Abstract
Heart rate variability (HRV) is one of the most important indicators for heart and overall health. In present study, the effect of long-term head tilt excises on HRV is experimented. The results demonstrated that heart rate variability can be enhanced through long-term head tilt excises. In addition, HRV decreases as the increase of pulse wave velocity. Pulse pressure increases as the increase of pulse wave velocity. Diastolic pressure decreases as the increase of pulse wave velocity. The physiological mechanism by which long-term head tilt exercises enhance HRV is that the exercises reduce sympathetic nervous activity and increase parasympathetic nervous activity by squeezing the back of the neck. Long-term head tilt exercises can help maintain sympathetic activity at a lower level while keeping parasympathetic activity at a higher level, thereby enhancing HRV.

Keywords head tilt excises;heart rate variability (HRV);pulse wave velocity (PWV);pulse pressure (PP).
