This study evaluated the change in blood oxidative stress, blood interleukin-2, and physical performance following 6 weeks of moderate intensity and duration aerobic dance exercise in 24 sedentary women. Blood samples were collected at rest twice before (baseline) and after the 6-week intervention for analysis of protein hydroperoxide (PrOOH), malondialdehyde (MDA), total anti-oxidant capacity (TAC), and interleukin-2 (IL-2) levels. Maximal treadmill run time (Time(max)) and maximal oxygen consumption (VO(2max)) were also measured. All variables were statistically analyzed with a repeated measurement ANOVA and Tukey post hoc. No differences were noted in any variable during the baseline period (p > 0.05). After aerobic dance exercise, VO(2max), Time(max), TAC and IL-2 were significantly increased, whereas MDA levels were decreased significantly (p < 0.05). PrOOH did not change either between baseline measures or after exercise. It can be concluded that aerobic dance exercise at a moderate intensity and duration can improve physical fitness, decrease MDA, and increase TAC and IL-2 in previously sedentary women.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to assess the effects of aerobic dance exercise on body composition in sedentary overweight women. In this study, Total 55 adult sedentary women participated as volunteers. The age, height and weight averages of the subjects exercise and control group were respectively 35,10±9,12 years, 1,60±5,22 m and 68,55±6,73 kg (n=29) and 30,27±10,85 years, 1,59±5,53 cm and 61,25±8,38 kg (n=26). Body composition (via skinfolds caliper), waist hip ratio, waist circumference were measured and body fat percentage, Basal Metabolic Rate and Lean Body Mass were calculated at sedentary women. The measurements were taken twice as before and after aerobic-dance exercise being applied an 8-week series of one hour exercise three days per week. The control group did not participate in any physical activity during the six-week period. There were significant differences between pretest and posttest for weight, body mass index, waist circumference, waist hip ratio, metabolic and body composition parameters in exercise group (p<0,05). Besides there were significantly decreased body weight, Lean Body Mass, Basal Metabolic Rate and fat percentage (p<0,05). Furthermore, there were not significant differences between pretest and posttest for waist circumference, waist hip ratio, body composition parameters, Lean Body Mass, Basal Metabolic Rate, body weight and body fat percentage in control group(p>0,05). As a result, it can be say that aerobic dance exercise at a moderate intensity and duration can improve physical fitness and can decrease body fat percentage, Lean Body Mass and Basal Metabolic Rate during weight loss.
[Show abstract][Hide abstract] ABSTRACT: Leptin is the product of the ob gene and circulates as a 16 kDa protein hormone. High-sensitivity C-reactive protein (hs-CRP) is known to be a sensitive marker of inflammation and cardiovascular risk factor and malondialdehyde (MDA) is a direct marker of oxidative stress and naturally occurring product of lipid peroxidation. The resting serum leptin, hs-CRP and MDA levels of elite adolescent soccer players and physically active adolescents were investigated. Eighteen elite adolescent soccer players aged 14.3 +/- 0.3 years and eighteen physically active subjects aged 14.6 +/- 0.4 years participated in the study. Resting serum leptin levels were not different, but hs-CRP and MDA levels were higher in adolescent elite soccer players compared to physically active adolescents. Therefore, participation in prolonged soccer training increased resting serum hs-CRP and MDA levels but had no effect on resting serum leptin compared to participation in sports activities/classes in adolescents.

[Show abstract][Hide abstract] ABSTRACT: Oxidative stress (OS), a state characterized by an imbalance between pro-oxidant molecules including reactive oxygen and nitrogen species, and antioxidant defenses, has been identified to play a key role in the pathogenesis of subfertility in both males and females. The adverse effects of OS on sperm quality and functions have been well documented. In females, on the other hand, the impact of OS on oocytes and reproductive functions remains unclear. This imbalance between pro-oxidants and antioxidants can lead to a number of reproductive diseases such as endometriosis, polycystic ovary syndrome (PCOS), and unexplained infertility. Pregnancy complications such as spontaneous abortion, recurrent pregnancy loss, and preeclampsia, can also develop in response to OS. Studies have shown that extremes of body weight and lifestyle factors such as cigarette smoking, alcohol use, and recreational drug use can promote excess free radical production, which could affect fertility. Exposures to environmental pollutants are of increasing concern, as they too have been found to trigger oxidative states, possibly contributing to female infertility. This article will review the currently available literature on the roles of reactive species and OS in both normal and abnormal reproductive physiological processes. Antioxidant supplementation may be effective in controlling the production of ROS and continues to be explored as a potential strategy to overcome reproductive disorders associated with infertility. However, investigations conducted to date have been through animal or in vitro studies, which have produced largely conflicting results. The impact of OS on assisted reproductive techniques (ART) will be addressed, in addition to the possible benefits of antioxidant supplementation of ART culture media to increase the likelihood for ART success. Future randomized controlled clinical trials on humans are necessary to elucidate the precise mechanisms through which OS affects female reproductive abilities, and will facilitate further explorations of the possible benefits of antioxidants to treat infertility.
