Weighted Vest in Obesity Trial
Daily standing and stepping time appeared to modify hip bone responses during dietary weight loss in a randomized trial
A secondary analysis of the 12-month INVEST in Bone Health trial revealed that greater upright time in older adults with obesity impacted hip bone mineral density differently based on whether they wore a weighted vest. Community-dwelling adults aged 60 to 85 were assigned to weight loss alone, weight loss with resistance training, or weight loss with a weighted vest, following a structured diet aiming for a 10% weight reduction. While a 30-minute increase in upright time correlated with decreased hip bone density in the weight-loss-only group, the resistance training and vest groups showed no significant change. This research could imply that appropriate mechanical loading plays a crucial role in bone adaptation during weight loss.
1. Greater upright time linked to hip bone density changes. 2. Participants were older adults with obesity or overweight. 3. Three study groups: weight loss only, resistance training, weighted vest. 4. Upright time influenced hip density in weight-loss-only group. 5. 30-min increase corresponded to decreased bone density. 6. Highlighted need for mechanical loading in bone health. 7. Further studies needed on upright time and vest use.
