Rohat is designed for determining the AlterG treadmill speed that will create the same metabolic cost (energy use) as normal overground running. For example, when the AlterG is set to 80% of body weight, less energy is needed to run a given speed. This program will tell you how fast to run to get the same metabolic cost when running with lower body weights. It will also display the plantar pressure for the situation you create. That tells the expected peak pressure felt under the feet as a percentage of the peak pressure when running at 100% body weight and 10 miles per hour (6:00 min/mi).
