Introduction: In accordance with traditional approaches to sport and competition, a warm-up period preceding higher intensity exercise is normally prescribed in hopes of positively influencing athlete health and performance. Purpose: The purpose of this study was to compare the effects of three different warm-up protocols on upper body power, lower body power, and agility. Methods: Thirty-three male and female fourth- and fifth-grade students (mean age 10.06 ± 0.49 years) performed the warm-ups, which included jogging only, jogging and static stretching, and jogging and dynamic stretching. Fitness tests administered include shuttle run (agility), vertical jump (lower body power), and seated medicine ball throw (upper body power). Interactions between day of testing, gender, and testing group (type of warm-up protocol implemented) compared with test results were analyzed utilizing analysis of variance (ANOVA). Results: Results of this study indicated no statistically significant relationships between warm-up protocol performed and shuttle run performance (p=.968), vertical jump performance (p=.901), and seated medicine ball throw (p=.554). These results indicate that a dynamic warm-up protocol may be just as effective as a 3-minute jog or a static warm-up protocol in preparing elementary school students for fitness testing. Conclusion: This suggests that incorporating dynamic movements into a warm-up curriculum may not elicit better results in agility or power-producing activities.
