Effect of 12 weeks of yoga practice on glucose, insulin and triglycerides serum level in women with diabetes type II

Diabetes mellitus is one of the most common serious metabolic disorders. This study was done to determine the effect of 12-week yoga intervention on glucose, insulin and triglyceride serum levels in women with type II diabetes mellitus. In this clinical trial, 26 women with Type II diabetes were divided into interventional [n=16] and control groups [n=10]. Program of yoga exercise including: 75 minutes daily, three sessions in a week, and for 12 weeks. The level of glucose, insulin, leptin, HDL-C, LDL-C, triglyceride, total cholesterol were measured prior and post - training period. The levels of glucose, insulin and triglycerides in the interventional group significantly reduced compared to control group following the training period [P<0.05]. The level of leptin, HDL-C, LDL-C, total cholesterol was not significantly altered in intervention group in compare to controls. 12 weeks of yoga exercises can improve blood glucose, insulin and triglyceride in women with type II diabetes

[Influence of different intensities of resistance exercise on inflammatory markers in young healthy men]

Previous studies showed that inflammation is an important factor in the pathogenesis of atherosclerosis. IL-1beta, IL-6, and HS-CRP are biomarkers with a predictive value in cardiovascular disease. Considering that the effects of resistance training at moderate and high intensity on inflammatory markers have not been studied, the purpose of this study was to investigate the effects of resistance exercise intensities on levels of IL-1beta, IL-6, HS-CRP and fibrinogen. Thirty healthy young male volunteer students were randomly divided into 3 groups of 10 participants each. Groups I and II performed moderate [45-55% 1RM] and high intensity [80-90% 1RM] resistance exercise for 6 consecutive weeks [3 days/week] respectively. Group III, was the control group. Seven exercise stations were employed per session. The rest intervals between the sets of the protocols and stations were 1-2min and 3min respectively. Serum levels of IL-1, IL-6, HS-CRP and plasma level of fibrinogen were assessed before and after resistance training periods. Statistical analysis of data was accomplished using analysis of variance with repeated-measures design. There were no significant differences in serum levels of IL-1 and IL-6 before and after the training period. HS-CRP was decreased in groups I and II, but this was not significant [p>0.05]. Post test, however, HS-CRP in the two exercising groups was significantly lowered [p=0.008], compared to the control group. Plasma levels of fibrinogen decreased significantly in the high intensity resistance exercise group. In conclusion, short term resistance training can have beneficial effects on serum levels of some proinflammatory markers in healthy young males. In addition high intensity resistance training decreases plasma level of fibrinogen

[Effects of whey protein supplementation on hematological parameters after resistance exercise in healthy young athletes]

Physical activity causes changes in hematological parameters in athletes which finally result in cessation off their exercises, an issue that should be given attention. There is limited data available about the effects of protein supplements, containing amino acids and other useful substances, on hematological parameters of resistance to exercise in athletes. This study was carried out to investigate the effect of whey protein supplementation, after resistance to exercise in healthy athletes. In this clinical trial, changes of hematological parameters were studied after one month exercise training and whey protein supplementation in 32 healthy volunteers [16 treated cases 16 control placeboes]. Each day, whey protein supplemental 6.6 g/day] and placebo [same dose, starch] were consumed between meals, by the volunteers. Every one exercised with 80% 1RM, basically on stationary circuit principal, for one hour a day, five days a week. Before and after beginning of study, fasting blood specimens were taken and WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT and percent of white blood cells were measured separately. Statistical analyses were carried out using Student t- test and paired t-test [SPSS version 15]. Levels of WBC, RBC, HGB, HCT, PLT, MCHC in two groups significantly [P<0.05] decreased, but there was no difference between two groups. MCV increased in the groups, but again there was no difference between them. MCH and percent of lymphocytes were unchanged in both groups. In the supplement group, the percentages of the neutrophils and other white blood cells showed no significant changes, but in the placebo group, there were significantly increased and decreased, respectively. However there was no significant difference between the two groups in the percentage of white blood cells, separately. The present study showed that one month of Whey protein supplementation with 6.6 g/day is ineffective on hematological parameters changes after resistance to exercise. Further studies, with different dosages and longer periods of time are recommended
