Return to Sport After Childbirth: Pelvic Floor Dysfunction and Diastasis Recti Abdominis — A Narrative Review

Abstract

Background: Pregnancy and childbirth impose sustained mechanical and hormonal load on the abdominal wall and pelvic floor, frequently producing diastasis recti abdominis (DRA) and pelvic floor dysfunction (PFD) — urinary incontinence (UI), pelvic organ prolapse (POP) and anal incontinence — that may persist and complicate the return to sport.
Aim: To synthesise current medical evidence on DRA and PFD in the postpartum athlete, critically comparing their epidemiology, mechanisms, mutual relationship, conservative management and implications for return to sport.
Material and methods: Narrative review of 34 studies — systematic reviews, meta-analyses, randomised and non-randomised trials, cohort and cross-sectional studies, case reports and consensus statements — addressing postpartum DRA, PFD, physical activity and return to sport.
Results: DRA affects up to 60% of women at six weeks and about 30–33% at one year; higher parity, age and body-mass index are the most consistent risk factors. Postpartum PFD is common, UI affecting roughly one-third of women. Evidence links DRA weakly, if at all, to PFD. Pelvic floor muscle training reduces the odds of UI by about 37% and of POP; structured abdominal exercise reduces the inter-recti distance (pooled mean difference ≈ −8 mm), most when begun within three months, yet anatomical narrowing does not consistently improve function. High-impact sport is associated with stress UI even in nulliparous athletes. Return to running is best individualised, gradual and screened for pelvic-floor symptoms.
Conclusions: Return to sport after childbirth should be guided, criterion-based and multidisciplinary, integrating supervised pelvic-floor and abdominal training, symptom monitoring and realistic timelines rather than fixed dates.
