Document Summary
The wr is relative to body mass on a cycle ergometer the resistance is applies by weights (kg). The test weight is equal to body weight x 0. 075 (e. g. 54 kg female; test weight = 54 x 0. 075 = Fatigue index (ppo lpo)/ppo x 100. Vo2 peak = 3. 66 l/min @ wr max = 223 w. Vo2 = (1100 * 10. 8/ 80) + 7. Energy required = 12. 44 * 5 kcal / lo2 (if that power output could be maintained, but it can"t) Dots at the bottom are vo2 measured during the wingate. 1. 25/12. 44 = 10% which is how much energy arrives from aerobic sources. There is a big decrease in atp about a 40% decrease. Within the 30 seconds these changes can be underestimated because a lot of the atp can be resynthesized in 30 seconds. Adp concentration in progressive usually increases but in submaximal there is not much change.
