Training vacation?: Caution, two weeks of interruption training cause physiological and psychobiological alterations!. Motri. [online]. 2016, vol.12, n.1, pp.106-114.

To investigate the impact of two weeks of detraining in aerobic capacity and the psychobiological responses of runners, 16 adult volunteers were recruited. After clinical assessment, the volunteers were submitted to body composition evaluate, blood collection, maximum cardiopulmonary exercise test and constant load test in ventilatory threshold intensity 1 (VT-1), and answered psychobiological questionnaires to evaluate anxiety, mood profile and exercise dependence. A week after these tests, the volunteers were submitted to a detraining period sustained by two weeks. At the end of this period, the volunteers answers the psychobiological battery again and the cardiopulmonary exercise test on VT-I intensity was repeated. Psychobiological tests were applied again after the completion of the exercise. The results revealed that the detraining period caused a decrease in oxygen consumption and ventilation at 9.1 and 8.6%, respectively, furthermore, the detraining increased negative mood symptoms as anxiety, stress, depression, anger-hostility and decreased vigor. After the exercise, a relief of negative mood symptoms and increased of vigor was observed. We conclude that the interruption of training for a short period of two weeks causes a decrease in aerobic capacity and promote psychobiological alterations.
