Title: [abstract] WEIGHT AND BODY COMPOSITION DURING 31 ATMOSPHERE (ATA) SATURATION DIVE.
Author: Thorp, JW; Seale, JL; Conway, JM; Rumpler, WV; Haberman, KJ; Doubt, TJ
Abstract: Body weight and composition changes were measured as part of a study to define nutrient requirements for divers in deep saturation dives. Thirteen divers were studied during 3 deep saturation dives in NMRI's Man Rated Chamber Complex. Each 28-day dive had 3 days of compression, 15 days at 31 ATA, and 10 days of decompression. A controlled diet provided 3600 Kcal and about 100 gm protein daily with 30% of energy from fat. Body fat was measured by underwater weighing before the dive and within 7 days after decompression. Deuterium space was measured as another indicator of lean body mass on the second day and the last day at 31 ATA. Means were: [table] TIME, WEIGHT (kg), BODY FAT (%), LEAN BODY (kg), D2 SPACE (kg);Before dive: 77.13, 17.16, 63.73, - ;Day 2 @ 31 ATA: 76.55, - , - ,48.01;Day 15 @ 31 ATA: 74.63, - , - , 46.50;End of dive : 74.52, 16.86, 61.95, - ; [end table]. While at 31 ATA, 10 divers lost weight (1.36 to 4.54 kg) ; two gained weight (0.45 and 0.90 kg); one had no weight change. Weight change was minimal during decompression. Both fat and lean body mass decreased. The divers were primarily dry, with relatively low exercise rates with temperature and humidity controlled to their reported comfort. The data indicate that the calories and nutrients consumed were slightly inadequate. For saturation dives with exposure to heavier work and thermal stress, higher caloric intake will be required. Different diets and strategies may be needed to increase caloric intake since these subjects did not complain of hunger, and frequently returned uneaten food.
