'''HBOT may improve symptomatic but not objective measures of recovery from exercise-induced muscle damage.''' 

'''Clinical Bottom Line:''' 
1. Some evidence of more rapid resolution of subjective pain and unpleasantness with HBOT at 5 days after exercise -induced muscle injury. 
2. No objective evidence that HBOT accelerated recovery as indicated by a range of tests including strength and MRI findings.

'''Three-part Clinical Question:''' For patients with exercise-induced muscle damage does hyperbaric oxygen therapy, compared to a sham treatment, result in a more rapid recovery from exercise-induced muscle damage? 
'''Search Terms:''' Athletic injuries, exercise recovery 

'''The Study:''' 
Double-blinded randomised controlled trial with intention-to-treat. 
'''The Study Patients:''' Healthy male students, not on anti-inflammatory medication and with no history of severe injury, recent pain or weight training in the gastrocnemius muscle. All underwent an exercise regimen designed to cause damage in the right gastrocnemius muscle. 
'''Control group''' (N = 6; 6 analysed): 3 sham treatments in monoplace chamber (atmospheric air at 1.3 ATA for 60 minutes) at 3 to 4, 24 and 48 hours after muscle damage. 
'''Experimental group''' (N = 6; 6 analysed): HBOT in monoplace chamber (100% oxygen at 2.5 ATA for 60 minutes) at same times as sham. 

'''The Evidence:''' 

{|
| '''Measure''' || '''Sham Group Mean''' || '''SD''' || '''Experimental Group Mean''' || '''SD''' || '''Difference''' || '''95% CI''' 
|-
| '''Pain/unpleasantness score at day 5 (% maximal)''' || 56 || 27 || 23 || 17 || 33 || 3.41 to 62.59 
|-
| '''Peak isometric torque at day 1 (% baseline)''' || -16 || 8 || -4 || 5 || -12 || -21 to -3 
|-
| '''Gastrocnemius cross sectional area (% baseline)''' || 5 || 2.5 || 6 || 3.5 || -1 || -4.91 to 2.91 
|-
|}

'''Comments:''' 
1. Methodologically sound but difficult to interpret all outcomes. 
2. Many results are expressed as percentage change from a baseline measurement taken prior to muscle damage. This might conceal differences in the extent of muscle damage. In this context, note significantly larger reduction in peak torque in sham group. 
3. Our results are estimations from graphs rather than published data. 
4. Results earlier than 5 days may be of more relevance to elite athletes.
