    Abstract

    Purpose: Previously it has been reported that reduced-exertion high-intensity intervaltraining (REHIT; total training time of 3x10 min per week) improves aerobic capacity(V̇O2max) in both sedentary men and women, but improves insulin sensitivity in men only.The aim of the present study was to determine whether there is a true sex difference inresponse to REHIT, or that these findings can be explained by the large interindividualvariability in response inherent to all exercise training.Methods: Thirty-five sedentary participants (18 women; mean±SD age for men and womenrespectively: 33±9 and 36±9 y, BMI: 25.1±2.1 and 24.1±3.5 kg�m-2, V̇O2max: 38.6±8.3 and 31.6±4.6 ml�kg-1�min-1) completed a 6-week REHIT programme consisting of eighteen 10-min unloaded cycling sessions with one (first session) or two (all other sessions) 'all-out' 10-20-s sprints against a resistance of 5% of body mass. V̇O2max and oral glucose tolerancetest (OGTT)-derived insulin sensitivity were determined before and after training.Results: REHIT was associated with an increase in V̇O2max (2.54±0.65 vs. 2.78±0.68L�min-1, main effect of time: p
