Scientific Claim

Exercise training was associated with an increase in insulin sensitivity (S_I) in black South African women with obesity, with values rising from 2.0 to 2.2 (mU/l)−1 min−1 (P = 0.005).

Original Statement

“Exercise training increased S_I (2.0 (1.2–2.8) to 2.2 (1.5–3.7) (mU/l)−1 min−1, P = 0.005)”
