Mean (SD), baseline (BDC) and post 14-day bed rest (BR14) of anthropometric parameters in young and older adults

|---|---|---|---|---|---|---|
| BDC | BR14 | p | BDC | BR14 | p | |
| Mass (kg) | 74.8 (8.8) | 71.6 (8.3) | <0.001 | 79.9 (12.3) | 77.5 (11.7) | <0.001 |

Comparison of mass, height, BMI, TBW, FFM, FM and MM between baseline and intervention levels was done with Student t test for dependent variables (paired t test). An alpha level of 0.05 was set for test to indicate significance. No significant differences at baseline and after intervention were observed between groups (independent t test)
