Effects of gallic acid and physical exercise on passive avoidance memory in male rat

Learning and memory play main roles in daily life of human, and memory represents the basis of all trainings and learning. The aim of the current study is to investigate the effects of gallic acid and physical exercise on the levels of passive avoidance memory in rat. In this experimental study, 46 rats ...

Cardiovascular responses after isometric handgrip exercise at different intensities in healthy men

ABSTRACT The 30% maximal voluntary contraction protocol for isometric handgrip exercise is widely used to improve the cardiovascular system. However, it is unknown whether intensity modulation affects these responses. Objective: To analyze acute cardiovascular responses after isometric handgrip exercise ...

A detailed comparison of oxygen uptake kinetics at a range of exercise intensities

Motriz (Online); 25 (1), 2019
Aim: The aim of this study was to comprehensively examine oxygen uptake (V̇O2) kinetics during cycling through mathematical modeling of the breath-by-breath gas exchange responses across eight conditions of unloaded cycling to moderate to high-intensity exercise. Methods: Following determination of G...

Heart rate deflection point as an alternative to determining the anaerobic threshold in dyslipidaemic patients

Motriz (Online); 25 (1), 2019
Aim: The aim of the present study was to verify the agreement between the ventilatory method (VT) and the alternative method of heart rate deflection point (HRDP) in determining the anaerobic threshold (AT) during incremental treadmill test in dyslipidaemic patients. Methods: Twenty-seven dyslipidaemi...

Chronic noncommunicable diseases multimorbidity and its association with physical activity and television time in a representative Brazilian population

Abstract: Lifestyle behaviors need to be more explored within the context of chronic noncommunicable disease (NCD) multimorbidity. This study aimed to investigate the association of multimorbidity with physical activity and sedentary behavior in a representative Brazilian population (n = 52,929). A cross...

Twice-weekly exercise training reduces oxidative stress and proinflammatory cytokine levels in elder women

Motriz (Online); 25 (3), 2019
Aim: Reactive oxygen species and high concentrations of proinflammatory cytokines are related to diseases that are often triggered during the aging process. This study aimed to investigate the effect of moderate-intensity physical exercise, twice a week, on oxidative stress and inflammation biomarkers. ...

Anxiety increases the blood pressure response during exercise

Motriz (Online); 25 (3), 2019
Aim: The hypothesis that higher levels of anxiety promote greater blood pressure (BP) responses during physical exercise is tested. The hypothesis that metaborreflex response is increased in an anxious individual is tested as well. Methods: There were 43 volunteers divided by anxiety level: 12 volunte...
