Table 1.
The running and NFB protocols used in this study.
| Week | Running protocol | Neurofeedback protocol | |
|---|---|---|---|
| Run interval | Walk interval | NFB length | |
| 1 | 1:00 | 2:00 | 5:00 |
| 2 | 1:15 | 1:45 | 7:00 |
| 3 | 1:30 | 1:30 | 9:00 |
| 4 | 1:45 | 1:15 | 11:00 |
| 5 | 2:00 | 1:00 | 13:00 |
| 6 | 2:15 | 0:45 | 15:00 |
| 7 | 2:30 | 0:30 | 17:00 |
| 8 | 2:45 | 0:15 | 19:00 |
Each running session consisted of eight 3 min intervals, which were split into varying amounts of running and walking, as shown in the table. The difficulty of the running sessions increased every week by increasing the proportion of time spent running in each 3 min interval. In contrast, the NFB difficulty was increased by increasing the length of time the participants spent performing mindulness-like NFB.
