Masa muscular, fuerza isométrica y dinámica en las extremidades inferiores de niños y adolescentes con síndrome de Down

Resum

Generally it has been observed that population with Down syndrome (DS) has lower levels of muscular strength compared with others without DS. It is also known a deficit between muscular mass between adults with and without DS. However, there are no studies until the date which evaluated muscular mass in paediatric populations. Our study pretends to show whether also in earlier ages it does exist a deficit in the muscular mass and also to relate both values. Children and adolescents with and without DS (15±3 y 14±3 years respectively) from the study had similar values of muscular mass adjusted by height and puberal status, but DS group obtained lower values in all strength parameters. In addition, DS group also performed less kilograms of strength by kilogram of muscular mass. Some physiological or transmission impairment could explain this lack of strength as it known that there are not deficit in the muscular mass. Specific and adapted for this population training programs should be promoted to check whether an enhancement in their muscular strength is possible.
