Explosive power is defined as an ability of short-term maximum muscular force to accelerate the movement of a body or it`s parts. In most disciplines of Athletics, the basic criterion of success is the development of the greatest possible reactive force in the shortest possible time of contact with the ground. The aim of this review is to determine the differences in the explosive strength of the lower extremities of athletes who train Athletics and athletes from other sports. For analyzing the adequate literature the following electronic databases were searched for papers published between 2002 and 2020: PubMed, MEDLINE, Google Scholar, ScienceDirect, and Embase. The following terms were combined to design the search strategy: explosive strength of lower extremities, athletics, countermovement jump, tensiometer platform and vertical jump. Included studies were uncontrolled randomized and non-randomized transversal and longitudinal studies that examined the explosive power of the lower extremities in athletes (Athletics) and other athletes using a variety of tests. The included respondents are top athletes of both gender, aged 15 to 35. Of the 578 studies, through elimination and selection based on inclusion and exclusion criteria, 20 studies were selected. Athletes generate greater strength and power than all other subjects of other analyzed sports, for the values of drop jump from the height (60 cm, p=.01). Athletes need less time at the moment of impulse than other groups of athletes, as well as less time for amortisation. Drop jump (60 cm) parameters show that there is a negative correlation for force, reaction time, strength and jump height (-0.4 up to -0.81, p=.001). In sports that are explosively demanding, with the help of various tests, it has been established that athletes have the best values of contact parameters in relation to other sports.
