Eccentric, but not concentric muscle contraction induce inflammation and impairs fibrinolysis in healthy young men.

Different types of muscle contraction can cause different damage to the musculature and differences in inflammatory responses. Acute increases in circulatory inflammation markers can influence the crosstalk between coagulation and fibrinolysis processes, increasing the risk of thrombus formation and detrimental cardiovascular events. The aim of this study was to analyze the effects of concentric and eccentric exercise on hemostasis markers, C-reactive protein (CRP), and the relationship between these variables.

Effects of exercise modalities on decreased blood pressure in patients with hypertension.

This study aimed to evaluate the acute effects of aerobic and resistance exercises on blood pressure and endothelial blood markers. We also correlated post-exercise blood pressure response with baseline cardiovascular parameters in middle-aged patients with hypertension. This cross-sectional study randomized 54 volunteers into the aerobic exercise group (AG, = 27; 45.

Effects of grape juice consumption on oxidative stress and inflammation in male volleyball players: A randomized, double-blind, placebo-controlled clinical trial.

Introduction: Some foods are also demonstrated benefits, such as anti-inflammatory, antioxidant, and ergogenic activity, similar to that of sports supplements. Grape juice has been considered an important source of polyphenols and these compounds could promote positive effects to the sports players. In this sense, the objective was to evaluate the effects of purple grape juice consumption on indicators of oxidative stress, inflammation, muscle damage, global histone H4 acetylation levels, and muscle strength and muscle power in volleyball athletes.

Effect of aerobic and resistance exercise training on inflammation, endothelial function and ambulatory blood pressure in middle-aged hypertensive patients.

Objective: The current randomized controlled trial tested the hypothesis that both aerobic training and dynamic resistance training will improve inflammation, endothelial function and 24-h ambulatory blood pressure (ABP) in middle-aged adults with hypertension, but aerobic training would be more effective.

Methods: Forty-two hypertensive patients on at least one antihypertensive medication (19 men/23 women; 30-59 years of age) were randomly assigned to 12 weeks of supervised aerobic training (n = 15), resistance training (n = 15) or a nonexercise control (n = 12) group. Inflammation, endothelial function, 24-h ABP and related measures were evaluated at pre and postintervention.

Acute effects of strength exercise with blood flow restriction on vascular function of young healthy males.

Background: Strength training with blood flow restriction (STBFR) provokes similar neuromuscular adaptations to traditional strength training using low training loads. However, there is a need for better understanding of the repercussions for antioxidant parameters and vascular function.

Objectives: The objective of the present study was to investigate the effects of a session of low intensity strength training with blood flow restriction, compared with high intensity and low intensity strength training without blood flow restriction, on the levels of nitric oxide products and antioxidant enzyme activity in healthy young men.

Endothelial function and lipid profile of individuals with schizophrenia participating in a supported employment program.

Background: The social function of individuals with schizophrenia is usually poor and this population exhibits a sedentary lifestyle. Social participation, inclusion in the world of work in particular, might favorably interfere with the lives of these individuals by reducing sedentarism and improving their state of health.

Objective: To analyze the lipid profile and endothelial function markers among individuals with schizophrenia enrolled in a supported employment program.

Acute response of peripheral CCr5 chemoreceptor and NK cells in individuals submitted to a single session of low-intensity strength exercise with blood flow restriction.

The purpose of this study was to compare the peripheral expression of natural killers and CCR5 in a session of low-intensity strength training with vascular occlusion and in high-intensity training. Young males were randomized into session groups of a high-intensity strength training (HI) and a session group of low-intensity strength training with vascular occlusion (LI-BFR). The exercise session consisted in knee extension and bicep curl in 80% 1RM (HI) and 30% 1RM (LI-BFR) with equalized volumes.

The effects of diet- and diet plus exercise-induced weight loss on basal metabolic rate and acylated ghrelin in grade 1 obese subjects.

Background: Diet and exercise are often prescribed as primary intervention regarding obesity-related disorders. Additionally, recent studies have shown beneficial effects of weight loss through diet and exercise in ghrelin concentrations in obese subjects. The aim of this study was to evaluate the effects of a 5% weight loss on lipid profile, resting metabolic rate (RMR), and acylated ghrelin (AG) using two different methods of intervention (diet or diet plus exercise).

Effects of L-arginine supplementation on blood flow, oxidative stress status and exercise responses in young adults with uncomplicated type I diabetes.

Background And Aims: Vascular disease is the principal cause of death and disability in patients with diabetes, and endothelial dysfunction seems to be the major cause in its pathogenesis. Since L-arginine levels are diminished in conditions such as type 1 and type 2 diabetes, in this work we aimed to verify the effects of L-arginine supplementation (7 g/day) over the endothelial function and oxidative stress markers in young male adults with uncomplicated type 1 diabetes. We also investigated the influences of L-arginine administration on vascular/oxidative stress responses to an acute bout of exercise.

[Levels of beta-endorphin in response to exercise and overtraining].

Overtraining (OT) is a complex and multifactorial sport phenomenon, and there is no independent marker that can diagnose OT. Interestingly, some symptoms of OT are related to beta-endorphin (beta-end(1-31)) effects. Some of its effects, such as analgesia, increasing lactate tolerance, and exercise-induced euphoria, are important for training.

The effect of ABO blood group on von Willebrand response to exercise.

Individuals of O blood group have significantly lower plasma levels of either Factor VIII (FVIII) or the von Willebrand factor (vWF). Conversely, there is accumulating evidence that elevated FVIII-vWF levels may represent an important risk factor for ischemic heart and venous thromboembolic disease. In this study, individuals exercised for 20 minutes at 10% below the first ventilatory threshold (aerobic threshold), which corresponds to 48% of maximum oxygen uptake.

Effective force and economy of triathletes and cyclists.

The effective force applied on the crank, the index of pedalling effectiveness, and the economy of movement at 60, 75, 90, and 105 rev/min cadences were examined in nine cyclists and eight triathletes. Tests were performed on two days. Maximal oxygen uptake was measured and the second ventilatory threshold was estimated on day 1 using a stationary bicycle.

Oxidative stress after three different intensities of running.

In 8 trained subjects (T) and 9 untrained subjects (UT), lipid peroxidation (LPO), total antioxidant capacity (TRAP), superoxide dismutase, catalase, and glutathione peroxidase (GPx) activities were measured in the blood before and after three different intensities of exercise on the treadmill, determined from ventilatory threshold and maximal oxygen uptake data, obtained from a maximal aerobic power test. In plasma, LPO decreased from 3589 +/- 193 to 3274 +/- 223 cps x mg Hb(-1) (p < 0.05), and TRAP increased from 304 +/- 45 to 384 +/- 57 micromol x L(-1) trolox (p < 0.
