Recreational physical exercise in the water is predominantly based on aerobic metabolism. Since it involves both carbohydrate and lipid sources of energy, aqua aerobics has a beneficial effect on metabolism of these substrates. The aim of the study was to assess the impact of a 3 month aqua aerobics training program on the metabolic profile of women with abdominal obesity. The study sample comprised 32 women aged 41-72 years. Somatic characteristics and variables characterizing carbohydrate and lipid metabolism were measured before the commencement and after the completion of the training program. During the 2nd measurement all mean anthropometric variables were found to be significantly lower (p<0.01). In the blood lipid profile, the concentrations of total cholesterol, LDL-cholesterol and HOMAIR were significantly lower (p<0.01). Furthermore, the levels of fasting triglycerides, glucose and insulin were reduced significantly (p<0.05) after the training program. The aqua aerobics program contributed to positive changes in lipid metabolism, anthropometric variables, as well as the fasting insulin, glucose levels and insulin resistance index in women with abdominal obesity.

Mechanical stress is considered to be essential for the regulation of bone mass. The purpose of this study was to determine whether treadmill exercise at moderate intensity induces alterations in blood osteocalcin concentration in rats. Male Wistar rats, aged 5 months, were divided randomly into two groups: trained animals (n = 6) and controls (n = 7). Trained rats were exercised 5 days/week for 4 weeks on a motor-driven treadmill. Each exercise session lasted 60 minutes and the average locomotion speed was 16.2 m/min. After completion of the training period, a blood sample was taken for osteocalcin measurement and the hindlimbs medial gastrocnemius muscles were excised and weighed. Comparative analysis showed significantly lower circulating osteocalcin levels in the exercised rats in comparison to control animals. It is possible that the observed decreased blood osteocalcin concentration is transient in nature. Factors including stress may also influenced the results.Serum osteocalcin concentration in treadmill-trained rats

This study investigated the effects of supplementation with Krill oil on levels of pro-oxidant/antioxidant balance markers and levels of pro-inflammatory cytokines in professional rowers submitted to exhaustive exercise.This double-blind study included 17 members of the Polish National Rowing Team. Subjects were randomly assigned a supplemented group (n=9) which received two capsules (500 mg) of Krill oil daily for 6 weeks, or a placebo group (n=8). At the beginning and at the end of preparatory camp, subjects performed a 2000 m maximum effort test on a rowing ergometer. Blood samples were taken from the antecubital vein prior to each exercise test, 1 minute after completing the test, and after 24-hours of rest. The following redox parameters were assessed in erythrocytes: superoxide dismutase (SOD), glutathione peroxidase (GPx), and thiobarbituric acid reactive substances (TBARS) concentration. Additionally, creatine kinase (CK) activity was measured in plasma samples, while tumor necrosis factor (TNF-α) concentrations were measured in the serum.Exercise significantly increased values of SOD, TNF-α and TBARS in both groups, but recovery levels of TBARS were significantly lower in athletes receiving Krill oil compared with the control group.Based on these results we conclude that supplementation with Krill oil (1 g per day) in trained rowers diminished post exercise oxidative damage to erythrocytes during recovery, but had no effect on antioxidant enzymes, TNF-α and serum lipid profiles.

Background. There is an increasing interest in the role of adipocytokines in cardiovascular pathophysiology. Aim. The aim of the study was to compare visfatin levels, a novel adipokine, in patients with heart failure (HF) due to the left ventricular systolic dysfunction with those in age- and body mass index (BMI) - matched healthy controls in relation to the parameters of glucose metabolism and high sensitivity C-reactive protein (hsCRP) levels. Material/Subjects and Methods. The study population consisted of 28 males with systolic HF referred for cardiopulmonary exercise testing, divided into two subgroups based on their NYHA class (HF patients NYHAI+II, n=17, and HF patients NYHAIII+IV, n=11), and 23 controls. The following indices were measured in a serum samples: visfatin, hsCRP, glucose and lipid metabolism parameters, and the insulin resistance index HOMAIR (homeostasis model assessment insulin resistance) was calculated. Results. Concentrations of visfatin and high-density lipoprotein cholesterol (HDL-cholesterol) in the HF subjects were significantly lower (p≤0.01) than in controls. The Kruskal-Wallis test showed significant differences between three groups (controls and both subgroups of heart failure patients) in mean levels of visfatin, hsCRP, glucose, HOMAIR and HDL-cholesterol. Conclusion. Serum visfatin concentrations in patients with systolic HF, particularly with more advanced NYHA classes, are significantly lower in comparison to healthy controls and are independent of age or anthropometric and metabolic parameters.

The aim of this study was to analyze the effects of sports training on the physiological response to supra-maximal exercise during consecutive phases of the annual training cycle. The study was carried out in volleyball players at the onset of each training phase. VO2 max was determined by an indirect method using the Ästand-Rhyming nomogram and biochemical analyses were performed before and after the Wingate test. Concentrations of lactate in capillary blood were measured and levels of glucose, insulin, visfatin, resistin, thiobarbituric acid reactive substances (TBARS) of serum and the total antioxidative status of plasma were determined using venous blood.Most significant differences with respect to physiological and biochemical variables centered around the pre-competitive phase when compared to other phases of the annual training cycle. Blood visfatin concentration in highly trained volleyball players is reduced by supra-maximal exercise, whereas levels of resistin remain relatively constant at rest. With the exception of the competitive phase, values of the insulin resistance index fit within the reference range. Levels of lipid peroxidation products were inversely correlated with the insulin resistance index and resistin concentrations.The physical training during the annual cycle does not affect resistin levels, but influences insulin, glucose and visfatin concentrations, along with markers of pro-oxidant/antioxidant balance in beach volleyball players.
