Strength and Fatigue [PDF]

Nature, 1950
IT is generally thought that the very large forces which isolated muscles can develop when excited electrically would produce movements so violent as to endanger tendons and bones if they were available in voluntary contractions in normal life. Our strength is kept within bounds by the inability of the higher centres to activate the muscles to the full.
