Investaging the effect of plyometric, strength and combined exercises on the strength, agility and speed of athletes; A qualitative study

Sports performance requires optimal conditions of various variables that an athlete is learning throughout his sports career. Among the very important variables related to sports performance, we can mention strength, agility and speed, which mainly play a decisive role in anaerobic disciplines, and their strengthening and improvement is very important in the athlete's conclusion. The findings indicate different effects of different types of exercises on anaerobic variables including power and speed. So, the effects of these exercises depend on the intensity, duration and type of exercise. The purpose of this study is to review the effect of plyometric, strength and combined exercises on leg power, agility and speed of athletes based on the studies conducted in this field.
