The purpose of this study was to investigate the effects of bowling exercises on gait pattern and posture students with mental retardation and social interaction with students without disabilities. The videography method was used to obtain kinematical variables of gait pattern for pre & post tests of bowling exercises. The posture of students with mental retardation and interaction with students without disabilities were recorded onto video tapes. Analyzing the recorded data from all experiments led to the following conclusions: irregular gait pattern and posture of the students with mental retardation can be corrected or improved substantially through bowling exercises. And the inclusive exercises program with students without disabilities can show the model appropriate behavior, encourage social interaction, and promote positive self-esteem to the students with mental retardation.
