چکیده
This study evaluated the relationship between leg strength and endurance run performance, independent of aerobic capacity (\;TOzp,,), body size, and gender, in children and adolescents with mild or moderate mental retardation. Twenty-six individuals (15 boys and 1 I girls) volunteered and underwent tests of YOzp,,, isokinetic leg strength, and endurance run performance (600-yard rudwalk and 20-m shuttle run). Results showed that leg strength was significantly related to both types of run performance; however, when controlling for \;T02pc,, body size, and gender, leg strength was a more significant contributor to the 600-yard ~ d w a l k than to 20-m shuttle run performance. Gender did not influence these relationships. These data suggest that leg strength has a significant influence on endurance run performance in children and adolescents with mild or moderate mental retardation.
