How reliable are the equations for predicting maximal heart rate values in military personnel?

The purpose of this study was to evaluate the validity and reliability of equations for predicting maximal values of heart rate in military personnel. Methods: 509 (age 29.1±5.5 yrs ; height 180.1±6.6cm ; body mass 83.4±11.3kg ; VO2max 49.7±6.9 mlO2/kg/min) members of the Croatian Armed Forces (CAF) were tested. The graded exercise test (GXT) with gas exchange measurements was used in order to determine maximal oxygen uptake (VO2max) and maximal heart rate (HRmax). Results: The analysis of variance yielded statistically significant differences between seven HRmax equations (p<0.05). The values from Stevens Creek's (HRmax=205-(age/2) and Fox and Haskell's (HRmax=220 - age) equations had the highest correlation with the HRmax obtained by the GXT test. Conclusion: The authors recommend using the HRmax values from the Stevens Creek and the Fox and Haskell equations for the purpose of training, testing and daily exercise routine in military personnel.
