4.2. Study Protocol
Patients in the NW group underwent a moderate-intensity Nordic walking training cycle (60–70% of HRmax) for a period of 6 weeks. Venous blood samples were collected from all participants at baseline (I—before the start of the project), in the middle of the training cycle before the training session (II—3 weeks), after the completion of the project (III—6 weeks), and 3 weeks after the completion (IV—9 weeks, follow up).
