In recent years, there has been an increased interest in accurately measuring physical activity levels with accelerometers. Two distinct approaches have been used to estimate physical activity levels with accelerometers are vertical axis activity counts and vector magnitude (VM). Although previous studies evaluated these two distinct approaches for individuals without...
The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...
Physical activity is important for health. However, there is a lack of literature related to the physical activity levels of adults living in urban villagers, which is a vulnerable population in China. The aim of this study is to compare the physical activity and sedentary behavior engagements between urban villagers...
The purpose of this study was to explore the current levels of physical activity among youth with disabilities using meta-analysis. The search identified 11 publications including 729 participants (age 4-20 yr). The overall effect size for 11 studies was Hedges g = 0.60 (SE = 0.18, 95% confidence interval [CI]...
Cellulose nanocrystals (CNCs) are extremely abundant, biodegradable and light weight nanoparticles that have the potential to contribute in many fields including packaging, construction, solar cells and automotive. With the increasing interest in nanotechnology and nanocomposites, CNCs could provide a renewable, optically transparent and strong alternative to other nano-scale reinforcement phases....
Nanotechnology products have long since made their way to markets around the world increasing the concerns about whether nanomaterials pose a risk to our environment or health. It has been suggested that engineered nanomaterial (ENM) with broad applications and rapid commercialization need better risk assessment and regulation. However, the refinement...
The levels of cooperation in efforts towards transboundary water management in the Aral Sea basin have ranged from high to low over the past few decades, due in part to diverse purposes for water use in the region. Two important and often conflicting uses are agriculture and hydropower, which tend...
There is an emerging interest in developing wearable electronics as a platform, which
provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced
photonics and optoelectronic...
Silicon carbide (SiC) and aluminum nitride (AlN) exhibit a combination of thermal and mechanical properties that are relevant to applications in electronics, aerospace, defense and automotive industries. However, the successful translation of these properties into final applications lies in the net-shaping of these ceramics into fully dense microstructures. Increasing the...
The purpose of this study was to explore the relationship between physical activity level and motor skill proficiency in school-aged children ages 9-18 with developmental disabilities. Physical activity level was assessed using Actigraph GT3X+ accelerometers, which participants wore for all hours of the day for seven days. Motor skill proficiency...
Many children with developmental disabilities are not engaging in the recommended amount of daily physical activity (Pan, 2008; Shields, Dodd, & Abblitt, 2009; Whitt-Glover et al., 2006), which can lead to additional health disparities and decreased quality of life for children in this population (Field & Jette, 2007). The relationship...
Background. Autism spectrum disorder (ASD) is characterized by impairments in social-communicative deficits and restricted and repetitive behaviors, interests, or activities (APA, 2013). While current estimates suggest 1 in 68 children are diagnosed with ASD, more alarming statistics indicate 1 in 50 school-aged children live with the disorder (Blumberg, Bramlett, Kogan,...
Children with autism spectrum disorder (ASD) have been reported to have motor skill delays and deficits. However, there have been challenges to these findings on whether these deficits are due to lack of movement skills or inaccurate assessment methods. Due to relative strengths in processing visual stimuli as opposed to...
Background: Mastery of fundamental motor skills (FMS) in childhood is proposed to facilitate participation in physical activity (PA) opportunities, through context-specific application of FMS (Clarke & Metclafe, 2002; Stodden et al., 2008). Children with disabilities
impacting motor skill development thus are at greater risk for low PA participation. Evidence indicates...
Early childhood is a crucial time for the holistic development of a child’s social, emotional, cognitive, and physical needs to build a solid and broad foundation for lifelong wellbeing and learning (Irwin et al., 2007). During this critical period, there is an increased demand for motor skills and executive function...
In 2022, the Report Card on Physical Activity for Children and Youth noted only 24% of children ages 6 to 17 years achieved the recommended 60 minutes of physical activity daily, with a drop in physical activity as children age (Barriss, 2022). More importantly, children with disabilities have been found...
