A common belief in professional sports is that established athletes are unable to change their playing style once they reach a certain age. However, what is considered “old” in sports, such as being in one’s thirties, is still relatively young from a lifespan perspective. At this stage, the brain is fully capable of developing new or adapted neural networks to support newly acquired motor skills. Research on adults aged 18 to 30 shows a consistent, positive link between chronic physical activity and the ability to learn new upper limb motor skills [13]. Even in older adults, aged 60 to 94, the relationship, though less strong, remains positive. Therefore, being in your thirties and regularly engaging in sports can greatly facilitate the learning of new motor skills. Researchers have suggested that it takes three to five months of consistent repetition for a new movement to become automatic [14]. During this time you undergo different phases of learning. In the first couple of days you will most likely activate more muscle groups and more areas of your brain than needed, thus leading to unnecessary movements. With time, your quality and smoothness of movement will improve drastically and the irrelevant movements slowly disappear while the neurons that are responsible for the necessary movements gradually build and strengthen their connections. After three to five months the movement becomes automatic, but this automatism will most likely never be perfect and susceptible to failure (e.g. when fatigued or under great stress). Hence, making mistakes after years of perfecting a skill is nothing unusual and a normal human trait, which you should keep in mind to not get overly frustrated about yourself.
