Exclusion criteria: • Smoking • Type 2 Diabetes Mellitus • Any back/leg/knee/neck/postural complaints

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the amount of muscle mass that is lost following 2 weeks of bed rest and whether BFR can be applied to effectively preserve muscle mass and strength during bed rest. | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess differences in muscle fiber cross-sectional area (CSA), satellite cell content/activation, muscle fiber vascularization, muscle protein synthesis rates between both legs (BFR vs control), muscle strength, whole-body fat mass, adipose tissue gene expression and oral glucose tolerance before and after 2 weeks of bed rest. | — |
