“…Dans une expérimenta-tion en caisson, Radermacher et al (1990) ont évalué l'effet d'un exercice d'intensité modérée (75 W pendant 20 min) réalisé au fond pendant 30 min à 6 ATA, en mesurant la cinétique d'élimination de l'azote dissous dans le sang veineux et la formation du bulles veineuses par doppler continu. Il ont constaté que l'élimination de l'azote n'est pas modifiée par l'exercice et que la détection de bulles circulantes reste négative dans les deux circonstances (plongée témoin et plongée avec exercice).…”

Exercise at depth and during decompression is a commonly accepted factor that affects the risk of decompression sickness in divers and aviators, but data documenting these effects are limited and conflicting. The mechanisms may be complex and influenced by several factors, such as the type and nature of exercise, the temporal course of the exercise in relation to the decompression procedure, and the diving profile. This paper reviews previous studies in this field of research, and discusses current concepts in diving activities.

“…Decompression sickness in divers is analogous to GBT in some ways because both are caused by bubble formation in tissues as a result of gas supersaturation. In humans, exercise during diving has been demonstrated to exacerbate (Van der Aue, Brinton, & Kellar, 1945), relieve (Dujić et al, 2005; Jankowski, Nishi, Eaton, & Griffin, 1997; Jankowski, Tikuisis, & Nishi, 2004), or have no effect (Jankowski et al, 2004; Radermacher et al, 1990) on symptoms of decompression sickness, depending on the type of exercise and its timing during the dive. There is also evidence from studies on animals such as rats and bullfrogs ( Rana catesbeiana , Whitaker, Blinks, Berg, Twitty, & Harris, 1945), crustaceans ( Pachygrapsus crassipes , Pagurus hirsutiusculus , and Pagurus samuelis , McDonough & Hemmingsen, 1984a, 1984b), channel catfish ( Ictalurus punctatus ), and woolly sculpin ( Clinocottus analis , McDonough & Hemmingsen, 1985) that locomotion promotes bubble formation in tissues during decompression and that bubbles form preferentially in limbs that move during decompression (McDonough & Hemmingsen, 1984a, 1984b).…”

Total dissolved gas (TDG) supersaturation from sources such as hydroelectric dams can cause harmful bubble growth in the tissues of aquatic animals, known as gas bubble trauma (GBT). Locomotion is known to exacerbate bubble growth in tissues during decompression under certain conditions (such as in diving animals), possibly because of increased bubble nucleation. As with decompression sickness, GBT is caused by the supersaturation of tissues with gas, and thus we hypothesize that locomotion promotes bubble nucleation in the tissues of fish exposed to TDG supersaturation. Many previous laboratory studies have tested the effects of TDG on fish exposed to low‐velocity, non‐directional flow, whereas fish in field conditions are exposed to higher‐velocity flows and are likely more active. Therefore, it is important to understand the effects of locomotion on GBT to apply laboratory results to active fish in field conditions. We exposed rainbow trout (Oncorhynchus mykiss) to either control (100% TDG) or TDG supersaturation (123% TDG) in either static or flowing water conditions (1.8 Bl/s) and recorded time to 50% loss of equilibrium (LOE). We observed no statistically significant difference in time to 50% LOE between flow conditions. Given the lack of statistically significant difference between static and flowing water, our findings indicate that results from GBT experiments on rainbow trout in non‐directional flow are applicable to more active individuals.
