AB  - A randomized, double-blind, placebo-controlled study was conducted to investigate the influence of supplementation with a superoxide dismutase (SOD)-rich plant extract on markers of oxidative stress, zonulin levels and the performance of elite athletes. Participants were 30 international-level rowers, divided into an experimental group (n = 15) and a control group (n = 15). The rowers performed a maximal effort incremental test on a rowing ergometer at the beginning and at the end of the study. Markers of oxidative stress (total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), superoxide dismutase (SOD), glutathione peroxidase (GPx), advanced oxidation protein products (AOPPs), malondialdehyde (MDA), sulfhydryl (SH) groups, bilirubin, uric acid, albumin and zonulin) were determined in serum. A lower TOS (p = 0.010) and OSI (p = 0.004), a lower MDA (p = 0.001) and a higher level of SH groups (p = 0.031) were observed in the experimental group after supplementation. Physical performance was evaluated through metabolic efficiency, taking lactate levels and power output on the ergometer into account. After 6 weeks of supplementation, the relative increase in metabolic efficiency at a 4 mmol/L lactate concentration and maximal effort was significantly higher in the experimental group (p = 0.004 and p = 0.015, respectively). These results suggest that supplementation with a SOD-rich extract promotes lower oxidative stress, better antioxidant protection and, consequently, the better work performance of athletes.

AB  - This study aimed to investigate the effect of supplementation with plant origin superoxide dismutase (SOD), GliSODin, on parameters of muscle damage, metabolic, and work performance at international level rowers. Twenty-eight rowers were included in a randomized, double-blind study. The study was conducted during a 6-week preparation period. At the beginning of the study and after 6 weeks of the supplementation period, all rowers were tested on a rowing ergometer. Blood samples were taken from the antecubital vein before and after every ergometer testing. Muscle damage markers creatine kinase (CK) and lactate dehydrogenase (LDH), total antioxidant capacity (TAC), inflammation parameters interleukin-6 (IL-6), and C-reactive protein (CRP) were measured. Rowing performance was assessed by lactate level in capillary blood and power output on the rowing ergometer. After supplementation, experimental group had significantly lower CK (p = 0.049) and IL-6 (p = 0.035) before and IL-6 (p = 0.050) after exhausting exercise on ergometer. Relative change of power output at 4 mmol/L concentration of lactate in blood, considering the initial and final test, was significantly higher (p = 0.020) in the supplemented group. It was concluded that GliSODin could be considered a good supplement in preventing some deleterious effects of intensive physical activity, including inflammation and muscle damage, and consequently, to enable a better rowing performance of elite rowers.

AB  - This study aimed to explore the set of variables related to skeletal muscle mass (SMM) inboth sexes, and to create age- and sex-related models of changes in SMM, using the most representativeindicator of muscular status. Body composition was assessed in 8733 subjects (♀=3370 and♂=5363),allocated into subsamples according to age: 18–29.9, 30–39.9, 40–49.9, 50–59.9, 60–69.9, and 70.0–79.9years. Nine variables were used: protein mass, protein percent, protein mass index, SMM, percentof SMM, SMM index,  fat-free mass,  fat-free mass index,  and protein/fat index.   Univariate andmultivariate analysis of variance (ANOVA and MANOVA) were used to determine between- andwithin-sex difference in all variables by age. Correlation analysis established the relationship betweenage and muscularity variables. Principal Component Analysis extracted the variables that loadedhighest in explaining muscularity, while regression analysis determined the linearity of associationbetween the age and indicators of muscular status. Variables SMMI and PSMM were extracted asthe most sensitive to age, with SMMI being gender-independent while showing the parabolic andsinusoidal form of change as function of ageing in males and females, respectively; and PSMM beingsex-dependent while showing a linear trend of decrease in both sexes.

