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.
