Influence of endurance and resistance exercise order on the postexercise hemodynamic responses in hypertensive women.

The study aims to evaluate the effects of the order of endurance and resistance exercises on postexercise blood pressure (BP) and hemodynamics in hypertensive women. Nineteen hypertensive women underwent 3 sessions: control (50 minutes rest), endurance (50-60% of heart rate reserve) followed by resistance exercise (50% of 1 repetition maximum) (E + R), and resistance followed by endurance exercise (R + E). Before and 30 minutes after each session, BP, peripheral vascular resistance, cardiac output, stroke volume, and heart rate were measured.

Isokinetic strength and endurance in proximal and distal muscles in patients with peripheral artery disease.

Background: The objective of this study was to analyze the muscle strength and endurance of the proximal and distal lower-extremity muscles in peripheral artery disease (PAD) patients.

Methods: Twenty patients with bilateral PAD with symptoms of intermittent claudication and nine control subjects without PAD were included in the study, comprising 40 and 18 legs, respectively. All subjects performed an isokinetic muscle test to evaluate the muscle strength and endurance of the proximal (knee extension and knee flexion movements) and distal (plantar flexion and dorsiflexion movements) muscle groups in the lower extremity.

Impact of a supervised strength training or walking training over a subsequent unsupervised therapy period on walking capacity in patients with claudication.

Previous studies have demonstrated that supervised strength training (ST) or walking training (WT) improve walking capacity in patients with claudication. However, it remains unknown whether these improvements would be sustained over a subsequent unsupervised period. This article reports the findings of a study to analyze whether the improvements in walking capacity, achieved with a supervised ST or WT, would be sustained over a subsequent unsupervised therapy period in patients with claudication.

Acute effect of resistance exercise intensity in cardiac autonomic modulation after exercise.

Background: Cardiac sympathovagal balance is altered after resistance exercise. However, the impact of the characteristics of resistance training in this response remains unclear.

Objective: Analyze the acute effect of resistance exercise intensity for trunk and upper limbs in cardiac autonomic modulation after exercise.

Cardiovascular responses to walking in patients with peripheral artery disease.

Purposes: The study's purposes were to assess the cardiovascular responses during constant-load walking and to identify predictors of this response in peripheral artery disease (PAD) patients.

Methods: Seventy-nine patients with PAD performed a constant-load treadmill test (2 mph, 0% grade). During the test, systolic blood pressure (BP), diastolic BP, and HR were obtained at the fourth minute to the last minute of exercise.

Abdominal obesity in adolescents: prevalence and association with physical activity and eating habits.

Background: Abdominal obesity in adolescents is associated with cardiovascular and metabolic diseases, but its prevalence and the factors associated with its occurrence are unknown.

Objectives: To determine the prevalence of abdominal obesity in adolescents, and to evaluate whether the indicators of physical activity and dietary habits are associated with the occurrence of abdominal obesity in adolescents.

Methods: The sample included 4138 high school students (14-19 years), selected by cluster sampling in two stages.
