Maximal expiratory pressure and Valsalva manoeuvre do not produce similar cardiovascular responses in healthy men.

What is the central question of this study? This is the first study to evaluate and describe the cardiovascular responses during maximal expiratory pressure compared with the Valsalva manoeuvre, and whether those responses are similar. What is the main finding and its importance? This study showed that the duration of the manoeuvres appears to be responsible for the different physiological mechanisms involved in the cardiovascular responses to each manoeuvre and that the intensity of expiratory effort was related to the response in maximal expiratory pressure. These results are important to identify the risks to which subjects are exposed when performing these manoeuvres.

Circulatory and Ventilatory Power: Characterization in Patients with Coronary Artery Disease.

Background: Circulatory power (CP) and ventilatory power (VP) are indices that have been used for the clinical evaluation of patients with heart failure; however, no study has evaluated these indices in patients with coronary artery disease (CAD) without heart failure.

Objective: To characterize both indices in patients with CAD compared with healthy controls.

Methods: Eighty-seven men [CAD group = 42 subjects and healthy control group (CG) = 45 subjects] aged 40-65 years were included.

Effect of hormone replacement therapy on cardiac autonomic modulation.

Objective: To investigate the effects of hormone replacement therapy (HRT) on heart rate variability (HRV) in healthy postmenopausal women.

Methods: Two groups were evaluated: group 1 (G1): 20 women not undergoing HRT (60 ± 5.89 years), group 2 (G2): 20 women undergoing HRT (59 ± 5.

Effects of excess body mass on strength and fatigability of quadriceps in postmenopausal women.

Objective: Obesity is a major public health problem leading to, among other things, reduced functional capacity. Moreover, obesity-related declines in functional capacity may be compounded by the detrimental consequences of menopause. The aim of this study was to understand the potential effects of excess body mass on measures of functional capacity in postmenopausal women.

Effects of infrared-LED illumination applied during high-intensity treadmill training in postmenopausal women.

Background Data: Technology and physical exercise can enhance physical performance during aging.

Objective: The purpose of this study was to investigate the effects of infrared-light-emitting diode (LED) illumination (850 nm) applied during treadmill training.

Materials And Methods: Twenty postmenopausal women participated in this study.
