His heart is stronger as well as being significantly larger. Per pump (stroke, beat), his trained heart can output a greater volume of blood than an untrained person (let's called the untrained person Joe Normal). So at rest, both Armstrong and Joe need to move the same volume of blood around per minute to keep everything oxygenated. Each beat of Armstrong's heart is going to move twice as much blood as a beat from Joe's. As a result, Armstrong's heart only needs to beat half as often to keep things oxygenated. How did this happen? Lots and lots of cardiovascular training. As the heart gets trained, it gets stronger and larger - it is a muscle, just like your biceps grow after multiple bicep curls in the gym. When Lance is sprinting as fast as he can, his heart is not pumping much more often than when a non-athlete is sprinting - but it's pumping out more blood per beat so he can go further and faster since his muscles can remain better oxygenation, produce less lactic acid and take longer to fatigue.

∙ 15y agoThis is a resting heart rate measurement for Lance. Generally these are taken when the person is either lying prone or sitting motionless, more than often in the morning after waking. More importantly, it is because he is a well trained and conditioned athlete. A highly trained endurance athlete often has a larger heart that is like an enlarged muscle. The training and the fitness level leads to a slow resting heart rate. A rate of 32-38 is extremely common for Olympic calibre athletes and Tour De France athletes.

∙ 11y agoLow resting heart rate for athletes is very common because their heart has become very efficient in pumping blood. Efficiency in emptying out the ventricles more fully could be why his heart rate is lower. If he can pump more blood in one beat than an untrained person that means he would have to pump less times per minute to get the same amount of blood through out the systemic circulation. Another possibility, though i'm not sure about this one, his body may be better at substance exchange at the capillary network in the systemic circulation or at the level of the alveoli in the pulmonary ciruculation.

Similarities between breathing and your heart rate?
Your heart rate, or pulse, is the number of times your heart beats in a minute. Depending on your age and level of physical fitness, a normal resting pulse ranges from 60 to 80 beats per minute. Your breathing rate is measured in a similar manner, with an average resting rate of 12 to 20 breaths per minute. Both your pulse and breathing rate increase with exercise, maintaining a ratio of approximately 1 breath for every 4 heartbeats.
Does height affect pulse rate?
Height does not affect pulse rate kthanks.
What movies make your pulse rate go up?
Horror/suspense movies if they make you scared.
What is pulse position demodulation?
Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2M possible time-shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical Amplitude_modulation_compared_to_Pulse_position_modulation'systems, where there tends to be little or no multipath interference.Read more: Amplitude_modulation_compared_to_Pulse_position_modulation'This answer is lifted from response to "Amplitude modulation compared to Pulse modulation", so the original answerer gets credit for a great answer.
What converter digitizes sound waves into a series of numbers?
This process is called PAM [pulse Amplitude modulation] Sampling: here is a Shout-out for the actual PAM Sampling rate - meanwhile assume a PAM sampling rate of once per millisecond: this means that each millisecond the natural audio acoustic wave's Amplitude is sampled/determined and the Amplitude of this acoustic wave is Quantified by another process called Digitization.
What should your resting heart rate be at?
Your resting pulse is the rate of your pulse when you are resting (when your not doing exersice).
Is pulse rate of 166 normal?
That is not a normal resting pulse for humans.
Your pulse rate is 139 resting How bad is this?
If that's your resting pulse, call a doctor ASAP.
What happens to a person's pulse rate if their heart muscle becomes stronger does the pulse become quicker?
No. The resting pulse becomes slower. (Note, the top pulse rate for everybody is about the same ... the "exercise tolerance" comes from how much you can increase from your resting rate.)
What is Michael Phelps resting pulse rate?
38
Is a child's pulse rate high or lower then an adult resting pulse rate?
A child's pulse rate is higher then an adult as they do more exercise but if a child is resting then it will be lower hoped this helped :)
What is a resting pulse rate?
The average resting heart rate is 70-90 beats per minute. The heart of a physically fit person, with a resting heart rate of 50, beats 9,512,000 times less per year than an average person's heart with a resting heart rate of 70 beats per minute. The better shape you are in, the lower your resting heart rate will be.
Can sport lower your pulse rate?
While actually exercising will cause your pulse rate to increase, when you are fitter your resting rate will be lower than before.
An effective exercise program resting pulse rate should?
decrease
What is the danger in having a very high resting pulse rate?
Een
What determines if an individual has high fitness?
Low resting pulse rate.
What is recovery pulse rate?
The ability of the heart to recover after strenuous exercise. There is not really a rate because it is the ability of the heart to go from a workout pulse rate that may be two to three times higher than the resting, to the resting rate. Hope this helps. <><
