Table 2 shows the results of an investigation into how two different types of physical activity affect breathing rate over a 16-minute period.
| Type of exercise | Breathing rate (breaths per minute) | ||||
|---|---|---|---|---|---|
| 0 minutes | 4 minutes | 8 minutes | 12 minutes | 16 minutes | |
| High-intensity cycling | 12 | 28 | 36 | 42 | 42 |
| Gentle stretching | 12 | 14 | 13 | 14 | 12 |
Comment on the differences in the breathing rates during these two types of exercise.
