Sex differences in the effects of 12 weeks sprint interval training on body fat mass and the rates of fatty acid oxidation and VO2max during exercise.

04 Mar 2016Bagley L, Slevin M, Bradburn S, Liu D, Murgatroyd C, Morrissey G, Carroll M, Piasecki M, Gilmore WS, McPhee JS.

Findings show lower body fat %, and higher rates of fatty acid oxidation and VO2max after 12 weeks of high intensity interval training for just 4 min per week. Notably, women improved VO2max more than men, while men lost more fat than women.
