Abstract
Introduction: The purpose of this study was to compare the strength and endurance of flexor and extensor of trunk muscles in individuals with and without core dysfunction.
Methodology: 47 female students in two groups, 32 people with core dysfunction (25.90 ± 2.68 years) and 15 people without core dysfunction (23.60 ± 3.22 years) participated. Individuals with core dysfunction were determined by tuck jump assessment. The strength of the flexor and extensor muscles of the trunk was measured by Nicholas dynamometer and the average of three measurements was recorded as strength. Endurance of trunk flexor muscles was measured by trunk flexion test at 60 degree and endurance of trunk extensor muscles was measured with Sorensen Test and the time was recorded as endurance with a chronometer.
Results: The results was showed that strength of trunk extensor muscles (P= 0.029), endurance of trunk extensor muscles (P = 0.023), and endurance of trunk flexor muscles (P = 0.003) There was a significant difference between the two groups with and without core dysfunction. However, the strength of trunk flexors muscles (p = 0.491) was not significantly different between two groups with and without core dysfunction. Independent t-test was used for comparison of difference among groups.
Discussion: According to the findings of this study, it seems that in individuals with neuromuscular core dysfunction, there is a higher fatigability (less endurance) in the trunk flexor and extensor muscles compared to those without core dysfunction. Also, increased pressure and activity in the trunk extensor muscles of individuals with core dysfunction leads to more fatigue and weakening of these muscles and, in fact, decreases their strength, but the strength of the trunk flexor muscles (such as the rectus abdominus) because these muscles has not significant role in stabilizing and controlling the trunk; There was no significant difference between individuals with and without core dysfunction.
