ENHANCING MOTOR LEARNING WITH SLED TRAINING JOEL BERGERON, MS, CSCS,*D, USATF-2 S trength and conditioning programs for athletic performance can be broken into two main components—physiologic improvement and motor learning. While physiologic enhancement to strength, power, and endurance play a role in athletic success, they are relatively easy things to improve with consistent training. Sport-specific skill acquisition such as swinging a bat or shooting a basketball, however, takes thousands of quality repetitions in order to master and generally progress at a slower rate. Most coaches do not realize that strength training, plyometrics, and core conditioning all contribute to motor learning, when used appropriately. When analyzing movement patterns, the human body moves through three planes of movement; sagittal (flexion/extension motions), frontal (ab/adduction motions), and transverse (rotary) (1). All movements take place in one of these three planes no matter how simple or complex, or utilize a combination of them simultaneously. Most strength and conditioning programs are made up primarily of exercises taking place in the sagittal plane against the vertical pull of gravity. Teaching athletes how to move more efficiently is more than just adding frontal, transverse, unilateral, or bilateral exercises into a program. It also has to do with the progression of movement patterns athletes learn, the combinations of movements participated in when exercising, and what is most commonly overlooked—the line of pull. This enhances neurological learning, but even more importantly, brain plasticity, or the ability of the brain to synthesize new movement patterns at a faster rate (2). Brain plasticity is promoted by teaching 8 the nervous system a greater number of ways to create motor pathways, which send signals out to the muscular system (2). Motor learning as a principle is analogous to trails created in a forest by animal traffic. The less a path is traveled, the more difficult it is to traverse the course due to forest overgrowth. The more a path is traveled, the greater the ground is worn, and if more routes from point A to point B are created, the animal can find a path to the destination in a shorter period of time. The nervous system works in a similar manner. The challenge is figuring out an efficient way of teaching athletes how to create plasticity through the training prescribed. Exposing athletes to a variety of movement patterns that simulate actual sport mechanics can enhance and shorten this learning process. IDENTIFYING FUNDAMENTAL SPORT MOVEMENT PATTERNS Most sports involve three common sport movements; swinging an implement, throwing an object, and a form of locomotion seen as linear, lateral, or a combination (agility) of the two. The difficulty is breaking these movements into simpler patterns that can be taught using conventional strength training and muscular conditioning. But even beyond this, the greatest challenge is finding exercises and routines that actually translate back to sport moves. Performing a squat, bench press, jump, or simple medicine ball throw are all good ways to begin teaching
