“…Mechanical vibrations produced by OVP can be transmitted to the whole body; when an individual is on the base of the platform that is turned on, generating whole body vibration (WBV) exercise [ 17 – 19 ]. WBV is well known as an alternative exercise modality for enhancing balance and flexibility [ 20 ], muscle activity, force and power [ 21 – 23 ], and improvement in bone mineral density [ 24 , 25 ]. Some authors [ 15 , 26 , 27 ] have discussed that the effects of the WBV exercises would be related to alteration on the plasma concentration of biochemical markers.…”

The consequences of treatment involving the use of a natural product and whole body vibration (WBV) exercise have been investigated. The aim of the present study was to evaluate the effects of the joint treatment with an aqueous extract of Chenopodium ambrosioides and WBV on physiological parameters in rats. Wistar rats (n=20) were divided equally into four groups: control group (CG), treated with C. ambrosioides (CHE) group, exposed to 50 Hz of mechanial vibration (VBR), and treated with C. ambrosioides and exposed to 50 Hz of mechanical vibration (VBR + CHE) daily for 6 weeks. The body mass of the animals was determined weekly, the feed intake and the stool consistency were measured daily. One day after the 6 weeks of treatment, samples of blood were collected and used for biochemical analysis. Along 6 weeks, there was an increase (P<0.001) in the feed intake in VBR group and a decrease in the CHE group in comparison with other groups. The levels of the enzyme aspartate aminotransferase (AST) in VBR + CHE group decreased (P<0.05) in comparison with other groups. No differences were found in body mass and stool consistency. WBV altered the feed intake without directly affecting the body mass. Moreover, WBV in association with C. ambrosioides caused alteration in the enzymatic activity of AST.

“…WBV may influence muscular function, i.e., muscle contraction and relaxation, as well as bone properties, because WBV of 50–60 Hz was reported to strengthen extensors and flexors of the knee [31,32]. Therefore, in this study, it seems likely that WBV at 45 and 60 Hz induce an increase in strain magnitude/rate and muscle contraction cycles, and thereby positively influence trabecular bone mass and TBMS parameters.…”

“…Second, we did not measure dynamic strain in the tibia. Such a strain could have been estimated by measuring the strain magnitude or strain rate in the tibia [17,21,23,25,26,28,29,31]. Third, we have examined TBMS parameters, but not cortical bone geometry.…”

ObjectivesTo examine the effects of whole body vibration (WBV) on bone properties in growing rats, and to explore the optimal conditions for enhancing bone properties.MethodsThirty-six 4-week-old male rats were divided into 1 control and 5 experimental groups. Each experimental group underwent WBV at 15, 30, 45, 60, and 90 Hz (0.5 g, 15 min/d, 5 d/wk) for 8 weeks. We measured bone size, muscle weight and bone mechanical strength of the right tibia. Trabecular bone mass and trabecular bone microstructure (TBMS) of the left tibia were analyzed by micro-computed tomography. Serum levels of bone formation/resorption markers were also measured.ResultsWBV at 45 Hz and 60 Hz tended to enhance trabecular bone mass and TBMS parameters. However, there was no difference in maximum load of tibias among all groups. Serum levels of bone resorption marker were significantly higher in the 45-Hz WBV group than in the control group.ConclusionsWBV at 45–60 Hz may offer a potent modality for increasing bone mass during the period of rapid growth. Further studies are needed to explore the optimal WBV conditions for increasing peak bone mass and TBMS parameters. WBV modality may be a potent strategy for primary prevention against osteoporosis.

This study aimed to investigate the effect of dental caries and the subsequent poor oral health on the blood parameters and anaerobic performance of athletes. The study was conducted on 30 elite rowing athletes (18 male and 12 female) who had a DMF-T index value of 3.9 after an oral check-up. The athletes were split into two groups: the study group, which consisted of athletes having four or more infected tooth; and the control group with athletes having one or no infected tooth. The study group consisted of 15 athletes (9 male and 6 female) with infected tooth number ≥4, DMF-T value of 7, and a mean age of 18.73 ± 1.05 years, whereas the control group consisted of also 15 athletes (9 male and 6 female) with DMF-T value of 0.9 and a mean age of 18.26 ± 2.01 years. The anaerobic capacity of athletes was measured using the Wingate test (WanT). The two demographically similar groups had no difference in their blood parameters and urine density values (P > 0.05). Also, no statistically significant difference in the WanT results was observed between the two groups, and WanT performances were similar in both groups (P > 0.05). Further, the superficial decay at the enamel and dentine levels did not negatively impact the anaerobic performance of athletes. On the contrary, it was suggested that studies should be conducted on the effect of severe dental caries at the pulpal level on athletic performance, which may also cause chronic inflammation.
