J Strength Cond Res 32(1): 359-364, 2017-The purpose of the study was to investigate whether performing 3 consecutive countermovement jumps (CMJs) just before an attempt enhances performance in track and field throwers during competition. Twelve shot putters, 8 hammer throwers, 9 discus throwers, and 3 javelin throwers of both sexes participated in the study. They performed 3 maximal CMJs 85 {\textpm} 12 seconds before the second, fourth, and sixth attempt during 3 different official competitions of national level. Maximal strength (1 repetition maximum [1RM]) in squat and bench press was measured 1 week after the competition. Mean throwing performance was significantly higher after the CMJs intervention (2.66 {\textpm} 4.3\%, range of increase 0.02-18.98\%, p = 0.0001). Similarly, maximum throwing performance was significantly higher after the CMJs (2.76 {\textpm} 3.29\%, range of increase 0.09-13.93\%, p = 0.0009). All but 2 athletes increased their best performance after the CMJs. The percentage increase in performance was similar between sexes (male athletes 2.56 {\textpm} 3.01\%; female athletes 3.06 {\textpm} 3.76\%, p = 0.677), but it was higher for the "lighter throws" (discus and javelin throw: 4.66 {\textpm} 4.11\%) compared with the "heavier throws" (shot and hammer throw: 1.62 {\textpm} 2.04\%, p = 0.008). The percentage increase in performance was not significantly correlated with 1RM squat or bench press, anthropometric characteristics, and personal best performance. These results suggest that performing 3 CMJs approximately 1 minute before an attempt may increase track and field throwing performance during competition.},
