105. ENERGY COST OF PROGRESSION: MAN (Continued) 



The oxygen requirement per minute for a given rate of energy expenditure may exceed the oxygen uptake during any 

 given minute if an oxygen debt is being accumulated, resulting in very high values for level running and swimming. 

 Values in parentheses are calculations, assuming one liter of O2 = 5 Calories. Values for all subjects listed as 

 weighing 70 kg are proportional calculations from values for subjects of other weights. 



/2/ Grade = 5% for each 2.9° of incline. /3/ O2 debt included in values given for this subject. /4/ O2 determination 

 from total O^ uptake in work and recovery.
