Abstract
Background: This experiment has been designed for you to learn more about the way the cardiovascular system how it respond toward exercise. The prevalence of cardiovascular disease and its resultant debilitation of cardiac performance are expected to increase in the future generation. Eelier research on cardiovascular adaptations to endurance training has primarily focused on young generation. Recent work on the present study indicates that the basis of trained older male’s increased aerobic power is their superior ability to increase stroke volume during exercise, which, in turn, allows them to marked increase in cardiac output.

Aims and Objectives: The aim of the study was to assess the differences in cardiovascular responses to exercise in trained and untrained individuals.

Materials and Methods: In this, 100 subjects were included and divided into trained (50) and untrained (50) for a minimum of 1 year duration by the time of study and 50 untrained individuals acted as controls. Institution ethics committee permission obtained and the subjects performed four exercise sessions per week for a minimum of 1 year duration by the time of study; supervised by the personal trainers at gym center, according to instructions.

Results: The mean resting heart rate (HR) of strength trained was lesser when compared to mean resting HR of untrained.

Conclusion: Regular strength training exercise results in a decrease in weight, body fat, resistance of insulin, triglycerides, and an increase in excess good cholesterol levels. Regular strength training exercise if performed within normal limits decreases cardiovascular risk factors.
