Background: Athletes with intellectual disability represent a unique population who experiences the contrasting effects of cognitive deficits and benefits of sports on balance. This study investigated the combined impact of intellectual disability and sport practice on balance. Method: Center-of-pressure excursion in bipedal stance of 2 disability (with and without intellectual disability) × 2 sport practice (athlete and novice) participant groups was measured in several balance conditions. Results: Sport practice exerted no significant effect on any of the center-of-pressure measures used. In contrast, intellectual disability's effects on balance, which were most apparent in challenging balance conditions, were significant (p < 0.05) and had large effect sizes ([partial eta-squared] > 0.13). Conclusion: The negative effects of cognitive deficits on the balance of young adults with intellectual disability underscore the need for effective interventions. Although findings did not support sports' balance-remediating potential, the value of sport participation for individuals with intellectual disability cannot be fully dismissed just yet.

Although motor problems are highly prevalent in children with autism spectrum disorder (ASD), they remain underdiagnosed. Questionnaire-based screening for motor problems could optimize current clinical practice. This study aimed to examine the psychometric properties of the developmental coordination disorder questionnaire (DCDQ) to screen for co-occurring motor problems in individuals with ASD (n = 115; aged 5-15 years). Results indicated an excellent internal consistency; concurrent and discriminant validity with the Movement Assessment Battery for Children, second edition. Sensitivity was excellent, but specificity was lower. The positive and negative predictive values indicate that the DCDQ can be used to detect motor problems in children with ASD and can exclude the presence of developmental coordination disorder.

This study explored the association between intelligence and motor skills in children with ASD after controlling for Attention Deficit and Hyperactivity Disorder (ADHD) and the associations between motor impairment and intellectual disability (ID) in this population. In total, 120 children with ASD (3-16 years; 81.7% boys) completed a standardized intelligence test, the Movement Assessment Battery for Children and Beery-Buktenica Developmental Test of Visual-Motor Integration. Variance in performance IQ was associated with 20.8% of the variance in motor skills while significant associations were found between comorbid ID and motor impairment ([phi] = 0.304). Manual Dexterity and Balance are moderately influenced by performance IQ in children with ASD. Furthermore, presence of ID is also moderately associated with motor impairment in this population.

Background: This meta-analysis aims to: (i) describe the pooled prevalence of diabetes in people with intellectual disabilities, (ii) investigate the association with demographic, clinical and treatment-related factors and (iii) compare the prevalence versus age- and gender-matched general population controls. Methods: PubMed, Embase and CINAHL were searched until 01 May 2021. Random effects meta-analysis and an odds ratio analysis were conducted to compare rates with controls. Results: The trim- and fill-adjusted pooled diabetes prevalence amongst 55,548 individuals with intellectual disabilities (N studies = 33) was 8.5% (95% CI = 7.2%-10.0%). The trim- and fill-adjusted odds for diabetes was 2.46 times higher (95% CI = 1.89-3.21) (n = 42,684) versus controls (n = 4,177,550). Older age (R[superscript 2] = 0.83, p < 0.001), smoking (R[superscript 2] = 0.30, p = 0.009) and co-morbid depression (R[superscript 2] = 0.18, p = 0.04), anxiety (R[superscript 2] = 0.97, p < 0.001), and hypertension (R[superscript 2] = 0.29, p < 0.001) were associated with higher diabetes prevalence rates. Conclusions: Our findings demonstrate that people with intellectual disabilities are at an increased risk of diabetes, and therefore routine screening and multidisciplinary management of diabetes is needed.

This systematic review synthesized the literature on digital health interventions for the promotion of physical activity (PA) among people with intellectual disabilities and/or autism. From an initial screening of 553 records, 10 studies underwent full-text review. Data were extracted relating to study, intervention, and sample characteristics and PA-related findings. Methodological quality was evaluated using the Crowe Critical Appraisal Tool. There were mixed findings pertaining to the effectiveness of digital health interventions for promoting PA among these populations. Positive results were reported for three of five active-video-game interventions, two of three social-media-based interventions, and one of two e-learning/multicomponent interventions. Digital health interventions can potentially be effective for promoting PA among people with intellectual disabilities and/or autism. However, the large variation in the samples and intervention types and a reliance on pre- and quasi-experimental research designs suggest that inferences should be made with caution and additional research is needed.

Background: High anxiety levels are common in people with intellectual disabilities (ID) and anxiety can affect sport performance, but sport competitive anxiety profiles in athletes with ID are unknown. Methods: A total of 303 athletes; 116 with ID (33% female, M age = 22.64, SD = 3.94), and 187 without ID (54% female, M age = 21.81, SD = 3.23), completed the modified questionnaire Sport Anxiety Scale-2-FLemish-ID (SAS-2-FL-ID). Results: The SAS-2-FL-ID was a valid tool to use in a population of athletes with ID. They had higher trait anxiety (9.36 ± 2.62) than peers without ID (7.58 ± 2.44), F = 26.95, p<0.001. With respect to sport anxiety, they only scored higher on the "concentration disruption" subscale. Their overall level of competitive anxiety across all subscales (24.14 ± 7.73) was significantly lower compared to athletes without ID (26.51 ± 7.49), F = 27.10, p<0.001. Conclusion: On the sporting field, athletes with ID worry less and feel less somatic anxiety compared to athletes without ID.

