THE DEVELOPMENT OF TRUNK MUSCLES IN MALE WRESTLERS ASSESSED BY MAGNETIC RESONANCE IMAGING
The purpose of this study was to compare the development of trunk musculature among Elite, Sub- elite, and Elite junior wrestlers. The performance level of these groups, ordered highest to lowest, is as followsElite (n = 20), Sub-elite (n = 25), and Elite junior (n = 39). A magnetic resonance imagin...

description | The purpose of this study was to compare the development of trunk musculature among Elite, Sub- elite, and Elite junior wrestlers. The performance level of these groups, ordered highest to lowest, is as followsElite (n = 20), Sub-elite (n = 25), and Elite junior (n = 39). A magnetic resonance imaging device was used to measure the cross-sectional area (CSA) of the trunk muscles. The whole trunk muscle cross- sectional area (t-MCSA) of the Elite group was significantly larger than that of the Elite junior group (p < 0.05). The rectus abdominis muscle CSA of the Elite group was significantly larger than that of the Elite junior group (p < 0.01). The psoas major muscle CSA of the Elite group was significantly larger than that of the Elite junior group (p < 0.05). There were no significant differences in the CSA of any of the trunk muscles between the Elite and Sub-elite groups. In conclusion, compared with Elite junior wrestlers, it is conceivable that a greater CSA of trunk flexors of Elite wrestlers is one factor which supports increased performance. |
