Pushing Yourself and Family


The principle is called Overload

To improve fitness one has to push beyond the normal activity in order to improve Vigorous activity even in small amounts improves overall health. Now for  sedentary people some doing anything will be of benefit, becomes something is better than nothing. For others who are active to improve physical fitness you have to push to the edge of the comfort zone. Important the no pain no gain rule does not apply! 

 Here are a few tips from the CDC on how to measure intensity. 

How do I know if my child’s aerobic activity is moderate- or vigorous-intensity?

Here are two ways to think about moderate- and vigorous-intensity:
  1. As a rule of thumb, on a scale of 0 to 10, where sitting is a 0 and the highest level of activity is a 10, moderate-intensity activity is a 5 or 6. When your son does moderate-intensity activity, his heart will beat faster than normal and he will breathe harder than normal. Vigorous-intensity activity is a level 7 or 8. When your son does vigorous-intensity activity, his heart will beat much faster than normal and he will breathe much harder than normal.
  2. Another way to judge intensity is to think about the activity your child is doing and compare it to the average child. What amount of intensity would the average child use? For example, when your daughter walks to school with friends each morning, she’s probably doing moderate-intensity aerobic activity. But while she is at school, when she runs, or chases others by playing tag during recess, she’s probably doing vigorous-intensity activity. 


Measuring Physical Activity Intensity

Here are some ways to understand and measure the intensity of aerobic activity: relative intensity and absolute intensity.

Relative Intensity

The level of effort required by a person to do an activity. When using relative intensity, people pay attention to how physical activity affects their heart rate and breathing.

The talk test is a simple way to measure relative intensity. As a rule of thumb, if you’re doing moderate-intensity activity you can talk, but not sing, during the activity. If you’re doing vigorous-intensity activity, you will not be able to say more than a few words without pausing for a breath.

Absolute Intensity

The amount of energy used by the body per minute of activity. The table below lists examples of activities classified as moderate-intensity or vigorous-intensity based upon the amount of energy used by the body while doing the activity.
