Sobre a relação entre carga interna de treinamento e desempenho cognitivo, físico e técnico no futsal em atletas

Abstract

The precise control of internal training loads considering exercise stimuli and recovey is a challenge in sports. The manipulation of external load variables and the understanding of internal load variables affecting performance seem to be decisive for the success of sports training. The rate of perceived exertion is the most common tool for estimating internal load. It is easy to implement daily, low cost, and validated by Borg scale. The internal load is also related to psychobiological and neuromuscular aspects of exercise, as well the particularities of different sport disciplines. In this thesis, our goal was to better understand the relations between training load and cognitive, physical, and technical performance in futsal athletes during a competitive season. We conducted three studies aiming: 1) determine which physical/cognitive aspects determine the perception of internal load in highperformance futsal athletes, 2) investigate whether internal load relates with technical performance during official matches, and 3) determine the impact of the of internal load’s perception on the capacity to produce force, acceleration and tasks to change direction. Our main findings were that internal load is influenced differently by cognitive and neuromuscular factors at different stages of the season, the internal load experienced by athletes in the week before seems to slightly influence the technical performance in an official match, and the capacity to produce force and change of direction are negatively affected by the internal load experienced. Our results have potential for application in the field of futsal, especially considering the inclusion of physiological testing combined with biomechanics and cognitive tests in the routine of athletes' assessment. A better understanding of relationship between training load and cognitive, physical, and technical performance in futsal can help to 9 improve performance monitoring and planning of training sessions over a competitive season.
