DESCRIPTION:A Minimal Physiological Model for Human Running Performance\nTh
 orsten Emig (LPTMS\, Université Paris-Sud)\n&nbsp\;\n\nMeasurements of ph
 ysiological variables during exercise and performance evaluations and pred
 ictions are important for a fundamental understanding of physiological pro
 cesses\, training and assessment of athletes\, and beyond sport in the stu
 dy of complex physiological response related to aging\, muscular structure
  and cardiovascular health. Models for human running performances of vario
 us complexities and underlying principles have been proposed\, often emplo
 ying a combination of data for world record performances and concepts that
  are not always based on simple principles of human physiology. We present
  a novel\, minimal model for human running performance that follows from a
  self-consistency relation for the time dependent power output during raci
 ng events. The model has a total of four parameters that are not fixed a p
 riori and characterize individual physiological profiles for a runner. The
  analytic approach presented here is the first to derive the observed loga
 rithmic scaling between world (and other) record running speeds and times 
 from basic principles. Various female and male record performances (world\
 , national) and also personal best performances of individual runners for 
 distances from 800m and to the Marathon are excellently described by our m
 odel\, with mean absolute errors of (often much) less than 1%. Physiologic
 al parameters of our model\, as obtained from records and individual runne
 rs\, are consistent with existing laboratory measurements. The computed ma
 ximal power output that can be sustained for a given time describes well e
 xisting experimental data for the time to exhaustion dependence of suprama
 ximal oxygen consumption in the anaerobic regime. Our model is used to def
 ine and estimate endurance for both the aerobically and anaerobically domi
 nated performances. As an application of our model\, we derive personalize
 d training speeds for prescribed duration and intensity. Our findings coul
 d be a basis for plethora of further studies including assessment of perfo
 rmance dependence on age\, altitude\, muscular structure\, specialization 
 of athlete\, racing strategies\, and optimal dosing of recreational exerci
 se.
