摘　　要：目的了解2型糖尿病（T2DM）患者运动后心率恢复（HRR）情况，探讨其与运动能力的相关性。方法入选经症状限制性心肺运动试验（CPET）结果为阴性的T2DM患者27例（试验组），门诊健康体检者36例（对照组）。测定运动试验后1～4min心率恢复指标（HRRT）及运动能力指标。结果试验组HRRT明显低于对照组，差异均具有统计学意义（P〈0．01）；峰值心率、峰值摄氧量（Peak VO2／kg）、峰值代谢当量（Peak METs）和心率储备（HRRes）也低于对照组，差异均具有统计学意义（P〈0．01）；静息心率高于对照组（P〈0．05）。所有受试者运动后1min心率恢复值（HRR1）与Peak VO2／kg、Peak METs和HRRes均旱正相关（r值分别为：0．40、0．35、0．55，均P〈0．01）。结论T2DM患者运动后心率恢复减慢、运动能力降低，且运动能力同心率恢复呈正相关。Objective To assess the heart rate recovery （HRR） of type 2 diabetes mellitus （T2DM） patients after exercises testing and investigate its relationship with mobility. Methods A total of 27 patients who produced negative results after symptom -limited cardiopulmonary exercise testing （CPET） （the treated group） and 27 healthy subjects （the control group） were enrolled in to the current study. Then the heart rate recovery time （HRRT） and mobility index were measured after testing. Results The treated patients had obviously shorter HRRT than the control （P 〈 0.01 ）, decreased peak heart rates, Peak VO2/kg, Peak METs and heart rate restorations （HRRes） , but higher resting heart rates, compared with the control （P 〈 0. 05）. All participants presented the values of 1 - minute heart rate recovery （ HRR1 ） alter exercises which was positively correlated with Peak VO2/kg （ r = 0. 40, P 〈 0.01 ）, Peak METs （ r = 0. 35, P 〈 0.01 ） and HRRes （ r = 0. 55, P 〈 0.01 ）. Conclusion T2DM patients show slower heart rate recovery and reduced mobility, and a positive correlation exists between them.
