The effect of swimming program on body composition levels in adolescents with Down syndrome

Background Down syndrome has been associated with more than 80 clinical characteristics such as diabetes, cardiovascular problems or obesity. Aims The current study determined the effect of a 36 weeks swimming program on different indicators of body composition in adolescents with Down syndrome. Methods and procedures outcomes 45 adolescents with Down syndrome were recruited and randomized to two groups (control group vs. exercise group). Adolescents allocated in the control group carried out a recreational swimming program twice a week during 36 weeks meanwhile adolescents allocated in the exercise group did exercise three time a week during 36 weeks. BMI, Waist circumference, waist-to-height ratio, triceps, subscapular, suprailiac and thigh skinfold were measured. Results ANCOVA tests were used to evaluate differences between groups in post-test intervention. Repeated measures of ANOVA were performed in order to assess differences in pre-test intervention in each group. t test were carried out to compare the pre-post-intervention differences in physical characteristics and body composition within each group. The exercise group had significant improvements in all variables of body composition (p < 0.05) except in subscapular and thigh skinfold. Conclusions and implications The results suggest that a 36 weeks swimming program consisting of 3 sessions of 50 minutes is able to decrease levels of body composition in a sample of adolescents with Down syndrome. The findings indicate that it would be important to generate high intensity sports programs in sports associations in order to obtain positive impact on body composition levels within this population.
