ABSTRACT Background and aim: Whole body vibration training can improve muscular force by affecting neuromuscular system and mechanical mechanisms. The aim of this study was to investigate the effect of an 8 week whole body vibration training (WBVT) on neuromuscular performance in healthy elderly women. Materials and Methods: Based on an experimental and BOSCO training protocol, thirty elderly female women (50±5.5 yrs old) were selected and divided randomly into two experimental and control groups. Before and after vibration training, timed Up & Go and 5-chair stand tests were performed to evaluate neuromuscular performance in elderly women. Data were processed with SPSS software version 18 and one way ANOVA test was used for data analysis. P<0.05 was considered significant. Results: Data analysis showed that there was a significant improvement in neuromuscular performance in WBVT group compared to control group (P ≤ 0.05). Conclusion: Based on the results of this study WBVT can reduce the possibility of falling risk among old women by improving neuromuscular performance.

Background and Aim: Whole-body vibration training as an exercise method and as a non-drug treatment strategy has been used for improvement of cardiovascular fitness. The aim of this study was to examine the effect of whole-body vibration training on vo2max, body fat percentage, and lipid profile and serotonin level in elderly veterans. Material and Method: In this semi experimental study, forty veterans with 25 percent damage (age range 55-65 years of age) were selected and randomly divided into two experimental and control groups. Subjects in the experimental group performed whole-body vibration training for a period of 12 weeks with frequency of 30-35 Hz and amplitude of 1/7 mm. Our control group did not participate in any regular exercise program during study period. Serotonin levels, VO2max, percentage of body fat, BMI and lipid profile were measured before and after training for both groups. Data were introduced into SPSS18 software and analyzed by t-tests at P<0/05. Result: After 12 weeks of whole body vibration training, we found significant decrease in the percentage of body fat, BMI and lipid profile and significant increase in VO2maxand serotonin in the experimental group (P<0.05). Conclusion: Whole-body vibration training in the elderly veterans as a new training method can lead to improved cardiovascular function.

Bckground and Aim: Strenuous endurance activities induce oxidative stress and influences important tissues such as kidney and lung. The purpose of this study was to investigate the effects of curcumin supplementation on glutathione peroxidase (GPX) activity and malondialdehyde (MDA) level in the kidney and lung tissues during 8 weeks of strenuous endurance training in male wistar rats.
Material and Method: In this experimental study, after one-week familiarization, 28 male Wistar rats (weight= 256.11±19.24 g, age= 8 weeks), were randomly divided into; Control (n=6), Curcumin (n=6), Endurance (n=8) and Endurance + curcumin (n=8) groups. Endurance training  was carried out 5 sessions per week for 8 weeks by using an animal treadmill. The speed and duration of running increased to 35 m/min and 70 min in the last week. The animals received intraperitoneal injections of curcumin supplement 30 mg/kg, 3 times per week for 8 weeks. GPX activity and MDA levels were measured in the kidney and lung tissues by spectrophotometric method. Data were analyzed by one way ANOVA test.
Results: There were no significant differences in GPX enzyme activity in the kidney (p=0.077) and lung (p=0.114) tissues between the groups. However, MDA levels in the kidney (p=0.029) and lung (p=0.037) tissues in endurance training group were significantly higher than those in the endurance+curcumin group.
Conclusion: It seems that strenuous endurance training in spite of inducing lipid peroxidation, can not disturb final line of antioxidant defense in the kidney and lung tissues. Also, strenuous endurance training induces oxidative stress in the kidney and lung tissues and curcumin supplementation can prevent oxidative stress
