Relationship between Cross-Sectional Area and Function of Core Muscles: An MRI Study

Background Particular attention has been paid to the core muscles because they serve as a muscular corset that works unit stabilize body and spine. Training programs for improving stability often target strength endurance. Increased muscle size is also an expected effect of training programs. However, relationship between cross-sectional area (CSA) strength, stability, clinical test scores not identified. Purpose To investigate CSA functions (strength, endurance, stability). Study design A study Methods Fifty healthy participants (24 men, 26 women) participated in this study. The was measured using MRI. Maximal isometric trunk flexor score double leg loading were used measure function. function examined by Pearson’s correlation coefficient Spearman rho coefficient. Results side bridge positively correlated with CSA. endurance showed positive except test. Conclusions Only moderate excellent These findings indicate achieve hypertrophy could lead improved but
