Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
The ECG can detect sinus bradycardia, a resting heart rate of fewer than 60 beats per minute. This is often accompanied by sinus arrhythmia. The pulse of a person with athlete's heart can sometimes be irregular while at rest, but usually returns to normal after exercise begins. [12] [13] [14]
Depending on the intensity of the exercise, cooling down after a workout method, such as intense weightlifting, can involve a slow jog or walk. Cooling down allows the heart rate to return to its resting rate. Additionally cooling down may reduce dizziness for professional or serious athletes and vocal performers after strenuous workouts.

This is the intensity at which the heart and lungs can no longer provide adequate oxygen to the working muscles and an oxygen debt begins to accrue; at this point the exercise becomes anaerobic. Aerobic training intensity for most individuals is <85-92% of maximum heart rate.

Tom Brady shared his nutrition plan, the TB12 diet, in a book. A registered dietitian walks you through the plan and explains the pros and cons of the diet.
A reduction in stroke volume is the decline in the volume of blood the heart is circulating, reducing the heart’s cardiac output. [6] The stroke volume is reduced due to loss of fluids in the body, reducing the volume of blood in the body. [7] This leads the increase in heart rate to compensate for the reduced cardiac output during exercise. [6]
