Abstract

Weight loss therapy to improve health in obese older adults is controversial because it causes further bone loss. Therefore, it is recommended that weight loss therapy should include an intervention such as exercise training (ET) to minimize bone loss. The purpose of this study was to determine the independent and combined effects of weight loss and ET on bone metabolism in relation to bone mineral density (BMD) in obese older adults. One-hundred-seven older (age >65 years) obese (body mass index [BMI] ≥30 kg/m2) adults were randomly assigned to a control group, diet group, exercise group, and diet-exercise group for 1 year. Body weight decreased in the diet (−9.6%) and diet-exercise (−9.4%) groups, not in the exercise (−1%) and control (−0.2%) groups (between-group p < 0.001). However, despite comparable weight loss, bone loss at the total hip was relatively less in the diet-exercise group (−1.1%) than in the diet group (−2.6%), whereas BMD increased in the exercise group (1.5%) (between-group p < 0.001). Serum C-terminal telopeptide (CTX) and osteocalcin concentrations increased in the diet group (31% and 24%, respectively), whereas they decreased in the exercise group (−13% and −15%, respectively) (between-group p < 0.001). In contrast, similar to the control group, serum CTX and osteocalcin concentrations did not change in the diet-exercise group. Serum procollagen propeptide concentrations decreased in the exercise group (−15%) compared with the diet group (9%) (p = 0.04). Serum leptin and estradiol concentrations decreased in the diet (−25% and −15%, respectively) and diet-exercise (−38% and −13%, respectively) groups, not in the exercise and control groups (between-group p = 0.001). Multivariate analyses revealed that changes in lean body mass (β = 0.33), serum osteocalcin (β = −0.24), and one-repetition maximum (1-RM) strength (β = 0.23) were independent predictors of changes in hip BMD (all p < 0.05). In conclusion, the addition of ET to weight loss therapy among obese older adults prevents weight loss–induced increase in bone turnover and attenuates weight loss–induced reduction in hip BMD despite weight loss–induced decrease in bone-active hormones. © 2011 American Society for Bone and Mineral Research

  • Exercise training during calorie restriction prevents increases in bone turnover and serum sclerostin, thereby minimizing bone loss.

    “Studies emphasize exercise training during calorie restriction to prevent an increase in bone turn-over327 and an increase in serum levels of sclerostin328, thus minimizing bone loss.”
  • Multicomponent exercise training that included PRT of moderate-to-vigorous intensity prevented the increase in bone turnover and attenuated the decrease in hip BMD in frail older adults with obesity engaged in a weight loss intervention.

    “Moreover, multicomponent exercise training that included PRT of moderate-to-vigorous intensity prevented the increase in bone turnover and attenuated the decrease in hip BMD in frail older adults with obesity engaged in a weight loss intervention [306].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
