BACKGROUND: Menopause is associated with increased risk of cardiovascular disease and the causal factors have been proposed to be the loss of estrogen and the subsequent alterations of the hormonal milieu. However, which factors contribute to the deterioration of cardiometabolic health in postmenopausal women is debated as the menopausal transition is also associated with increased age and fat mass. Furthermore, indications of reduced cardiometabolic adaptations to exercise in postmenopausal women add to the adverse health profile...

Spinal cord injury (SCI) reduces physical activity and alters descending supraspinal cardiovascular control, predisposing this population to early onset of cardiovascular disease. We used a T3 SCI rodent model to investigate the effect of early vs. delayed passive hind-limb cycling (PHLC), as well as the effect of detraining on cardiac dysfunction and blood pressure control, including autonomic dysreflexia (AD). 20 male Wistar rats were divided into an early PHLC initiation group followed by a period of detraining (PHLC starting day 6 post-SCI, for 4 weeks, followed by 4 weeks of detraining; "early PHLC/detraining" group) and a delayed PHLC intervention group (no PHLC for first 5 weeks post-SCI, followed by PHLC for 4 weeks; "no PHLC/delayed PHLC" group)...

Different modes of exercise, disease, and training status can modify endothelial shear stress and result in distinct effects on endothelial function. To date, no study has examined the influence of type 2 diabetes (T2D) and training status on the acute endothelial response to different modes of interval exercise (INT). We examined the effect of a single session of resistance- and cardio-based INT compared with a time-matched control on endothelial function in 12 age-matched T2D participants, 12 untrained, and 11 trained adults (aged 56 ± 7 yr)...

BACKGROUND: Lifestyle interventions targeting physical activity, sedentary time and dietary behaviours have the potential to initiate and support behavioural change and result in public health gain. Although men have often been reluctant to engage in such lifestyle programs, many are at high risk of several chronic conditions. We have developed an evidence and theory-based, gender sensitised, health and lifestyle program (European Fans in Training (EuroFIT)), which is designed to attract men through the loyalty they feel to the football club they support...

Improved cancer survivorship has resulted in a growing number of Canadians affected by cancer and cardiovascular disease. As a consequence, cardio-oncology programs are rapidly emerging to treat cancer patients with de novo and preexisting cardiovascular disease. The primary goal of a cardio-oncology program is to preserve cardiovascular health to allow the timely delivery of cancer therapy and achieve disease-free remission. Multidisciplinary programs in oncology and cardiology have been associated with enhanced patient well-being and improved clinical outcomes...

This paper is devoted to the problem of regulating the heart rate response along a predetermined reference profile, for cycle-ergometer exercises designed for training or cardio-respiratory rehabilitation. The controller designed in this study is a non-conventional, non-model-based, proportional, integral and derivative (PID) controller. The PID controller commands can be transmitted as biofeedback auditory commands, which can be heard and interpreted by the exercising subject to increase or reduce exercise intensity...

KEY POINTS: Strenuous endurance exercise induces transient functional and biochemical cardiac perturbations that persist for 24-48 h. The magnitude and time-course of exercise-induced reductions in ventricular function and increases in cardiac injury markers are influenced by the intensity and duration of exercise. In a human experimental model, exercise-induced reductions in ventricular strain and increases in cardiac troponin are greater, and persist for longer, when exercise is performed within the heavy- compared to moderate-intensity exercise domain, despite matching for total mechanical work...

BACKGROUND: Within a controlled laboratory environment, high-intensity interval training (HIT) elicits similar cardiovascular and metabolic benefits as traditional moderate-intensity continuous training (MICT). It is currently unclear how HIT can be applied effectively in a real-world environment. PURPOSE: To investigate the hypothesis that 10 weeks of HIT, performed in an instructor-led, group-based gym setting, elicits improvements in aerobic capacity (VO2max), cardio-metabolic risk and psychological health which are comparable to MICT...

Aluminium phosphide (ALP) is one of the most commonly used pesticides worldwide with high mortality rates. Cellular damage and cardiorespiratory failure are the most common causes of mortality and morbidity after poisoning. It is supposed that giving enough time to the patient to survive, the most critical hours after exposure may help the cardiovascular system to recover itself and save the patient's life. During a training workshop for medical extracorporeal membrane oxygenation (ECMO), a 28-year-old ALP-poisoned male was referred to us...
