Sport as Therapy
Introduction: Sufficient hydration of a SCUBA diver is important to reduce the risk of decompression sickness. Mechanisms of fluid loss in diving and immersion are known, but not quantified. We aimed at relating dive profiles and individual parameters to fluid loss in order to develop an estimation...

Before and after the dives, body weight, bio data and dive profiles were recorded.Results: Average dive profile was 22.9 meters and 46.5 minutes, average weight loss was 0.8 kg after repetitive dives and 1.0 kg (1.2% relative body weight) after the first dive of the day.
