Cardiorespiratory fitness and fat oxidation during exercise in Chinese, Indian, and Malay men with elevated body mass index

Applied Physiology, Nutrition, and Metabolism, Ahead of Print. A cross-sectional pilot investigation was performed in Chinese, Indian, and Malay men (15 each) with elevated body mass index to compare (i) cardiorespiratory fitness (CRF) and (ii) fat oxidation at rest and maximal fat oxidation during exercise. Predicted CRF (Chinese: 37.0 (5.1)  mL·kg–1·min–1; Indian: 34.8 (5.6) mL·kg–1·min–1; Malay: 33.0 (7.1) mL·kg–1·min–1; P = 0.208) and resting fat oxidation were similar among groups. Maximal fat oxidation during exercise was lower in Indian (3.81 (1.02) mg·kg–1·min–1, P = 0.004) and Malay (3.36 (0.9 5) mg·kg–1·min–1, P <  0.001) than Chinese (5.17 (1.23) mg·kg–1·min–1) men. Fat oxidation during exercise may contribute toward obesity risk in Asian populations. ClinicalTrials.gov Identifier: NCT05337111.
