Changes in athletic performance specific to baseball ability will be assessed before, during, and after four months of chiropractic care. The specific aim of this study is to measure the effects of chiropractic care on the athletic performance of members of a NCAA Division II collegiate baseball program. Each athlete's performance will be assessed using a series of quantitative tests specific to baseball, i.e., hand eye coordination, bat speed, running speed, visual acuity, and throwing velocity. The athlete's general health will be assessed by the SF-36 survey, and the heart rate variability measurement (HRV). The players will be randomly divided into an experimental and a control group. Only players in the experimental group will receive chiropractic adjustments, while the control group will be given sham adjustments. All players will be checked and monitored weekly for chiropractic care and monthly for athletic performance. After completion of the study, those subjects not receiving chiropractic care will be offered actual care for four months. A comparison of the individuals receiving chiropractic care and those receiving no care will be performed to determine if chiropractic care had any measurable effect on the tests utilized to measure athletic performance specific to baseball.
If chiropractic care is effective in improving athletic performance in baseball players, it will support the hypothesis that healthy individuals and athletes may benefit from such care. This may also warrant further study on chiropractic care for athletes involved in other sports.
