Abstract :
The intensity of stretching is rarely reported in scientific literature. In this study, we examined the effects of stretching
intensities at 30%, 60%, and 90% of maximum range of movement (mROM) on the inflammatory response of the right
hamstring muscle. Methods: A randomised within-subject trial was conducted with 11 healthy recreationally active
males over a three week period. Participants were strapped into an isokinetic dynamometer in the supine position, with
the right knee fastened in a knee immobilizer. After randomising the ROM percentages, the hamstring muscle was
moved to one of the three chosen ROM percentages for that week and held there for 5 x 60 seconds followed by a 10
second rest between repetitions. A 5ml blood sample was collected pre-, immediately post, and at 24 hours post
intervention for high sensitivity C-reactive protein (hsCRP) assessments. Results: Significant increases in hsCRP levels
were observed between 30% mROM and 90% mROM (p=0.004) and 60% mROM and 90% mROM (p=0.034), but not
between 30% and 60% (p > 0.05). Conclusions: Muscle stretching at submaximal levels does not elicit a significant
systemic inflammatory responses.
