This study delves into the realm of sports psychology, aiming to investigate the intricate relationship between family dynamics and athlete nutrition within the context of the Saudi youth national team. Employing a descriptive research approach, a comprehensive questionnaire was administered, comprising three core dimensions: dietary intake assessment, the psychological impact of family dynamics, and individual beliefs regarding their influence on athlete nutrition. The questionnaire encompassed 28 statements and was administered to a sample of 90 players selected from the Saudi youth national team. From a sports psychology perspective, the study uncovers valuable insights. Firstly, it highlights the moderate impact of family dynamics as a social system on the dietary habits of Saudi youth national team players. It is evident that designated mealtimes serve as a crucial social gathering, wherein the family underscores the significance of adequate water consumption and the selection of nutritious foods. Remarkably, this study discerns no statistically significant differences at the 0.05 level concerning the relationship between family dynamics and sports nutrition, even when considering variables such as age and economic status among the Saudi youth national team players. In light of these sports psychology-oriented findings, it is recommended that future research endeavors within this domain explore the psychological aspects of how families support and influence athletes in maintaining their health, fitness, and physique through specific dietary regimens. This may include examining the familial dynamics and their psychological impact on athletes’ adherence to nutritional guidelines. Moreover, it is imperative to consider the role of familial support in mitigating psychological stressors related to nutrition and its impact on athletic performance. The integration of sports psychology principles into nutritional counseling and education for athletes and their families could prove highly beneficial. By enhancing understanding and communication within the family unit, athletes may better navigate the challenges of adhering to optimal nutrition strategies. Consequently, this approach has the potential to bolster not only athletic performance but also the overall psychological well- being of athletes, ensuring they are better equipped to handle the pressures of competitive sports.
