Efeito da suplementação de erva mate (Ilex paraguariensis) sobre a capacidade antioxidante total em atletas futebolistas em teste exaustivo em esteira

Introduction: Physical exercise are related to high oxygen consumption, leading to increase on reactive oxygen species (ROS) generation and subsequent oxidative stress. Concomitantly, physical training can improve the antioxidant defense systems, reducing the deleterious activity of ROS. The yerba mate (Ilex paraguariensis) has several bioactive compounds in its composition, providing important antioxidant activity in improving defense systems and reducing the damage caused by ROS. Few studies related to yerba mate with antioxidant effects during exercise. Objective: Evaluate whether the consumption-based drink yerba mate (Ilex paraguariensis) is able to increase the total antioxidant performance (TAP) after an exhaustive test on a treadmill. Methods: The sample counted with 15 female soccers players from Botucatu-SP female soccer team with a mean age of 22.1 ± 4.2 years. For laboratory tests , it was evaluated: triglycerides (TG), total cholesterol (TC) and fractions, glucose and gamma-GT were dosed by dry chemistry (Vitros® System, Johnson & Johnson). LDL-cholesterol was obtained by Friedwald formula. Total antioxidant performance (TAP) was obtained by the method of fluorescence assay for the measurement of plasma. Weight, height and body mass index (IMC) were measured, percentage of body fat was obtained by bioeletrical impedance analysis (Biodinâmics, modelo 450, USA). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Ramp Protocol). Maltodextrin was supplemented (30 g in 400 ml) 30 minutes after M0 with placebo (400 ml) or mate (5 g in 400 ml of water). Statistical analysis: ANOVA for repeated measures followed by Tukey's test set, p<0.05. Results: There was a decrease in the pH after exhaustive testing for water and tea (p<0.0001), the same was observed for bicarbonate (p<0.0001). In both groups pO₂ increased for ...

Reliability of peak O-2 uptake and O-2 uptake kinetics in step exercise tests in healthy subjects

To date little is known about the reliability of peak oxygen consumption (VO2pEAK) in incremental metronome paced step tests (1ST) and the reliability of on-kinetics VO2 has never been studied. We aimed to study the reliability of both tests. Eleven healthy subjects performed two ISTs until exhaustion. On two different days two duplicate 4 min constant metronome paced step tests (CST) were performed. VO2PEAK, mean response time (MRT) and phase II time constant (tau) were tested for reproducibility using the paired t-tests, in addition to the limits of agreement (LOA) and within subject coefficient of variation (COV). With a 95% LOA of 0.38 to 0.26 L min(-1), -8.7 to 9.1 s and -9.9 to 10.5 s they exhibit a COV of 3%, 4.5% and 6.9% for VO2PEAK, MRT and tau respectively. ST are sufficiently reliable for maximal and submaximal aerobic power assessments in healthy subjects and new studies of oxygen uptake kinetics in selected patient groups are warranted.

Development of the color scale of perceived exertion: preliminary validation

This study developed a Color Scale of Perceived Exertion (RPE-color scale) and assessed its concurrent and construct validity in adult women. One hundred participants (18-77 years), who were habitual exercisers, associated colors with verbal anchors of the Borg RPE scale (RPE-Borg scale) for RPE-color scale development. For RPE-color scale validation, 12 Young (M = 21.7 yr., SD = 1.5) and 10 Older (M = 60.3 yr., SD = 3.5) adult women performed a maximal graded exercise test on a treadmill and reported perceived exertion in both RPE-color and RPE-Borg scales. In the Young group, the RPE-color scale was significantly associated with heart rate and oxygen consumption, having strong correlations with the RPE-Borg scale. In the Older group, the RPE-color scale was significantly associated with heart rate, having moderate to high correlations with the RPE-Borg scale. The RPE-color scale demonstrated concurrent and construct validity in the Young women, as well as construct validity in Older adults.

The respiratory metabolism of the castes of two leaf cutting ants, Atta laevigata (F. Smith, 1858) and Atta sexdens rubropilosa forel, 1908

1. 1. The respiration of the different castes of two species of leaf-cutting ants, Atta laevigata and Atta sexdens rubropilosa was measured in both workers and sexed forms. 2. 2. The respiratory rates (μl O2/mg(live)/hr) were, in A. laevigata, 0.644 (gardeners), 0.594 (cutters), 0.354 (soldiers), 0.233 (males) and 0.085 (females); in A. s. rubropilosa, 0.803 (gardeners), 0.748 (cutters), 0.510 (soldiers), 0.375 (males) and 0.274 (females), significantly higher than A. laevigata. 3. 3. All castes considered, the b-values of the equation relating oxygen consumption and weight in A. laevigata (0.53) were significantly different from that in A. s. rubropilosa (0.73). © 1981.

Metabolic activity of the sticker's lymphosarcoma

1. 1. Some parameters (glycolysis, respiration, levels of glycolytic enzymes) of the lymphoid cells from the Sticker's lymphosarcoma were established in order to better define the biochemical behavior of the venereal tumor of the dog. 2. 2. For comparative purposes lymphocytes from peripheral blood of normal tumor-bearing dogs were also studied. 3. 3. Lactic acid produced by the tumor cells during aerobic glycolysis is liberated in the reaction medium. 4. 4. Oxygen uptake is enhanced in the presence of succinate, but not with pyruvate, α-ketoglutarate, or malate as substrates. 5. 5. Higher levels of some of the enzymes from the glycolytic pathways as well as differences on the physicochemical and kinetic properties of the glycolytic regulatory enzymes are found in Sticker's tumor cells, when compared with the lymphocytes from peripheral blood of normal and tumor-bearing dogs. 6. 6. A fructose-bisphosphate positively modulated pyruvatekinase is found in the tumor cells. © 1987.