AB  - The Aim. The aim of this paper is to define the contractile characteristics of maximal isometric handgrip force and to establish possible differences between the students of the Universities of Chelyabinsk and Belgrade. The secondary aim is to create a practically applicable initial model in order to explore the mentioned characteristics in the future. Material and methods. For the purposes of this research, the overall sample of 225 subjects was tested. 91 subjects were from Russia and 134 were from Serbia. The results were gathered using a strain gage and a standardized isometric handgrip test protocol. The contractile properties of HG muscle force were measured in relation to three different contractile dimensions: the maximal muscle force (Fmax), the maximal explosive muscle force (RFDmax), the time need for achieving maximal (tFmax) and maximal explosive (tRFDmax) muscle force. Results. This study has shown that there are no generally statistically significant differences for all observed variables of HG contractile characteristics between tested Russian and Serbian students. Based on the results of the present study, six different models of the equation for evaluation of HG contractile characteristics of female and male students, i.e. young adults, were made. All defined models are highly statistically significant, accurate and sensitive in the prediction of the general distributive position of an individual or particular group of subjects in relation to the measured contractile characteristics. Conclusions. The obtained results can generally indicate the stability of potential to exert the given contractile characteristic in relation to the population of similar evolutionary (Slavs) at different geographical background.

AB  - Introduction: The aim of this study was to establish the sensitivity and specificity of the microcytic anemia factor (Maf((R))), which is generated by the Coulter LH 750 analyzer in the evaluation of iron depletion and iron-deficient erythropoiesis in athletes. Methods: A total of 142 athletes were divided into three groups: with iron depletion, with iron-deficient erythropoiesis, and controls. The following parameters were measured: RBCs (red blood cells), Hb (hemoglobin), Hct (hematocrit), MCV (mean cellular volume), MCH (mean cell hemoglobin), MCHC (mean cell hemoglobin corpuscular), RDW (red cell distribution width), Maf((R)), Reticulocytes, Ferritin, sTfR (soluble transferrin receptor), Transferrin, Haptoglobin, IL- 6 (Interleukin-6), hs-CRP (high-sensitivity C-reactive protein). Results: The best Maf((R)) value to exclude iron depletion in athletes was 130.3, showing a sensitivity of 72.6% and a specificity of 57.3%. The AUC was 0.690 (CI 95% 0.607-0.765, P lt 0.001). ROC curve analysis for Maf((R)) in the diagnosis of iron-deficient erythropoiesis indicates sensitivity of 61.5%, and specificity of 93.0%, with AUC=0.826 (CI 95% 0.754-0.885, P lt 0.001) and on cutoff value 114. Conclusions: This study shows that Maf((R)), generated by the Coulter LH 700 Series hematology analyzers, performs very well in discriminating healthy athletes and those with different stages of iron deficiency. Also, in cost/benefit terms, monitoring of Maf((R)) is justified as a low cost, effective screening parameter for determining iron status in athletes.

The following parameters were measured: RBCs (red blood cells), Hb (hemoglobin), Hct (hematocrit), MCV (mean cellular volume), MCH (mean cell hemoglobin), MCHC (mean cell hemoglobin corpuscular), RDW (red cell distribution width), Maf((R)), Reticulocytes, Ferritin, sTfR (soluble transferrin receptor), Transferrin, Haptoglobin, IL- 6 (Interleukin-6), hs-CRP (high-sensitivity C-reactive protein). Results: The best Maf((R)) value to exclude iron depletion in athletes was 130.3, showing a sensitivity of 72.6% and a specificity of 57.3%. The AUC was 0.690 (CI 95% 0.607-0.765, P lt 0.001). ROC curve analysis for Maf((R)) in the diagnosis of iron-deficient erythropoiesis indicates sensitivity of 61.5%, and specificity of 93.0%, with AUC=0.826 (CI 95% 0.754-0.885, P lt 0.001) and on cutoff value 114. Conclusions: This study shows that Maf((R)), generated by the Coulter LH 700 Series hematology analyzers, performs very well in discriminating healthy athletes and those with different stages of iron deficiency. Also, in cost/benefit terms, monitoring of Maf((R)) is justified as a low cost, effective screening parameter for determining iron status in athletes.",

