AB  - Bench press is a popular training-exercise in throw related sports such as 
      javelin, baseball and handball. Athletes in these sports often use bouncing 
      (i.e., letting the barbell collide with the chest) to create an increased 
      momentum to accelerate the barbell upwards before completing the movement by 
      throwing the barbell. Importantly, the effects of the bouncing technique in bench 
      press have not been examined. Therefore, the aim of this study was to compare the 
      effects of bench press throw with (BPTbounce) or without bounce (BPT) on throwing 
      velocity (penalty and 3-step), 1-repetition maximum (1-RM) and average power 
      output (20-60kg) in bench press among handball players. Sixteen male amateur 
      handball players (7.1+/-1.9 years of handball experience) were randomly allocated 
      to an eight-week supplementary power training program (2 x week-1) with either 
      the BPT or BPTbounce. Except for the bounce technique, the training programs were 
      identical and consisted of 3 sets with 3-5 repetitions at 40-60% of 1-RM with 
      maximal effort in free-weight barbell bench press throw. The results revealed no 
      significant differences between the groups in any of the tests (p = 0.109-0.957). 
      However, both groups improved penalty throw (BPT; 4.6%, p<0.001, ES = 0.57; 
      BPTbounce; 5.1%, p = 0.008, ES = 0.91) and 1-RM (BPT; 9.7%, p<0.001, ES = 0.49; 
      BPTbounce; 8.7%, p = 0.018, ES = 0.60), but only the BPT improved the 3-step 
      throw (BPT; 2.9%, p = 0.060, ES = 0.38; BPTbounce; 2.3%, p = 0.216, ES = 0.40). 
      The BPT improved power output only at 20kg and 30kg loads (9.1% and 12.7%; p = 
      0.018-0.048, ES = 0.43-0.51) whereas BPTbounce demonstrated no significant 
      differences across the loads (p = 0.252-0.806). In conclusion, the bounce 
      technique demonstrated similar effects on throwing velocity, muscle strength and 
      muscle power output as conventional bench press throw without the bounce 
      technique.
