Strength training increases the size of the satellite cell pool in type I and II fibres of chronically painful trapezius muscle in females

摘要

Non-technical summaryExercise has been shown to greatly reduce pain in female computer users suffering from neck pain (myalgia), but understanding of differences between healthy and myalgic muscle at the cellular level is poor. We report a large increase in muscle stem cell number in types I and II fibres with heavy strength training in this population. These findings contribute to understanding of the potential of exercise to influence the activity of cells found in the painful skeletal muscle of individuals suffering from myalgia.
