Muscle memory in athletes: Exploring the neuromuscular adaptations and long-term performance benefits

Dear Editor, The human body tissues consist of body cells that have the ability to create movement and are called muscles. Muscles play a key role in moving body parts and the body as a whole to react to any incident. This can be contracted or relaxed, and by doing so, it moves a certain part of the body.[1] Thus, to perform the move fluently, the direction of each subsequent move must be remembered. Indeed, it all starts in the brain, where the sensory neurons detect external stimuli such as sound, light, and pressure. These signals are delivered to the central nervous system through sensory neurons. There, the signal is processed, and the response instructions are determined. Motor neurons carry the instructions to the muscles of the body part, the instructions are sent to.[2] Then motor neurons stimulate muscles to contract or relax to make the appropriate responses. Obviously, there is a time gap between detecting the stimuli and the response to the stimuli. In this case, reaction speed is essential so that the body can respond without conscious thought much.[3] Since the prefrontal cortex of the human brain, which is the area responsible for thought, is where all of the process takes place, it is time-consuming.[4] However, the motor learning process modifies a person’s motor neurons when they repeatedly respond to the same stimuli. The basal ganglia in the brain become active and respond in a self-sufficient manner without requiring much thought, thus achieving muscle memory at this point.[5-7] In sports, reaction speed is crucial for success where players’ actions and reactions are faster in every game situation. For instance, an attacking football player with fast dribbling can break the defense line quickly, while a defender with good reaction timing can prevent it. Therefore, faster judgment and delivery are essential in football, making it an essential sport. On the other hand, during training, athletes practice specific movements, such as a tennis serve, a golf swing, or a basketball shot and each of these repetitions strengthens the neural networks that control these movements, thereby improving brain–body synchronization. Altogether, players prefer to practice the same thing over and over, and by doing that, muscle memory is achieved. In this scenario, players practiced multiple times, and in the backstage basal ganglia, they processed these stimuli autonomously, which feels like there is no need for active thinking.[5] However, after achieving muscle memory for particular scenarios, players need less time to execute the movement in contrast to the time needed before muscle memory is achieved. Players no longer need to think consciously about the solution for the situation or the reaction to the action. It feels like muscles related to the reaction task or the solution already know the task and execute it properly without any irritation to the brain. Hence, these courses of action or reaction take less time than active thinking when they face something for the first time. In competitive sports are highly intensified and during a match, sportspersons generally do not have enough time or mental state to think about every situation and every move of their teammates or opposition players individually. Rather, it is their muscle memory that drives them mostly toward their actions and reactions with faster processing and execution.[6,7] Hence, it is obvious that, in a tight space or as a reaction to any sudden move from an opponent, there is nothing but muscle memory. In the sports field, there are dynamic situations, situations a player has never faced before. A player has to process those stimuli and react in the fastest time possible. Nevertheless, most of the time a player has to do the routine work accurately to keep consistency and make the game quick. Interestingly, elite players do not do magical stuff every time; they do the common stuff consistently. Hence, the player who has developed muscle memory well is the most consistent player. The team that has more consistent players has a consistent performance in every game, and the teams with consistency win the title every year. The idea of muscle memory is also noteworthy when athletes return to their sport after a period of inactivity, such as injury or an off-season break. Once a skill is encoded in muscle memory, it can be reactivated quicker compared to learning it from scratch. This means that an athlete who has undergone proper training and later takes a break can regain their previous skill level more rapidly, as their nervous system still retains the motor patterns they learned through thousands of repetitions. In spite of that the impact of muscle memory is not always an unmixed blessing. If players develop muscle memory in an inappropriate manner, such as without the proper guidance of a coach or trainer, it may be achieved in a bad way, and as it is a well-achieved neurological change, players may find it very difficult or sometimes impossible to get rid of it totally. Hence, it may lead to an injury-prone playing style, which may lead to a short and ungratified career. In these circumstances also, muscle memory has an impact on sports performance, but in a negative manner.[5] Therefore, it can said that if an athlete consistently practices a flawed technique, that incorrect movement pattern will also become ingrained, making it challenging to unlearn. Thus, correct form and proper coaching are vital to ensure that athletes develop beneficial muscle memory rather than habits that could lead to inefficiency or injury. Given that, each muscle responds to external stimuli and that muscle memory is acquired from a neurological standpoint, it seems logical that muscle memory and sports performance are linked on all counts and have been scientifically verified. It is not simply about muscles maintaining memory, but rather a mix of neurological and muscular changes that contribute to the development of autonomous motor skills. Indeed, muscle memory is based on procedural memory, a type of long-term memory that allows people to accomplish activities without thinking about it. The concept of muscle memory underscores the importance of consistent training in building a robust foundation for athletic performance, as well as its role in facilitating recovery and retraining after injury or downtime. In summary, muscle memory in sports is the process of encoding motor skills through repetition, leading to effortless, automatic execution of movements. Financial support and sponsorship Nil.
