Abstract text INTRODUCTION:
Monitoring heart rate is a prevalent method used in athletics to gauge physical training intensity and recovery in order to produce optimal adaptations. To quantify heart rate training load, summated heart rate zone (SumHR) scores have been utilized by calculating the duration spent in 5 heart rate zones during an activity (1). Advanced physiological measurements (e.g., metabolics, biomarkers) have been previously used in military populations to quantify the physiological demands required to perform high physically demanding military tasks; however, calculating SumHR scores have not been extensively investigated in military populations performing physically demanding occupational tasks. To determine the relationship between total absolute oxygen consumption (AbsVO2) and SumHR scores in Soldiering tasks.
METHODS:
Monitoring heart rate is a prevalent method used in athletics to gauge physical training intensity and recovery in order to produce optimal adaptations. To quantify heart rate training load, summated heart rate zone (SumHR) scores have been utilized by calculating the duration spent in 5 heart rate zones during an activity (1). Advanced physiological measurements (e.g., metabolics, biomarkers) have been previously used in military populations to quantify the physiological demands required to perform high physically demanding military tasks; however, calculating SumHR scores have not been extensively investigated in military populations performing physically demanding occupational tasks. To determine the relationship between total absolute oxygen consumption (AbsVO2) and SumHR scores in Soldiering tasks.
RESULTS:
For SBF and SBC, significant positive correlations exist between AbsVO2 and SumHR (r=0.75, p=0.01; rho=0.82, p<0.01). AMMO had a significant positive r=0.82 (p<0.01) but nonsignificant rho (p=0.07). No significant correlations were revealed for FM (p=0.27).
CONCLUSION:
A linear relationship exists between the total absolute oxygen consumption and SumHR scores, indicating individuals with higher AbsVO2 values tended to have higher SumHR scores. Calculating SumHR scores may be an acceptable and feasible alternative to metabolic measurements when attempting to assess the physiological demands during Soldiering tasks; however, caution should be used for constrained tasks (e.g., treadmill FM) due to the potential inability to detect significant performance differences.
