HBOT did not improve exercise performance immediately following exposure
| Clinical bottom line: 1. No evidence to suggest improved athletic performance after HBOT. |

Three-part Clinical Question: Does hyperbaric oxygen exposure acutely improve exercise performance?Search Terms: Exercise, Sport
The Study:Double-blinded concealed randomised controlled trial with intention-to-treat. The Study Patients: Physically active males Control group (N = 9 analysed): Normobaric air for 1hr at 1.2 ATA Experimental group (N = 9 analysed): 100% O2 for 1 hr at 2.0 ATA
The Evidence:
| Outcome | Control Group | HBOT Group | Difference | 95% CI | ||
| ^ | Mean | SD | Mean | SD | ^ | ^ |
| Time to Fatigue (s) **(Treadmill) |
84.4 | 20.0 | 77.3 | 14.7 | 7.1 | -10.4 to 24.6 |
| Heart Rate post exercise (Treadmill) | 173 | 12 | 172 | 16 | 1 | -12.9 to 14.9 |
| Rating of Exertion (/20) (Treadmill) | 18.3 | 0.9 | 17.9 | 1.2 | 0.4 | -0.6 to 1.5 |
Comments: 1. Small study with low power to show important differences. 2. Subjects were not high performance athletes. 3. Paper actually describes two small trials with no benefit shown in treadmill or benchpress performance
