Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The changes in step length asymmetry after prolonged effort in running on a treadmill. | Several measurements during 20-30 minutes run. | Step length will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in contact time asymmetry after prolonged effort in running on a treadmill. | Several measurements during 30 minutes run. | Contact time will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in flight time asymmetry after prolonged effort in running on a treadmill. | Several measurements during 30 minutes run. | Flight time will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in hip angles asymmetry after prolonged effort in running on a treadmill. | Several measurements during 30 minutes run. | Hip angles will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in knee angles asymmetry after prolonged effort in running on a treadmill. | Several measurements during 30 minutes run. | Knee angles will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in vertical ground reaction force asymmetry after prolonged effort in running. on a treadmill | Several measurements during 30 minutes run. | Vertical ground reaction force will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
| The changes in ground reaction impulse asymmetry after prolonged effort in running on a treadmill. | Several measurements during 30 minutes run. | Vertical ground reaction impulse will be recorded by the v-gait analysis system during the running test for 20 seconds at certain points of the run: minute 0, 5, 10, 15, 20, 25, 30. If the subject will ask to stop the run, 20 seconds will be recorded prior to the termination of the run. |
