Doing regular exercise for 12 weeks helped improve heart and lung fitness in obese black South African women, as measured by their ability to use oxygen during exercise. This finding is from the abstract summary - full study details were not available

Scientific Claim

Exercise training was associated with an increase in maximal oxygen uptake (VO2peak) in black South African women with obesity, with a mean increase from 24.9 to 27.6 mL/kg/min (P < 0.001).

Original Statement

“Exercise training increased VO2peak (mean ± s.d.: 24.9 ± 2.42 to 27.6 ± 3.39 mL/kg/min, P < 0.001)”

From study:Effect of exercise training on insulin sensitivity, hyperinsulinemia and ectopic fat in black South African women: a randomized controlled trial.

Can suggest probability/likelihood

Assessment Explanation

The abstract uses definitive language ('increased'), but the study's guidelines recommend probabilistic language for RCTs due to potential blinding limitations.

Similar Assertions

Doing short bursts of intense exercise for 12 weeks doesn't improve the maximum oxygen your body can use during exercise in people with excess body fat, even though they can exercise longer before getting tired.
