Table 1.

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

Young (N = 7) Older adults (N = 16)
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
BMI (kg/m2) 24.0 (2.4) 22.9 (2.1) <0.001 26.6 (4.4) 25.8 (4.1) <0.001
TBW (l) 44.6 (2.8) 41.2 (2.8) 0.005 46.0 (6.3) 43.1 (4.8) <0.001
FFM (kg) 60.9 (3.8) 56.3 (3.9) 0.004 61.8 (9.1) 58.0 (7.2) <0.001
FM (kg) 14.0 (6.2) 15.3 (7.0) 0.170 18.1 (6.1) 19.5 (7.0) 0.049
MM (kg) 42.5 (3.4) 39.0 (3.2) 0.021 39.8 (6.8) 37.5 (4.8) 0.007

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)
