In posing
the questions about human capability as a power source the duration of a
cycling event should be taken into account. A sprint event may use mainly anaerobic
work from the rider whereas a stage in the Tour de France is clearly
cycled under aerobic conditions.
In anaerobic work (work without oxygen)
ATP, the energy source for working muscle, is produced by decomposing stored
creatine phosphate or by breaking down carbohydrates in a glycolosis reaction.
In the aerobic reaction, glycogen, fats, and proteins are broken down
in the presence of oxygen to give ATP.
In designing your experimental
measurements, it will be important to make sure that you enter the aerobic condition
since this is most relevant to HPV propulsion over reasonable distances.
Look at data presented in the text before selecting a time period for your
measurement. The time coordinate is frequently presented with a logarithmic
scale and this might suggest the nature of time intervals at which performance
data should be recorded. |
