A scientist by the name of Francis Arthur Bainbridge reported this reflex in 1915 when he was experimenting on dogs. Bainbridge found that infusing blood or saline into the animal increased heart rate. This phenomenon occurred even if arterial blood pressure did not increase.
Different physical activities cause the heart to beat at different rates. Moderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old. Increasing your heart rate to 60 to 70 percent of maximum improves cardiovascular endurance and burns fat.oderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old.
