The purpose of this study was to develop a compendium of wheelchair-related physical activities. To accomplish this, we conducted a systematic review of the published energy costs of activities performed by individuals who use wheelchairs. A total of 266 studies were identified by a literature search using relevant keywords. Inclusion criteria were studies utilizing individuals who routinely use a manual wheelchair, indirect calorimetry as the criterion measurement, energy expenditure expressed as METs or VO2, and physical activities typical of wheelchair users. Eleven studies met the inclusion criteria. A total of 63 different wheelchair activities were identified with energy expenditure values ranging from 0.8 to 12.5 kcal·kg-1·hr-1. The energy requirements for some activities differed between individuals who use wheelchairs and those who do not. The compendium of wheelchair-related activities can be used to enhance scoring of physical activity surveys and to promote the benefits of activity in this population.

The purpose of this study was to examine the effects of visual supports on the performance of the Test of Gross Motor Development (TGMD-2) for children with autism spectrum disorder (ASD). Participants (N = 22) performed the TGMD-2 under three different protocols (traditional protocol, picture task card protocol, and picture activity schedule protocol). Gross motor quotient scores on the TGMD-2 were measured and statistically analyzed using a within-subjects repeated-measures ANOVA. Results indicated statistically significant differences between protocols, while post hoc tests indicated that the picture task card condition produced significantly higher gross motor quotient scores than the traditional protocol and the picture activity schedule. The results suggest that more accurate gross motor quotient scores on the TGMD-2 by children with ASD can be elicited using the picture task card protocol.

Reduced respiratory muscle strength in individuals with Down syndrome (DS) may affect speech respiratory variables such as maximum phonation duration (MPD), initiation volume, and expired mean airflow. Researchers randomly assigned adolescents with DS (N = 28) to either 12 weeks of swim training (DS-ST) or a control group (DS-NT). Repeated measures MANOVA demonstrated a significant increase in MPD for DS-ST participants from pretest to posttest, t(11) = –3.44, p = 0.006, that was not maintained at follow-up, t(11) = 6.680, p < .001. No significant change was observed for DS-NT participants across time, F(2, 11) = 4.20, p = 0.044. The lack of long-term change in DS-ST participants may be related to the relatively short training period.

The purpose of this study was to describe running economy, soccer specific endurance, and selected kinematic running criteria in soccer players with cerebral palsy (SPCP) and to compare them with values of position-matched players without CP. Fourteen international, male soccer players with cerebral palsy completed the “Yo-Yo” intermittent recovery run level 1 (IRL-1) test to assess soccer-specific endurance and a submaximal running test on a treadmill to determine running economy. The mean IRL-1 distance covered by the SPCP of the Irish CP team was found to be 43–50% below the mean distance attained by position-matched soccer players without disability, while running economy was found to be within the range of that reported for able-bodied athletes. No relationship could be found between the level of CP-ISRA classification and soccer-specific endurance or running economy in this group of elite level SPCP. Though small in number, these data support a further examination of the relationship between CP classification and sport-specific performance.

The inclusion of able-bodied athletes within disability sport, a phenomenon known as reverse integration, has sparked significant debate within adapted physical activity. Although researchers and practitioners have taken up positions for or against reverse integration, there is a lack of supporting research on the experiences of athletes who already play in such settings. In this study, we explore how competitive female athletes who have a disability experience reverse integration in Canadian wheelchair basketball. Athletic identity was used as the initial conceptual framework to guide semistructured interviews with nine participants. The results suggest that participation in this context contributed to positive athletic identities. Interviews also pointed to the unexpected theme of “what’s the difference?” that this sporting context provided a space for the questioning and creative negotiation of the categories of disability and able-bodiedness. Methodologically, this paper also explores the possibilities and challenges of inter- worldview and insider-outsider research collaboration.

This study examined interrelationships among athletic identity, sport participation, and psychological adjustment in a sample of people with spinal cord injury (SCI). Participants (N = 1,034) completed measures of athletic identity, life satisfaction, anxiety, depression, and demographic and sport participation variables. Current amount of weekly sport participation was positively related to athletic identity when statistically controlling for age, gender, and pre-SCI amount of weekly sport participation. Being able to practice one’s favorite sport after SCI was associated with higher levels of athletic identity and better psychological adjustment. Team sport participants reported experiencing better psychological adjustment than individual sport participants did. The findings suggest that social factors are important in the link between sport participation and psychological adjustment in people with SCI.
