COMPARISON OF THE EFFECTS OF WALKING AND BENCH-STEP EXERCISE ON OSTEOCALCIN AND CTX-1 IN POST-MENOPAUSAL WOMEN WITH OSTEOPENIA

Abstract

Purpose: Bench-step exercise produces biomechanical movements beneficial to improve bone remodeling. However, no studies have confirmed the effects of bench-step exercise (BE) on bone formation and resorption. The goal of this study is to compare the effects of bench-step and walking exercise (WE) on changes in osteocalcin and CTX-1 levels. Methods: Fifty-nine sedentary post-menopausal women with osteopenia (T-score between [Formula: see text]1 and [Formula: see text]2.5) were randomly divided into two groups: WE group ([Formula: see text]) and BE group ([Formula: see text]). Subjects performed 12 weeks of exercise. The osteocalcin and CTX-1 levels were analyzed using enzyme-linked immunosorbent assay. Independent [Formula: see text]-test or Wilcoxon test was used to analyze the osteocalcin and CTX-1 levels. The difference in changes in the osteocalcin and CTX-1 between the groups before and after was analyzed using Mann–Whitney test. Results: The results showed a significant increase in the osteocalcin and CTX-1 levels in both groups ([Formula: see text]). The increased levels of osteocalcin between groups were not statistically different ([Formula: see text]). The increase in CTX-1 resulting from BE was lower than that from WE ([Formula: see text]). Conclusion: This study indicates that BE may inhibit resorption stronger than WE.
