Researchers analyzed the hamstring flexibility of 60 subjects and performed a battery of tests to assess neck strength.
Compared to the subjects with flexible hamstrings, the subjects with reduced hamstring mobility demonstrated significantly poorer scores on tests of neck muscular endurance and strength.
Conclusions
Limited mobility at the hip may reflect biomechanical disruptions of the kinetic chain that can manifest in reduced function at the neck or other regions of the body.
