How is the phase angle associated with total and regional bone mineral density in university athletes? *
Objective. To investigate how phase angle (PhA) is associated with total and regional bone mineral
density (BMD) (femur and lumbar spine) in university athletes. Approach. This cross-sectional study
was conducted in Florian ópolis, Brazil, with 167 university athletes from different sports (92
males). The PhA was obtained through electrical bioimpedance and BMD was obtained through dual x-ray
absorptiometry (DXA). Data on the covariables age, time involved in the sport, type of sport (low,
medium and high impact), daily use of oral contraceptives, and vitamin D calcium and/or protein
supplementation were obtained through anamnesis, while fat mass and fat- and bone-free mass were
obtained through DXA. Simple linear regression and a 5% significance level were used. Main results .
In female athletes, PhA was directly associated with total BMD ( β : 2.20; 95% CI: 0.43; 3.96) and
BMD in the femur ( β 0.85; 95% CI: −0.23; 1.94) and lumbar spine ( β ...
