Physiology Friday #254: Fueling for Performance and Health: Lessons from a Recent Low-Carb vs. High-Carb Study in Athletes

Physiologically Speaking

1 If you want the tl;dr, here it is: After 6 weeks on either a low- or high-carb diet, athletes experienced similar performance outcomes during a time-to-exhaustion test , a result that vindicates low-carb diets once and for all. Nonetheless, the findings are one data point that should cause us to think differently about exercise metabolism.

Physiology Friday #199: High-Intensity Interval Training Reduces Coronary Artery Plaque

Physiologically Speaking

Exercise prevents and reverses cardiovascular disease, but whether high-intensity exercise training (HIIT) is safe and effective for adults after minimally invasive heart surgery is unknown. Exercise is a wonder drug for cardiovascular disease (CVD) prevention and reversal. And the more you exercise, the better your outcomes.

GE Healthcare Launches New Cardiac PET tracer

DAIC

PET is the most effective form of MPI for detecting CAD iii and is recommended for a wide range of patients, including those considered more challenging to diagnose, such as individuals with a BMI greater than 30 or women, especially those with dense breastsi v , over SPECT MPI.

Physiology Friday #200: Higher Aerobic Fitness is Tied to Slower Biological Aging

Physiologically Speaking

Physical fitness was measured using VO2 peak obtained during a maximal exercise test (the gold standard way to measure this outcome). Furthermore, higher oxygen consumption at the ventilatory threshold — an indicator of submaximal exercise capacity, was also associated with lower biological aging.

Physiology Friday #197: Do Morning Workouts Maximize the Cardiometabolic Benefits of Exercise?

Physiologically Speaking

[link] Of course, diet is an important component of metabolic health, but exercise also plays an indispensable role. Not only does exercise help to maintain a healthy weight and/or promote weight loss, but it can also keep cardiometabolic risk factors in check in the absence of weight loss. A 5-minute cooldown ended each session.

Obesity in heart failure with preserved ejection fraction: Insights from the REDUCE LAP?HF II trial

European Journal of Heart Failure

Patients with more severe obesity were more likely to have responder characteristics for atrial shunt therapy (fewer pacemakers and lower exercise pulmonary vascular resistance [PVR]). of patients had BMI ≥30 kg/m 2. Strain measurements in all four chambers were maintained as BMI increased. Overall, 60.9%
