Insights
Heart rate recovery (HRR) did not correlate with central systolic blood pressure (CSBP) in young adults. However, HRR showed an association with augmentation index (AIx), suggesting its potential as a cardiovascular indicator.
Area of Science:
- Cardiovascular Physiology
- Exercise Science
Background:
- Heart rate recovery (HRR) provides valuable cardiovascular insights with minimal cost and technical demand.
- Central systolic blood pressure (CSBP) is a significant predictor of cardiovascular diseases.
- Investigating the link between HRR and CSBP can offer accessible cardiovascular health information.
Purpose of the Study:
- To examine the association between HRR and CSBP in young, healthy individuals.
- To explore the relationship between HRR and augmentation index (AIx).
- To analyze these associations based on sex.
Main Methods:
- One hundred and seven participants (55 men, 52 women) underwent maximum oxygen consumption (VO2max) testing.
- Heart rate recovery was measured at one (HRR1) and two minutes (HRR2) post-exercise.
- Central systolic blood pressure (CSBP) and augmentation index at a heart rate of 75 bpm (AIx@75) were recorded.
Main Results:
- No significant association was found between HRR1, HRR2, and CSBP in the combined group or when analyzed by sex.
- A significant inverse association was observed between HRR1 and AIx@75 in the combined group (r = -0.37, P < 0.001).
- This association between HRR1 and AIx@75 was also significant in both men (r = -0.31, P = 0.02) and women (r = -0.38, P < 0.01).
Conclusions:
- HRR is not associated with CSBP in young, healthy adults.
- Measures of HRR, particularly those linked to parasympathetic activity, are associated with lower AIx@75.
- While HRR may indicate cardiovascular health, it may not be a reliable indicator of CSBP in this demographic.
Purpose:
Measuring heart rate recovery (HRR) holds valuable cardiovascular information and requires minimal technical skill and cost. Understanding the associations between HRR and more robust cardiovascular indicators, such as central systolic blood pressure (CSBP), can provide valuable cardiovascular information with less involvement. CSBP is a strong predictor of certain cardiovascular diseases. The study aims to examine the association between measures of HRR and CSBP and the augmentation index (AIx) in a group of young, healthy individuals and based on sex.
Participants And Methods:
One-hundred and seven participants (men - 55, women - 52) were measured for HRR at one minute (HRR1) and two minutes (HRR2) after maximum oxygen consumption (VO2max) testing, CSBP, and the AIx at a heart rate of 75 beats∙min-1 (AIx@75).
Results:
The Pearson correlation indicated no association between HRR1, HRR2, and CSBP in men and women combined: r = 0.06, P = 0.53; r = 0.05, P = 0.59, respectively, or based on sex: men = r = 0.01, P = 0.95; r = 0.04, P = 0.79, respectively, and women = r = -0.05, P = 0.75; r = -0.09, P = 0.52, respectively. However, there were associations between HRR1 and AIx@75 in men and women combined: r = -0.37, P < 0.001, and based on sex: men = r = -0.31, P = 0.02, and women = r = -0.38, P < 0.01.
Conclusion:
Measures of HRR were not associated with CSBP in a combined group of young men and women or based on sex. Most measures of HRR, especially those established by parasympathetic nervous activity, were associated with lower AIx@75. Though measures of HRR might be good indicators of cardiovascular disease, they might not be good indicators of CSBP in young, healthy individuals.
