ABSTRACT Sports performance is influenced by the interaction of several physical variables. For this reason, most sports need both strength and endurance capacities to maximize overall performance. Therefore, a combination resistance aerobic training, usually called concurrent training (CT), has been used recently as way simultaneously improving performances according needs specific sport. This can be challenging influence adaptations, being problematic issue for coaches. The main objective...
