Psychometric properties of two systematic observation tools, the System for Observing Fitness Instruction Time (SOFIT) and the Children's Activity Rating Scale (CARS), were examined for use with individuals with mental retardation (MR). Eleven children with MR were videotaped while participating in gym-based physical activity. Accelerometer data were collected and synchronized...
Sleep is an active process that affects an individual's daily functioning and physical and mental health. It is also beneficial for an individual's overall health and well being. Children with autism often have difficulty sleeping. One common complaint from parents of children with autism is that these children lack sufficient...
The ability to establish and maintain balance is claimed to be an important prerequisite of movement tasks. However, despite this general belief, there is limited empirical evidence to support the contribution of balance in motor skill performance. Furthermore, psychometric properties of using a computerized force platform to assess balance ability...
Physical activity is increasingly recognized as a maj or component contributing to the promotion of a healthy lifestyle. Evidence exists that a physically active behavior is carried over from childhood to adolescents and possibly to adulthood. Limited research about the physical activity behavior of students with visual impairment is available,...
Generalizability theory was used to examine sources of variability in daily physical activity levels of secondary students with and without developmental disabilities (DD), and to determine minimum number of days required for monitoring their typical physical activity levels. Sixteen participants with DD (M = 16.7 years, SD = 2.7 years),...
School Physical Education programs provide key opportunities to promote lifetime physical activity (PA) to students, while at the same time students can build a sense of enjoyment. The purpose of this study first sought to determine the effects of varying instructional approaches on the enjoyment and PA levels of students...
The methods to educate students with disabilities in physical education contexts vary greatly due to their unique characteristics and special needs, requiring different teaching methods on an individual basis. In order to improve educational outcomes for students with disabilities in physical education settings, teachers should employ evidence-based practice (EBP). However,...
It has been demonstrated that walking is the most common form of physical activity for adults with intellectual disabilities, including Down syndrome (DS). The pedometer is common measurement tool to quantify steps walked, yet there is little evidence of the psychometric properties for individuals with intellectual disabilities, particularly DS. Thus,...
The low physical activity levels of children today are a cause for serious concern. When examining certain populations of children, such as children with Autism Spectrum Disorder (ASD), there is a possibility of even lower overall physical activity levels. However, when exploring the current literature examining the physical activity levels...

Physical education is important to promote physical activity of adolescents with and without disabilities, but many adolescents are not active during physical education classes. Innovative instructional strategies are imperative to change this phenomenon, but it will be challenging to develop effective instructional strategies without thorough understanding of students' physical activity...
