Your pulse rate is the number of times your heart beats per minute12.A "normal" pulse rate depends on your age and current level of fitness2.The average resting heart rate for most adults, including senior citizens, is between 60 and 100 beats per minute1.Young children tend to have high...
Press the tips of your index and middle fingers lightly to your skin until you feel your pulse. Then, count the number of beats for 15 seconds and multiply by four. That's your heart rate. You can do this whenever you need a quick heart-rate check. ...
A 60-year-old woman with a history of hypertension, diabetes and renal disease presented to the hospital complaining of diffuse weakness for 24 hours. On examination, vital signs showed a normal temperature, pulse 100 beats/min, respiratory rate 25 breaths/min, pulse oximetry 97%, blood pressur...
Your maximum heart rate is, on average, the highest your pulse can get. One way to get a rough estimate of your predicted maximum is to subtract your age from the number 220. For example, a 40-year-old's predicted maximum heart rate is about 180 bpm. ...
Sustained aerobic exercise at the old maximum heart rates that don't take into account gender is impossible and very likely dangerous. The pulse that should be aimed for during aerobic exercise is typically far less than old calculations.
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 ti...
The exercise was performed for a period of 300 s, less if the participants were compelled to stop owing to fatigue. The recovery pulse was recorded as the bpm during the 1 min after completing the test. Prior to each test, heart rate monitors (Polar H1, Polar Electro; Kempele, Finland)...
pulse laser irradiation with sub-nanosecond laser pulses (a central wavelength of 533 nm, a pulse duration of 0.5 ns, a pulse repetition rate of 1.5 KHz, and an average power of 20 μW) generated by a passively Q-switched laser (PULSELAS, ALPHALAS, Gottingen, Germany). To laterally ...
Sustained aerobic exercise at the old maximum heart rates that don't take into account gender is impossible and very likely dangerous. The pulse that should be aimed for during aerobic exercise is typically far less than old calculations.
"However, this should be used with caution, because heart rate can vary widely between individuals", says Todd Buckingham, PhD, lead exercise physiologist at Mary Free Bed Sports Rehabilitation Performance Lab. "This might be what an 'average' 40-year-old maximum heart rate is, but there are...
