This study was conducted to systematically compile and sythesize the studies about taper training in literature and in the most current form, to reveal the physiological changes caused by taper trainings. Qualitative research methods were used for in-depth study and interpretation of the studies on taper applications published between 1985-2020. Document analysis was used as data collection method and the obtained data were analyzed by content analysis method. Taper training is a complex training method that facilitates the systematic reduction of the training load and the attainment of the physiological harmony. Before the major competitions the reductions in load, density, volume or frequency of the training in order to achieve optimal performance are made which is called the taper. The aim of taper training is to reduce fatigue and increase physiological adaptation and performance in athletes through intensive training. Since each sport branch has different physiological demands, taper trainings are applied differently in individual and team sports. The effects of these practices may vary in athletes in different branches. In the literature studies, some increases were found in the blood volume and red blood cells values, muscular glycogen deposits, some enzymes, blood lactate and VO2 max. values and the movement economies of athletes. However, in some studies, some decreases were found in the levels of the respiratory threshold, creatine kinase in the blood and the values of the submaximal ventilation, the diastolic and systolic blood pressures of the athletes.
