The aim of this study was to assess the physical activity (PA) patterns of youth with intellectual disabilities (ID). PA was monitored for 7 days in 70 participants, 5–15 years old, using accelerometers. There were 32 participants included in the final analysis. Habitual PA and the number of continuous bouts accrued for a range of bout lengths (5–600 s) for light (LPA), moderate (MPA), and vigorous (VPA) PA were calculated. Multivariate analysis of covariance was used to assess differences in the number of continuous bouts by sex, age, and ID group and between week and weekend days. Participants exhibited short sporadic bursts of activity. The number of continuous bouts decreased as the intensity and duration increased. Few differences in PA patterns were reported by sex, ID group, and age group and between week and weekend days, possibly due to the generally low PA levels in this population.

This study compared the physical performance of Paralympic sprinters with visual impairments (PSVI) and their guides in jump and sprint tests. Ten PSVI and guides executed squat jumps (SJ), countermovement jumps (CMJ), horizontal quintuple right/left-leg jumps (QR/QL), decuple jumps (DEC), and 50-m-sprint tests. The guides were superior to the PSVI in SJ (35.9 ± 6.3 vs 45.6 ± 3.2 cm), CMJ (38.5 ± 6.2 vs 46.7 ± 4.0 cm), QR (9.2 ± 1.9 vs 12.7 ± 1.0 m), QL (9.4 ± 1.9 vs 13.1 ± 0.8 m), DEC (21.0 ± 3.3 vs. 27.2 ± 1.7 m), and 50-m sprints (8.4 ± 0.4 vs 7.6 ± 0.5 m/s). The average differences between the PSVI and guides in the sprint tests was 10%, range 1–24%. Therefore, substantial differences in sprinting speed (in favor of the guides) between the peers were observed. Coaches should develop strategies to train the guides to improve their muscle-power performance.

The purpose of this study was to develop a methodology to accurately analyze sprint performance of elite wheelchair basketball (WB) players in their own training context using a laser system and to analyze the velocity curve performed by the players regarding their functional classification and their playing position. Twelve WB players, from the Spanish men’s national team, took part in an oncourt 20-m-sprint test. BioLaserSport® was used to obtain time, mean velocities (Vm), maximum velocities (Vmax), and distances at 90%, 95%, and 98% of their Vmax. Vm and Vmax reached high values in Classes II and III and in the guard playing position. The protocol developed with the laser system makes it possible to obtain a precise velocity curve in short sprints and allows easy analysis of decisive kinematic performance variables in WB players, showing immediate feedback to coaches and players. The normalized data allow an interpretation of how much, where, and when Vmax occurs along the test.

The purpose of the study was to identify trends in research abstracts published in the books of abstracts of the European Congress of Adapted Physical Activityfrom 2004 to 2012. A documentary analysis of the contents of 459 abstracts was completed. Data were coded based on subcategories used in a previous study by Zhang, deLisle, and Chen (2006) and by Porretta and Sherrill (2005): number of authors, data source, sample size, type of disability, data analyses, type of study, and focus of study. Descriptive statistics calculated for each subcategory revealed an overall picture of the state and trends of scientific inquiry in adapted physicalactivity research in Europe.

The purpose of the study was to compare postural control in static standing in young adults with and without Down syndrome (DS), with eyes closed and eyesopen, before and after an 18-wk dance-based training program. The study included 11 young people with DS age 20.5 (1.3) yr and 11 without DS age 20.2 (2.0) yr.All parameters were recorded before and after the training program. Parameters related to center of pressure (COP; closed and open eyes) were recorded from aplatform with the participant in bipedal standing position during 30 s. The results suggest that young people with DS have worse COP control in both visual conditions (closed and open eyes) and are affected by visual information in a different way than their peers without DS. In the group of young adults with DS, thedance-based training program improved some parameters related to the use of visual input in controlling COP.

This study evaluated the effects of intense physical exercise on postural stability of children with cerebral palsy (CP). Center of pressure (CoP) was measured in 9 typically developing (TD) children and 8 with CP before and after a maximal aerobic shuttle-run test (SRT) using a single force plate. Anteroposterior and mediolateral sway velocities, sway area, and sway regularity were calculated from the CoP data and compared between pre- and postexercise levels and between groups. Children with CP demonstrated significantly higher pre-SRT CoP velocities than TD children in the sagittal (18.6 ± 7.6 vs. 6.75 1.78 m/s) and frontal planes (15.4 ± 5.3 vs. 8.04 ± 1.51 m/s). Post-SRT, CoP velocities significantly increased for children with CP in the sagittal plane (27.0 ± 1.2 m/s), with near-significant increases in the frontal plane (25.0 ± 1.5m/s). Similarly, children with CP evidenced larger sway areas than the TD children both pre- and postexercise. The diminished postural stability in children with CP after short but intense physical exercise may have important implications including increased risk of falls and injury.

Adults with Down syndrome (DS) tend to have low physical activity levels, which may relate to how they perceive participation in physical activities. The current study entailed interviews with 30 adults with DS (age 18–71 yr, 18 women) to examine how they perceived physical activity, exercise, and sport. Through qualitative analysis informed by grounded theory, the investigators found that adults with DS have positive perceptions of physical activity that center on enjoyment. Three facets of enjoyment were identified: interaction, achievement, and process. Interaction reflected enjoyment of social contact with others including relatives, peers, caregivers, and animals. Achievement involved enjoyment of achieving particular ends including accomplishment of tasks, material rewards, formation of athletic identities, and improvement of health. Process represented enjoyment from performing a particular activity itself. This multifaceted enjoyment expressed by adults with DS may facilitate physical activity and should be considered when developing programs to improve their well-being.

To analyze Latin American physical education (PE) teachers’ intentions toward teaching students with disabilities.
474 in-service PE teachers from 5 different Latin American countries.
Descriptive survey. Data were collected using a modified version of the Physical Educators’ Intention Toward Teaching Individuals With Disabilities Survey. Multiple-regression analysis showed significant differences in the attitudes of teachers by gender, the number of adapted-PE courses taken, and years of experience working with individuals with disabilities.
The predictor variables had a significant impact on the participants’ intentions toward teaching children with disabilities; however, the effects of these predictor variables differed between countries.
