Quantification of the relationships between volume and intensity of exhaustive treadmill running in active young men

ABSTRACT: Aim: Quantifying the relationship between volume and intensity as key components of training is a precise manner that is complicated for most coaches.  The aim of this study was to quantify the inverse relationships between training volume and intensity during exhaustive treadmill running among active young men. Method and Material: 32 active young men aged 21 years selected as subjects and completed four exhaustive treadmill running in the four separate phases at 70%, 80%, 90%, and 100% VO2 with at least 72 hours rest intervals. The inverse relationship between volume and intensity of exercise was analyzed by the non-linear regression. Results: The results showed that the inverse relationship between volume and intensity of exhaustive treadmill running obeys a second-order polynomial regression where the volume of exercise (VE min) is a function of exercise intensity (EI beat/min) (VE min= 0.0225(HR beat/min) 2 – 9.4672 (HR beat/min) +997.91). Conclusion: It can be concluded that the inverse relationship between volume and intensity of exhaustive treadmill running is non-linear and the fitted equation can be used to predict the volume of exercise based on the exercise intensity among active young men.
