ABSTRACT
Flavonoids consider as a large group of plant metabolites that 6,000 types of them have been identified till now. In some studies, it has been shown that they can increase aerobic performance and maximal oxygen consumption [VO[2] max].The aim of this study was to evaluate the effect of anthocyanin [as one of the most important kind of flavonoids] supplementation on body composition, exercise performance and muscle damage indices in athletes. This double-blinded clinical trial involved 54 female and male athletes at Isfahan University of Medical Sciences with athletic history of at least 3 years. Body composition, exercise performance, creatine kinase, and lactate dehydrogenase were assessed. Individuals were selected by simple sampling method, they divided into two groups using permuted block randomization method. First group received 100 mg anthocyanin pills, and the second group received 100 mg placebo pills, daily for 6 weeks. Participants asked to continue their routine diet and physical activity during the study period, and they were followed through phone calls or text messages. Soft lean mass, total body water and percent body fat were not changed significantly in the anthocyanin group after intervention but VO[2] max increased significantly in the anthocyanin group [48.65 +/- 4.73 vs. 52.62 +/- 5.04] [P

This study was to evaluate the effect of a period of aquatic exercise therapy on muscle strength, joints range of motion and the factor VIII coagulant in hemophilia patients. This was a semiexperimental, pretest, post-test study with a control group. This semi-experimental study comprised twenty men suffering moderate hemophilia were selected by convenience sampling method from patients of a referral hospital. They were randomly assigned to intervention and control groups of equal number. The hemophilia patients who were referred to Sayedo-Shohada Hospital enrolled in this study. Twenty men suffering moderate hemophilia were selected using convenience sampling method and then divided randomly into intervention and control groups [10 patients in each group]. Subjects of aquatic exercise therapy group underwent activity in water in three sessions [45-60 minutes] per week for 8 weeks, while the control group was only under follow-up and during this period did not experience any effective physical activity. The patients' muscle strength and joint range of motion were evaluated through standard laboratory tools, using an isokinetic dynamometer [Biodex, Systems III] and a standard goniometer in the beginning and at end of the study. Finally, data was analyzed using analysis of covariance [ANCOVA]. The strength of the muscles around the knee joint [to perform extension and flexion movements] increased significantly in the case group while the control group experienced a significant reduction of strength in left leg, but in right leg remarkable change was observed. Range of motion in all joints was improved in the case group, while the control group did not improve significantly. The results showed that aquatic exercise therapy can be a useful method to improve joints' strength and range of motion in hemophilia patients in order to improve their daily functioning and quality of life
ABSTRACT
The prevalence of anemia in pregnancy is nearly 8% in the first quarter, 12% in the second quarter and 29% in the third quarter based on hemoglobin levels. The purpose of this study was to examine the influence of a selected aerobic exercise period on hemoglobin, hematocrit, and red blood cells count in pregnant women after delivery. This Study was a quasi-experimental. From all women who were referred to the maternity unit of the clinic in Shahreza, 40 inactive pregnant women in second trimester aged 20-35 years were selected and then randomly divided in two experimental [n=20] and control [n = 20] groups. The women in the experimental group had selected aerobic exercise under an experienced instructor for 8 weeks [three sessions of 45 minutes per week with the intensity of 40-75 percent of maximum heart rate reserve], while the control group was only followed up. Blood hemoglobin, and hematocrit levels and also red blood cells count were measured before and after exercise in both groups. A significant improvement were observed in the blood hemoglobin and hematocrit levels and also the number of red blood cells in the women of the experimental group following 8 weeks exercise with compared to the baseline levels of those variables and also to the control group [P<0.01]. Unlike the control group, the experimental group showed an increase in blood hemoglobin and hematocrit levels and also number of red blood cells [P<0.05]. Our findings indicate that the selected aerobic exercise program is an effective and safe method in reducing disease of anemia in pregnant women in second trimester
