The second half of the test involved subjects performing a 100-m sprint on a man-made track using radar to measure the forward speed of runners to create velocity-time curves. The main result of this study showed that the force application technique (rather than simply the total amount of force applied) is the key determinant factor in ...
A training sled, weight sled, or fitness sled is a piece of exercise equipment that provides resistance as the user pushes, pulls, or otherwise moves the sled along a flat surface. [1] Commercial sleds allow easily adjusting the weight or resistance and are supported on feet or wheels that allow moving the sled across surfaces such as grass ...
It is classed as a retro movement, the reverse of a normal movement. Backward running is a less-natural motion but can be accomplished with some speed with practice. It is better to start out backward walking (also called retropedaling), which is relatively easy, and increase speed over time.
A luge / l uː ʒ / is a small one- or two-person sled on which one sleds supine (face-up) and feet-first. A luger begins seated, propelling themselves initially from handles on either side of the start ramp, then steers by using the calf muscles to flex the sled's

The contribution of active muscle work increases with the walking speed. Despite the fact that a certain amount of energy is consumed for the arm movements, the total energy consumption drops meaning that arm swing still reduces the cost of walking. That reduction in the energy is up to 12 percent at certain walking speeds, a significant saving.
I tried the test out with Bonnes as my timekeeper. She told me I walk 3.14 meters per second because I completed the test in 1.91 seconds. That is faster than average for my age group, and ...
