In our younger years, many of us likely heard the expression “Practice Makes Perfect.” This usually came from a parent, coach, or teacher. Some took the saying a step further, adding “Perfect Practice Makes Perfect.” Some even say, "Practice Makes Permanent". Regardless, still the message was clear – if you want to improve, you need to put in some time and focused effort. You need to practice.

But is all about simply practicing or do we need to have a different focus?

Research has provided a better understanding of how practice influences skill development, helping us understand how the nervous system is rewired during the process. While there are many components to consider during the process of motor learning and skill acquisition, in this article we will be discussing how a unique tissue to the nervous system called myelin plays a critical role in the acquisition and mastery of skills.

Practice Rewires the Nervous System
When we are exposed to a movement or sport skill that is new or unfamiliar, the result is typically feeling awkward and uncoordinated. To some degree, we may be apprehensive. This is normal and to be expected. But, as we practice, something happens. Things get smoother, we feel more comfortable, and the movement/skill becomes more natural.

What is happening?

What practice is actually doing is rewiring your nervous system to become more efficient during complex movement tasks through a process called myelination.

The Role of Myelin
Understanding all the intricacies of the nervous system is not the point of this article, but a little background will be helpful. Myelin is a tissue that covers our neurons, the cells that make up the nervous system. Myelin is mostly a fatty substance, with cholesterol being an essential component. It serves to insulate nerve cells and has a characteristic “white” appearance. This is why most people refer to myelin as “white matter” when discussing the nervous system. What science has helped us understand is that myelin improves the speed and strength of nerve signals, meaning that myelinated nerves transmit signals faster than non-myelinated nerves. Myelin helps our nervous system function at a higher level.

Ok, so how do we get myelin onto our nerves?

To begin with, the majority of myelination occurs during the early stages of development. These stages of development occur during the 2-3 years after birth and into early childhood. Children are myelin-generating machines. This can be seen not only in respect to movement, but also with language and comprehension skills as well. Where there is development, you will find myelin. This is why there are critical developmental stages that exist in long-term athletic developmental (LTAD) models. LTAD models help us understand that we cannot make up for lost time. Sure, as we get older we can continue to generate myelin, but it happens at a slower rate and requires more effort. This is why most young athletes who miss critical developmental stages tend to get passed up later in their athletic careers.

So what’s the big deal about critical developmental stages?

It provides children with graded exposure to skills through practice and repetition. The process of practice and repeated effort triggers a pattern of signals through our nervous system. With time and repetition, myelin is produced to increase the speed, strength, and coordination of these nerve signals. It’s a streamlining effect that your nervous system undergoes due to exposure to a repeated sensory stimulus and motor (movement) output.

Practice Makes Myelin, So Practice With Purpose
Understanding the role of myelination in skill acquisition has tremendous implications. Yes, volume and frequency of practice matters, but myelination makes a case for understanding why quality of practice matters. Practicing with an extreme focus on quality is equally, if not more important, than simply practicing a lot. Don’t just practice to practice. Corrections should be made as they are needed. You don’t want to spent the majority of your time practicing bad habits, as bad habits are hard to correct. Bad habits arguably are not permanent. However, the longer they exist, the harder they are to unlearn. Myelin is a big reason why.

In the context of training and sport skill development, if you lift/sprint/jump/practice with poor technique and no one corrects your mistakes, you will be myelinating those nerve pathways – which does you no good and only serves to lowering your athletic potential. Sure you may improve, but you will never reach your true potential. And the longer your bad habits remain, the harder it is to correct them.

The takeaway: practice of movement skills over time causes specific neural pathways to work better via myelination. To improve your performance, you not only need to practice FREQUENTLY, you also must practice CORRECTLY and receive plenty of feedback from a qualified coach so you are able to properly develop your movement and sport skills.

