Abstract or Summary
  • Throughout the various levels of baseball competition, pitchers often suffer season-ending or career-ending injuries. Significant improvements have been made in the treatment and rehabilitation of these injuries, with a lesser amount of attention given to injury prevention. The purpose of this study was to determine the effectiveness of an inseason shoulder and scapular muscle strengthening program in the maintenance of the throwing velocity among high school baseball pitchers. Twenty-four apparently healthy high school baseball pitchers at four schools volunteered to participate in this study; each school was randomly assigned to either the treatment group or the control group. The treatment group pitchers (n = 12) engaged in a progressive resistance exercise (PRE) strengthening program using TheraBand® surgical tubing for six weeks, while the control group pitchers (n = 12) did no additional strengthening or stretching activities beyond their normal baseball training. Each subject's pitching velocity was measured using a JUGS® radar gun at the beginning of and following the six-week study period. Pretest and posttest concentric and eccentric muscular strength and power at 60 and 240 deg/sec were measured for the internal and external rotators of the shoulder using a KinCom 500H isokinetic dynamometer. Results of one-way ANOVAs indicated no significant differences between the groups on any of the experimental parameters at the beginning of the study (p > 0.05). Over the course of the baseball season, pitchers in the treatment group increased their throwing velocity an average of 6.2 mph compared to an average increase of 1.5 mph in the control group (p < 0.001). Group x Time interaction effects (p < 0.03) for 7 of 8 isokinetic peak torque measures indicated significant improvements in shoulder strength in the treatment group at the posttest evaluation. No time-loss shoulder or elbow injuries occurred in the treatment group during the six-week PRE program. Our results suggest that participation in an in-season PRE program of surgical tubing exercises for the shoulder was safe and successful, not only in maintaining, but significantly improving pitching velocity and the strength of the shoulder internal and external rotators among high school baseball pitchers. Our findings support the use of this low cost surgical tubing PRE program as a means to improve the throwing velocity of high school baseball pitchers.
