Previous work has shown that a correlation exists between both the degree of ischemia and the intensity of pain with the strength of contraction in a tonically contracted muscle. Also, it has been demonstrated at the degree of muscle ischemia is related to the intensity of induced pain. These observations might lead to the conclusion that the pain caused by ischemia limits the endurance of the muscle contraction. An analgesic agent, known to reduce ischemic pain was shown to have no effect on the endurance or strength of a tonic muscle contraction. This was interpreted as demonstrating a lack of causally in the relationship between pain due to ischemia and muscular work decrement.
