Can Special Olympics coaches accurately report on the motor competence of children with intellectual disabilities?

BACKGROUND: Motor competence is the ability to perform goal directed human movements in a co-ordinated, accurate and error free manner. The aim of this study was to compare the accuracy of coaches' perceptions of children's motor competence with their actual motor competence. METHOD: This study examined the motor competence of children with intellectual disabilities (n = 100) and coaches' perceptions of children's motor competence (n = 10). Participants were assessed using TGMD-3. Coaches completed an adapted version of the pictorial scale of Perceived Movement Skill Competence. RESULTS: The predictive power of coaches perceived motor competence versus children's actual motor competence was assessed. CONCLUSIONS: This research will provide insight for sports organisations to determine whether coaches can accurately report on the motor competence of children with intellectual disabilities.

Assessing the Fundamental Movement Skills of Children With Intellectual Disabilities in the Special Olympics Young Athletes Program.

Mastering the ability to move proficiently from a young age is an important contributor to lifelong physical activity participation. This study examined fundamental movement skill (FMS) proficiency in children with intellectual disabilities (n = 96, 60% boys, age 5-12 years) and typically developing children (n = 96, 60% boys, age 5-12 years). Participants were assessed using the Test of Gross Motor Development-3rd edition and balance subtest from the Bruininks-Oseretsky Test of Motor Proficiency 2. The FMS proficiency of typically developing children including mastery/near mastery level (combined variable representing mastery, which is achieving all criteria for the skill, over both trials and near mastery, wherein a participant performs all but one of the components of the skill correctly) was significantly higher than for children with intellectual disabilities. A similar observation was made with multiple linear regression analysis testing the interaction effect of participant group and age/gender on all three FMS subcomponents. The results presented will help establish a baseline of FMS proficiency and guidelines for future intervention for children with intellectual disabilities.

The Effect of Hormonal Contraceptive Use on Skeletal Muscle Hypertrophy, Power and Strength Adaptations to Resistance Exercise Training: A Systematic Review and Multilevel Meta-analysis.

BACKGROUND: Resistance exercise training is widely used by general and athletic populations to increase skeletal muscle hypertrophy, power and strength. Endogenous sex hormones influence various bodily functions, including possibly exercise performance, and may influence adaptive changes in response to exercise training. Hormonal contraceptive (HC) use modulates the profile of endogenous sex hormones, and therefore, there is increasing interest in the impact, if any, of HC use on adaptive responses to resistance exercise training. OBJECTIVE: Our aim is to provide a quantitative synthesis of the effect of HC use on skeletal muscle hypertrophy, power and strength adaptations in response to resistance exercise training. METHODS: A systematic review with meta-analysis was conducted on experimental studies which directly compared skeletal muscle hypertrophy, power and strength adaptations following resistance exercise training in hormonal contraceptive users and non-users conducted before July 2023. The search using the online databases PUBMED, SPORTDiscus, Web of Science, Embase and other supplementary search strategies yielded 4669 articles, with 8 articles (54 effects and 325 participants) meeting the inclusion criteria. The methodological quality of the included studies was assessed using the "Tool for the assessment of study quality and reporting in exercise". RESULTS: All included studies investigated the influence of oral contraceptive pills (OCP), with no study including participants using other forms of HC. The articles were analysed using a meta-analytic multilevel maximum likelihood estimator model. The results indicate that OCP use does not have a significant effect on hypertrophy [0.01, 95% confidence interval (CI) [- 0.11, 0.13], t = 0.14, p = 0.90), power (- 0.04, 95% CI [- 0.93, 0.84], t = - 0.29, p = 0.80) or strength (0.10, 95% CI [- 0.08, 0.28], t = 1.48, p = 0.20). DISCUSSION: Based on the present analysis, there is no evidence-based rationale to advocate for or against the use of OCPs in females partaking in resistance exercise training to increase hypertrophy, power and/or strength. Rather, an individualised approach considering an individual's response to OCPs, their reasons for use and menstrual cycle history may be more appropriate. REGISTRATION: The review protocol was registered on PROSPERO (ID number and hyperlink: CRD42022365677).

Exploring the motor skill proficiency barrier among children with intellectual disabilities: Analysis at a behavioural component level.

Models of childhood motor development began to emerge in the 1960's. Since then, numerous models have proposed the importance of obtaining a proficient level of fundamental movement skill (FMS) competence during childhood and deemed it to be critical for participation in lifelong sports and physical activity. This study examined FMS at the behavioural component level in children with intellectual disabilities (CwID) (n = 100, 60% boys, aged 5-12 years). Participants were assessed using the Test of Gross Motor Development 3rd edition (TGMD-3) and the balance subtest from Bruininks-Oseretsky Test of Motor Proficiency 2 (BOT-2). For the whole sample, 0% participants mastered all 10 FMS, 1% (n = 1) participants mastered all 4 locomotor skills while 0% (n = 100) participants mastered all ball skills. A multiple regression was carried out to investigate whether the interaction of gender and age was a predictor of FMS proficiency. Linear regressions were also carried out to investigate whether gender or age was a predictor of FMS proficiency. The results presented will help to identify weaknesses in skills at the behavioural component level and will enable researchers and practitioners to address low levels of motor skill proficiency among CwID.

The Effect of Chronic Exercise on Energy and Fatigue States: A Systematic Review and Meta-Analysis of Randomized Trials.

In this meta-analysis, we synthesized the results of randomized controlled trials of different exercise training interventions on participants' feelings of fatigue, energy, and vitality. The search of studies was conducted using six databases as well as several other supplementary search strategies available before December 2021. The initial search generated over 3,600 articles with 81 studies (7,050 participants) and 172 effects meeting the inclusion criteria. We analyzed the effects from the studies using a meta-analytic multivariate model and considered the potential moderating effect of multiple variables. Our analysis revealed exercise to decrease the feelings of fatigue by a small effect size (g = -0.374; 95% CI [-0.521, -0.227]), increase energy by a small-to-moderate effect size (g = 0.415; 95% CI [0.252, 0.578]), and to increase the feeling of vitality by a moderate effect size (g = 0.537; 95% CI [0.404, 0.671]). All main results remained robust after several sensitivity analyses using different statistical estimators, and consideration of outlier and influential studies. Moreover, moderator analyses revealed significant effects of exercise intensity and intervention duration on fatigue, exercise intensity, and modality on energy, and participant health, exercise intensity modality, and exercise training location on vitality. We conclude that when groups adopt a moderate intensity exercise training program while participating in a randomized trial, compared to controls, this typically results in small-to-moderate average improvements in feelings of fatigue, energy, and vitality.
