10. Exerbotics: Computer-Controlled Machines
One of the most exciting applications for strength and body composition are from a company called Exerobotics. These Dynokinetic (think moving isometrics -yes that's an intentional contradiction) machines are the gym equivalent of advanced lab equipment -and essentially make traditional training obsolete. They use computer-controlled movement such that the handles move (at any specific desired speed) whether you're on them or not. Though his may sound silly, it's both brilliant and physiologically ideal. The reason is that we can, and should, take full advantage of the eccentric component of each rep. This can only be done if we are able to exert as much force as possible, which is impossible on most machines. The reason being that if we're exerting more force than is on the bar (or plate stack) then we're going to be moving the weight in a concentric motion[see the Eccentric article in this issue for more information]. Due to the computer controlled movement, Exerbotics allows you to push as hard as you can, in both the concentric and eccentric phases, ensuring that you're getting the most out of every rep.
One of the most prolific strength training researchers of our time, from the University of Connecticut, Dr. William Kraemer, was an integral part of Exerbotics development. He states: "Exerbotics Strength Training Systems will cause a huge, pervasive and virtually incalculable effect when it hits the market." Such high praise from a legendary source does not come without good reason. One of the main features of the computerized Exerbotics system is that everything is measured, including the force exerted through every millisecond of every rep. This will allow you to standardize your training in a way never before possible. Incredibly, as complicated as it sounds, it's all quite interactive and user friendly. With a few simple presses on the touch screen you're ready to go.
The other remarkable aspect of the Exerbotics system is the type of workout you can get. The rep speed and range of motion are preset and completely controlled. All you have to do is apply the program that's ideal for your goals (which is exactly why you're reading M&F). After performing your 1RM test the first time you use the machine, you'll see a graph on the monitor of your strength throughout the entire rep. After that, simply determine what % of that 1RM you want to train at, and the Exerbotics will display the appropriate line graph corresponding to that level of force. For example, if you want to train at 80% 1RM, simply plug that number into the machine and the line graph will be generated for you. When the set begins, all you have to do is match your force output to the line on the screen and you're training at exactly the predetermined level. This is real time visual feedback at its best.
A final quote comes from Dr. Kent Noffsinger who developed this impressive line: Exerbotics fitness stations fully adapt to the user and are very light-weight since there are no weights or weight stacks. The resistance force provided during exercise is independent of "impingement point" position or motion - it is determined by user effort at every instant and adjusts instantly and continuously. Exercise protocols can be user-designed and programmed - comprehensive performance data is recorded, analyzed, and reported as desired.
Although they're not cheap, with the ~$10,000 price tag comes ideal strength and hypertrophy training. This is the gym of the future.