AB  - The aim of this study was to profile hematological, oxidative stress, and immunological parameters in male athletes who practiced combat sports and to determine whether the type of combat sport influenced the measured parameters. Eighteen karate professionals, 15 wrestlers, and 14 kickboxers participated in the study. Hematological, iron-related, oxidative stress, and immunological parameters were measured at the beginning of a precompetitive period. The general linear model showed significant differences between the karate professionals, wrestlers, and kickboxers with respect to their hematological and iron status parameters (Wilks' Lambda = 0.270, F = 2.186, p  lt  0.05) and oxidative stress status (Wilks' Lambda = 0.529, F = 1.940, p  lt  0.05). The immature reticulocyte fraction was significantly higher in wrestlers (0.30 +/- 0.03) compared with kickboxers (0.24 +/- 0.04; p  lt  0.05) and karate professionals (0.26 +/- 0.04; p  lt  0.05). Low hemoglobin density was significantly lower in wrestlers and kickboxers (p  lt  0.05) compared with karate professionals (karate: 3.51 +/- 1.19, wrestlers: 1.95 +/- 1.10, and kickboxers: 1.77 +/- 0.76). Significant differences were observed between the karate professionals and wrestlers with respect to their pro-oxidant-antioxidant balance (437 +/- 103 vs. 323 +/- 148, p  lt  0.05) and superoxide-dismutase activity (SOD) (73 +/- 37 vs. 103 +/- 30, p  lt  0.05). All the measured parameters (with the exception of SOD activity) fell within their physiological ranges, indicating that the study participants represented a young and healthy male population. Hematological parameters differed between kickboxers and karate professionals. The low pro-oxidant-antioxidant balance and high SOD activity in wrestlers could be associated with the long-term impact of wrestling as a type of strenuous exercise.

AB  - Physical activity has been shown to increase the production of free radicals to a point that can exceed internal protective antioxidant system. The harmful effects of free radicals are neutralized by activity of antioxidant enzymes and numerous non-enzymatic antioxidants, including vitamins, glutathione, ubiquinone and flavonoids. Defence mechanisms against free radical-mediated oxidative damage also include the iron binding proteins such as transferrin and ferritin. Ferritin and trensferrin are able to restrict the availability of iron to participate in conversion of hydrogen peroxide to toxic hydroxyl radicals by Fenton reaction. Because the endogenous antioxidant system may not be sufficient to prevent exercise-induced free radical generation and consequent oxidative damage, supplementation of antioxidants may have important effect antioxidant status in athletes. The aim of the present work was to examine the association of physiological iron carriers with oxidative stress in elite athletes. One hundred and five elite athletes were divided into two groups: supplemented group which consisted of sixty-five athletes who regularly use antioxidant supplements and control group which consisted of forty athletes that were without antioxidants intake. Following parameters were measured: albumin, ferritin, transferrin, advanced oxidation protein products (AOPP), lipid hydroperoxides (LOOH), biological antioxidative potential (BAP), superoxide dismutase (SOD) and total sulphydryl group concentration (SH groups). Multivariate analysis of covariance (MANCOVA, Wilks' lambda) was performed to test the hypotheses that supplementation (fixed factor) and antioxidative proteins (indicated via albumin, ferritin and transferrin) (covariates) have a significant effect on the oxidative stress parameters (dependent variables). The SOD activity (P=0.024) and sulphydryl group concentration (P=0.042) were significantly higher in supplemented athletes. Multivariate analysis of covariance indicated ferritin (P<0.001) and transferrin (P=0.001) as significant covariates, which have contributed 37.1 % and 22.8% to variability of oxidative stres parameters, respectively. The transferrin exhibited linear relationships with LOOH (R2 = 0.127; P < 0.001) and AOPP (R2 = 0.113; P < 0.001) while ferritin exhibited non-linear (logarithmic) relationships with this parameters (AOPP: R2 = 0.201, y = 82.3 -15.9log(x), P<0.001; LOOH: R2 = 0.256, y = 193 -33.3log(x), P<0.001). In conclusion, proteins that regulate iron transport and storage, transferrin and ferritin, were negatively related with oxidative damage in professional athletes regardless of antioxidant supplementation.

AB  - We investigated the iron-related haematological parameters in both male and female athletes participating in different sporting disciplines necessitating different metabolic energy demands. A total of 873 athletes (514 males, mean age: 22.08 +/- A 4.95 years and 359 females, mean age: 21.38 +/- A 3.88 years) were divided according to gender and to the predominant energy system required for participation in sport (aerobic, anaerobic or mixed) and haematological and iron-related parameters were measured. For both male and female athletes, significant differences related to the predominant energy system were found at a general level: male (Wilks' lambda = 0.798, F = 3.047, p  lt  0.001) and female (Wilks' lambda = 0.762, F = 2.591, p  lt  0.001). According to the ferritin cutoff value of 35 mu g/L, whole body iron and sTfR significantly differed in all three groups of male and female athletes (p  lt  0.001). The percentage of hypochromic erythrocytes in male athletes was significantly higher only in those who required an anaerobic energy source (p  lt  0.001), whilst in the females hypochromic erythrocytes (p  lt  0.001) and haemoglobin (anaerobic, p = 0.042; mixed, p = 0.006) were significantly different only in anaerobic and mixed energy source athletes. According to the ferritin cutoff value of 22 mu g/L, in females, whole body iron, sTfR and hypochromic erythrocytes were significantly higher in all three groups of athletes than those below the aforementioned cutoff value (p  lt  0.001). We conclude that the predominant energy system required for participation in sport affects haematological parameters. sTfR and body iron proved to be reliable parameters for monitoring the dynamics of iron metabolism and could contribute to successful iron-deficiency prevention.

