Motor competence as an indicator of gross motor development is characterized by changes in movement patterns and outcomes. The Test of Gross Motor Development-3 consists of six locomotor and seven ball tasks used to assess the quality of fundamental motor skills in children. The purpose of this study is twofold—to produce a Slovenian translation of Test of Gross Motor Development-3 and to evaluate it on a sample of Slovenian children. First, a back translation was carried out with the help of relevant field professionals, thus producing a Slovenian version of Test of Gross Motor Development-3 with excellent content validity. Second, trained assessors rated the video-recorded test tasks of 452 Slovenian children with smaller groups of measured participants repeating the procedure within 2- and 4-week interval to assess reliability. Finally, the collected data were analyzed using several statistical methods. The data showed good to excellent reliability for intrarater, interrater, test–retest reliability, structural validity, and internal consistency for the majority of motor skills, as well as good measurement invariance across genders.

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to jump over for continuous two-footed jumping and analyzed the movement time (MT), aerial time (AT), and contact time (CT), and variabilities in AT and CT in 7 year-based categories, using a high-speed camera. We also used multiple regression analysis to identify the predictors of MT. MT and CT shortened until 8 years, whereas AT continued to shorten after 8 years, suggesting that the jumping strategy differs between those younger/older than 8 years. MT, AT, and CT were significantly shorter among boys than girls from preschool children to high school students. In addition, when using multiple regression analysis, the main predictor of MT changed gradually from SD of CT to AT with increasing age. Our findings suggest that the motor control mechanisms related to continuous two-footed jumping differ depending on the age and sex and provide findings to advance understanding of the age-related motor coordination and agility in children.

Background: Understanding how or whether sedentary behavior affects motor competence in young children is important considering that children spend a lot of time sedentary. The aim of this study was to examine whether sedentary behavior predicts motor competence in young children. Methods: A longitudinal study with a total of 372 children aged 3.5 years at baseline and 5 years at follow-up was conducted. Objectively measured activity patterns (i.e., using accelerometers) were conducted in a subsample with 188 children. Sedentary behavior was assessed both objectively and subjectively (parent-reported screen time). Locomotor and object control skill scores were determined using the Test of Gross Motor Development—Second Edition. A multivariable analysis was executed adjusting for potential confounders (such as age, sex, time spent in moderate- to vigorous-intensity physical activity, monitor wear time, body mass index z scores, and maternal education). Results: Sedentary behavior at either time point was not significantly associated with either locomotor or object control skills after adjusting for potential confounders. Discussion: Our results did not support the assumption that sedentary behavior affects motor competence in young children. Regardless, given the lack of consistency in the evidence base, we recommend to parents, educators, and health professionals that sedentary activities should be kept within government recommendations due to potential negative effects on child development.

Different individuals learn different solutions to the same perceptual-motor task regardless of the fact that they may undergo the same practice conditions. In the current study, we characterized individual solutions to a perceptual-motor task. Eighteen self-declared right-handed participants were requested to intercept a moving target controlling a virtual ball using a computer mouse. Target speed varied across trials. Participants visited the lab 2 days in a row. They practiced 250 trials on Day 1 and 50 trials on Day 2. We assessed participants’ preferred speed and maximum speed on both days. We combined a qualitative description of solutions on the task space and the quantitative growth curve analysis to address individual differences. Results indicated an overall trend to increase the ball release speed to handle the task constraints. Moreover, the local shape of the solution manifold constrained individuals’ solutions. Contrary to our expectations, neither individual preferred speed nor individual maximum speed improved model fit.

Free throw shooting percentage has averaged around 75% for nearly five decades. However, free throw percentages significantly increased to 79% during the 2020 spectator-less National Basketball Association season. The current study investigated if the elevated free throw shooting percentage observed during the spectator-less season has returned to the 50-year average now that spectators have returned to National Basketball Association arenas. Moreover, home and away free throw percentages were examined to determine if a potential home-field advantage contributed to this phenomenon. Analyses revealed that the free throw shooting percentage from the spectator-less season was significantly higher than the two spectator-filled seasons preceding and following the spectator-less season. Furthermore, the analyses found no differences in free throw percentages between home and away games. While the free throw shooting percentage increased to 79% during the spectator-less season, the free throw shooting percentage returned to the 50-year average (i.e., ∼75%), following the spectator-less season. Additionally, it does not appear that a perceived home-field advantage influenced the increased free throw performance observed in the spectator-less season. Multiple factors likely contributed to this free throw phenomenon, including the environmental characteristics shaped by the lack of spectators.

This study examined differences in bilateral skill proficiency and frequency of use between selected and nonselected under-17 male intercounty academy Gaelic footballers. Participants ( N = 82, mean age = 15.54 years, SD = 0.27) were retrospectively grouped as selected ( n = 19) and nonselected ( n = 63) for the final squad. A discrete skills test evaluated bilateral hand pass and kick pass proficiency. Within-academy matches ( N = 8) were recorded to analyze in-game bilateral passing proficiency and frequency ( N = 3,109). Selected players were more proficient in both nondominant kick pass ( p = .001) and nondominant hand pass ( p = .007) in the discrete skills test and nondominant hand pass ( p = .002) in match play. Nonselected players used the dominant hand pass ( p = .037) significantly more than selected players in match play. The strongest predictors of selection were the nondominant kick pass and nondominant hand pass in the skills test, and successful dominant kick pass and successful nondominant hand pass in match play ( p < .05), with 89% of players correctly classified. The findings suggest that higher bilateral proficiency scores provide greater opportunities to be selected.

