HBO pre-treatment after muscle fatigue testing was beneficial for sustained force production in a subsequent fatigue test.
|
Clinical bottom line: 1. HBO pre-treatment before a fatigue test was beneficial with a smaller decrease in maximal torque following the test compared to the same procedure but breathing air. |

The Study:Single-blinded concealed randomised controlled trial with intention-to-treat.
The Study Patients: Healthy young male volunteers.
Control group (N = 10; 10 analysed): Following baseline testing before and after a fatiguing isometric test of plantar flexion, subjects breathed air at 1.2 ATA for 70 minutes, and were then tested again before and after a fatigue test.
Experimental group (N = 10; 10 analysed): As above but subjects breathed 100% oxygen at 2.5 ATA for 60 minutes.

Comments:
1. Complex muscle EMG and twitch interpolation tests were performed. Essentially there were no clearly important advantages found with HBO exposure.
2. Small study where the baseline reductions in strength after fatigue test prior to experimental exposure were already greater in the control group - there is a possibility of bias toward the HBO group in the main outcome.
3. Authors suggest HBO could be useful in sports involving repeated jumping.
