Abstract

The present study was conducted to determine nutritional requirements during extensive physical training by sailors of Indian Navy. A total of 37 sailors who were undergoing physical trainers course at training establishment of Indian Navy participated in this study. Energy expenditure, energy intakes, nutrient status and body composition changes during one month of training were recorded. Mean energy expenditure was found to be 4035 ±733 kcal/day and an average intake of 4478 ±340 kcal/day with sufficient amount of micro and macronutrients. The level of vitamin and minerals in blood and their excretion were in the normal range. Body composition was also maintained with a marginal decrease in body fat content. Increase in grip strength of passive hand was observed (Basal: 41.5 ± 8.8 kg, after 1 month of training: 46.5 ± 6.1 kg). Results indicate adequate nutritional support from the diet and positive effects of the training on health
