Abstract
The present study examined the effects of seven high intensity, intermittent training (HIIT) sessions on skeletal muscle fuel contents, mitochondrial enzyme activities, whole muscle fatty acid transport proteins, whole body VO2peak, and whole body metabolic, hormonal and cardiovascular responses to submaximal exercise. Eight females participated in the study (22.1 ± 0.2 yrs, 65.0 ± 0.8 kg, VO2peak: 2.36 ± 0.17 lmin-1). Subjects performed a VO2peak test and a 60 min cycling trial at ~60% VO2peak prior to and following training. HIIT consisted of 7 sessions in total performed every other day over a two week period. Each HIIT session consisted of ten 4 min bouts at ~90% VO2peak with 2 min of rest between bouts. VO2peak increased (p
