George Abraham outlines the scientific principles of sports training as a systematic and progressive approach to enhancing athletic performance. He emphasizes the importance of principles such as individuality, which recognizes that each athlete responds differently to training; specificity, where training is tailored to the specific demands of a sport; and progressive overload, which involves gradually increasing the intensity of training to stimulate improvement. He also stresses reversibility, noting that gains are lost when training stops, and variation, which prevents plateaus and over training by altering exercises and routines. Abraham integrates these principles into a structured plan that balances training, recovery, and nutrition, aiming for peak performance through scientifically grounded methods.
