NTR 555 Final Exam with Potential Questions and Answers

NTR 555 Final Exam with Potential Questions and Answers The densitometric technique to measure body density using air displacement is a. barometric pressure b. air plethysmography c. air conditioning d. underwater weighing e. bioelectrical impedance ANSWER air plethysmography Bioelectrical impedance measurement of body composition relies on all of the following principles EXCEPT... a. The relative body fat in lean athletic people tends to be overestimated with bioelectrical impedance because of the nature of the equations used. b. Electrical conduction through the tissues between electrodes depends on the water and electrolyte distribution in that tissue. c. The amount of current flow through the tissues reflects the relative amount of fat contained in that tissue. d. Electrical conductivity is much greater in the fat mass than in the fat-free mass. ANSWER Electrical conductivity is much greater in the fat mass than in the fat-free mass Maximizing the fat-free mass of the athlete is desirable for athletes involved in activities that require strength, power, and muscular endurance. An example is ... a. long distance runner b. an ice skater in the paris competition c. a football lineman (american)
