HHP 3114 Exam 1 | Questions with 100% Correct Answers Using an insulated, airtight chamber with walls containing copper tubing which water is passed to asses total body energy expenditure is called direct calorimeter Indirect calorimetry is a technique for metabolic rate measurement and involved the measuring of metabolic oxygen consumption The respiratory exchange ration (RER) is defined as the ratio between the ____________________________. amount of CO2 released and the amount of O2 consumed during metabolism Calculating kcal/day can be accomplished by _______________________. liters of O2 consumed per day times kcal used per liter of O2 Basal metabolism is the minimal 240hour energy expenditure for ______________. basic body functions Increases with increased body temperature BMR The best indicator of cardiorepiratory endurance is VO2 max treadmill test Lactate threshold is defined as that point in time during exercise of ____________ intensity when the rate of lactate production ____________ the rate of lactate _______________ or ____________. increasing, exceeds, clearance, removal Lactate threshold is a good predictor of _____________ distance running performance Individuals who are efficient runner tend to use ____________ oxygen when running at a given speed, compared to individuals who are inefficient runners Less Factors critical for success in endurance performance include what? a high vo2 max, a high lactate threshold, and a high economy A lactate threshold at 80% VO2max suggests __________________ aerobic exercise tolerance than at a threshold of 60% VO2 max greater A person with a high vo2 max (subject A) and a person with a low vo2 max (subject b) perform at an 8 minute pace. Which of the following is incorrect? Subject a is more aerobically fit than B Subject B, can perform the 8 min pace with less effort (lower submax vo2) assuming similar economy Fatigue due to failure to deliver adequate energy, accumulation of metabolic by-products, or failure of the muscle fiber's contractile mechanism is termed Peripheral fatigue Which of the following would likely account for the fatigue experienced by a marathon runner glycogen depletion and hypoglycemia Direct calorimetry is the most commonly used method for assessing energy expenditure during exercise False Maximal oxygen uptake is regarded as one of the best indicators of one's capacity for endurance exercise True Accumulation of lactate in the blood is determined by the balance between lactate production and lactate clearance True Lactate threshold generally occurs at a higher percentage of VO2 max in endurance training individuals than in untrained individual True Which of the following is not considered a fuel nutrient? Carbohydrates Fat Water Protein Carbohydrate is stored in the body as Glycogen Energy is needed for growth and repair of tissue, active transport of substances across cell membranes, muscle contraction, and force production The higher the intensity of the exercise, the more the body relies on carbohydrate as an energy source
