Objective: The objective of the study was to find the effectiveness of core stabilization exercises over a trunk extensor endurance training protocol (TEEP) in improving trunk extensor endurance. Methods: 30 physiotherapy students in the age group of 18-23 from KJPCP were conveniently selected and randomly allocated to a control and experimental group having 15 subjects each. Experimental group was given a trunk extensor endurance protocol along with a core stabilization program and control group was given only TEEP. Both exercises were given for half an hour each, 6 days a week, for 6 weeks. Results: It was found that core stabilization exercises along with TEEP is not significantly different from trunk extensor endurance training protocol alone in improving endurance of trunk extensors. Conclusions: TEEP protocol alone is effective in improving trunk extensor muscle endurance and its combination with core stabilization exercises will not produce any significant improvements over use of TEEP alone.
