Exercise made the fat cells around the blood vessels in obese mice about 4.1% smaller than in mice that didn't exercise.

Evidence Quality Assessment

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study design is a randomized intervention in mice, but GRADE analysis indicates causation cannot be established for human application, so 'associated with' is appropriate.

Obese mice that exercised on a treadmill for 8 weeks weighed about 22.6% less than obese mice that didn't exercise.

93%

Exercise boosted levels of a protective anti-inflammatory protein in the blood vessels of obese mice by nearly five times compared to mice that didn't exercise.

79%

Exercise made a key metabolic regulator in the fat around blood vessels 2.45 times more active in obese mice compared to sedentary mice.

78%

When obese mice exercised, their blood vessels relaxed 19% better in response to a chemical that normally makes them widen, especially when the surrounding fat tissue was present.

78%

Even without the surrounding fat tissue, exercise helped obese mice's blood vessels relax 17% better when exposed to a chemical that promotes widening.
