Linea alba response to exercise in parous women: research data from a cross-sectional study

This dataset supports the cross-sectional study titled "Immediate Effect of Four Exercises on Linea Alba Thickness, Distortion and Inter-Recti Distance in Parous Women." The study investigated the immediate biomechanical response of the abdominal wall—specifically inter-recti distance (IRD), linea alba thickness, and deformation—during four common abdominal exercises: crunch, abdominal drawing-in maneuver (ADIM), pelvic floor muscle contraction (PFMC), and the de Gasquet basic exercise.

Data include ultrasound measurements taken from 54 parous women at both supra- and infraumbilical levels. Measurements comprise IRD, linea alba thickness, and a distortion index, as well as transversus abdominis and internal oblique activation measured using simultaneous ultrasound. The dataset also contains participant metadata such as age, body mass index (BMI), number of deliveries, presence of urinary symptoms, and low back pain severity.

本数据集为一项题为《四项运动对经产女性腹白线（Linea Alba）厚度、变形及腹直肌间距（inter-recti distance, IRD）的即时影响》的横断面研究提供数据支持。该研究探究了四项常见腹部运动期间腹壁的即时生物力学响应，具体涵盖腹直肌间距（IRD）、腹白线厚度与腹壁变形情况，这四项运动分别为卷腹（crunch）、腹部内收动作（abdominal drawing-in maneuver, ADIM）、盆底肌收缩（pelvic floor muscle contraction, PFMC）以及德加斯凯基础训练（de Gasquet basic exercise）。数据集包含54名经产女性在脐上与脐下水平采集的超声测量数据，测量指标涵盖腹直肌间距、腹白线厚度、变形指数，以及通过同步超声检测得到的腹横肌与腹内斜肌激活水平。本数据集同时收录受试者的元数据，包括年龄、体重指数（body mass index, BMI）、分娩次数、尿路症状存在情况及腰痛严重程度。
