Effects of 1-year exercise in patients with atrial fibrillation: study protocol for the Norwegian Exercise in Atrial Fibrillation (NEXAF) randomised controlled trial

Open Heart

Although lifestyle changes and risk factor modification are now acknowledged as central components of atrial fibrillation management, the effects of exercise on disease-specific outcomes are still not extensively documented due to few high-quality randomised trials.

Physiology Friday #251: Does Our Body Have a ‘Muscle Memory’ for Aerobic Exercise?

Physiologically Speaking

Muscle memory is a concept in exercise science that highlights the remarkable ability of muscles to "remember" prior training, allowing for quicker adaptations when retraining after a break. The concept of muscle memory is quite simple: It suggests that our body will have an enhanced response to a specific exercise stimulus (i.e.,

Comparative effectiveness of exercise interventions on arterial stiffness in individuals at risk for cardiovascular disease: a systematic review and network meta-analysis

Frontiers in Cardiovascular Medicine

BackgroundPrevious studies have shown that exercise can improve arterial stiffness (AS). However, it remains unclear which type of exercise is most effective for managing AS, particularly in individuals at high risk for cardiovascular diseases (CVD).

Physiology Friday #253: Low-carb Matches High-carb for Performance: Is it Time to Question the Obligatory Role of Glycogen for Endurance Exercise?

Physiologically Speaking

Adding to this controversy are questions about carbohydrate supplementation during exercise, particularly whether minimal carbohydrate intake can deliver performance benefits or if higher intakes are necessary to sustain energy levels and delay fatigue. And how effective is minimal carbohydrate supplementation during prolonged exercise?

Short, intense bursts of exercise more effective after stroke than steady, moderate exercise

Science Daily - Heart Disease

Significant improvements in aerobic fitness were noted after 12 weeks of high-intensity interval training sessions compared to traditional, moderate exercise sessions, according to a new study.

Physiology Friday #259: Do Antioxidants Hamper the Adaptive Response to Exercise?

Physiologically Speaking

Exercise is the picture-perfect example of hormesis. Whether it’s a long run or a heavy lift, exercise damages our cells in the short term. For resistance exercise, ROS support hypertrophy and strength by signaling through pathways like mTOR and IGF-1, pathways also inhibited by chronic antioxidant supplementation.

Comparative hemodynamic responses to upright and recumbent cycling in patients with exercise intolerance

Frontiers in Cardiovascular Medicine

Hemodynamic variables were measured at rest and across various exercise intensities.ResultsSignificant differences were observed in right atrial pressure (RAP), mean pulmonary artery pressure (mPAP), and pulmonary artery wedge pressure (PAWP) between upright and recumbent positions.
