Effects of aerobic exercise on thyroid hormonal change responses among adolescents with intellectual disabilities

Abstract

ObjectiveWe aimed to investigate the impact of a 16-week aerobic exercise programme on the changes in the plasma level concentration of thyroid hormones in adolescents with intellectual disabilities.MethodologyUsing purposive sampling, a total of 36 adolescents with intellectual disabilities were selected to participate in the study. The training programme consisted of 16 weeks of moderate-intensity aerobic exercises at an intensity of 45–75 hours. These exercises were performed in three sessions a week, and each session took 30–45 min: 10 min warm-up, 15–30 min main aerobic workout and 5 min cool-down exercises. The plasma levels of triiodothyronine (T3) and tetraiodothyronine (T4) and of thyroid stimulating hormone were measured before and after 16 weeks of aerobic exercise intervention.ResultsAfter 16 weeks of intervention, a significant change was observed in the plasma level concentration of thyroid (T3 and T4) and thyroid stimulating hormones (p<0.05) in the group treated with aerobic exercise.ConclusionWe concluded that aerobic exercise had an impact on the change in the plasma level concentration of thyroid and thyroid stimulating hormones in adolescents with intellectual disabilities.
