Doing a mix of walking, strength, and balance exercises three times a week for two months likely improves blood vessel function in older adults who are overweight by increasing nitric oxide. This finding is from the abstract summary - full study details were not available
Scientific Claim
An 8-week multicomponent exercise program (aerobic, resistance, and balance exercises three times weekly) likely increases nitric oxide levels (p=0.01) in 40 overweight older adults.

Assessment Explanation
The study is an RCT, but small sample size (n=40) and unknown blinding status limit confidence. Definitive verbs like 'increases' are overstated; 'likely increases' or 'associated with' is more appropriate.
