Adaptations to Swimming Training in Athletes with Down's Syndrome.

Swimming training programs may help to limit declines in cardiovascular conditioning, muscle strength, mobility and social functioning in individuals with Down's Syndrome (DS): (1)

Background

This study aims to analyze the effects of a periodized swimming training program on swimming speed, lower body force and power and body composition in a group of swimmers with DS; (2)

Methods

Nine swimmers with DS (2 men and 7 women; aged 21-30 years-old) completed an 18-week periodized swimming program. The swimmers were assessed, pre and post-training, for 25 m, 50 m and 100 m freestyle swim performance, countermovement jump performance and body composition; (3)

Results

Significant and large improvements in 25 m (mean -6.39%, p < 0.05, d = 1.51), 50 m (mean -4.95%, p < 0.01, d = 2.08) and 100 m (mean -3.08%, p < 0.05, d = 1.44) freestyle performance were observed following training, with no significant changes in body composition or consistent changes in jump performance (although a large mean 14.6% decrease in relative peak force, p < 0.05, d = 1.23) (4)

Conclusions

A periodized 18-week training intervention may improve swimming performance in a small group of trained swimmers with DS, with less clear changes in jump performance or body composition. This program provides a training profile for coaches working with swimmers with DS and a platform for further research into the benefits of swimming training with this under-represented population.
