Abstract

Energy requirement is assessed interms of energy expenditure of individuals or population groups, rather than energy intake. Energy expenditure of the body increases when the body and its organs are active. However, a certain minimum amount of energy is always needed for the maintenance of life, even during the period of rest and sleep. The metabolism under such a condition is referred to as "Basal Metabolism" and the minimum amount of energy needed for the maintenance of cellular metabolism, when the body is in the basal condition is referred to as BMR. Number of factors such as age, sex, body size, racial variation, hormones, climate, diet, body temperature and physiological state influence BMR. The present study was designed with the objective of finding the BMR and its relation to the somatic measurements of the agricultural workers of both the sexes.

Abstract

Nutritional anthropometry is the measurement of human body at various ages and levels of nutritional status. It is based on the concept that an appropriate measurement should reflect any morphological variation occurring due to significant functional physiological change. The relationship between nutrition and physical work efficiency has attracted attention of nutritionists all over the world because of its socio-economic implications. A number of parameters related to physical work efficiency have been measured among under-nourished populations. Physical work capacity measures the work output in the laboratory under artificial conditions. Indias main occupation is agriculture and a huge population (labour force) are involved in the food production front, Indian farmers are conservative, backward or indifferent. They are poor in health and nutritional status. Poor nutrition affects the work capacity and productivity. The present study was designed with the objective of finding out the relationship between body weight and physical work capacity among agricultural and non-agricultural workers of both the sexes.
