Working Loads and Physical Functions of Modern Farmers in Japan.
Proceedings of the VII International Congress of Rural Medicine, Salt Lake City, Utah, September 17-21, 1978, International Association of Agricultural Medicine 1978 Sep:222-223
The effects of work load on physiological function in modern Japanese farmers were discussed. Due to seasonal variations in working hours and energy consumption in agricultural work, imbalances in food intake and expenditures of energy can result in decreases in body weight and lean body mass and chronic fatigue. Field studies on the amount of time worked and its effect on energy consumption, body weight, and hematological parameters such as hemoglobin, hematocrit, and serum protein concentration were discussed. These studies were conducted to assess the effects of mechanizing farm work. Results have shown that energy expenditure by Japanese farmers currently average about 500 kilocalories per day less than 30 years ago, when agriculture was not mechanized. Body weights of modern rice farmers are less than those of 30 years ago but are still higher than those of modern day sedentary workers. Seasonal changes in hematocrit values (not specified) still occur today as they did in the 1950s. The author concludes that mechanizing agricultural work has decreased the physical load and improved the health conditions of modern Japanese farmers.
