- 1Are maximal fat oxidation rates influenced by the exercise mode?Yes, maximal fat oxidation is significantly higher during running than with the same intensity of cycling
- 2A respiratory quotient of 0.7 indicates 100% oxidation of which substrate/s?Fat
- 3Are there gender differences in fuel oxidation?Yes, women oxidize more fat than men at low to moderate activities
- 4During high intensity exercise (85% of maximal oxygen uptake (VO2max)), in a fasted state, most of the energy need is provided by oxidation of............Muscle glycogen
- 5During low intensity exercise (25% of maximal oxygen uptake (VO2max)) in a fasted state, most of the energy needs are provided by oxidation of ....Plasma free-fatty acids
- 6During moderate intensity exercise (65% of maximal oxygen uptake (VO2max)) in a fasted state, most of the energy need is provided by oxidation of........Plasma free-fatty acids & muscle triglycerides
- 7Energy derived from muscle adenosine triphosphate (ATP) stores suffices to supportexercise that lasts ......few seconds
- 8High intensity intermittent exercise has been lately proposed as the exercise protocolthat might more effectively induce...Fat loss
- 9How much energy is expended for every litre of oxygen consumed?4.8 kcal
- 10In a rested state, an average person consumes about 3.5 ml of O2 per kg body massper minute, which is about......1 kcal/kg/hour
- 11In adult daily life, which organ consumes most of the energy (kcal/day)?Muscles
- 12In healthy subjects with a physical activity level equivalent to that of the general population, most of the daily energy expenditure is spent on.......Resting metabolic rate
- 13In healthy subjects, most of the energy expended during the rested state is derivedfrom....Fat
- 14Increasing prolonged everyday physical activity level to high levels in overweight andobese men produces........No change in ad libitum energy intake
- 15The aerobic pathway provides ATP by metabolizing........Proteins, carbohydrates & fat
- 16The inability to maintain a desired level of performance (fatigue) is usually referred toas 'hitting the wall'. Which substrate/s decreases severely at this point .......Glucose
- 17The longer the time spent exercising, the higher the contribution of .........Fat
- 18The RMR (expressed in kcal/kg/h) is........a. Lower in overweight than in normal weight subjects
b. Higher in men than in women
c. Lower in older than in younger adults
d. All of the above - 19Which macronutrient/s can generate ATP anaerobically as well as aerobically?Carbohydrates
- 20Women oxidize proportionally........More lipid, less carbohydrate, and less protein during moderate-intensity long-duration exercise than men.
