A person's target heart rate zone is between 50% and 85% of their maximum heart rate,according to the AHA. Most commonly, maximum heart rate is calculated by subtracting your age from 220. So for a 30-year-old person, for example, the maximum heart rate would be 190 bpm: 220 – 30...
For example, a 40-year-old's predicted maximum heart rate is about 180 bpm. You can learn your actual maximum heart rate with agraded exercise test. If you’re taking medicines or have a medical condition such as heart disease, high blood pressure, or diabetes, ask your doctor whether yo...
The maximal heart rate for a 30-year-old individual would be? (a) 220 bpm (b) 150 bpm (c) 190 bpm (d) 100 bpm Bradycardia means "___ heart." What causes pulse? If a patient has a cardiac output of 5.5 L/min and a heart rate of 87 beats/min, what is the stroke volume?
Sex—prior works have found differences in RHR between sexes with women having, on average, a higher RHR of 3–7 bpm32. Caffeine and alcohol consumption—we further adjusted for participants frequency of caffeine and alcohol consumption as both compounds have been found to be associated with incr...

is plentiful. When the partial pressure of oxygen is below 40 mmHg, oxygen saturation falls. Hemoglobin affinity for oxygen is decreased at these lower partial pressures. Lower partial pressures are found in metabolically active tissue. The oxygen is unloaded in these t...
