Age features of regulation of heart rate during local muscle work

The reaction of the heart to the local muscles, produced up to fatigue in adult subjects 4 age groups with cardiointervalography was investigated. The age differences in adaptive response of the heart to the local load. The most favorable character of adaptive reactions observed in patients adulthood. The young men and the elderly adaptive response is often characterized by high degree central regulatory mechanisms. The elderly compensatory mechanisms at work appear to strengthen the activities of both the sympathetic and parasympathetic effects on the heart.
