The impact of high BMI on acute changes in body composition following 90 minutes of running.

ABSTRACT:

Objectives

Although physical activity ameliorates the metabolic impact of high body mass index (BMI), runners with BMI≥25 kg/m² are relatively understudied.This study had two goals: 1) Identify differences in body composition, as measured by dual X-ray absorptiometry (DXA), between overweight (BMI≥25 kg/m²) runners (OWR) and normal weight (BMI<25 kg/m²) runners (NWR) and 2) Examine whether an 90 minute run alters total or regional fat mass, as measured by DXA, in OWR and NWR. We hypothesized that OWR would have higher total body fat than NWR and OWR with greater changes in visceral fat after a prolonged run.

Design

Body composition analysis before and after a supervised run.

Methods

We recruited NWR (n=16,F:n=7,28.1±1.4 years, BMI 22.0
