Of the 19 warm-up articles, 69% showed an improvement in sprint performance, 87.5% showed an improvement in jump performance, and 83% showed an improvement in agility performance. This suggests that a properly structured warm-up strategy can increase athlete performance in many different sports.
However, comparing results between studies is difficult due to different control groups and different warm-up protocols. Therefore, to define a properly structured warm-up strategy, it is important to know which variables are critical for optimising subsequent explosive performance.
Research tends to recommend a short, active warm-up that progresses in intensity until maximal effort close to the end of the warm-up. Shortly afterward, passive strategies should be implemented before the game and the re-warm-up should include short sprints and jumps before entering the game.
