As a step toward understanding the developmental relationship between handedness and language lateralization, this longitudinal study investigated how infants (N = 21) move their hands in noncommunicative and communicative situations at 2 weeks and at 3 months of age. The authors looked at whether left-right asymmetry in hand movements and in duration of self-touch appeared across conditions and whether the direction of asymmetry depended on the communicative nature of the situation. The authors found that asymmetries appeared less consistently than suggested in literature and did not only depend on the communicative nature of the situation. Instead, hand activity and self-touch patterns depended on age, the presence of the mother, the degree of novelty of the situation, and the presence of an object. The results partly support previous studies that pointed out an early differentiation of communicative hand movements versus noncommunicative ones in infants. It is in terms of the amount of global hand activity, rather than in those of the laterality of hand movements that this differentiation emerged in this study. At 3 months, infants moved their hands more in the communicative conditions than in the noncommunicative conditions and this difference appeared as a tendency already at 2 weeks of age.

Purpose: To facilitate precise diagnosis and provide tailored treatment of postural anomalies in the pediatric population, appropriate assessments are essential. In light of the multicomponent structure of postural control, understanding underlying constructs of an assessment is valuable in selecting and interpreting assessments. This study investigates the construct validity of the Gaits and Stations variables in the Revised Physical and Neurological Examination of Subtle Signs, a measure used to evaluate standing postural control in youth with mild neurological deficits. Methods: Data were included from 350 healthy participants ages 10–19 years old. An exploratory factor analysis with varimax rotation was performed. Individual loadings of ≥0.4 were used for factor designation. Results: Three latent factors were identified and labeled, based on evidence, as dynamic stability, movement strategies/coordination, and underlying motor systems—musculoskeletal strength. Conclusions: These brief, easily administered Gaits and Stations measures of the Physical and Neurological Examination of Subtle Signs facilitate evaluation of three constructs of standing postural control relevant to youth with mild neuromotor impairments. This information will potentially assist in clinical practice to identify youth with postural control deficits and establish developmentally appropriate interventions and in research to refine understanding of pathology and the impact on components of postural control.

Background: Children with developmental coordination disorder (DCD) frequently have difficulties performing gross motor skills such as the overarm throw. Our study examines the differences in both qualitative and quantitative characteristics of overarm throwing for accuracy between typically developing (TD) and children with DCD. Methods: A total of 74 children (36 females/38 males) aged between 7 and 11 years, participated in this study. The authors used the Movement Assessment Battery for Children—second edition to assess motor impairment. In total, 37 (50%) met the criteria for DCD. Each participant completed 10 overarm throws for accuracy at a target. The authors assessed movement quality using the component approach (Roberton & Halverson, 1984) and quantity using target accuracy. Results: The analyses revealed significantly lower throwing accuracy in DCD versus TD children. Children with DCD also demonstrated fewer component combinations and lower developmental levels than their TD peers. Finally, product scores tracked with process scores. Discussion: Both qualitative and quantitative measures clearly showed that children with DCD are at a disadvantage in controlling a ball during overarm throwing. They used stability profiles that limited coordination variability. TD participants performed more combinations of higher developmental levels to achieve more accurate throws, suggesting they controlled variability to optimize the accuracy of their throws.

This review addresses the question of a possible specificity of motor development of preterm children with no diagnosis of neurological impairment or major cerebral lesion. With that goal, we proceed with a narrative review on the basis of nine studies. All the studies used standardized assessments of motor abilities with a comparison methodology of preterm and full-term groups aged between 3 and 8 years. The review stresses three major findings in the preterm groups as compared with the full-term groups: (a) inferior fine motor abilities; (b) heterogeneity in motor skills; and (c) differences in efficiency of cognitive, perceptual, and mobilization of perceptual motor processes, which do not necessarily result in lower scores in global performances. These findings suggest the need of long-term medical follow-up for all preterm children whether or not they are at risk for neurodevelopmental disorder. Focusing attention on the use of sensory information for motor control in preterm children could also lead to more precise evaluations of motor abilities, which will then provide more detailed parameters for improved learning and rehabilitation programs.

The purpose of this study was to examine the distance of varying focus of attention for experienced and novice golfers on a golf putting task. Forty-eight experienced and 48 novice golfers were randomized into four attentional focus conditions: control (no instruction), internal (i.e., focus on the arm movement), external proximal (i.e., focus on the golf club), and external distal (i.e., focus on the target) conditions. Performance outcomes (the perceived level of confidence and number of golf putts made) were recorded. Experienced golfers had better performance outcomes than novice golfers. The external proximal focus was specifically beneficial for novice golfers, while experienced golfers had an advantage in both external focus instructions. The external proximal focus might enable a perception-action process for novice golfers to compare the relationship between action planning and the surrounding environment. In addition, the transition to expertise might result in no difference between both external focus instructions for experienced golfers.

