The physiology and performance capabilities of older people are generally different than that of younger people. Regular physical exercise activity produces physiologic improvements regardless of age.
Exercise enables one to move faster and any age group.
This decline in aerobic capacity is largely due to decrements in physiologic function related to oxygen transport. Decrease in heart rate result in decreases in cardiac output and reduction of peripheral flow capacity. At 55 years old, active men maintained the same value for bold pressure, body weight and VO2 max as 45 year old sedentary men. To establish from ECG observations a diagnosis of any heart disease. To reproduce or assess exercise-related chest symptoms.
