The aim of the present pilot study is to investigate the feasibility of an exercise pressure response approach for assessing physiological strain during BFR training in a clinically supervised setting. Patients undergoing rehabilitation following total knee arthroplasty (TKA) will be included. The results are intended to contribute to an improved evaluation of load management during BFR training.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Low Load | Experimental | Low Load (LL-BFR) The first group will perform cycle ergometer training with BFR at a low individual intensity (40% of heart rate reserve [HRR]) as the first session. One week later, the patients will complete the second exercise session using the protocol of the "HL-BFR" group. |
|
| High Load | Experimental | High Load (HL-BFR) The second group will perform cycle ergometer training with BFR at a higher individual intensity (60% of heart rate reserve [HRR]) as the first session. One week later, the patients will complete the second exercise session using the protocol of the "LL-BFR" group. |