Training Hard vs Training SmartThere are many components to consider when looking to promote proper recovery and restoration from training, be it from sport training or simply the goal of personal fitness. Similar to the considerations made in program design, one must be smart about the tools or tricks they use when it comes to nutrition, rest, and restoration techniques. In my personal experience, the overwhelming majority of individuals who train and compete on a regular basis commonly lack an understanding of recovery methods that are only going to help them optimize their training outcomes. They focus so much attention on their actual training, but fail to bring the same level of focus and attention to detail when it comes to nutrition or even proper sleep habits. When this occurs, training results are typically limited. There becomes a greater resistance to progress, leaving many in this situation feeling frustrated and confused. This is exactly why the understanding of rest and restoration must be passed on to the client or athlete. Yes, there is a difference between rest and restoration.

Basically, rest implies sleep or doing something restful, such as a nap or relaxing while watching the game. However, rest does not guarantee restoration, or the recovery and renewal of the body’s systems (i.e. cardiorespiratory, neuromuscular, endocrine, immune, etc.) from training demands. Not all systems recover in the same time frame and their restoration needs will be dictated by training volume and/or intensity. For the purposes of this article, we are going to discuss the application of recovery and restoration methods as they apply to recovery of the nervous system, specifically the autonomic nervous system.

Keep in mind, it is the current state of the autonomic nervous system that should dictate both training load and restoration methods. Meaning, it should be determined whether an individual is in a state of sympathetic or parasympathetic dominance. The ability to recognize this is crucial in decision making and avoiding inappropriate training loads or restoration methods, as these can push you down the wrong path. Ideally, restoration methods should be as individualized as the training process if your goal is optimal results. But, in general, here are some guidelines that will help you identify where you may fall on the sympathetic-parasympathetic spectrum and how to apply restoration methods to bring you back into an optimal state of recovery.

A) Parasympathetic Dominance (most typically experienced by endurance athletes)

• Signs and Symptoms: chronic tiredness or heavy fatigue, low motivation to train, low resting heart rate, low blood pressure, low libido.

1. Active Recovery Training: The goal is to increase blood flow to the peripheral musculature, speeding up processes of aerobic metabolism inherent in recovery. These activities should ideally be of low muscular and metabolic load, such as an easy bike, swim, or circuits of body-weight exercises.  Avoid high CNS demands, keeping active recovery sessions within 20-30 minutes.
2. Intensive Deep Tissue Massage: Deep tissue massage will up-regulate the sympathetic nervous system through increased proprioceptive input to CNS, which will influence changes in the state of the autonomic nervous system as well as the myofascial system.
3. Cold Water Immersion: May reduce perception of fatigue and soreness after training sessions by up regulating the sympathetic nervous system.  Repeat 2-5 minutes in cold water for 3-5 rounds.
4. Sauna: Increased core temperature results in increased sympathetic response and speed of metabolic processes. It should be noted that the parasympathetic response increases following sauna use. In general, when looking at recommendations for the use of the sauna to promote recovery, the sauna should be between 180-200 degrees for an optimal response. There are a number of various sauna protocols to aid in recovery. In general, repeat 2-4 rounds of 5-10 minutes in the sauna, followed by a cool shower rinse.

• Signs and Symptoms: elevated resting heart rate, elevated blood pressure, poor sleep, mood changes such as being more irritable, suppressed appetite, restlessness, poor or declining performance, low libido.

1. Active Recovery Training: Yes, this has similar application and can be used in either parasympathetic or sympathetic dominance. Follow the guidelines as previously mentioned.
2. Relaxation-based Massage: Soft, gentle touch can generate a powerful parasympathetic response. Massage with the targeted goal of promoting relaxation will down-regulated the sympathetic nervous system. Again, this is achieved through proprioceptive input to CNS.
3. Hot Tub: Hot water immersion promotes relaxation and increased parasympathetic response. Greatest benefit is achieved when water temperature is around 102 for 10-20 minutes.
4. Deep Water Floating and/or Swimming: Not as commonly known or utilized as other restoration methods, this method is exactly what it sounds like, floating in deep water. Deep Water Floating’s benefits come from the proprioceptive changes due to the body being unloaded from gravity. A common recommendation is to alternate between 5-10 minutes of swimming and 5-10 minutes of floating while using a floatation device to ensure complete relaxation.
