The changes in bone markersactivity after 19 days of vibration training

The main aim of this research was determination of influence of low frequency vibrations on phosphatases (acid and alkaline) and calcium concentration in serum of subjects with osteoporosis risk. Subjects were divided into two groups: 12 subjects from experimental group performed vibration platform exercises (15 min. per day) with 3.5 Hz frequency during 19 days of experiment. Before and after experiment venous blood was taken to determine the level of researched phosphatases activity and calcium concentration. Statistical analysis showed that there was only small increase in activity of phosphatases and calcium concentration after training. In control group the calcium concentration and activity level of alkaline phosphatase was slightly decreased while acid phosphatase clearly higher
