Studies with arm ergometer (AE) training have shown benefits in the functional capacity of patients with peripheral arterial disease (PAD) bypassing the main barrier to exercise in these patients, pain during walking exercise. The only study that proposed to investigate the mechanism involved in this adaptation observed that chronically training with EB promoted improvement in the oxygen saturation (StOâ‚‚) of the leg muscles during walking. However, how arm exercise could improve leg muscle StOâ‚‚ remains unknown.
The goal of this study is to analyze what happens during AE on the tissue oxygen saturation (StOâ‚‚) of the leg affected by PAD.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Arm crank exercise | The exercise session will consist of 15 sets of 2 minutes of exercise in arm ergometer with an intensity equivalent to 13-15 on the Borg's perceived exertion scale. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Arm crank exercise | Other | The arm ergometer exercise will be the only intervention implemented during the study. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Calf Muscule Oxygen Saturation (%) | The parameters of calf muscle oxygenation will be collected using the non-invasive Near-Infrared Spectroscopy (NIRS) technique, with an NIRS spectrometer and a dedicated laptop computer. The NIRS sensor will be placed on the calf region, on the leg with the lower ankle brachial index, at the level of the largest calf circumference. The equipment will be programmed for continuous recording throughout the experimental session, covering the pre-exercise, during exercise with arm ergometer, and post-exercise periods. | Just before, during 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 minutes of exercise, and after 10 minutes of exercise. |
| Measure | Description | Time Frame |
|---|---|---|
| Oxyhemoglobin (micromol) | The parameters of calf muscle oxygenation will be collected using the non-invasive Near-Infrared Spectroscopy (NIRS) technique, with an NIRS spectrometer and a dedicated laptop computer. The NIRS sensor will be placed on the calf region, on the leg with the lower ankle brachial index, at the level of the largest calf circumference. The equipment will be programmed for continuous recording throughout the experimental session, covering the pre-exercise, during exercise with arm ergometer, and post-exercise periods. |