AB  - The aim of the present study was to examine the association of proteins that regulate iron transport/storage content and acute phase response with oxidative stress in male and female athletes. Serum ferritin, transferrin, soluble transferrin receptor, C-reactive protein, interleukin-6 and oxidative stress parameters (reactive oxygen metabolites, superoxide anion, advanced oxidation protein products, lipid hydroperoxides, superoxide-dismutase and pro-oxidant-antioxidant balance) were determined in 138 athletes (73 females and 65 males). A general linear model indicated significant gender differences between athletes in terms of reactive oxygen metabolites (307.48 +/- 61.02 vs. 276.98 +/- 50.08; P = 0.030), superoxide-dismutase (114.60 +/- 41.64 vs. 101.42 +/- 38.76; P = 0.001), lipid hydroperoxides (149.84 +/- 38.95 vs. 101.43 +/- 39.26; P  lt  0.001), pro-oxidant-antioxidant balance (512.40 +/- 148.67 vs. 413.09 +/- 120.30; P = 0.002), advanced oxidation protein products (1.49 +/- 0.30 vs. 0.91 +/- 0.25; P  lt  0.001) and superoxide (2.61 +/- 0.36 vs. 2.22 +/- 0.35; P = 0.001), which were all significantly higher in females. Multivariate analysis of covariance indicated gender (P  lt  0.001), training experience (P = 0.004), Creactive protein (P = 0.002), soluble transferrin receptor (P = 0.004) and transferrin (P  lt  0.001) as significant covariates. Gender accounted for the largest proportion of variability for all oxidative stress parameters (46.3%) and female athletes were more susceptible to oxidative stress. Iron transport and storage proteins (transferrin and ferritin), but also acute phase reactants, were negatively related factors for oxidative stress. In conclusion, variation in the ferritin level may contribute to the different oxidative stress level between the sexes.

AB  - Aim. The objectives of this study were: 1) to evaluate pro-oxidant-antioxidant balance (PAB) associations with the commonly measured parameters of oxidative stress and antioxidative defence in elite female volleyball athletes; 2) to investigate changes in the parameters of oxidative stress during a period of intense training and dietary antioxidant supplementation. Methods. Twenty-seven female volleyball players participated in this study. Blood samples were collected the day before the pre-competitive mesocycle training period began. After the first blood sample donation and during the next six weeks fourteen players (supplemented group) received a cocktail of antioxidants while thirteen of them (control group) received no dietary supplementation. The following parameters were measured: reactive oxygen metabolites (ROMs), superoxide anion (O(2)(-)), malondialdehyde (AIDA), advanced oxidation protein products (AOPP), lipid hydroperoxides (LOOH), biological antioxidative potential (BAP), paraoxonase activity toward paraoxon (POase) and diazoxon (DZOase), superoxide dismutase (SOD), total sulphydryl group concentration (SH groups) and pro-oxidant-antioxidant balance. Results. Significant associations were observed between biomarkers of oxidative damage with PAB in multiple linear regression model in the supplemented and the control groups (82.3% vs. 83.1%) before training and in the control group (82.1%) after training. Significant associations between anti-oxidative defence parameters and PAB values were found in the supplemented group after six-weeks of training (57%). Conclusion. In the absence of antioxidant supplementation, PAB values were dependent on the association with biomarkers of oxidative damage before and after training. After a six-week training period and the applied antioxidant supplementation, PAB values were under the influence of nonenzymatic anti-oxidative defence.

