Attitude of elite tennis coaches working with athletes with intellectual disabilities participating in Special Olympics.

Background: There is a paucity of research regarding the attitudes of coaches towards training athletes with intellectual disabilities (ID). This is particularly evident for coaches working with athletes with ID that are competing in the innovative Special Olympics (SO) Unified Sports programme. Research on the inclusive impact of sport plays a significant role, not only in sports development but also in the training of sports professionals and coaches, as a sufficient amount of special coaching experience is required to achieve inclusion.

Physical activity and sedentary behaviour among children and adolescents with intellectual disabilities during the COVID-19 lockdown in China.

Background: In the wake of the COVID-19 pandemic, preliminary research has reported a significant decline in physical activity (PA) and an increase in sedentary behaviour (SB) among typically developed children and adolescents. Limited research has looked at the current situation of PA and SB during this pandemic among children and adolescents with intellectual disabilities (ID). This study investigated the situations about PA and SB among school-aged children and adolescents with ID on China's mainland during the COVID-19 outbreak.

Prevalence of overweight and obesity in children and adolescents with intellectual disabilities in China.

Background: Overweight and obesity in children and adolescents has become a worldwide epidemic. There are several studies that have concentrated on the prevalence rate of children and adolescents with intellectual disabilities (ID), whereas data on such a population on the mainland of China remain unclear. The purpose of this study was to investigate the prevalence rate of overweight and obesity among school-aged children and adolescents with ID on China's mainland.

Eurofit special: European fitness battery score variation among individuals with intellectual disabilities.

The Eurofit Special Test is a battery of motor fitness tests resulting from a 10-year project of the Committee of Experts for Sports Research and is comprised of strength, speed, flexibility, and balance. The purpose of this study was to investigate whether the Eurofit Special was able to distinguish variations in functioning among individuals with intellectual disabilities. Significant differences were found in long jump flexibility 25-m dash, medicine ball throw, balance walk, sit ups in 30-s.

Augmented feedback for enhanced skill acquisition in individuals with traumatic brain injury.

Coincident timing by individuals who exhibit traumatic brain injury was measured under conditions of no knowledge of results (no KR; n = 12), KR on every trial (n = 14), summary KR (n = 13), and average KR (n = 12). Following acquisition trials, groups performed immediate and longer retention trials without KR. Absolute constant error and variable error, analyzed in separate repeated-measures analyses of variance, indicated that during acquisition trials subjects receiving KR on every trial were the most accurate and the most consistent in their responses; however, subjects in groups receiving summary and average KR were the most accurate during immediate retention, with the group receiving summary KR being the most accurate during longer retention.

Coincident timing by nondisabled, mentally retarded, and traumatic brain-injured individuals under varying target-exposure conditions.

Coincident timing by 15 nondisabled individuals, 15 mentally retarded and 15 traumatically brain injured was measured under varying target-exposure conditions. Absolute constant error, constant error, and variable error were analyzed in separate repeated-measures analyses of variance for early performance (first block of practice), late performance (last block of practice), and retention (last block of retention). Subjects with mental retardation displayed the least accurate and most variable coincident-timing responses.

Intratester reliability of the Nicholas Manual Muscle Tester on individuals with intellectual disabilities by a tester having minimal experience.

The purpose of this investigation was to determine the intratester reliability of measurements obtained with the Nicholas Manual Muscle Tester (NMMT) by a tester having minimal experience on individuals with intellectual disabilities. Seventeen individuals classified as moderately mentally retarded between the ages of 14 and 24 (mean = 18.65) were evaluated with the NMMT using a test-retest reliability procedure after a familiarization session.

Magnitude and reliability of measurements of muscle strength across trials for individuals with mental retardation.

The purpose of this investigation was to examine the magnitude and reliability of strength measures on the Nicholas Manual Muscle Tester for individuals with mental retardation. 17 subjects were given six trials with the dominant and nondominant flexor and extensor muscle groups. No significant differences were found between dominant and nondominant muscle groups by side or by muscle group.
