Treadmill Design in the Study of Non-Motorised Treadmill Subjects

Writer:realleaderfitnessDate:2017-3-1 09:28:39
The treadmill design was a modified version of the original non-motorised treadmill system designed by Lakomy. The non-motorised treadmill consisted of an endless wire reinforced lateral belt that was attached to a metal frame that included a handrail, display unit and vertical metal strut with sliding gauge. A 100-kg horizontal ‘S’ beam load cell was attached to the vertical strut via the sliding gauge, which locked in place to ensure no movement during testing.The sliding gauge allowed the horizontal load cell to be djusted vertically. A ‘Y’ jointed steel wire attached the horizontal load cell to a tether belt worn around the waist of each subject. To minimise errors in force measurement, the tether belt was adjusted to 8 ◦ above the horizontal of the subject’s waist prior to testing using an electronic level . The load cell was calibrated before and after each test using a range of known weights. Treadmill belt speed was monitored by two optical speed photomicrosensors mounted on the rear roller shaft of the treadmill belt.
Treadmill belt speed, distance and horizontal forces were collected at a sampling rate of 10Hz via the XPV7 PCB interface and analysed using the Force 3.0 Software . Data collected were exported to Microsoft Excel ® where the data were synchronised with the team-sport simulation starting time. The horizontal power output was calculated from the product of treadmill belt speed and horizontal force (N) measured from the horizontal load cell.
