Applicability of ultrasonography for evaluating trunk muscles size in athletes: a study focused on baseball batters.

摘要: [Purpose] Recently, we demonstrated that the thicknesses of trunk muscles measured using ultrasonography were correlated strongly with cross-sectional areas magnetic resonance imaging in untrained subjects. To further explore applicability clinical setting, present study examined correlation between ultrasonography-measured and imaging-measured athletes trained muscles. [Subjects Methods] The at total 10 sites bilateral sides upper, central, lower parts rectus abdominis, abdominal wall, multifidus lumborum 30 male baseball batters measured. [Results] Overall higher than those subjects who participated our previous study. all highly batters. [Conclusion] These results suggest can be used as a surrogate marker for area imaging, have larger
