Supervised dance intervention based on video game choreography increases quadriceps cross sectional area and peak of torque in community dwelling older women

Authorship SCIMAGO INSTITUTIONS RANKINGS

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.
