Description: The purpose of this study was to describe the physiologic response to exercise of clients with mitral valve prolapse syndrome (MVPS). The conceptual framework used to guide this study was derived from the Neuman Health-Care Systems Model and was enhanced by appropriate physiologic principles.

The sample consisted of 72 females between the ages of 20 and 40 who had had a metabolic graded exercise test (MGXT) at a local center. The records of clients who met the criteria for inclusion were reviewed to obtain the necessary data. The rights of the subjects were protected by adherence to Institutional Review Board guidelines.

Descriptive statistics were used to describe the sample. Analysis of the demographic data indicated a statistically significant difference between the groups with regard to weight and age (Neuman-Keuls p = $<$.05). The normals were heavier and older than the MVPS groups.

The one-way analysis of variance on repeated measure (resting to peak) for heart rate revealed a significant difference between the MVPS groups, but neither group was significantly different from the normal group. The F statistics for the repeated measure procedures on systolic blood pressure were not significant at the.05 level of significance and resulted in the acceptance of the null hypotheses. The one-way analysis of variance for peak oxygen consumption (VO$\sb2$), time to peak VO$\sb2$, MET level reached, and rate of perceived exertion resulted in the null hypotheses being retained. The F statistics indicated no significant difference at the.05 level of significance among the three groups.

As a result of the findings, it was concluded that at least for this study, there was not a significant difference for response to exercise among the three groups. The conclusion leaves open the question whether there is a need to teach clients with MVPS differently with regard to exercise. Additional studies are needed to better understand exercise in clients with MVPS.
