Question

Describe an experiment to investigate the effect of training on subjects ability to run faster without respire get anaerobically

Answer 1

A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration 

Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy 
Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 

1.) Take a stop-watch 
2.) Take TWO or more runners 
3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up 
4.) make the runners breath hard for air 
5.) after finish line 
6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) 
7.) check the concerntration 
8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race
