Overview
Brief Summary
Recruit postmenopausal women and randomly assign them to one of four groups: Early Postmenopausal Exercise Group (EE), Late Postmenopausal Exercise Group (LE), Early Postmenopausal Control Group (EC), and Late Postmenopausal Control Group (LC).
All participates will undergo a graded exercise test to determine their maximum oxygen uptake, and vascular function response will be measured immediately after the exercise test. The COP exercise intensity for postmenopausal women will be obtained through the exercise test, and subjects in the EE and LE groups will undergo exercise training at this intensity for a period of three months. Tests and analyses of relevant indicators will be conducted on subjects in all four groups before and after the intervention. The exercise load experiments will be performed on a cycle ergometer.
