Acute downhill running does not induce fat oxidation

Abstract

Objectives

Eccentric exercise has been suggested for its potential to increase several health outcomes, including exercise-induced fat oxidation. Comparison of exercise intensity rather than exercise workload is required.

Methods

Thirteen moderately active young men (mean age, 24.6 ± 5.6 years; body mass index, 23.76 ± 3.24 kg/m²; maximal oxygen consumption (VO_2max), 49.00 ± 3.19 ml/kg/min) performed two counterbalanced running sessions for 40 min at 60% VO_2max, either running flat (Con-Exe) or running downhill at a gradient of − 12% (Ecc-Exe). The volumes of oxygen and carbon dioxide (VO₂ and VCO₂) were collected during exercise sessions, and fat oxidation was calculated.

Results

There was no significant interaction between exercise condition and exercise duration (p > 0.05), and individual variations in fat oxidation during Con-Exe and Ecc-Exe were large and inconsistent.

Conclusion

Downhill running at 60% VO_2max and inclination of − 12% does not induce fat oxidation.
