SPRINTS ON THE S-DRIVE PERFORMANCE TREADMILL
The S-Drive is a motorless treadmill made by Matrix. Unlike most treadmills where motor powers it and all you’re doing is picking your legs up, this treadmill you have to power by actively pushing to move it just like running outside. This, like running outside, forces the hip extensor muscles to work. On a regular treadmill, they don’t get worked at all.
Another very cool feature with the S-Drive is you can increase the resistance. This would be comparable to pulling a sled behind you while sprinting, which can be a good way to increase sprinting speed depending on a lot of variables.
We use the S-Drive for many different things ranging from training for speed or power to incorporating it into a circuit with other exercises for conditioning or fat loss. One thing we’ve recently been doing is connecting a Push Band device to the ankle to measure the velocity measured in meters per second. We can play around with how much rest someone needs to be based on what the training goal is and whether or not they’re losing speed. For example, if the training goal is to maximize velocity we can see if they’re losing speed, and if so, give them more rest between sets to fully recover to do repeated efforts as fast as possible.
Here is a video of one of my karate athletes performing around 8-10 second sprints at the end of his workout.
