Due to their high workload and unfavorable working position, young female dentists are particularly at risk of cardiometabolic diseases and an early reduction in bone mineral density (BMD). With focus on the latter issue, short bouts of resistance exercise with high strain magnitude and velocity are commonly considered to be a feasible option to prevent bone loss in the early years of young adulthood. In parallel, whole-body electromyostimulation (WB-EMS) a trainings technology able address all main muscle groups simultaneously, however with dedicated exercise intensity might be a time-effective, joint friendly and safe option to maintain BMD in people unable or unmotivated to exercise conventionally. In the present study, we aim to compare the effects of a single session of WB-EMS versus high intensity, high velocity resistance exercise on biomarkers of bone formation (Procollagen type 1 N propeptide, P1NP) and resorption (C-terminal telopeptide of type I collagen, CTX-I). We hypothesize that no clinically relevant different effects on P1NP and CTX-I were determined.
