Efeito do treinamento concorrente na economia da corrida

Abstract

INTRODUCTION. Concurrent training is characterized by the simultaneous practice of strength training with some form of aerobic training. On the other hand, strength training is related through neuromuscular adaptations, such as musculotendinous rigidity, recruitment and synchronization of motor units, intra- and inter-muscular coordination and neural inhibition, has the potential to improve performance in endurance athletes and power factors Muscle-specific aerobic training. In this way, we consider a great running economy an athlete with increased Vo2max and who can have a lower energy expenditure at the lactate threshold, so we can see how aerobic training can act directly to improve the running economy, becoming an important Tool for performance. Many runners have the perception that aerobic endurance training only improves with much resistance training. Historically, runners hesitated to perform strength training because of concerns about possible side effects such as hypertrophy in capillary density and mitochondrial function. In order to gain a better understanding of the influence on aerobic training and thus contribute to the daily life of running athletes, the present literature review aims to verify the effect of concurrent training on the running economy. METHODS. Six articles were selected that met the following criteria: 1) experimental articles that have been published since 2010; 2) articles whose sample consisted of professional or recreational street runners; 3) presence of concurrent training (strength and aerobic) in the experimental design; 4) economy of movement of the race as a variable presented in the results of the study. RESULT. Of the six studies analyzed, five showed improvement in the running economy. The protocols analyzed showed that the studies that stimulated explosive strength training had an influence on the racing economy. CONCLUSION. The observed studies show that neuromuscular factors can directly interfere in the improvement of aerobic capacity when an acute analysis of the concurrent training is made. Strength training tends to induce muscle work efficiency and improve body stability, which allows for a greater volume of training and better impulse transmission. Strength training can positively influence many parameters that are supposed to correlate with running economy
