Title: [abstract] NUTRITION FOR A 350 MSW WORKING DIVE.
Author: Paciorek, JA
Abstract: Weight Loss has often been reported in divers during deep saturation dives. Results from detailed metabolic studies on ten subjects at AMTE (PL), at depths greater than 300 msw indicated that each diver had an increased protein catabolism. There was no apparent concomitant protein anabolism which resulted in a measurable negative nitrogen balance and steady loss of Lean body mass whilst living in the hyperbaric environment. The working dive reported here showed that although each diver experienced a reduction in appetite and a greatly increased work-load, the implementation of a high protein-kilocalorie diet maintained body weight. A pre-dive five day study of the eating and drinking patterns of eight professional divers was conducted by measurement of all dietary intake. This formed an assessment of the type and amount of nutrients consumed. by each man while onshore and performing pre-dive fitness trammg. During the 17 day working dive the six selected men had a free choice for all meals except dinner selected from a set menu. High energy snacks and drinks were tested during the working phase of the dive as additional sources of energy in the event of HPNS nausea and loss of appetite. Nutritional status of each diver was monitored by plasma protein, albumin and glucose levels, which remained stable throughout the dive. Monitoring of red cell indices and electrolytes was used to assess the hydration state of each diver. All food and fluid intake during the dive was recorded. Twice weekly weight measurements of each diver showed no reduction in body weight during the dive or post-dive. This poster will present the type of diet used (0.225 MJ/kg body weight) by each diver to meet his daily nutritional requirements of a 8 hour work schedule for 6 days at 350 msw and still maintain a pre-dive blood biochemistry profile.
