MRI diffusion of rotator cuff muscle in two different type of training methods of state-level weightlifters
Objective: To compare the rotator cuff muscles changes on MRI Diffusion study between state-level weightlifter who underwent fast isokinetic training (FIT) and traditional isotonic training (TOT) exercise. Methodology: Gender and weight matched subjects were grouped into two types of exercises; FIT...

| Summary: | Objective: To compare the rotator cuff muscles changes on MRI Diffusion study between state-level weightlifter who underwent fast isokinetic training (FIT) and traditional isotonic training (TOT) exercise. Methodology: Gender and weight matched subjects were grouped into two types of exercises; FIT and TOT. Both groups
underwent 24 sessions of training consisted of 3 distinct lifting positions. The trainings
were scheduled 3 times per week for 8 weeks. MRI diffusion was conducted twice, at
pre-training and 1 week post-training completion. The Fractional anisotropy (FA),
Apparent Diffusion Coefficient (ADC) values and eigenvalues between two groups
were evaluated. Results: A total of 22 subjects were enrolled but only 16 subjects
completed the training programmes. Equal number of subjects (n=8) were subjected for
each training programme. There were significant changes of the λ1 in supraspinatous
muscle (SSM), infraspinatous muscle (ISM) and subscapularis muscle (SCM) in FIT
indicate increased in muscles elongation almost in similar pattern. FA values increased
in both training methods for all the muscles except supraspinatous muscle (SSM) in
TOT. Among these, only FA of Subscapularis muscle (SCM) in FIT was statistically
significant. Conclusions: Both FIT and TOT have a potential to be proposed as an
additional mode of training among the experienced weightlifters to improve their
performance. DTI is a good technique to evaluate muscle diffusion changes. |
