Normal kinesthetic movement occurs in a multiplanar environment at varying speeds and at multiple angles. Many traditional training programs dominate the sagittal plane (divide the body into left and right). For example, some exercises that occur in the sagittal plane are chest press, bicep curl, triceps push down, leg press, leg extension, and leg curl to name a few. These exercises should not be labeled as “bad” however, they are uniplanar and do not allow the body the luxury of moving in the other three planes of motion. Repetitive movement patterns have been shown to facilitate a decrease in neuromuscular efficiency, increase the onset of program plateaus, and increase synergistic dominance resulting in injury.
The term synergistic dominance is merely a fancy term used to describe tight or overactive muscles for example, the gluteus maximus is designed to create concentric hip extension i.e.: back leg prior to a soccer kick and/or free leg on a figure skating jump landing. Now, if through analysis the glutes are not firing properly the hamstrings will then “pick up the slack” in order to create the intended motion. As a result, the hamstrings are then considered synergistically dominant (shortened) and overtime may result in injury. It is extremely important that the PES identify deviations such as these in order to create a program that is both scientifically valid and effective.
