Objective
The objective of this study was to identify the optimal relative intensity to predict speed associated with maximal heart rate (vHRmax) in recreational runners during 10-km race.

Equipment and methods
Fifty-nine male, recreational runners volunteered to participate. Participants were submitted to a maximal incremental test to determine peak treadmill speed (Vpeak) and vHRmax (75, 80, 85 and 90% HRmax) based on di Prampero (1986) and Lacour et al. (1990, 1991) methods. They also performed a 10-km performance in track.

Results
No differences were observed between percentages of HRmax for vHRmax based on Lacour et al. (1990, 1991), except for the vHRmax-75% that was higher than the other percentages. The vHRmax determined by the di Prampero (1986) method was lower than both Vpeak and vHRmax of Lacour et al. (1990, 1991) method for all percentages of HRmax. The vHRmax-75% of Lacour et al. (1990, 1991) method was different from Vpeak. The vHRmax-85% and vHRmax-90%, independently of the method, were highly correlated to 10-km running velocity. In conclusion, vHRmax-85% and vHRmax-90% calculated by Lacour et al. (1990, 1991) method appears to be the most adequate method to determine vHRmax, since it was closer to Vpeak and highly correlated to performance.
