The hamstring muscles are particularly susceptible to injuries during sports. Current statistics, especially from soccer and American football, show that despite active prevention in training and game preparation, the injury rate of the so-called hamstrings has remained constant over the last ten years. The functional effectiveness of this muscle group is often underestimated, but the high susceptibility to injury can be proactively addressed through differentiated training. In "Strong and Healthy Hamstrings," the authors take a holistic view of the hamstring muscles, clearly explain the biomechanics, and present injury mechanisms based on the latest scientific findings. Effective prevention strategies and training methods are demonstrated, including flexibility and strength training as well as plyometric training.