Adults (N = 54, 80.78 ± 6.08 years) who reported falling during the previous 12 months participated in a 12-week wobble board training program with internal focus or external focus (EF) instructions. Verbal manipulation checks were performed after training sessions as a self-report of the attentional foci used. The percentage of sessions in which participants reported using an EF (EFSR) was subsequently calculated. Mean velocity and mean power frequency in the anterior–posterior (MVELOAP and MPFAP) and medial–lateral (MVELOML and MPFML) direction were assessed during a 35-s wobble board task at Weeks 0, 6, 12, 13, 16, and 20, with the latter three as retention tests. Piecewise linear growth models estimated treatment effects on individual growth trajectories of MVELOAP and ML and MPFAP and ML during intervention and retention periods. Regardless of condition, MVELOML significantly decreased (π = −.0019, p = .005) and MPFML increased (π = .025, p < .02) during the intervention period. In analyses including interaction terms, participants in the EF group who reported greater EFSR had superior progression of MPFAP during the intervention (π = .0013, p = .025). Verbal manipulation checks suggest a preference for and advantage of EF for facilitating postural control performance and automaticity.

The aim of this study was to compare two methodologies employed by the British Cycling talent identification program. Specifically, the authors investigated cyclists selected to represent GB cycling team at the London 2012 Olympics using (a) a traditional talent identification methodology (British Cycling Olympic Development Program), where selection is based upon race results and (b) a detection talent identification methodology (U.K. Sport Talent Team Program), which is a multi-Olympic event initiative that identifies athletic potential from physical and skill-based tests. To facilitate this comparison, the authors calculated the speed with which expertise was acquired. A Mann–Whitney U test (U = 16.0, p = .031) indicated that the speed of acquiring expertise was quicker in detection talent identification (Mdn = 5.4) than traditional talent identification (Mdn = 7.2). Practice started later with detection talent identification than with traditional talent identification (14.12 years vs. 11.23 years, respectively), which affected the period to excellence. Thus, detection talent identification resulted in an absence of early specialization, which suggests a critical period for attaining cycling expertise. The authors hypothesize a genetic basis of talent and propose that critical periods are important in detection talent identification programs.

Contemporary learning and development models have identified parkour-style training as a vehicle for athlete enrichment. However, perceptions of team-sport coaches and their receptiveness to such models of athlete enrichment have not been investigated and remain unclear. To explore how parkour-style training could be integrated into athlete development programs in team sports, we interviewed sport practitioners to explore their preexisting knowledge of parkour and their perceptions on its potential applications. Experienced talent development (n = 10) and strength and conditioning coaches (n = 10) were interviewed using an open-ended, semistructured approach with a two-stage thematic analysis being conducted to identify themes. Three dimensions were identified: coaches’ general perceptions of parkour, potential applications of parkour, and feasibility of integrating parkour into athlete development programs. Participant perceptions revealed that: (a) parkour activities were viewed as supplementary activities to enrich sport-specific training routines, including use of obstacle courses and/or tag elements; (b) parkour-style obstacle environments needed to be scalable to allow individual athletes and coaches to manipulate object orientation and tasks using soft play and traditional gym equipment; and (c) the implementation of continued professional development opportunities, athlete-centered approaches to learning designs in sport, and coach–parent forums were recommended to support the integration of parkour-style training.

Three dimensions were identified: coaches’ general perceptions of parkour, potential applications of parkour, and feasibility of integrating parkour into athlete development programs. Participant perceptions revealed that: (a) parkour activities were viewed as supplementary activities to enrich sport-specific training routines, including use of obstacle courses and/or tag elements; (b) parkour-style obstacle environments needed to be scalable to allow individual athletes and coaches to manipulate object orientation and tasks using soft play and traditional gym equipment; and (c) the implementation of continued professional development opportunities, athlete-centered approaches to learning designs in sport, and coach–parent forums were recommended to support the integration of parkour-style training.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"86 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74245198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study examined the test–retest reliability of the Ghent University dribbling test and short dribble test in a pediatric population. Fifty-four boys aged 9–14 years (mean ± SD = 11 ± 2 years) undertook the Ghent University and dribbling tests on two occasions separated by 2 weeks. Intraclass correlation coefficients, coefficient of variation, and 95% limits of agreement were conducted for each test. Intraclass correlation coefficients and coefficient of variation indicated good to excellent reliability, and relatively small variability for both dribbling tests. The 95% limits of agreement indicated relatively little bias Ghent University dribbling test for both running alone and running with the ball components, and the Bangsbo and Mohr short dribble test. The results of the present study suggest both dribbling tests examined in the present study demonstrate good reliability and low levels of systematic bias.
