Lateralization in Sport.

Posted by on / 10 Comments

By observing the organization of our body we can see that there is a certain symmetry, where both members and internal organs are duplicated.

Even our brain has two hemispheres, which have similar appearance but are not identical.

Each one is specialized in performing certain functions, while the left hemisphere is related to speech, analytical and logical thinking, the right hemisphere is associated to emotions, holistic thinking and creativity.

Moreover, if we refer to motor activity, each hemisphere controls the contralateral half of the body, meaning that the left hemisphere controls the movements made by the right half of the body and vice versa.

Laterality is the functional domain of one side of the body over the other, it manifests itself in the preference to selectively use of a certain member (hand, foot, eye, ear) to perform specific activities.

This predilection is the result of a process of learning and practice during childhood (lateralization), it is evidenced as a tendency at the age of 4 and stabilized at the age of 6, when the child becomes aware of his own left and right (on himself).

It is not until the age of 8 that the child can recognize the left and right of others.

This progressive affirmation of laterality (lateralization) enables the child to orient in the space which contributes to his/her motor evolution (Bilbao, Oña, 2000).

This laterality not only refers to the use of a specific hand, but also the preference of an eye, one shoulder, a waist, a leg or a foot.

The choice of one side over the other in each of them determines that different people, facing the same situation, move their body differently.

Obviously this affects the technique developed by athletes and also the most suitable training for everyone.

There is a major proportion of dexterous (87%) in the world population.

Usually the child manifests a preference for one hand during lateralization, but there are some children who are skilled with both hands and they can exchange their dominant hand depending on the day. In these cases where there is no preference, the coach can guide the lateralization towards the skillful hand.

Studies show that there is a different speed of response depending on the eye used. The movements produced as a result of stimulation of the dominant eye have shorter reaction than those evoked by the nondominant eye (Minucci, Connors, 1964).

They also found that the effect of the dominant eye varied if the person was left-handed or right-handed and it also varied with the location in space of the stimulus which the person should react to (Chaumillon, R., Blouin, J., Guillaume, A., 2014).

The relationships between eye-hand dominance and eye-foot dominance have a key role in motor skills and sports performance.

The knowledge of laterality that the athlete has allows us a better understanding of his/her technique and the development of a customized training which enhance his/her nondominant hand (Dorochenko, Paul).


Do you know your laterality?

Do you need exercises that help you to identify it?

Do you have athletes in lateralization process?

    WONDERFUL Post.thanks for share..more wait .. !There are certainly a lot of details like that to take into consideration. That is a great point to bring up. I offer the thoughts above as general inspiration but clearly there are questions like the one you bring up where the most important thing will be working in honest good faith. I don?t know if best practices have emerged around things like that, but I am sure that your job is identified as a fair game clearly. Both boys and girls feel the impact of just a moment’s pleasure, for the rest of their lives.

      Thanks for your comment! It is deeply inspiring to me to know that my work is useful.

        No problem at all. I was senrchiag for a few links to several publications written by Dr. Lorimer Moseley on the subject of laterality. Several other researchers have explored the subject as well, all readily available via a google search. I am glad that you found the answers you were looking for, and am always happy to answer any other questions that you may have. Thanks for reading!

      Thanks for your comment! I´m working in a tennis academy (Elite Tennis Academy) where we put in practice this knowledge. We have very good results and our sessions are original, innovative.
