Exercise 5

Describe how the economy of running might be evaluated in the laboratory.

Step 1 of 2

The economy of a particular sport event influences the energy cost of the sport and interacts with VO₂ max. An athlete who is economical spends less amount of energy than an uneconomical athlete. Therefore, to measure an athlete’s potential; the measurement of exercise economy is one of the useful parameters.

The energy expenditure is measured at several running speeds and a graph is plotted with running speed against energy expenditure to predict exercise economy. Quantification of economy of exercise is done by measuring the steady-state oxygen cost of a particular sport event.
