Valoración del esfuerzo realizado en distintos tipos de ejercicios mediante la medición del estrés oxidativo y el perfil esteroideo urinario

Abstract

In this work, we have developed a stress model which could determine cellular damage and hormonal changes due to different kinds of physical activity, in untrained and in trained men. Results obtained suggest how high intensity activities generate an imbalance between free radical production and human body antioxidant response, in addition to changes in hormonal levels. Steady state aerobic activities, in spite of increasing reactive oxygen species (ROS), they provoke an antioxidant response which is able to offset ROS without any oxidative cellular damage. In relation to hormonal levels, there is a balance between catabolic/anabolic hormones, so physical stress is lower.