AB  - The main purpose of this study was to demonstrate the impact of different training regimes and the type of metabolism that predominates as the source of energy on the oxidative stress / anti-oxidative defense status in elite-level trained athletes. One hundred twenty-four athletes were divided into three groups: 'aerobic' (karate, rowing, triathlon), 'anaerobic' (wrestling and swimming) and 'mixed' (volleyball, water polo, kick boxing). The following parameters were measured: oxidative stress status parameters: [(reactive oxygen metabolites (ROMs), superoxide anion (O2 -), malondialdehyde (MDA), advanced oxidation protein products (AOPP) and lipid hydroperoxides (LOOH)] and anti-oxidative defense parameters [biological anti-oxidative potential (BAP), superoxide-dismutase (SOD), sulphydryl groups (-SH) and pro-oxidant-antioxidant balance (PAB)]. In general, significant differences were found in oxidative stress parameters between three experimental groups (Wilks' Lambda = 0.366, F value = 8.185, p  lt  0.001). Comparing the athletes from the anaerobic and mixed groups, we found that the anaerobic group had significantly lower ROMs (p = 0.019), AOPP (p  lt  0.001), O2 - (p = 0.003) and LOOH (p  lt  0.001). The aerobic group of athletes differed from the group with mixed training regime by lower AOPP, MDA, O2 - and LOOH values (p  lt  0.001). Discriminant analysis of the three experimental groups indicated protein oxidation marker (AOPP) and pro-oxidant-antioxidant balance as the most important discriminant variables. Oxidative stress status parameters adequately discriminated 74.2 % of the athletes with different energy expenditure during their training programs. The results obtained provide evidence that there are differences in the oxidative stress / anti-oxidant defense status between athletes that have different energy expenditure during exercise and identify athletes who participate in team sports as most susceptible to oxidative stress. .

AB  - Objective: The aim of this study was to evaluate how conditions that precede anaemia (iron store depletion and iron-deficient erythropoiesis) affect human serum paraoxonase PON1 activity. Design and methods: Based on haemoglobin, transferrin saturation and serum ferritin values 119 athletes were divided into three groups: with iron depletion, with deficient erythropoiesis and controls. The following parameters were measured: paraoxonase activity towards paraoxon (POase) and diazoxon (DZOase), lipid hydroperoxides (LOOH), the pro-oxidant-antioxidant balance (PAB), red blood cells (RBC) and lipid status. Results: Significant differences were found between athletes with different stages of iron deficiency and controls with respect to PON 1 activity and oxidative stress status parameters (Wilks' Lambda = 0.712, F = 5.241, p lt 0.001, eta(2) = 0.156). There was no significant difference between the PON1 192 Q and R polymorphism distribution in the two groups of athletes with different stages of iron deficiency and controls (chi(2) = 1.086; p = 0.896). PON1 activity was positively correlated with RBCs, haemoglobin, transferrin saturation (p lt 0.001) and ferritin (p = 0.037) and negatively correlated with LOOH (p = 0.044) in all three study groups. Conclusions: Deficient erythropoiesis in athletes contributes to impaired PON1 activity. In contrast, iron depletion, regardless of increased oxidative stress, does not affect PON1 activity.

AB  - The aim of this study was to determine the impact of long-term training on elite female volleyball players and to determine parameters that could discriminate them according to the level of oxidative stress-associated adaptation. Fifty-four elite female volleyball players were divided into 3 groups (1: below-average training experience  lt 8.0 years, 2: average training experience between 8.0 and 10.5 years and 3: above-average training experience > 10.5 years). The measured parameters were reactive oxygen metabolites, biological anti-oxidative potential, superoxide anion, malondialdehyde, advanced oxidation protein products, lipid hydroperoxides, paraoxonase activity, superoxide-dismutase activity and sulphydryl groups. Multiple discriminant analysis of the oxidative stress status parameters between the three groups of athletes indicated a statistically significant difference (Wilks' lambda=0.458, X-2=35.898, p=0.031). The most important discriminant variables, superoxide-dismutase and superoxide anion, were the best indicators of differences between groups with different training experience. The significantly higher values were found in Group 3 compared with Group 1 in superoxide-dismutase activity (141 +/- 32 vs. 86 +/- 46; p=0.002), sulphydryl groups (p=0.031), and reactive oxygen metabolites (p = 0.042). The significantly lower superoxide anion was found between Group 3 and Group 1 (377 +/- 187 vs. 1183 +/- 905; p=0.001). Oxidative stress status parameters adequately discriminated 68.5% of athletes with different training experience.
