Extra oxygen helps obese adults with type 2 diabetes produce muscle energy more quickly after exercise, as measured by oxidative phosphorylation rates.
Scientific Claim
Supplemental oxygen administration is associated with a 0.046 mmol/L/s faster oxidative phosphorylation rate in sedentary obese adults with type 2 diabetes during recovery from isometric calf exercise (P=0.027).
Original Statement
“the in vivo impairment in oxidative capacity resolved with oxygen supplementation in adults with diabetes (ADP depletion rate 5.0 s faster, P = 0.012; oxidative phosphorylation 0.046 ± 0.079 mmol/L/s faster, P = 0.027).”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study design is observational with no control group for oxygen, so causal language is inappropriate. The verb 'associated with' correctly reflects the evidence.
