With Spring training just around the corner, baseball and softball players looking to hit the ball harder might want to try out this high-intensity isometric potentiation technique examined in a study published in the Journal of Strength and Conditioning Research.
Scientists measured bat velocity just before striking the ball using motion analysis software. Twenty-eight experienced female softball players took swings 1, 2, 4, 6, 8, 10 and 12 minutes after warming up with 3 sets of 5-second maximum voluntary contractions with the bat immobilized early in the swing phase.
Maximum horizontal bat velocity was an average of 2.84 miles per hour faster 6 minutes after the isometric warm up. That’s an increase of 4.95% in swing speed.
