Abstract:

The study was to determine the effects of OMT on blood pressure and heart rate (HR) in softball players. Subjects received up to three treatments (T1, T2, T3). The treatment group showed a decrease in HR between the pre-treatment (pre-tx) and post-treatment (post-tx) values at T2 (p<.01) and T3 (p<.05), with the changes in HR for the treatment group being greater than the control group at T2 and T3 (p<.01). Pre-tx HR comparisons between groups demonstrated differences at T 2 and T3, with the treatment group being higher (p<.01 ). The pre-tx HR values of only those subjects receiving three treatments increased from T, through T3 (P<.05). The post-tx HR for the treatment group at T3 was lower than that of the control group (p<.01). The drop in this group increased with subsequent treatments (p<.05), suggesting the efficacy of OMT in reducing HR was not solely dependent upon elevated pre-tx HR values. These findings were validated statistically by using analysis of covariance with the appropriate equations and a multiple comparison procedure (P<0.5).
