) and functionality in community-dwelling older women. METHODS Forty-seven older women were allocated in Control Group (CG, n=25) and Intervention Group (IG, n=22). The IG performed dance based on video game choreography (Dance Central, XBOX 360®, Kinect), during 12 weeks, ~40 minutes, 3x/week, without foam (1-6week) and with foam and visual disturbances (7-12 week). The pretest-training-posttest assessments included: isokinetic concentric and eccentric knee PT and CSA (Magnetic resonance imaging) of quadriceps and hamstrings and functional tests. RESULTS The light-to-moderate-intensity 12-weeks training increased 8.5% the eccentric PT of quadriceps at 60°/s (p=0.04) and 1.3% quadriceps CSA (p=0.02). CONCLUSIONS These findings suggest that dance training based on video game choreography can enhance PT and induce hypertrophy in community-dwelling older women.
