Cardiac autonomic responses to high-intensity kettlebell training in untrained young women: A pilot study.

Background: and purpose: The autonomic recovery after exercise provides information about the cardiovascular overload employed during the training session. The autonomic response over a training course is unclear in exercises performed at high intensities, such as kettlebell training. The study aimed to characterize the cardiac autonomic modulation after exercise in three distinct phases of a high-intensity kettlebell training program in young women.

A Cardiopulmonary Exercise Testing for Prescribing High-Intensity Interval Training Sessions with Elastic Resistance.

Unlabelled: This study aims to analyze the agreement of cardiopulmonary variables between a cardiopulmonary exercise test with elastic resistance (CPxEL) and high-intensity interval exercise with elastic resistance (EL-HIIE).

Methods: Twenty-two physically independent participants were recruited. Visit one consisted of conducting a health survey and anthropometric assessment.

Acute Cardiopulmonary Response of High-Intensity Interval Training with Elastic Resistance vs. High-Intensity Interval Training on a Treadmill in Healthy Adults.

This study aims to describe and compare cardiopulmonary and subjective responses during high-intensity interval training with elastic resistance (EL-HIIT) and traditional high-intensity interval training (HIIT) sessions. Twenty-two healthy adults (27.6 ± 4.

Is There Agreement and Precision between Heart Rate Variability, Ventilatory, and Lactate Thresholds in Healthy Adults?

This study aims to analyze the agreement and precision between heart rate variability thresholds (HRVT1/2) with ventilatory and lactate thresholds 1 and 2 (VT1/2 and LT1/2) on a treadmill. Thirty-four male students were recruited. Day 1 consisted of conducting a health survey, anthropometrics, and Cardiopulmonary Exercise Test (CPx).

Cardiopulmonary Exercise Testing with Elastic Resistance: A New Reproducible Proposal for Determination of Ventilatory Thresholds and Maximum Oxygen Consumption.

To propose a new Cardiopulmonary Exercise Test with Elastic Resistance (CPxEL) and compare the physiological responses to conventional cardiopulmonary exercise test (CPx) performed on a treadmill. In addition, we tested the reproducibility of the CPxEL. Twenty-four physically active participants completed the CPx (first session) and CPxEL twice (second and third sessions) interspersed by seven days.

Profile of blood pressure and glycemic responses after interval exercise in older women attending (in) a public health physical activity program.

Background: and purpose: Interval exercise causes a positive impact on health status. Our aim was to evaluate the effects of a feasible and low-cost interval exercise on blood pressure and glycemic responses in people with controlled systemic arterial hypertension.

Methods: Thirteen women with hypertension (HG; age: 60.

Supervised walking improves cardiorespiratory fitness, exercise tolerance, and fatigue in women with primary Sjögren's syndrome: a randomized-controlled trial.

Objective: The aim of this study was to evaluate the safety and effectiveness of a supervised walking program in women with primary Sjögren's syndrome (pSS).

Methods: Forty-five sedentary women fulfilling the American European Consensus Criteria for pSS were randomized to a training group (TG, n = 23) or control group (CG, n = 22). Patients in the TG were submitted to supervise walking three times a week for 16 weeks.

Active and sedentary behaviours in children aged 7 to 10 years old: the urban and rural contexts, Brazil.

Background: Although the effects of physical activity (PA) on health and wellness are well-established, incorporating sedentary behaviours in the daily lives of populations from high- and medium-income countries is becoming increasingly common. Regardless of other factors, the area of residence can influence the physical activity level and sedentary behaviours. The aim of this study was to identify and analyse active and sedentary behaviours and factors associated with physical activity in two different geographical areas in south-eastern Brazil.

Heart rate at 4 s after the onset of exercise in endurance-trained men.

It has been suggested that the increase in heart rate (HR) at the onset of exercise is caused by vagal withdrawal. In fact, endurance runners show a lower HR in maximum aerobic tests. However, it is still unknown whether endurance runners have a lower HR at 4 s after the onset of exercise (4th-sec-HR).

Long-term intense resistance training in men is associated with preserved cardiac structure/function, decreased aortic stiffness, and lower central augmentation pressure.

Objective: There have been contradictory reports regarding resistance exercise and central arterial compliance. The American Heart Association has recommended its use in preventing/treating cardiovascular diseases. We examined the effects of long-term endurance running and intense resistance training on central hemodynamics, compared with healthy control (CON).

Nutritional extremes among school children in a rural Brazilian municipality.

Introduction: Latin America is undergoing rapid demographic and nutritional transitions with the accompanying tendency to overweight as is common in countries emerging from poverty. In Brazil, changes due to the nutritional transition have affected the whole population, both urban and rural. Overweight in a large number of Brazilian children is one of the greatest public policy challenges.

Cardiovascular risk factors, their associations and presence of metabolic syndrome in adolescents.

Objective: To evaluate the occurrence of metabolic syndrome (MS) and independent associated risk factors in adolescents in the city of Vitória, Brazil.

Methods: We assessed 380 adolescents aged 10 to 14 years attending public schools. Body mass index and blood pressure at rest were measured.

Blood pressure response to physical exertion in adolescents: influence of overweight and obesity.

Background: The acute blood pressure response to physical exertion has been used as an indicator of the risk of developing hypertension. The factors associated with this response need to be clarified for timely intervention in preventing hypertensive disease.

Objective: To describe the response of cardiovascular variables to acute physical exertion in overweight adolescents using cardiopulmonary exercise testing.

The association between cardiorespiratory fitness and cardiovascular risk in adolescents.

Objective: Maximum oxygen uptake is emerging as the measure of preference for expressing cardiorespiratory fitness for the purposes of surveys of physical activity, due to its greater objectivity and lower propensity to errors. Studies indicate that this measure is better correlated with cardiovascular diseases. This paper proposes to relate cardiovascular risk factors in adolescents with their level of cardiorespiratory fitness.

Maximum oxygen uptake in adolescents as measured by cardiopulmonary exercise testing: a classification proposal.

Objective: The identification of populational levels of maximum oxygen uptake (VO(2max)) is an aid to studies that propose to relate physical fitness to cardiovascular risk, and also for prescribing exercise and analyzing the effects of training. To date, there is no information with which this parameter can be classified in samples of adolescents from the Brazilian population. This study is, therefore, the first to propose the determination of mean VO(2max) levels in a sample of the Brazilian population.
