Brief Summary

This controlled, quasi-experimental clinical trial investigated the effects of a combined Pilates and whole-body vibration (WBV) intervention on bone mineral density (BMD), muscle strength, postural balance, and quality of life in postmenopausal women. Fifteen women aged 50-71 years initially served as a historical control group in a previous study. After completion of that protocol, ten of these participants underwent a 26-week combined intervention consisting of supervised Pilates exercises and WBV performed three times per week. BMD was assessed using dual-energy X-ray absorptiometry (DXA). Peak torque of the lower limbs was measured by isokinetic dynamometry. Postural balance was evaluated using a force platform, and quality of life was assessed using the Short Form-36 (SF-36) questionnaire. Outcomes obtained after the combined intervention were compared with those from the historical control phase.

Study Arms (1)

Pilates plus WBV

EXPERIMENTAL

Pilates exercises combined with whole-body vibration.

Other: Pilates plus whole-body vibration

Interventions

Pilates plus whole-body vibration OTHER

The intervention consisted of a combined protocol integrating supervised mat-based Pilates exercises with whole-body vibration (WBV) performed on a side-alternating vibrating platform. Sessions were conducted three times per week for 26 weeks. Each session included structured Pilates exercises targeting core stability, postural alignment, and lower-limb strengthening, immediately followed by WBV exposure with controlled frequency and amplitude parameters. This combined protocol differs from previous interventions conducted in the same population, in which Pilates and WBV were applied separately. The present study specifically investigated the potential additive or synergistic effects of simultaneously implementing both modalities within the same training session, which had not been previously examined in this cohort.

Model Details: This study was designed as a single-group interventional trial with comparison to a historical control phase. Participants previously enrolled as a control group in an earlier study underwent a 26-week combined intervention consisting of supervised Pilates exercises and whole-body vibration (WBV), performed three times per week. Outcomes obtained after the combined intervention were compared with data collected during the prior control period, in which participants did not receive structured exercise intervention. The combined intervention phase was conducted after completion of the original protocol and was implemented to investigate the potential additive effects of Pilates and WBV.
