Dr. Dudley Sargent

step bench example: 70 kg subject; 0.3 m step; 30 steps per min for 10 minutes. Find: Force Distance Work Power

Force (70kg)(9.81N/1 kg) = 686.7 Newtons force Distance (0.3m)(30steps/1 min)(10min) = 90 meters Work (686.7 N)(90m) = 61803 Joules or 61.8kJ Power (61803)/((10min)(60s/min)) = 103 Watts

Stationary Cycle example 1.5 kg resistance; 6m per revolution; 60 rev per min; 10 min exercise Find: force distance work power

Force 1.5kg(9.81 N) = 17.7 N Distance (6 m/rev)(60 rev/min)(10min) 3600 m Work (17.7 N)(3600m) = 52920 J Power 52920J / (10min)(60sec) = 88.2 W

___ ___ studied: Role of CO2 in the control of breathing and developed respiratory gas analyzer

___ ____ studied the relationship of oxygen consumption and lactic acid in muscle
