Batting is known to be one of the most complex motions in sports. Successful hitting may be influenced by many factors, one of which is response time (RT). Response time is known to be altered by various training techniques such as isokinetic and isometric weight training. Eighteen, right-handed female college softball players were measured for RT with three methods, experimental in design, using an Automatic Performance Analyzer.In addition, hitting performance was determined through film analysis of bat velocity while swinging at a ball delivered from a pitching machine. A Locam camera was used for the cinematography techniques.From this initial testing, three equivalent groups were formed. One group served as a control, while the other two groups performed two contrasting seven week isotonic training programs: 1) a rapid dynamic (RD) group performed many, quick light weight activities; while, 2) the slow exercises. The rapid dynamic group had their exercises triggered by an auditory stimulus. Following the seven week training program, RT and batting performance were again determined. Pre- and post-training response times were analyzed using an analysis of variance and covariance with p=0.05.The results of the RT post-test analysis indicated that response times were not significantly decreased for any of the tests. Film analysis was inadequate to make any conclusive judgments on bat velocity.The following conclusion is warranted from the results: isotonic weight training did not significantly decrease response time for either the slow dynamic or rapid dynamic group.
