Purpose Exercise-related gastrointestinal complaints are frequently reported in young athletes; however, evidence regarding the effects of resistance-based training modalities on bowel habits is limited. The aim of this study was to investigate the effect of an 8-week TRX program on bowel habits and gastrointestinal system of male child swimmers.
Methods Thirty-two prepubertal male swimmers aged 9-13 years were voluntarily enrolled in the study. Participants were randomly allocated to either the TRX or control group. Both groups were evaluated using the Bristol Stool Scale and a questionnaire assessing defecation habits before and after the 8-week TRX exercise program.
