Correlation between Heart Rate Recovery,Maximal Oxygen Uptake,and Peak Oxygen Pulse in Healthy Adults Aged 30 to 50
This study aims to investigate the relationship between heart rate recovery(HRR)and maximal oxygen uptake(VO2max)and peak oxygen pulse(O2 Ppeak)in a population of healthy adults aged 30 to 50.A total of 200 participants(105 males,95 females)were recruited,and their height,weight,and body fat percentage were measured.Data on VO2max,O2 Ppeak,and HRR were collected through a cardiopulmonary exercise test.The results showed that HRR1 had a low positive correlation(r=0.461,P＜0.01)with VO2max and a low positive correlation(r=0.427,P＜0.01)with O2 Ppeak.HRR2 had a moderate positive correlation(r=0.612,P＜0.01)with VO2max and a moderate positive correlation(r=0.557,P＜0.01)with O2 Ppeak.Females had lower values of VO2max,O2 Ppeak,HRR1,and HRR2 compared to males.In conclusion,HRR2 shows a moderate positive correlation with both VO2max and O2 Ppeak.Considering its simplicity and non-invasiveness,HRR2 measurement can be considered for inclusion in routine exercise training monitoring.
