SHR # 2845:: No Time to Exercise? What About 3 Seconds a Day? - Professor Ken Nosaka, Ph.D. - A new study from the Edith Cowan University in Perth Australia provides conclusive evidence that the most effective way to build muscle and strength is through controlling the eccentric or negative portion of the weight’s movement when you use heavy weight. When compared to concentric and static holds with heavy weight, the eccentric portion of the movement elicits the greatest protein synthetic response and the greatest neuromuscular adaptations. So much so that spending as little as 3 seconds fighting the weight as you lower it is all you need to spark muscle growth. Arthur Jones first postulated this in the 1960’s and was a consideration that influenced the early development of Nautilus and it’s cam-lobe leveraging systems. Today ARX (Adaptive Resistance Equipment – http://shrnetwork.biz/arx ) exploits this phenomenon better than any other equipment company on the planet. No one wants to spend unproductive time in the gym. If that sounds like you, then a greater focus on negative or slow heavy eccentric reps is a must addition for your training program.
