Introduction: Football and handball are among the most popular sports today. A large population of people participates in these sports both professionally and at an amateur level. The dynamics, contact play, and the excitement of scoring are some of the aspects that attract a large number of people, including children, who start engaging in sports from a young age. Nowadays, the pace of the game has changed; everything has accelerated, and players are expected to perform more, stronger, and better, which ultimately leads to a higher risk of injury. Some reasons for this include contact play, inadequate prevention, and ultimately, overtraining of players. Aim: This paper delves deeper into the prevalence of injuries among amateur football and handball players, the role of physiotherapists, and the importance of injury prevention. Through an analysis of the frequency of upper and lower limb injuries and the impact of rest between training sessions on musculoskeletal injuries, the research highlights the need for tailored injury prevention strategies for these two sports. The importance of individualized injury prevention programs, tailored to the specific needs of each athlete, is emphasized. The key role of physiotherapists in implementing these strategies and supporting the health and performance of athletes is also highlighted. Participants and Methods: The study involved 72 male participants from football and handball clubs, both amateurs and professionals, who actively participated in training and competitions. Data was collected through an online questionnaire divided into three sections: sociodemographic questions, questions about injuries and training, and the presence of medical staff in the clubs. Results: The study included 72 participants from football and handball, with an average age of 25.2 years. The majority of participants (73.6%) engaged in sports at an amateur level, while 20.8% were professional athletes. Most participants were involved in handball (63.9%) and football (36.1%). The prevalence of injuries was high, with lower extremity injuries being the most common (63.9%). The most common injury treatment was physiotherapy (56.9%), while 16.7% did not seek any help. A statistically significant difference in injury incidence between amateur and professional athletes was not found, and longer rest periods did not significantly reduce injury incidence. Additionally, there is a strong need for physiotherapists in lower leagues, supported by 90.3% of participants. Conclusion: The research highlights the importance of individualized training programs that balance intensity, frequency, and specificity to optimize athletes' physical fitness. Moderate and targeted training yields better results than excessive or insufficient intensity. Recovery plays a crucial role, with physiotherapists supporting injury prevention, rehabilitation, and performance optimization. Integrating physiotherapy with training helps prevent injuries, correct imbalances, and enhance strength and flexibility. A holistic approach involving proper nutrition, rest, and injury prevention is essential for sustained athletic performance. Future research should focus on personalized protocols that maximize athletes' potential while minimizing injury risks.
