Abstract
The main purpose of this study was to investigate the effects of 12 weeks of resistance training (RT) on phase angle (PhA), inflammatory and oxidative stress biomarkers, and to evaluate whether these RT-induced adaptations are related to PhA changes. Fifty-one older women (70.6 ± 5.1 years; 26.9 ± 4.2 kg/m2 ) were randomly allocated into a training group (TG) that performed 12-week RT or a nonexercising control group (CG). The PhA (Xitron), body composition (DXA), and blood sample measurements (after a 12 hours fast) were performed before and after the intervention. The TG showed a significant (P < .05) increase in PhA (TG: +7.4±5.9% vs CG: -3.6 ± 8.8%), and interleukin-10 (IL-10; TG: +51.8 ± 71.1% vs CG: -46.6 ± 38.0%), and a decrease in tumor necrosis factor alpha (TNF-α; TG: -15.2 ± 11.1% vs CG: +6.9±17.7%), interleukin-6 (IL-6; TG: -17.9 ± 17.8% vs CG: +6.1 ± 24.8%), and C-reactive protein (CRP; TG: -24.1 ± 19.9% vs CG: +43.8 ± 31.1%). Moreover, TG upregulated catalase (TG: +11.4 ± 15.0% vs CG: -6.7 ± 10.2%). Changes in TNF-α (r = -.71), CRP (r = -.65), lower advanced oxidation protein products (r = -.55), and catalase (r = +.73) after RT were correlated with changes in PhA (P < .05). These results suggest that RT improves PhA, inflammatory and oxidative stress biomarkers, and the changes in inflammatory and oxidative damage markers are correlated with changes in PhA.

Abstract
This study aimed to evaluate changes in total body water (TBW) in soccer athletes using a deuterium oxide dilution method and bioelectrical impedance (BIA) formulas after 7 days of creatine supplementation. In a double-blind controlled manner, 13 healthy (under-20) soccer players were divided randomly in 2 supplementation groups: Placebo (Pla, n=6) and creatine supplementation (CR, n=7). Before and after the supplementation period (0.3 g/kg/d during 7 days), TBW was determined by deuterium oxide dilution and BIA methods. 7 days of creatine supplementation lead to a large increase in TBW (2.3±1.0 L) determined by deuterium oxide dilution, and a small but significant increase in total body weight (1.0±0.4 kg) in Cr group compared to Pla. The Pla group did not experience any significant changes in TBW or body weight. Although 5 of 6 BIA equations were sensitive to determine TBW changes induced by creatine supplementation, the Kushner et al. 16 method presented the best concordance levels when compared to deuterium dilution method. In conclusion, 7-days of creatine supplementation increased TBW determined by deuterium oxide dilution or BIA formulas. BIA can be useful to determine TBW changes promoted by creatine supplementation in soccer athletes, with special concern for formula choice.

Abstract
The marker most frequently used to indicate the level of lipid peroxidation in the field of exercise and sports is malondialdehyde (MDA), which can be determined by many different techniques. However, there are few studies discussing differences and advantages of the methods for MDA assay in sports science field. The aim of the present study was to compare three techniques for quantification of MDA in plasma of humans subjected to acute exercise. MDA was determined by high performance liquid chromatography (MDA-HPLC), thiobarbituric acid reactive species (MDA-TBARS) and 1-methyl-2-phenylindole (MDA-MP) techniques in the plasma of 8 healthy male soccer athletes before and after acute exercise. Acute exercise significantly increased (P<0.05) plasma MDA concentration determined by MDA-HPLC (18%) and MDA-TBARS (56%) techniques. MDA-MP technique did not reveal significant differences, although it increased 25% after exercise. When correlated to the gold standard (MDA-HPLC), MDA-TBARS and MDA-MP techniques showed weak Lin concordance coefficients and non-significant correlation. Also, MDA-TBARS and MDA-MP techniques overestimated the MDA-HPLC technique by 100 and 122%, respectively. In conclusion, MDA-HPLC and MDA-TBARS are sensitive to detect change in MDA induced by acute exercise. MDA-HPLC is the most suitable technique for accurate detection of MDA in sports and exercise area due to its sensitivity and accuracy.

Abstract
AIM Aim of the study is to investigate the modulations of oxidative stress biomarkers and some antioxidants induced by high intensity interval training bout and its relation to swimming performance. METHODS Ten swimmers performed a set of 8 maximal swims along 100 m by style of their specialty, with 10 minute for a rest. The concentration of blood lactate ([Lac]) was determined after each swim. The lactate tolerance index (LTI) was determined by the ratio between [Lac] and the respective times of execution of the 8 swims. The time to complete first 100 m swim at maximum effort (P100) and the international point score (IPS) reached in a specific competition were considered performance parameters. Venous blood was collected before and after the anaerobic training effort. RESULTS Mean blood lactate concentration in the eight swims was 10.9 ± 1.2 mM. Significant increases were observed for TBARS (pre: 4.1±0.7 ?mol/L; post: 4.9±1.1. ?mol/L), CK (pre: 206.4±170.7 U/L; post: 244.4±176.9. U/L), GSH (pre: 0.52±0.06; post: 0.62±0.05. mM), and ascorbic acid (pre: 0.06±0.02; post: 0.11±0.03. mg/dL) after the anaerobic training bout compared to the values obtained before it. In addition, significant correlations (P < 0.05) were detected between LTI and P100 (r = -0.87) and IPS (r = 0.64) and between variation of ascorbic acid and P100 (r = -0.60). CONCLUSION Anaerobic training bout proposed induces oxidative stress and cell muscle damage markers as well as modulates some antioxidants of competitive swimmers. The modulation of ascorbic acid seems to play an important role in the performance of these athletes.
