Effects of Low Intensity Running on Physiological Responses in Subjects with Impaired Cardiovascular Function

Background: Investigation of physiological adaptations to physical exercise loading may provide important information concerning health and fitness in young subjects with impaired cardiovascular functions.

Aims: To develop an exercise program for a group with cardiovascular deficiencies based on physiological adaptations.

Method: Indicators of the circulatory, cardiovascular and respiratory responses to the execution of common physical exercise programs and a progressive low-intensity running program were investigated. Six series of trials were conducted.

Statistical analysis including factor analysis was employed.

Results: It was found that performing a special exercise program increased the functional capacity of the cardiovascular system, increased homeostatic (milieu interior) stability and functional capacities, as well as contributed to the physical development rate and the ability to increase the physical training load. The special exercise program enabled concomitant motor and physiological development.

Conclusion. The most important adaptive responses were related to cardiac function, acid-base balance and hemodynamic variables. These adaptations can be used as criteria for physical training program development. These variables can also be used as physiological criteria for physical exercise loading. The special exercise program enhanced concomitant motor and physiological development.
