Abstract
The muscle's physical characteristics enable it to absorb energy. An injury occurs when the energy generated exceeds this intrinsic capacity. Muscle injuries can be classified into four main groups: 1. Delayed-onset muscle soreness (DOMS) 2. Strains: - First degree: local fibril and filament damage with no solution of continuity - Second degree: interruption of a certain number of muscles fibres without involvement of a grossly recognisable portion of the belly - Third degree: rupture of a large portion of the belly with clinically evident solution of continuity 3. Contusions: - Intermuscular haematoma - Intramuscular haematoma 4. Avulsions: - Osseous - Apophyseal - Muscular In the case of strains, the muscle-tendon junction is particularly at risk due to its lesser extensibility and the sudden reduction of local circulation in the tendon compared with the muscle and the bi-articular muscles, especially the hamstring with their greater number of type 2, fast-contraction fibres [1-3]. The clinical and functional picture of strains is worse the greater the tissue damage (Table 1).
