The purpose of this study was to compare physical fitness levels of trained runners with mild mental retardation (MMR) (7 males and 2 females, age = 28.7 ± 7.4 years, weight = 67.0 ± 11.7 kg) and those without (7 males and 2 females, age = 29.1 ± 7.5, weight = 68.7 ± 8.8 kg). Paired t tests revealed no differences between runners with and without MMR on measures of V̇O2peak (56.3 ± 9.1 vs. 57.7 ± 4.1 ml · kg-1 · min-1), percent body fat (16.6 ± 8.4 vs. 16.6 ± 3.1), and lower back/hamstring flexibility (33.1 ± 10.9 vs. 28.6 ± 10.1 cm). Knee flexion (KF) and extension (KE) strength were significantly greater in runners without MMR compared to those with MMR (KF peak torque = 65.7 ±7.9 vs. 48.7 ± 15.7 ft/lb; KE peak torque = 138.5 ± 17.7 vs. 104.4 ± 29.9 ft/lb). It was concluded that trained runners with MMR can achieve high levels of physical fitness comparable to individuals without MMR.
