Strength professionals commonly incorporate field-based exercises designed to translate to a particular sport movement. Swinging a bat involves a complex, sequential movement pattern through multiple planes of movement. PURPOSE: The purpose of this study was to examine the relationship between lateral rotational jumps on bat velocity and peak hand speed in collegiate baseball players. METHODS: Thirteen college baseball players (age: 20.15 ± 1.77, height: 180.25 ± 6.74 cm, weight: 86.66 ± 10.77 kg) completed a baseline testing session of lateral rotational broad jumps. Athletes completed a dynamic warm-up followed by 2 attempts of lateral rotational broad jumps for lead and trail leg based on their respective batting stance. On a separate day, athletes took 5 swings with their game bat (33in/30 oz, 34in/31oz) off a tee with 20 seconds in between each swing to mimic the time between pitches. Each participant was instructed to step up into the batter’s box as they would in a practice/game situation while the investigator placed the tee in the middle of each of their respective strike zone based on batting stance. Each participant was instructed to hit a line drive over the shortstop or second baseman’s head depending on which side the athlete hit from. A blast motion sensor was used to collect swing metrics of each swing trial. The average of the 3 best swing attempts were taken based on bat velocity. Researchers collected and analyzed possible relationships between lateral rotational jumps of the lead and trail leg on swing outcomes of interest. A series of Pearson’s correlation coefficients were used at an alpha level of p&It.05 to determine if a significant relationship was found. RESULTS: A negative association was found in lateral rotational jumps of the trail leg on bat velocity of -.538 with a p&It.05. No other significant relationships were observed in lateral rotational jumps on the remaining swing outcomes. CONCLUSION: Strength professionals can use this data to incorporate multi-planar exercises in their programs to help aid in bat velocity.
