Strength versus aerobic program: effects on body composition and health-related physical fitness levels of youths with Down syndrome.

To determine the effect of a 16-week fitness program (strength vs. aerobic) on different indicators of body composition and components of health-related physical fitness in youths with Down syndrome. Fifty adolescents (19 girls and 31 boys; average age, 18.33 ± 1.42 years) with Down syndrome were recruited and randomized to two groups (strength group vs. aerobic group). Adolescents allocated in the aerobic group carried out a physical activity program three times a week for 16 weeks meanwhile adolescents allocated in the strength group performed a fitness program three times a week for 16 weeks. The exercise group had significant improvements in all health-related physical fitness variables ( < .05) but not on body composition. A sixteen week fitness program consisting of three sessions of 60 min is able to increase levels of health-related physical fitness but not on body composition in youths with Down syndrome. The aerobic program does not seem to show significant differences.
