Abstrakt:	Background: Coaches usually reduce the training load (tapering) before competition to improve performance; however, in paralympic athletes this strategy had not yet been tested and we did not know which variables are associated with improved performance. Therefore, the objective was to compare the sleep, mood, sports performance, and reaction time (RT) of paralympic swimmers (PS) during tapering and to investigate whether there is a relationship between the variables during this training phase. Methods: Eight PS were monitored for 17 days before the main competition, with an actigraphy to record sleep in 16 days. Evaluations were performed on Mondays (Evaluation 1 = E1) and Fridays (E2) during the first and second weeks (E3 and E4), and on Tuesday (E5) of the third week, the day traveling to the competition. Brunel Mood Scale, RT (Psychomotor Vigilance Test), and sports performance (50 m in the pool) were assessed before training on each assessment day. Internal training load (ITL) was evaluated using ratings of perceived exertion. Results: ITL decreased gradually between assessments. Performance and RT were better on E5 than on E1. Fatigue was higher on E1 and E2 than on E4 and E5. Sleep parameters (total sleep time [TST], awakenings after sleep onset, and sleep efficiency) improved in the second week compared with the first week. Furthermore, TST from the previous night was correlated with RT, and RT and fatigue correlated with sports performance. Conclusions: The increase in TST and the reduction in fatigue just before competition achieved by tapering correlated with the improvement in RT and sports performance. In addition, the tapering improved sports performance, RT, sleep parameters, and decreased fatigue.
