Muscular blood oxygen level-dependent MRI is beneficial to evaluate effectiveness of an exercise prescription.

ABSTRACT:

Background

To determine the feasibility and validity of using blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI) to evaluate the effects of back extension exercise on core lumbar paraspinal muscle strength.

Methods

In this prospective study, R2* and T2 mapping of paraspinal muscles of 100 healthy volunteers were performed before and after back extension exercises in different recovery sessions (session I, II, III or IV). Volunteers use the Roman chair to complete the back extension exercises. The cross-sectional area (CSA), R2* and T2 values were measured and analyzed in 3 muscles (iliocostalis, longissimus, and multifidus muscles) of the lower back before and after exercise.

Results

The CSA and T2 values of iliocostalis, longissimus, and multifidus