The focus of attention literature has shown robust findings for the benefits of providing statements that focus on the movement effect or outcome (external focus of attention [EFOA]) as opposed to focusing on the movement kinematics (internal focus of attention). Observational studies, however, have revealed that physiotherapists use fewer EFOA statements than internal focus of attention statements in their practice. Most evidence in this regard has been from non-Canadian physiotherapists working in stroke rehabilitation; consequently, we sought to examine whether Canadian physiotherapists working with various rehabilitation populations also use EFOA statements to a lesser extent than internal focus of attention statements. The “Therapists’ Perceptions of Motor Learning Principles Questionnaire (TPMLPQ)” was thus designed and data from 121 Canadian physiotherapists showed low relative frequencies of EFOA use (31.3% ± 14%) averaged across six hypothetical scenarios. A higher EFOA was reported, however, for two of the six scenarios: a functional reaching scenario (55.5% ± 37.0%) and pelvic floor task (65.6% ±32.9%). This data suggest that the findings of EFOA benefits have not been widely translated into Canadian physiotherapy settings; furthermore, the findings of the scenario-dependency warrant future investigation into factors, such as task characteristics, that may influence physiotherapists’ FOA use.

Poor single-leg balance performance is associated with an increased risk of sustaining lower limb injuries in team sports. However, it is unclear whether this relationship is modified by the level of training experience (years of training experience). The objective of the present study was to evaluate whether soccer players’ single-leg balance performance is related to lower limb injuries in noncontact situations with different levels of training experience. Subelite young male soccer players performed the Lower Quarter Y-Balance Test with the dominant and the nondominant leg at the beginning of the preseason. Due to COVID-19 rules, the occurrence of lower limb injuries during the second half of the competitive season was documented. The odds of injury were calculated based on a previously reported Lower Quarter Y-Balance Test cut-off score for side-to-side anterior reach difference (≥4 cm). Twelve soccer players sustained a lower leg injury in noncontact situations. Only four of them had an anterior reach difference equal to or above the cut-off score. Soccer training experience has no significant influence on the association between Lower Quarter Y-Balance Test anterior reach asymmetry and noncontact lower limb injury in young male players.

We aimed to calculate interrater reliability of the Test of Gross Motor Development—Third Edition (TGMD-3) after raters reached a consensus regarding measurement criteria. Three raters measured the fundamental movement skills of 25 children on the TGMD-3 at two different times: (a) once when simply following the measurement criteria in the TGMD-3 manual and (b) after a 9-month washout period, following the raters’ consensus building for the measurement criteria for each skill. After calculating and comparing the interrater reliability of these three raters across these two rating times, we found improved interrater reliability after the raters’ consensus-building discussions on ratings of both locomotor skills (moderate-to-good reliability on two of six skills initially and at least moderate-to-excellent on four of six skills following criteria consensus building) and ball skills (moderate-to-good reliability on one of seven skills initially and at least moderate-to-excellent reliability on four of seven skills following criteria consensus building). For subtest scores and overall test scores, raters achieved at least moderate-to-good reliability on their second, postconsensus-building ratings. Based on this improved reliability following consensus building, we recommend that researchers include rater consensus building before assessing children’s fundamental movement skills or guiding curriculum interventions in physical education from TGMD-3 data.

The natural development of static lower limb varus/valgus alignments during early childhood is well understood. However, our understanding of dynamic lower limb frontal plane alignments is limited, and we lack normative descriptions of this phenomenon for both boys and girls. This study investigated dynamic lower limb alignment during jump-landings in preschool children, focusing on associations with sex, age, and motor performance. Dynamic lower limb alignment was measured as the Knee-to-Ankle Separation Ratio (KASR) in 605 children aged 3–6 years using markerless motion capture. Based on KASR measurements, we categorized the children into three kinematic groups: Valgus, Intermediate, and Varus. Median KASR scores were 0.86 (0.80–0.96) overall, 0.89 (0.81–0.98) for boys, and 0.85 (0.78–0.92) for girls. Over 75% of the children exhibited some level of dynamic knee valgus during jump-landings (KASR < 1). However, roughly two-thirds of the children in the Valgus group were girls. Age-adjusted differences in motor performance were small and only statistically significant for jump height and length in girls. These findings suggest that dynamic knee valgus during jump-landings is a common occurrence in preschool children, especially among girls. The potential relationship between dynamic lower limb alignment and age and motor performance warrants further investigation.

Median KASR scores were 0.86 (0.80–0.96) overall, 0.89 (0.81–0.98) for boys, and 0.85 (0.78–0.92) for girls. Over 75% of the children exhibited some level of dynamic knee valgus during jump-landings (KASR < 1). However, roughly two-thirds of the children in the Valgus group were girls. Age-adjusted differences in motor performance were small and only statistically significant for jump height and length in girls. These findings suggest that dynamic knee valgus during jump-landings is a common occurrence in preschool children, especially among girls. The potential relationship between dynamic lower limb alignment and age and motor performance warrants further investigation.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135704110","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}
