This experimental study was designed to see and to predict oxygen uptake and heart rate in static working postures of male. The results based on this composative analysis were as follows: 1. There did not exist a near relationship between heart rate and oxygen uptake in the case of static working postures. 2. Oxygen uptake and heart rate seems to depend on the postural characteristics rather than the static workload. 3. Eeart rate and oxygen uptake was not sufficient as a siagle physiologican measure of the static workload. 4. The lowest heart rate was found in squatting, or in sitting posture, whareas the lowest oxygen uptake was found in sitting posture.
