Effect of Four Exercises on the Inter-recti Distance in Women

Overview

Diastasis rectus abdominis (DRA) is defined as an excessive separation between the two abdominal rectus muscles. It is generally quantified by the inter-recti distance. In postpartum women, the prevalence of diastasis is 60% six weeks after delivery. The increase in the inter-recti distance has been associated with a decrease in strength and endurance of the trunk flexors and rotators (p \< 0.05). Exercise during pregnancy has been shown to be helpful in the treatment of DRA. Nevertheless, there is still not strong evidence to establish what kind of exercise should be recommended during pregnancy and in postpartum. The aim of this study is to compare the morphological and functional changes of the linea alba during four exercises. Inter-recti distance, linea alba thickness and distortion index will be measured at rest, as well as during 4 exercises (draw in maneuver, crunch, pelvic floor muscle contraction and a "de Gasquet" exercise). Subgroup analysis will be performed to determine if the presence or absence of an abdominal diastasis has an influence on these outcomes. A cross-sectional pilot study will be carried out. The main outcome measure will the inter-recti distance. Secondary outcomes will be the thickness of linea alba and distortion index.
