ABSTRACT
PURPOSE: This study aims to examine the physical activity and eating habits of elite athletes to identify changes in their weight and participation levels in competitions pre- and post-COVID-19, and to establish a database of the abovementioned factors for the post-COVID-19 period. METHODS: This study surveyed 913 elite adult athletes from 22 sports. They were divided into two groups: weight loss athletes' group (WLG) and non-weight loss athletes' group (NWLG). In addition to demographic factors, the questionnaire included questions about physical activity, sleep, and eating habits pre- and post-COVID-19 pandemic. The survey included 46 questions requiring short subjective answers. Statistical significance was set at p<0.05. RESULTS: In the post-COVID-19 pandemic period, physical activity and sitting decreased in athletes of both groups. The difference in the number of meals consumed by both groups varied, and the number of tournaments the athletes participated in decreased for all sports. The success or failure of weight loss is essential for maintaining athletes' performance and health. CONCLUSION: Coaches play an important role in investigating and managing the weight loss regimen of athletes during crisis situations like a pandemic. Additionally, athletes must find the best way to maintain their competencies to the standards set before COVID-19. Adhering to such a regimen will have the greatest impact on their tournament participation in the post-COVID-19 pandemic period.
