The effect of pre-exercise protein compositions on substrate metabolism during sub-maximal exercise and 4 km time-trial performance

This experiment investigated how consuming energy-matched (0.5 gr/kg body mass) whey protein, soy protein, maltodextrin, 1:1 maltodextrin:whey or a non-caloric placebo thirty minutes before exercise influences whole-body substrate metabolism and exercise performance (4-km cycling time trial).
