TY - JOUR T1 - Evidence for complex system integration and dynamic neural regulation of skeletal muscle recruitment during exercise in humans JF - British Journal of Sports Medicine JO - Br J Sports Med SP - 797 LP - 806 DO - 10.1136/bjsm.2003.009852 VL - 38 IS - 6 AU - A St Clair Gibson AU - T D Noakes Y1 - 2004/12/01 UR - http://bjsm.bmj.com/content/38/6/797.abstract N2 - A model is proposed in which the development of physical exhaustion is a relative rather than an absolute event and the sensation of fatigue is the sensory representation of the underlying neural integrative processes. Furthermore, activity is controlled as part of a pacing strategy involving active neural calculations in a “governor” region of the brain, which integrates internal sensory signals and information from the environment to produce a homoeostatically acceptable exercise intensity. The end point of the exercise bout is the controlling variable. This is an example of a complex, non-linear, dynamic system in which physiological systems interact to regulate activity before, during, and after the exercise bout. ER -
