Aerobic: with or in the presence of oxygen; an exercise activity at a low enough intensity to keep you and your muscles from running out of oxygen
Ambient
heart rate (Ahr): The Ahr is taken after you are out of bed
and have started your day. It can be taken while sitting or standing. It
normally varies very little from day to day. If it does vary, especially if it
goes up, it is a good indicator that your body is under some sort of stress.
Anaerobic: without
oxygen; an exercise activity that is performed at a high intensity and muscles
work without oxygen
Anaerobic threshold
heart rate (AThr)(lactate threshold): The
point at which your body is producing more lactic acid than can be metabolized.
Lactic Acid:
a waste product caused by the burning of glucose without
oxygen in a short period of time.
Maximum heart rate
(Mhr): The highest number of times your heart can
contract in one minute.
Recovery heart rate:
The reduction of your heart rate immediately after stopping
the exercise.
Resting heart rate
(Rhr): The number of times your heart beats when
it is a rest. You take your Rhr at the moment you wake up in the morning.
Steady state heart rate:
The heart rate, which is held at the same number throughout
exercise.
Zone: An area of intensity
(exertion) of exercise that is based on a percentage of your maximum heart
rate. Your intensity is measured in
beats per minute.
