If someone has the feeling of tightness in the hamstrings there can be a variety of reasons for this. Probably the most common is there is something wrong in the back or pelvis (even if they feel no symptoms here). Also there could be some local problem in the hamstrings themselves such as a tear or scar tissue.
Hamstring strains occur more often in adolescents because bones and muscles do not grow at the same rate. During a growth spurt, a child's bones may grow faster than the muscles. The growing bone pulls the muscle tight. A sudden jump, stretch, or impact can tear the muscle away from its connection to the bone.uscle overload is the main cause of hamstring muscle strain. This can happen when the muscle is stretched beyond its capacity or challenged with a sudden load. Hamstring muscle strains often occur when the muscle lengthens as it contracts, or shortens.
