Abstract

Background and Aim: The aim of this study was to compare the two methods of reduce exercise volume after four weeks of glycogen depletion training on cortisol stress factor and CRP in male healthy Inactive.

Materials and Methods: 30 healthy inactive male undergraduate students from Qom University were purposefully selected and randomly assigned to three groups: 50% reduction in exercise volume, 75% reduction in exercise volume, and control. After four weeks of glycogen depletion training, including running back and forth for 2.5 hours, two sessions per week, one week of training adjustment was performed. Blood sample was taken in three stages, before starting the exercises, before and after adjusting the exercises. To investigate intra-group difference, repeated measurements test was used, and to investigate inter-group differences, numerical difference of pre-test-post-test and post-test-follow-up values and MANOVA statistical method were used at the significance level (α=0.05).

Results: The results of MANOVA between groups did not show significant differences in the two stages for the amounts of cortisol and C-reactive protein. But within subjects results were significant in 50% and 75% of cortisol at three time stages (P=0.02, P=0.03). Bonferroni post hoc test results showed a significant difference only between pre-test and follow-up in both groups (P=0.01, P=0.02).

Conclusion: In conclusion, seems that one week of reduce exercise volume after four weeks of glycogen depletion training cannot affect the levels of cortisol and CRP in male healthy Inactive.
