This study will employ a randomised, double-blind, placebo-controlled, independent groups experimental design. Submaximal, maximal and 5 km time trial running performance will be assessed before and after supplementation with haskap berry or a placebo.
Participants will consume haskap berry powder or an isocaloric placebo for 7 days. They will be required to run on a treadmill before and after supplementation to asses the influence on the intervention on aerobic performance parameters. Other performance parameters such as blood lactate, heart rate, ratings of perceived exertion and respiratory variables will also be monitored throughout the various elements of the exercise trials.
