It is now practical to measure running economy. As with any performance variable once it is able to be measured it is more easily understood and prescriptive programs formulated. Why bother? We should aim to make the most of our training efforts, across each discipline. Training for adventure racing and multi-sport is time consuming, tiring and expensive. Surely, we owe it to ourselves to train smartly, to cover bush trails between kayak and MTB legs in the least painful and energy conserving manner? This, from the Institute of Sport (UK) on running economy.
“Economy is measured during the aerobic endurance test on the treadmill and is expressed simply as the volume of oxygen (VO2), relative to your body weight (ml/kg/min), that your body requires in order to run at a submaximal speed. It is a measure of the “cost of the body’s movement” during each stage of the test. Improving your economy would result in a decrease in this cost of movement. This would result in a smaller amount of oxygen being required to run at a given speed. Running economy can differentiate between runners that have very similar VO2 max values but different performance times and athletes with poor economy should aim to improve this aspect of their fitness.
