Document Summary

32 % of canadian children are overweight or obese. This trend is due to the technology and not having to do manual labour. Atp-pc system: explosive , short term energy that last 0-10 seconds into exercise. Anaerobic: this lasts from 1-3 minutes into exercise. Aerobic: will take over after 3 minutes into exercise. Overall contribution of energy systems: depending on duration of activity, there is one system that supplies energy to do the word. Children have smaller anaerobic power output than adults: muscle mass is smaller (the more muscle you have, the more glycogen stores you have; thus you can do more work, absolute quantities of energy reserves are smaller for children. Growth and maturation: energy reserves increase, tolerance improves (as we age, we are able to tolerate lactic acid and we get better at buffering by products of using immediate energy reserves) Increase in mean and peak anaerobic as we age.
