Narrative objectives1

This study aims to investigate the effects of a once-weekly, 2-month BONE exercise program on bone health, peripheral circulation, and glycation-related indices in community-dwelling older women. All participants will initially undergo a 2-month control period and will then be randomly assigned to two groups with different intervention start times using a wait-list controlled design. The effect of the BONE program will be evaluated by comparing the early-start group with the delayed-start group during the same study period. All participants will ultimately receive the BONE intervention, allowing additional within-participant comparisons between control and intervention periods. Bone health will be assessed using lumbar spine bone mineral density measured by REMS and ultrasound-based bone parameters of the radius. Peripheral circulation will be assessed using estimated hemoglobin levels, vessel width, VOI, and finger surface temperature measured by ASTRIM FIT. Glycation-related indices will be assessed using the AGE Scanner.

Primary outcomes

Change in lumbar spine bone mineral density assessed by radiofrequency echographic multi-spectrometry (REMS) using the EchoS system. The change from month 2 to month 4 during the BONE intervention period in the early-start group will be compared with the change during the corresponding wait-list control period in the delayed-start group.

Key secondary outcomes

1. Changes in ultrasound-based bone parameters of the radius.
2. Changes in estimated hemoglobin levels measured by ASTRIM FIT.
3. Changes in vessel width measured by ASTRIM FIT.
4. Changes in VOI measured by ASTRIM FIT.
5. Changes in finger surface temperature measured by ASTRIM FIT.
6. Changes in AGE accumulation-related indices assessed using the AGE Scanner.
7. Changes in each outcome from immediately before to after the 2-month BONE intervention in all participants.
8. Within-participant comparison of changes during a 2-month control period and a 2-month BONE intervention period in all participants.
9. Changes in study outcomes during the 2-month post-intervention follow-up period in the early-start group.

Interventions/Control_1

Participants will continue their usual daily activities without the BONE program during the initial 2-month control period. Following randomization at month 2, participants will receive the BONE exercise program once weekly for 2 months, from month 2 to month 4. They will subsequently undergo a 2-month post-intervention follow-up period from month 4 to month 6. Assessments will be performed at baseline and at months 2, 4, and 6.

Interventions/Control_2

Participants will continue their usual daily activities without the BONE program during the initial 4-month wait-list control period. Following randomization at month 2, participants will remain on the wait-list for an additional 2 months and will then receive the BONE exercise program once weekly for 2 months, from month 4 to month 6. Assessments will be performed at baseline and at months 2, 4, and 6.
