| description | Objective: To evaluate the size of rotator cuff muscles and muscle fiber angle of
supraspinatous muscle in two different types of exercise which are fast isokinetic
training and traditional isotonic training in state-level weightlifters.
Methodology: Subjects (n=16) were recruited through Majlis Sukan Negeri Kelantan.
They were gender- and weight- matched and randomly assigned into traditional isotonic
training group (TOT) and fast isokinetic training (FIT) group. Both groups went through
24 sessions of training programme three times per week for 8 weeks. MRI was done
before the commencement of the training and after the training. MRI of rotator cuff
muscles were performed and measurement of CSA and PA were done. Results: CSAs
of the four rotator-cuff muscles increased after the intervention programme with
significant improvements (p<0.05) found in CSA of supraspinatous muscle (SS) and
infraspinatous with teres minor muscles (ISTM), but not in subscapularis muscle (SC).
Significant increment in CSAs were found in all rotator-cuff muscles of subjects who
underwent FIT but for subjects who underwent TOT, significant increment in CSA was
only found in SS, but not that of SC and ISTM. Pennation angle (PA) of the SS
significantly increased after the intervention programme. Significant increment in PA
was found in all rotator-cuff muscles of subjects who underwent either FIT or TOT.
Conclusions: Fast isokinetic training show significant increment of CSAs and PA of
the rotator cuff muscles. |
