e actually declines over time and yet
dbs3sa 发表于 2012/9/20 9:56:00

There are two ways that a workout can be ruined – one is by “overdoing it” and the other is by failing to achieve established goals. For example,puma cheap sale, many regular exercisers and athletes will use a heart rate monitor to ensure that they are keeping pace with their anticipated levels of performance.

Heart rate monitors are such a common tool, in fact, that many popular machines and devices have them actually incorporated into such things as handgrips or computers. For instance,puma shoes cheap, it is not at all unusual for a modern treadmill to have several little plugs for the user to attach headphones or a heart rate monitor. There are even advanced options that will adjust the tension or speed of some devices according to the data being received by a heart rate monitor as well.

Why is heart rate such a significant issue? It helps to understand how the body and the heart react to increased levels of exertion and activity. The heart is the major pump that sends substances such as oxygen to the muscles and organs of the body. When someone begins to exercise, their muscles instantly ask for more oxygen and this causes the circulatory system and the heart to work together to deliver it. Over time,air jordans, the heart and circulatory system are able to deliver optimal amounts of blood and oxygen during times of exercise and this allows the “pump” to slow down or beat less per minute of exercise.

So, someone who is just beginning to exercise on a regular basis will see that their heart rate actually declines over time and yet their ability to exercise longer and harder will constantly improve. This is the sign of excellent health, and it should be monitored and tracked to ensure it remains so.

In addition to using heart rate monitors on such devices as treadmills to gauge the strength and cardiovascular health of the individual,nike shox, the monitors can also show if someone is overdoing it as well.

This is something that requires the use of a freestanding heart rate monitor, and asks the individual to document their heart rate when they first awake in the morning. Most health experts would require the monitor to be used while the individual is still lying in bed, and such a measurement is the “at rest” heart rate. As time passes and a person exercises more and more, this heart rate should actually decrease. Should readings begin to indicate a rise in the “at rest” rate of a regular exerciser it is usually a sign of overexertion and should be taken very seriously.
