Effects of isometric contraction on intramuscular level of neuropeptide Y and local pain perception.
The release of neuropeptide Y (NPY) is reported to increase in ischemic conditions and may thus be involved in chronic myalgia. The purpose of this study was to investigate the effect of isometric contraction on intramuscular levels of NPY in relation to local pain development. ⋯ Pain is developed in the trapezius and masseter muscles during repeated isometric contraction. The NPY level is increased in the trapezius muscle but is not associated with the pain development.
