Physical condition and an optimized diet are relevant to enhance performance and recovery. The diet composition and meal frequency of eleven elite wheelchair basketball players were estimated using a 3-day food-weighing diary in two months during the precompetitive-period. Performance was determined through a 20 m sprint test. The players consumed 4.2 ± 0.8 meals/day in May and 4.5 ± 0.9 meals/day in June, resulting in total energy intakes of 2492 ± 362 kcal/d and 2470 ± 497 kcal/d, respectively. The macronutrient distribution was 3.8 ± 1.3 g/kg carbohydrates, 1.7 ± 0.6 g/kg protein, and 36 ± 5% of energy derived from fat in May, and 4.2 ± 1.9 g/kg carbohydrates, 1.5 ± 0.5 g/kg protein and 32 ± 5% of energy derived from fat in June. The maximum velocity of the sprint test improved from 4.77 ± 0.31 m/s in May to 5.19 ± 0.23 m/s in June. Our results revealed carbohydrate intake below and fat intake above recommendations, but improvements of dietary patterns. Further nutritional advice is necessary to ensure health and performance improvements.

Power soccer (or powerchair football), the first competitive team sport for users of motorized wheelchairs, is receiving increased attention among people with disabilities, healthcare professionals, and academics. The present study provides a qualitative analysis of the experiences of 34 American power soccer athletes. Participant observation and in-depth interviews with 11 female and 23 male athletes were conducted between 2007 and 2013. Results indicate that involvement in power soccer provides participants with an increased sense of empowerment, acquisition of social capital, and psychosocial benefits, including a deep satisfaction of the desire to participate in competitive sports and an opportunity to be independent. Implications of these findings for improving the quality of life of people with physical disabilities and for future research are discussed.

Our purpose in this study was to document the criterion validity of the Fitbit Zip for measuring steps taken by youth with visual impairments (VI). A secondary purpose was to determine whether walking pace, mounting position, or relative position to the user’s mobility device impacted the criterion validity of the device. Fourteen adolescent-aged individuals (M age = 15.4; 13 male and 1 female) with VI participated in this study. Participants wore four Fitbit Zips at different mounting positions and completed two, 2-min walking trials while the lead investigator hand tallied steps. Measurement validity was analyzed using absolute percent error (APE), intraclass correlation coefficients estimated level of conformity, and paired samples t tests and Cohen’s d effect sizes assessed APE relative to mounting positions. Results supported the use of the Fitbit Zip during regular-paced walking; however, caution must be used during activities exceeding regular walking speeds, as devices consistently underestimated steps.

Effects of B-Active2 (Enjoy Being Physically Active by Walking Safely: A Leisure Education Program) on the risk of falls, stress, and well-being of a sample of 44 adults with ASD (ages M = 36.88; SD =7.31) were examined using a controlled experimental trial. Given the relationship between physical activity and stress reduction to individual well-being, B-Active2 was developed as a multidimensional program involving leisure education and walking designed to create an enjoyable context in which adults with ASD learn about and engage in physical activity. All participants were evaluated on balance, gait, well-being, and stress at baseline and at 1 month postintervention by a team of therapists blind to study objectives. There was a significant difference postintervention on balance, F(1, 40) = 55.63, p < .001, η2 = .58; gait, F(1, 40) = 23.58, p < .001, η 2 =.37; and well-being, F(1, 40) = 34.16, p < .001, η 2 = .47). No statistically significant effect was found for level of stress reduction, F(1, 40) = 0.27, n.s. Results of this study support the conclusion that B-Active2 is a viable leisure education program that promotes physical activity of adults with ASD and has positive effects on their well-being and risk of falls.

The aims of the current study were (a) to analyze the differences in game performances of sitting volleyball athletes representing the different types of disabilities and (b) to assess whether the seated position vertical reach is one of the crucial factors in the game performance level of sitting volleyball athletes. One hundred male athletes from various national teams participating in the European Championships in Sitting Volleyball (2009) took part in this study. The athletes were categorized according to type of disability and the results of the vertical reach in a seated position. Thirtysix games were analyzed using the Game Performance Sheet for Sitting Volleyball. Twenty-three game performance parameters were studied. In addition, the sum and effectiveness of attacks, blocks, block services, services, ball receiving, and defensive actions were calculated. The main results indicated significant differences between athletes with minimal disability and athletes with single amputations from above the knee in the level of defensive performances and the summation of defensive actions. There was also a significant difference between athletes in relation to their vertical reach during activity and attacking actions, blocks, and ball receiving. In addition, there were strong relationships between the players’ vertical reach scores and their activity and effectiveness in sitting volleyball. In conclusion, the accuracy of the World Organization Volleyball for Disabled classification systems for sitting volleyball players was confirmed. There is a strong relationship between players’ vertical reach and their effectiveness in sitting volleyball.

This paper demonstrates how a qualitative methodology can be used to gain novel insights into the demands of wheelchair racing and the impact of particular racing chair configurations on optimal sport performance via engagement with expert users (wheelchair racers, coaches, and manufacturers). We specifically explore how expert users understand how wheels, tires, and bearings impact sport performance and how they engage, implement, or reject evidence-based research pertaining to these components. We identify areas where participants perceive there to be an immediate need for more research especially pertaining to the ability to make individualized recommendations for athletes. The findings from this project speak to the value of a qualitative research design for capturing the embodied knowledge of expert users and also make suggestions for “next step” projects pertaining to wheels, tires, and bearings drawn directly from the comments of participants.
