Selected factors correlated to athletic performance in adults with mental retardation

The aims of this study were to assess the contribution of selected factors to the athletic performance in adults with mental retardation (MR) and to analyze the correlation of each factor with subjects' MR levels. Twentynine trained athletes with MR aged 20-45 years were recruited. The fundamental factors included anthropometric measurements, flexibility, muscular strength and endurance, explosive leg power, cardiovascular endurance, and motor coordination. The athletic performances were as follows: 60 m, 300 m, 400 m in walking, standing long jump, and vortex throw (Level I) or 100-m run, shot put, and long jump (Level II). Motor coordination and body weight had significant contributions to 60 m (p < 0.01) and the %body fat had significant contribution to 300 m and 100 m (p < 0.05). The explosive leg power had significant contribution to vortex throw and standing long jump (p < 0.05). The upper-body strength and muscular endurance had significant contribution in shot put (p < 0.05). The body weight had significant contribution in long jump (p < 0.05). MR level was positively correlated to motor coordination (p < 0.05) and negatively to abdominal muscular strength and endurance (p < 0.05). In conclusion, the results showed the possibility to determine the contributions of selected factors to the athletic performance. This should be addressed in athletics training to help athletes with MR to perform successfully in their competitions. © 2010 National Strength and Conditioning Association.
