The Influence of Running and Velocity to Kinematic Parameters

Study Overview
=================
Brief Summary
-----------------
Some researches have found that gait posture velocity have influence on kinematic parameters. However, how the gait velocity and posture will influence kinematic parameters remain unclear. In addition to walking, running is one of the most daily activities of people. The purpose of this research is to find out the influence of gait velocity and running to kinematic parameters . To do this, it will provide a reference for future prospective studies or investigations and make us fully understand the impact of gait velocity and running to kinematic parameters of gait.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| WV 1<br>The condition of this group will be set as participants walking at 3.5km/h | Procedure: Walk and Run<br>* Once participants are eligible, they will undergo the experimental procedure. Before data collection, they will walk or run on a treadmill in barefoot for ten minutes to adapt the condition. The a gait analysis system will collect the data while they walk or run on the treadmill in barefoot at selected gait speed.<br>|
| WV 2<br>The condition of this group will be set as participants walking at 4.0km/h | Procedure: Walk and Run<br>* Once participants are eligible, they will undergo the experimental procedure. Before data collection, they will walk or run on a treadmill in barefoot for ten minutes to adapt the condition. The a gait analysis system will collect the data while they walk or run on the treadmill in barefoot at selected gait speed.<br>|
