J Strength Cond Res 25(7): 1983-1988, 2011—The objective of this study was to estimate the oxygen uptake (VO₂) in elite youth soccer players using measures of heart rate (HR) and ratings of perceived exertion (RPEs). Forty-six regional-level male youth soccer players (~13 years) participated in 2 VO₂max tests. Data for HR, RPE, and VO₂ were simultaneously recorded during the VO₂max tests with incremental running speed. Regression equations were derived from the first VO₂max test. Two weeks later, all players performed the same VO₂max test to validate the developed regression equations. There were no significant differences between the estimated values in the first test and actual values in the second test. During the continuous endurance exercise, the combination of percentage of maximal HR (%HRmax) and RPE measures gave similar estimation of %VO₂max (R² = 83%) in comparison to %HRmax alone (R² = 81%). However, the estimation of VO₂ using combined %HRmax and RPE was not satisfactory (R² = 45-46%). Therefore, the use of %HRmax (without RPE) to estimate %VO₂max could be a useful tool in young soccer players during field-based continuous endurance testing and training. Specifically, coaches can use the %HRmax to quantify internal loads (%VO₂max) and subsequently implement continuous endurance training at appropriate intensities. Furthermore, it seems that RPE is more useful as a measure of internal load during noncontinuous (e.g., intermittent and sprint) exercises but not to estimate %VO₂max during continuous aerobic exercise (R² = 59%).
