Sports injuries should be considered not only as physical problems but also as multidimensional phenomena affecting the athlete’s psychological, social, and professional well-being. This book presents a holistic perspective on sports injuries, integrating biomechanical and psychosocial dimensions. The first chapter examines the factors influencing anterior cruciate ligament (ACL) injuries, while the second focuses on preventive training methods. The third chapter discusses the psychological and psychosocial effects of injuries, and the fourth explores the delicate boundary between exercise and sport with reference to the realities of sudden cardiac death. The final chapter addresses rehabilitation and the process of returning to sport. Designed as both an academic and practical resource, this book aims to guide sport scientists, physiotherapists, coaches, and health professionals in understanding and managing sports injuries comprehensively.