The aim of this study was to investigate the role of age and intellectual impairment (II) in decision-making in basketball. The current study investigated differences in decision making between equally well-trained adult basketball male players with intellectual impairment (players with II) (n = 93), adults without II (senior) (n = 44) and youth basketball players (under-14, n = 31; under-16, n = 25; under-18, n = 30). A computer test was developed composed by 20 photographs displaying various basketball game-situations, and participants had to decide as fast as possible what the player in ball possession should do: dribble, pass or shoot. Decision time and accuracy were recorded for every situation. Players with II had slower decision time (3.8 ± 1.8 s vs. 1.5 ± 0.5 s, p < 0.001) and less decision-making accuracy (15.7 ± 2.8 correct decisions vs. 17.9 ± 1.2 correct decisions, p < 0.001) compared to senior players without II. Discriminant analysis with speed and accuracy as independent variables classified 91.2% (CCA = 0.769) of the players correctly into their group: players with II or players without II. A Spearman correlation revealed that age correlated significantly (p < 0.001) with the number of correct decisions (rs = 0.269) and mean decision time (rs = -0.331). Our findings support that decision making in basketball develops with age and experience, but is significantly deteriorated in experienced adult players who have II. Decision-making should be considered as an important eligibility criterion to participate in competitive basketball events for male players with II. [ABSTRACT FROM AUTHOR]

Purpose: Ingestion of sildenafil citrate has performance-enhancing effects at high altitudes above 3800 m in able-bodied individuals. It is unknown whether it can improve the performance of athletes with spinal cord injury (SCI) at moderate altitudes (<2200 m), relevant to Paralympic competitions. As most men with SCI suffer from erectile dysfunction of neurologic origin and use sildenafil on a regular basis, it seems important to study the impact of sildenafil on exercise capacity. The outcome of this study is also relevant to the antidoping community. Methods: Twenty-seven healthy male wheelchair athletes with a motor-complete SCI participated in this prospective double-blind, randomized, placebo-controlled study. The participants performed arm cranking exercise to exhaustion at sea level and moderate altitude (2200 m) after ingestion of 50 mg sildenafil citrate or a placebo. Peak power output, peak oxygen uptake, peak heart rate, rating of perceived exertion, oxygen saturation, and lactate concentrations at exhaustion were measured. Results: Friedman analysis showed that peak power output at sea level was significantly higher (P =.004) under placebo treatment (median [minimum; maximum]: 120 W [35; 170]) compared with sildenafil (115 W [40; 165]). Blood oxygen saturation under sildenafil treatment at sea level (98% [81; 100]) was significantly higher (P =.006) compared with sildenafil treatment at moderate altitude (94% [85; 100]). All other parameters revealed no impact of sildenafil or altitude. Conclusions: In this study, the ingestion of sildenafil citrate in athletes with SCI demonstrated no positive effects on peak arm-cranking-exercise capacity compared with placebo either at sea level or at moderate altitude.

In this study the ability of elite table tennis players with intellectual disability (ID) to adapt their service/return to specific ball spin characteristics was investigated. This was done by examining the performance of 39 players with ID and a reference group of 8 players without ID on a standardized table tennis specific test battery. The battery included 16 sets of 15 identical serves that had to be returned to a fixed target, and two additional tests measuring reaction time and upper limb speed. A 2 x 4 ANOVA (with group and type of spin as independent variables) with repeated measurements (15 consecutive returns) supported the hypothesis that elite table tennis players with ID were significantly less proficient than their counterparts without ID, but both groups demonstrated a comparable progression in learning. Spearman correlation coefficients indicated a positive relationship between accuracy of return and upper limb speed (rho = 0.42: p less than 0.05) and reaction time (rho = 0.41: p less than 0.05), showing that these generic factors are useful in partially explaining skill variations in specific sports.

Evidence-based classification systems in Paralympic sport require knowledge of the underlying effect of impairment in a specific sport. This study investigated the relationship between cognition and tactical proficiency in 88 well-trained table tennis players with intellectual disability (ID; 29 women, 59 men, M ± SD IQ 59.9 ± 9.6). Data were collected at 3 competitions sanctioned by the International Federation for Para-Athletes with Intellectual Disabilities (INAS). A generic cognitive test consisting of 8 neuropsychological subtests was used to assess cognitive abilities relevant to sport (reaction time, processing speed, and decision speed; spatial visualization; fluid reasoning; memory; executive functioning; and visual processing). The backward stepwise-regression analysis model revealed that 18% of the variance in tactical proficiency was attributed to spatial visualization and simple reaction time. Applications of these findings resulted in an evidence-based classification system that led to the reinclusion of athletes with ID in Paralympic table tennis and provide the basis for future research in this important area.
