Wyatt, FB and Swaminathan, A. Implementing a mathematical model to compare oxygen uptake kinetics between cyclists and noncyclists during steady state. J Strength Cond Res 24(10): 2627-2631, 2010-The purpose was to compare a mathematical model of oxygen uptake and bioenergetic systems to an experimental protocol. Twelve (N = 12) noncyclists (NC), age 21.8 +/- 1.4 years), and 8 (N = 8) cyclists (C), age (30.5 +/- 5.7 years), were subjects. All subjects signed an informed consent. Oxygen consumption (V) over dotO(2), ml.kg(-1).min(-1)) was measured with steady-state (V) over dotO(2) requirements and responses determined using the mathematical model from the following equation (V) over dotO(2) (WR) = (V) over dotO(2) (rest) + (V) over dotO(2) (unloading pedaling) + alpha.WR; (V) over dotO(2) (WR) = (V) over dotO(2) means ( SD) included the following: V Delta(V) over dotO(2) = Delta(V) over dotO(2) (WR) = [1 = e([-t-td)/tO2])]. Exercise means (SD) included the following: (V) over dotO(2)NC(WR) = 48.4(16. 6) ml(-1) . min(-1) for NCs and (V) over dotO(2)C(WR) = 56.4(24.95) ml(-1).min(-1) for Cs; Delta(V)o(2)NC (t,WR) = 6.38 ml(-)1.min(-1) for NCs and Delta(V) over doto(2)C(t; WR) = 7: 44 ml(-1).min(-1) for Cs. The correlation between the mathematical model and actual measure was statistically significant (p<0.01) with a coefficient of r = 0.947. The experimental protocol was significantly associated with the mathematical model. This allows for a quantitative analysis and safe prediction of steadystate oxygen uptake conditions on populations before exposure to exercising conditions. Through more precise analysis of conditions, greater specificity of training may lead to more predictable adaptation outcomes.
