The Effects of Whole Body Vibration Training on Some Biochemical Values in Terms of Osteoporosis Risk in Premenopausal Women

Nurcan Demirel, Fatih Kaya, Salih Pınar


The main purpose of the present study is to comparatively examine the effects of Whole body vibration (WBV) trainings on some biochemical bone-turnover markers (Beta-CTx, Osteocalcin) in terms of osteoporosis. Twenty-four sedentary women (mean age=37.12±1.84 years) participated in the study. The participants were randomly divided to 3 groups: whole body vibration exercise group (WBV, n=8), classical resistance exercise group (CR, n=8), and control group (CO, n=8). Vibration trainings and classical resistance trainings were applied in similar exercise models for major muscle groups three days a week for eight weeks, not on consecutive days but in the same contexts. Of biochemical values, Beta-CTx and Osteocalcin were analysed by using Cobas e 411 ECLIA (Electro Chem. Luminance Immune Assay) method before and after the eight-week exercise period. For intra-group comparisons paired-samples t-test, for inter-group comparisons one way ANOVA, and for multi-comparisons Tukey test were used. While a statistically significant difference was found between pretest posttest of Beta-CTx and Osteocalcin values of CR (p<.05), there was not a significant difference in WBV and CO groups (p>.05). A statistically significant difference was found between the groups in terms of pretest posttest biochemical value changes (Beta-CTx, Osteocalsin) of the participants (p<.05). As a result, eight-week WBV training in premenopausal women can be considered as safe in terms of biochemical values’ (Beta-CTx, Osteocalcin) remaining unchanged. On the other hand, CR training made significant changes on the values in question. Whether this change is an acute effect or not has become a raising question. This case can be studied in premenopausal women in further research.
