简要总结
The aim of the research is to evaluate the influence of physical and cognitive load as pre-mission activity on the soldier's physical and cognitive performance, in compare to physical load alone.
In order to do so, 12 healthy subjects will perform stimulated road march using a virtual reality environment combined with cognitive load and without, and their physical and cognitive performance will be evaluated by tests before and after.
详细描述
12 young, healthy civilian volunteers will participate in this study. After reading and signing an informed consent form, all subjects will undergo medical examination which includes ECG, anthropometric measurements and Vo2max test.
Afterwards, the subjects will perform randomly 3 experimental days, each consist of physical and cognitive performance evaluation before and after simulated road march using a virtual reality environment; once without additional load, once combining cognitive load during the road march, and once without physical load (without march, waiting between evaluations) as control.
The experiment will take place in a dome room, and the systems being used are:
- CAREN high (Computer Assisted Rehabilitation Environment) which screens virtual scene in the dome.
- MOTEK (Motek Medical©, the Netherlands) which is a two track treadmill (for each leg) placed on a rotatable platform.
cognitive tasks for example: navigation, identification and remembering cars/aircraft.

研究组 & 干预措施
research arm
12 young, healthy civilian volunteers will participate in this study. The experiment will take place in a dome room.
The experiment will be performed according to the protocol of using CAREN and MOTEK systems:
- CAREN high (Computer Assisted Rehabilitation Environment) which screens virtual scene in the dome.
- MOTEK (Motek Medical©, the Netherlands) which is a two track treadmill (for each leg) placed on a rotatable platform.
each subject will undergo the same experiment protocol.
干预措施: protocol of using CAREN and MOTEK systems (Other)
结局指标
主要结局
executive function
时间窗: 3 experimental days
executive function will be evaluated based on the validated Trail Making Test (TMT).
cognitive performance (composite)
时间窗: 3 experimental days
grade will be calculated according to the subject's performance in the computerized tests (SYNWIN activity research services) at the virtual reality environment . performance evaluation is based on the parameters: concentration, memory, visual perception, data processing capability, response time and multitasking.
次要结局
- heart rate variability(3 experimental days)
- lactic acid(3 experimental days)
