PURPOSE: To examine the accuracy of practical indirect methods (i.e., recreational football match and estimation equations) in assessing individual maximal heart rate (HRmax) in recreational football players. Sixty-two untrained male participants engaged in a recreational football intervention (age 39.3 +/- 5.8 years, VO2max 41.2 +/- 6.2 ml.kg(-1).min(-1), body mass 81.9 +/- 10.8 kg, height 173.2 +/- 6.4 cm) were tested for HRmax using a multiple approach, at baseline and post-intervention (i.e., in the untrained and trained status, respectively). Observed HRmax was plotted against peak match HR (Match-HRpeak) and HRmax estimated from prediction equations (EstHRmax) at both time-points. RESULTS: In the untrained status, only the 211 - 0.64 x Age and 226 - Age equations showed non-significant (medium-to-small) differences with observed HRmax. The differences between observed HRmax and Match-HRpeak were large (P 0.05). The exception was for the 226 - Age and 211 - 0.64 x Age equations, with values largely higher than Post-HRmax. CONCLUSIONS: This study suggests caution when considering EstHRmax and Match-HRpeak in recreational football interventions to track HRmax. The accuracy of EstHRmax may vary according to training status, suggesting the need for different approaches and equations across training interventions.
