Performance and energy systems contributions during upper-body sprint interval exercise

The main purpose of this study was to investigate the performance and energy systems contribution during four upper-body Wingate tests in-terspersed by 3-min intervals. Fourteen well-trained male adult Judo athletes voluntarily took part in the present study. These athletes were from state to national level, were in their competitive period, but not en-gaged in any weight loss procedure. Energy systems contributions were estimated using oxygen uptake and blood lactate measurements. The main results indicated that there was higher glycolytic contribution compared to oxidative (P
