“…Segmentation masks were generated in the T1 images and registered to the quantitative Dixon FF images as described by (Chaudry et al, 2020). This method has been successfully applied in other studies (Chaudry et al, 2020;Engelke et al, 2020;Ghasemikaram et al, 2021). Based on the histogram of the FF values of all voxels of the intra fascia volume, a threshold was determined to separate IMAT from MT.…”

“…"Muscle quality" might be an adequate candidate for this approach. Although there is an ongoing debate as to which parameters characterize muscle quality (MQ), fatty muscle infiltration as assessed by magnetic resonance imaging (MRI) applying enhanced segmentation and automated quantification software may well be a reliable and clinically relevant morphometric predictor of MQ (Chaudry et al, 2020;Engelke et al, 2020). In the present study, we thus aimed to determine the effect of once weekly 20 min WB-EMS on fatty muscle infiltration at the mid-thigh in moderately active men 18-70 years old.…”

Once Weekly Whole-Body Electromyostimulation Enhances Muscle Quality in Men: Data of the Randomized Controlled Franconian Electromyostimulation and Golf Study

Whole-body electromyostimulation (WB-EMS) is commercially advertised as a time-efficient resistance-type exercise technology. Indeed, the commercial, non-medical setting applies 20 min of WB-EMS only once a week. However, this setting conflicts with the approved scientific approach of higher training frequencies. Using data from an ongoing study on WB-EMS and golf performance as a vehicle, we evaluate the effect of once weekly WB-EMS on changes of fatty muscle infiltration, as a crucial parameter of muscle quality. Fifty-four moderately physically active male amateur golfers 18–70 years old were randomly allocated to a WB-EMS (n = 27) with a standard setting of once weekly 20 min and a non-WB-EMS control group (CG, n = 27). Intermuscular adipose tissue (IMAT) volume and intrafascial muscle tissue (MT) volume per unit of intrafascial volume as determined by magnetic resonance imaging were used to characterize muscle quality. Intention to treat analysis with multiple imputation was applied. WB-EMS was conducted at the participants’ homes; thus, the attendance rate was close to 100%. After 16 weeks of intervention, we observed increases in volume-adjusted IMAT (p = 0.040) and decreases in MT (p = 0.206) in the CG. IMAT decreased in the WB-EMS group (p = 0.215), while MT increased significantly (p = 0.032). Of importance, group difference (i.e., “effects”) for intra-group changes in volume-adjusted IMAT (effect size: d´ = 0.66; p = 0.028) and MT (d´ = 0.70; p = 0.020) was significant for both parameters. Once weekly WB-EMS application significantly affects muscle quality of the mid-thigh in moderately active, healthy men 18–70 years old.
