Bone mineral density in apparently healthy men at baseline and after 6 and 12 months of RT or JUMP [1]
| Group | RT (n=19) | JUMP (n=19) | ||
|---|---|---|---|---|
| Time (mo) | 0 | 12 | 0 | 12 |
| BMD(g/cm2) | ||||
| WB* | 1.132 (0.081) | 1.137 (0.085) | 1.114 (0.071) | 1.119 (0.071) |
| TH** | 0.898 (0.082)b | 0.906 (0.089)a | 0.912 (0.116) | 0.907 (0.111) |
| LS* | 0.939 (0.069) | 0.955 (0.088) | 0.919 (0.056) | 0.928 (0.049) |
Data are means (S.D.)
WB, whole body. TH, total hip. LS, lumbar spine.
Significant time main effect for WB BMD [mean (SD), 95% CI. 0 mo: 1.123b (0.076), 1.098–1.148; 12 mo: 1.128a (0.078), 1.102–1.154 g/cm2; time main effect, p<0.05] and LS BMD [0 mo: 0.929b (0.069), 0.906–0.952; 12 mo: 0.941a (0.072), 0.918–0.965 g/cm2; time main effect, p<0.001]. Post hoc within group comparisons were not performed for WB or LS BMD as there were no significant time-by-group interactions.
Significant time-by-group interaction for TH BMD [mean (SD), 95% CI. RT 0 mo: 0.898b (0.082), 0.851–0.945; 12 mo: 0.906a (0.089), 0.860–0.953 g/cm2; time-by-group interaction, p<0.1].
Means with different letter superscripts are significantly different.
