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.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"30 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79071213","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}

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.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"47 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77923767","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}

Children ( N = 279; 156 girls; M age = 4.44 years) completed a battery of product-oriented assessments for throwing (in meters per second, five trials); kicking (in meters per second, five trials); jumping (in centimeters, five trials); running (in meters per second, two trials); and hopping (in meters per second, four trials—two preferred foot, two nonpreferred foot). A total of 36 performance metrics were derived—throw ( n = 7), kick ( n = 7), jump ( n = 7), run ( n = 4), and hop ( n = 11). Intraclass correlations examined reliability among performance metrics for each skill; linear mixed models examined whether variations changed across early childhood. There was excellent reliability among all performance metrics for each skill (all ICC > .90). Linear mixed models revealed that children’s motor performance improved for two metrics of the throw, five variations of the jump, and three metrics of the hop (all p < .05).

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.","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}

Data were analyzed from fifteen 4-month-old infants who participated in a 10-min mobile task on 2-3 consecutive days. Infants learned that their vertical leg movements above a systematically increased threshold height activated the mobile. Five kinematic variables were analyzed: 1) exploration space volume, 2) exploration path length, 3) duration of time in the region of interest around the threshold that activated the mobile, 4) task-specific vertical variance of kicks, and 5) non-task-specific horizontal variance of kicks. The infants increased their general spatial exploration, volume and path, and the infants adapted their exploration by maintaining their feet within the region of interest although the task-specific region increased in height as the threshold increased. The infants used task-specific strategies quantified by the increased variance of kicks in the vertical direction and no change in the horizontal variance of kicks. Quantifying infants' task exploration may provide critical insights into how learning emerges in infancy and enable researchers to more systematically describe, interpret, and support learning.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"10 1","pages":"167-183"},"PeriodicalIF":1.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10237591/pdf/nihms-1876564.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9956081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With players being required to execute a range of skills with hand and foot on both sides of the body, Gaelic football provides an ideal natural laboratory for the study of laterality. Previous quantitative research has produced equivocal findings regarding the importance of bilateral skill performance in sport. In light of this equivocality, this paper utilized a qualitative approach to distill the beliefs and experiences of 14 players and five coaches who had performed at the highest level in Gaelic football. Three higher order categories were produced from the transcripts: the importance of being bilaterally skilled, the potential to develop bilateral skill, and methods to develop bilateral skills. Overall, this study highlights lessons for the design of future quantitative studies of bilateral skill in sport and should stimulate reflection on current practice regarding both short- and long-term bilateral skill development on the part of researchers, applied sport scientists, and coaches.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"332 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80532987","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}

However, the combined effects of these approaches and the underlying mechanisms have yet to be studied. Therefore, the present study examined the effects of a large visual illusion and an external focus on the learning of a dart throwing task in novices and measured the perceptual mechanisms underpinning learning using quiet eye. Forty novice participants were randomly divided into four groups: large visual illusion, external focus of attention, combined large visual illusion and external focus of attention, and control group. The study consisted of a pretest, a practice phase, an immediate retention test, a 24-hr retention test, and a transfer test. Results revealed that all groups increased throwing accuracy and quiet eye duration from pretest to immediate retention. In the immediate retention, 24-hr retention, and transfer test, large visual illusion had greater accuracy and longer quiet eye duration than the control group. In addition, there were no significant differences between the visual illusion and external focus groups for throwing accuracy and quiet eye duration. The findings suggest that combining large visual illusion and external focus can independently improve motor learning but combining these manipulations does not have additive benefits.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"15 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82533293","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 purpose of this study was to examine the phenomenon of motor learning development due to application of task constraint in a training regimen following 6 weeks of training. Forty-five healthy adult males were randomly assigned to a control or one of two experimental constraint training groups (i.e., no arm swing or restricted knee flexion). Pre- and posttraining jump height and kinematic variables of six maximum effort countermovement jumps were compared longitudinally within the groups, and also compared between the groups. The findings of this study indicated that jump height significantly increased in all the groups while in the unrestricted control group it was increased greater than the experimental conditions (21% compared with 12% and 5.5%). However, the applied task constraints significantly improved some of the contributors to jump performance, establishing specific adaptation of kinematic variables to the constraint training. Therefore, constraint training approach could be suggested in case of demanding specific adaptation of kinematic variables of countermovement jump in a training regimen.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"28 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73397819","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}
