1. We discussed methodologically the practical procedure to estimate and analyse qualitatively the physical load by heavy muscular labor. 2. From the view-point of medical practice in industrial health, we originated several new methods which were probably useful for analysis of the physical load by muscular labor. These methods were as follows: a) the graph showing work time distribution regarding the heaviness of muscular labor b) the original method to indicate the physiological characteristic of hot work environment c) the partitive estimate of heat balance at heavy work in hot environment d) Q-T index, an integrating value of heat storage. 3. Our labor investigations with several inportant jobs in iron works were carried out in suchs steps as follows: a) survey of working condition b) physiological study of physical effect by muscular labor c) diagnosis of "fatigue type" d) planning for improvement of working condition. 4. Two cases of our investigations on muscular labor were briefly stated. The one was a fatigue study on steel plate making job, and the another was a comparative observation on steel plate making and crane operating jobs with special reference to their qualitative difference.
