Effects of exercise on bubble formation and survival
| Group | Allocation | Body weight (g) | Scan grade | Survival (min) |
|---|---|---|---|---|
| I | Exercise (48h prior to diving) | 315 ± 6 | 4 (3–5) | 35 (26–60)§ |
| Sedentary | 310 ± 9 | 5 (—) | 12 (4–20) | |
| II | Exercise (20h prior to diving) | 316 ± 9 | 0.5 (0–2)§* | > 60 (—)§* |
| Sedentary | 313 ± 8 | 5.0 (4–5) | 13 (2–47) | |
| III | Exercise (10h prior to diving) | 314 ± 9 | 5 (—) | 11 (3–15) |
| Sedentary | 318 ± 12 | 5 (—) | 14 (2–31) | |
| IV | Exercise (5h prior to diving) | 309 ± 8 | 4 (2–5) | 20 (10–60) |
| Sedentary | 312 ± 6 | 5 (3–5) | 23 (17–60) | |
| V | Exercise (30 min prior to diving) | 315 ± 8 | 5 (—) | 11 (3–23) |
| Sedentary | 317 ± 9 | 5 (—) | 8 (2–17) |
§
P < 0.001, significantly different from its respective control group.
*
P < 0.001, significantly different from all other goups. Note that rats registered as dead after 60 min were actually still alive at that point, but were killed after 60 min. Body weights are presented as mean ±s.d.; the rest of the data are given as median (range). Decompression time was 12 min for all groups.
