Six interactive videodisc lessons for college-level exercise physiology
classes were developed. The six lessons were written using TenCore for the
IBM M-Motion technology. The focus of the laboratories is on exercise
metabolism measured by indirect calorimetry. The six lessons are as
follows. 1) Environmental measures: determines whether conditions are
favorable for exercise. Dry bulb, wet bulb, and black globe temperatures
are obtained to calculate relative humidity, STPD gas volumes, and the wet
bulb-globe temperature index. 2) Basal metabolism: emphasizes the mechanics
of calculating energy expenditure through indirect calorimetry. Lying,
sitting, and exercise metabolism are compared. 3) Submaximal metabolism:
compares the energy cost of walking a mile and running a mile. Steady-state
exercise, oxygen debt, and oxygen deficit are explored. 4) Maximal
metabolism: assesses maximal oxygen consumption using the Bruce protocol.
5) Hormonal responses to prolonged exercise: demonstrates the effect of
hormonal levels on %fat and %carbohydrate utilization during 1 h of
exercise. 6) Metabolic responses to supramaximal exercise: estimates
anaerobic power using the Wingate test.
