Abstract:
Throwing velocity is undoubtedly considered as one of the crucial factors that affects output of a
baseball game .To improve throwing velocity, numerous training methods and approaches are being
used .Therefore, the purpose of this study was to find the effect of the resistance band and weight
training on throwing velocity of age (27±3),( mean ± SD )club level baseball players in Sri Lanka .
Forty baseball players were recruited for the 8-week training program based on the inclusion criteria
and availability of players .Initially, athletes were assigned into 3 groups :a control group (n=10), a
weight training group (n=15), and a resistance band training group (n=15 .)The weight training group
performed 6 upper body exercises by using barbells and dumbbells while the resistance band training
group engaged in 6 upper body exercises with blue and red coloured bands. Moreover, the control
group was only allowed to perform their daily routine baseball practices which were 3 days per week
and 3 hours per day. Throwing velocity was measured by using a radar gun, and upper body strength
was measured using the one-repetition maximum (1RM )bench press test to determine the relationship
between strength and throwing velocity .Both test results were evaluated by using pre-test and posttests’ descriptive and inferential statistics .The weight training group and the resistance band group
showed significant differences in 1RM bench press and the radar gun tests while the control group
showed only a significant difference in the strength test .In addition, the control group revealed no
significant difference in throwing velocity .Furthermore, the weight training group showed the greatest
improvement in throwing velocity and 1RM bench press tests, and then the resistance band group
followed the same .In conclusion, Strength training and resistance band training can be utilized to
develop strength in the upper body and it may help to develop throwing velocity in other throwing
sports, such as cricket, throw ball and so on.
