| Abstract |
| Down syndrome is the most common chromosomal disorder and is characterized by distinct neurodevelopmental and physical health challenges that affect growth, motor competence, and metabolic balance. Individuals with Down syndrome often present with hypotonia, ligamentous laxity, and delayed motor development, which influence their capacity to acquire and maintain functional movement patterns. ). Exercise interventions, particularly aerobic and resistance training, have been shown to be safe and beneficial for individuals with Down syndrome when properly prescribed. This quasi-experimental study employed a posttest–one- year follow-up design. Pretest and posttest data were extracted from the initial research (six weeks of aerobic and resistance training)data were collected one year after the end of the intervention, without any organized exercise program during that period. The statistical population included boys with Down syndrome aged 7 to 14 years in Tehran.In this one-year follow-up study, changes in body mass index and perceptual–motor performance of boys with Down syndrome were evaluated one year after completing a six-week exercise intervention. The purpose of this study was to examine the long-term sustainability of improvements in body mass index (BMI) and perceptual–motor performance in boys with Down syndrome following a six-week program of aerobic and resistance training, evaluated after one year of detraining.The results demonstrated a significant increase in BMI across all groups over the follow-up period, alongside a decline in gross and fine motor skills and upper-limb coordination. Importantly, the resistance training group showed a relatively smaller decline in motor performance compared to the aerobic group, suggesting that neuromuscular adaptations may be more resilient than cardiorespiratory gains, although they too diminished over time. |
