Stretching is a common activity of professional athletes, elderly people, patients in rehablitation and recreational athletes that follow a training plan. The positive effects of stretching are known, it’s only a question of choosing the best stretching type for specific goals or outcomes. There are three basic forms of stretching: static stretching, dynamic stretching and PNF (proprioceptive neuromuscular facilitation) stretching. Static stretching involves the elongation of the muscles by holding in a slightly uncomfortable position, usually, 10 to 30 seconds. Dynamic stretching uses the swing of the extremity to elongate the muscles, but the last part of the movement is not holding. PNF stretching is typically used by activation of the agonist for the purpose of stretching the antagonist followed by an isometric contraction of the muscle that is to be stretched. Different sports require varying degrees of elasticity. In this paper, research on the effects of static and dynamic stretching on athletes in jumping and sprinting disciplines has been utilized from the PubMed database and Google Scholar. The objectives of the database search are to study the importance of stretching before a training session or a competition in jumping and sprintering disciplines. Warm-up exercises are meant to improve flexibility, encourage the musculoskeletal system to increase body temperature, warm up the muscles, tendons and connective tissue and prepare them to perform. Warm up should also stimulate the vascular system, improve coordination and allow for a more free and easier movement due to the leniency of the locomotion system. In addition, the heart rate and breathing rate increases. This results in increased circulation, which enables for greater and faster supply of oxygen and nutrients towards the muscles and causes improvement in athletic activities.
