Key result
An equation using weight, body fat, gender, and HRR explains ~85% of variance in VO2max.
Why the study?
To explore the feasibility of post-exercise heart rate recovery indicators for predicting maximum oxygen uptake (VO2max) in healthy adults aged 30-60 years.
Can a regression equation using post-exercise heart rate recovery accurately predict maximum oxygen uptake (VO2max) in healthy adults aged 30-60 years?
Cross-Sectional (n=260)
Randomly divided into model and verification groups
Can a regression equation using post-exercise heart rate recovery accurately predict maximum oxygen uptake (VO2max) in healthy adults aged 30-60 years?
Effect estimate: R2 0.853
p-value: p=<0.01
A regression equation incorporating weight, body fat percentage, heart rate recovery at 2 minutes, and gender can accurately predict VO2max in healthy adults, offering a simpler alternative to cardiopulmonary exercise testing.
May enable simpler VO2max estimation in healthy adults; leaves open prospective validation before clinical adoption.
Objective: To explore the feasibility of post-exercise heart rate recovery indicators for predicting maximum oxygen uptake (VO2max) in healthy adults aged 30-60 years. Methods: 260 healthy adults who did not perform regular exercise were randomly recruited and divided into a model group (n = 200) and a verification group (n = 60). Measure body fat percentage, weight, height and other indicators, and complete a cardiopulmonary exercise test as required to measure VO2max and heart rate recovery (HRR1, HRR2) in the first and second minutes after exercise. Equations are established through stepwise regression method, and the selected optimal equation is tested for back substitution. Results: . Analysis of variance, goodness-of-fit test, VIF test, Shapiro-Wilk test, and Durbin-Watson test indicate that the equation is more reliable; Pearson product-moment correlation analysis, paired t test, and Bland-Altman consistency test indicate that the equation is more valid good. Conclusion: The regression equation established through heart rate recovery after exercise can be used to predict VO2max in healthy adults aged 30-60 years.

Miao et al. (2024) conducted a cross-sectional in Healthy adults without regular exercise habits (n=260). Heart rate recovery (HRR) and body composition metrics was evaluated on Prediction of maximum oxygen uptake (VO2max) (R2 0.853, p=<0.01). A regression equation incorporating weight, body fat percentage, heart rate recovery at 2 minutes, and gender accurately predicted maximum oxygen uptake in healthy adults aged 30-60 years (R2 = 0.853).
