Document Summary
Effect on economy of effort impacts cross-country skiing, short track speed skating, and bicycling. Running 1m behind another runner at a speed of 21. 6 km*hr-1 decreases total energy expenditure by about 7% As the intensity increases we need epinephrine and norepinephrine. When you"re walking fast enough running requires less energy than running. Estimates rdee as a function of age, mass, and height. If a runs faster than b at a given vo2 what is the best answer? a. b. c. d. A is more economical than b i. ii. Economy: what you got for the amount you spent. Efficiency: unit less. (work you do / total energy expended) With running you don"t know the total energy spent. What is true about the lactate threshold a. b. c. d. It occurs at the same intensity as vo2 max. Individuals who do heavy exercise with one leg will cause elevations in plasma e which circulates to all musce cells.
