Researchers from McMaster University in Ontario, Canada,compared the metabolic and performance adaptation of high intensity sprint interval training with that of traditional interval training. Either a high volume endurance training
group or a low volume sprint interval training group. Both groups performed six training session over two weeks of training. The endurance training group exercised at 65% of maximal aerobic power (~175 w) for between 90-120 min for a total of 6500 kj of work. Th e sprint interval group performed four to six sets of 30 second sprint intervals with a four minute recovery between each set for a total of 630 kj of work.
There were no differences in the physiological adaptations between the two groups. Th e authors concluded that sprint interval training was a very time efficient method for improving endurance which has the potential to induce rapid performance and muscle adaptations which are comparable to endurance training.
