This paper focuses on the effects of plyometric trainings on upper extremity anaerobic power and shotspeed in 20 volunteer male handball players, who are in the men's handball team at Süleyman Demirel University. Players were randomly divided into two groups as handball training group (HTG) and plyometric training group (PTG). While HTG continued routine handball training, plyometric trainings were applied to PTG additionally for 8 weeks, 3 days a week, at least 30 minutes a day. The upper extremity anaerobic power and shotspeed tests were applied to the groups in 1st and 8th weeks of the period (Inbar et al., 1996). Data analysis was made by using comparison tests. The study reveals that plyometric trainings have positive effects on shotspeed in handball. Considering that plyometric training provides maximum contraction in the shortest time possible, it can be said that applying plyometric training in pre-season and in-season training programming may be more effective.
