The Influence of Low-Frequency Vibrations on the Lipid Profile in Women

Abstract

Introduction: The aim of this dissertation is an evaluation of the effect of low frequency vibration on serum lipid profiling women. Materials and Methods: A group of females aged 28-64 years old were assessed twice, before and after 19 days of exposure to low frequency vibration. The parameters of the vibration used (frequency and amplitude) and the short exposition time were selected in order to comply with standards established to safeguard human health; mechanical stimulus safe for human health according to the Polish Standard PN EN ISO 2631-1:1997. The parameters used were as follows: frequency 3.5Hz, amplitude 4 mm and duration time 20 min. The main exclusion criteria for this study were: neoplasm, history of myocardial infarction, history of stroke, history of bone fracture within the two years prior to the study. To assess the effect of low frequency vibration with the parameters as specified above the following physiological and biochemical variables were used: total cholesterol serum level, high density lipoprotein (HDL) cholesterol serum level, low density lipoprotein (LDL) cholesterol serum level, triglycerides (TGD) serum level. Biochemical blood parameters were assessed before and after the trial. Friedawald’s formula was used for the assessment of LDL cholesterol serum level. Upon completion of the study and the subsequent analysis of the results obtained the following conclusions were formulated. Results: A statistically significant lowering of total serum cholesterol and LDL serum cholesterol was observed. Conclusions: The use of the vibration platform with the operational parameters specified had a beneficial effect on the variables measured.
