Abstract
Purpose: To find out the acute effect of three different intensities of resistance exercise on serum cortisol level in elderly subjects. 45 men and women (22 men and 23 women) elderly subjects (age: 60 - 70 years old) from normal subjects (patients’ companions in Eldemerdash teaching hospital Ain Shams university), from January 2015 till June 2015. They were divided into three groups. group (A) was composed of 8 men and 7 women; they received one bout of low intensity resistive exercise. group (B) was composed of 6 men, and 9 women, they received one bout of moderate intensity resistive exercise. group (C) was composed of 8 men and 7 women, they received one bout of high intensity resistive exercise; duration of the treatment was 45 minutes, starting from 9:00am till 9:45 am. The subjects’ age, height, weight, and BMI were measured. Also, the serum cortisol level was measured just before the exercise session at 9:00 am and 5- minutes after the session. The results showed that in group (A): the pre cortisol value was 7.85 ± 3.92 and the post cortisol value was 5.70 ± 2.03. In group (B) the pre-cortisol value was 7.11 ± 2.85 and the post-cortisol value was 5.41 ± 1.49. In group (C) the pre-cortisol value was 6.77 ± 2.76 and the post cortisol value was 6.403 ± 2.572. There was a significant decrease (27.388%) in serum cortisol level after the low-intensity resisted exercise, and there was a significant decrease (23.909%) in serum cortisol level after the medium-intensity resistance exercise, and there was no significant change in the high intensity resistance exercise in the elderly subjects, and the low-intensity (30% of 1- RM) was more fruitful and beneficial in decreasing the stress response manifested by the serum cortisol level in elderly subjects. The low-intensity (30% of 1- RM) is more advantageous on serum cortisol level than both the medium-intensity 50% of 1- RM and high intensity 80% of 1- RM resistance exercise in elderly
