Anti-Gravity Training
jaime luarcazuma que lo tiene en su centro de entrenamiento de boadilla informa
-si no puedes correr por dolor al impacto, puedes seguir corriendo mientras estas lesionado
-puedes correr mas deprisa (con el mismo gesto de esa velocidad) con la consiguiente mejora tecnica
-puedes aumentar el volumen de carrera a pie sin lesionarte.
Anti-Gravity Training: Tool for Performance
The Alter-G treadmill has become more than a tool for rehab

Originally built for astronauts—and once considered a high-tech device accessible only to elite athletes—the Alter-G is showing up everywhere: from gyms in New York City to chiropractors’ offices in San Diego. The anti-gravity treadmill has moved from a means for rehab into the realm of performance enhancement as athletes learn to use it as another tool for training. It’s quickly becoming a popular supplemental exercise mode for endurance athletes thanks to its ability to replicate similar muscle recruitment patterns to running on land, and improve gait mechanics, to name two of its benefits.
Before the Alter-G came around, endurance athletes would use a variety of modes such as pool running, stationary bikes and elliptical machines to provide an overload to the body (whether aerobically or anaerobically )while simultaneously unloading their joints. The only complaint was the fact that different muscles than those used in running where being recruited, and the specificity of training could not be maintained. Recent research has demonstrated that while running on the Alter-G at a lower percent body weight, muscle activity decreases somewhat but the same muscles continue to be recruited. While we don’t want to be strapped to a treadmill for all of our training, when implemented correctly, the Alter-G can provide specificity of training and is a way of achieving multiple types of workouts throughout an entire training cycle. Here are a few ways to put the Alter-G to work for you throughout the year.
Unloading: As defined by the Alter-G methods, unloading is a reduction in ground reaction forces achieved by removing body weight. The primary benefit is that the motor units that drive the muscles have a break and in turn you also give the central nervous system of the brain a rest. Simultaneously, proper gait mechanics are maintained including range of motion which will help minimize any loss of muscle that occurs from not completely bearing your body weight. Unloading is beneficial for gradually bringing injured athletes back, in facilitating recovery workouts for the healthy athlete, or decreasing the stress of a typical workout through the removal of body weight.
Overloading: The first version of overloading that can be performed is by un-weighting the body by 10 percent of body weight in order to run a higher volume of a speed you are attempting to achieve, and then progressively adding two to four percent body weight each week until the run can be achieved at your normal body weight. A second means of overloading is to reduce body weight initially during the run and then re-introduce part or all of your body weight periodically during the session. This can be performed for a variety of sessions from long runs to intervals.
Over Speed Training: Teaching the body to increase its maximum speed over a given distance can lead to significant gains in maximum power—a benefit especially in the last 200-400m of a race. When you subtract body weight, you’re able to run at a higher cadence, making your muscles more familiar with higher speeds. Over time, weight can be re-applied and eventually the higher speeds can be maintained at full body weight.
Improving gait mechanics: Learning to run faster at submaximal paces can often be hampered by fatigue-induced loss of form. A key part of learning to run faster with good form depends on how many times you can perform an activity with proper technique and let the brain memorize the proper recruitment and activity patterns of the muscles. Un-weighting reduces the amount of strain on the body, minimizes fatigue, and helps us achieve more repetitions with good form.
