Motor Skill, Movement Competency, and Physical Fitness Assessments for Reserve Officers' Training Corps Cadets

ABSTRACT Reserve Officers' Training Corps (ROTC) is used at high schools and universities to prepare individuals for enlistment and commission in the U.S. military. Population demographic changes have resulted in more adolescents and young adults being less active, which influences motor skill, movement, and fitness development. Because ROTC programs recruit from the general population, this could influence the training programmed by ROTC staff or strength coaches. This article presents assessment options for motor skills, movement competency, and physical fitness that could be used for ROTC cadets. Should these tests be adopted, staff can use the results to drive their training.

Skill Acquisition Methods Fostering Physical Literacy in Early-Physical Education (SAMPLE-PE): Rationale and Study Protocol for a Cluster Randomized Controlled Trial in 5-6-Year-Old Children From Deprived Areas of North West England.

BackgroundThere is a need for interdisciplinary research to better understand how pedagogical approaches in primary physical education (PE) can support the linked development of physical, cognitive and affective aspects of physical literacy and physical activity behaviors in young children living in deprived areas. The Skill Acquisition Methods fostering Physical Literacy in Early-Physical Education (SAMPLE-PE) study aims to examine the efficacy of two different pedagogies for PE, underpinned by theories of motor learning, to foster physical literacy.MethodsSAMPLE-PE will be evaluated through a cluster-randomized controlled trial targeting 5–6 year old children from schools located in areas of high deprivation in Merseyside, North-West England. Schools will be randomly allocated to one of three conditions: Linear Pedagogy, Non-linear Pedagogy, or Control. Non-linear and Linear Pedagogy intervention primary schools will receive a PE curriculum delivered by trained coaches over 15 weeks, while control schools will follow their usual practice. Data will be collected at baseline (T0), immediately post-intervention (T1), and 6 months after the intervention has finished (T2). Children’s movement competence is the primary outcome in this trial. Secondary outcomes include physical activity, perceived competence, motivation, executive functions, and self-regulation. An extensive process evaluation will also examine implementation factors such as intervention context, reach, dose, fidelity and acceptability.DiscussionThe SAMPLE-PE project will enable better understanding surrounding how to operationalise physical literacy through enrichment of PE practices in early PE. The study will provide robust scientific evidence regarding the efficacy of underpinning PE pedagogy with theories of motor learning to promote the development of physical literacy.Trial RegistrationRetrospectively registered on 5th September 2018 at ClinicalTrials.gov, a resource provided by the U.S. National Library of Medicine (Identifier: NCT03551366).

Competencies for a Healthy Physically Active Lifestyle-Reflections on the Model of Physical Activity-Related Health Competence.

The World Health Organization's Global Action Plan on Physical Activity 2018-2030 states that physical activity interventions should strengthen peoples' competencies for health. Yet, frameworks that bundle pivotal competencies for a healthy and physically active lifestyle have not been extensively discussed in the past. In the present article, the authors therefore present the model of Physical Activity-related Health Competence (PAHCO), an integrative structure model including the 3 areas of movement competence, control competence, and self-regulation competence. After providing a rationale for the use of the competence concept, the authors focus on implications from the PAHCO model to guide interventions for the promotion of a healthy and physically active lifestyle. The authors argue that the PAHCO model is located at the interface between health literacy and physical literacy, research areas that have gained increasing scholarly attention in recent years. In addition, PAHCO appears to be compatible with the concept of health capability because it can represent the important aspect of agency. The article concludes with a scientific positioning of model components and some empirical results that have been accumulated so far.

Cueing the Youth Athlete During Strength and Conditioning: A Review and Practical Application

ABSTRACT Verbal cues are tools used by practitioners in developing a youth athlete's motor skill abilities. External cues may optimize athletic performance and movement competencies in adults with trends for youth athletic populations following suit. However, maturation, training age, and cognitive age may interact with the efficacy of cues used. To better assist practitioners working with youth, this article reviews current empirical evidence on how youth populations respond or may respond to cues and offers practical applications.

FUNCTIONAL MOVEMENT AND DYNAMIC BALANCE IN ENTRY LEVEL UNIVERSITY DANCERS

Dance requires integration and synergy between movement, postural stability, and body alignment to effectively execute the technical and aesthetic requirements of the performance. Evaluation of movement competency and dynamic balance provides opportunity to identify dysfunctional movement which may negatively impact both artistic and technical aspects of dance performance. Investigation of the relationships between movement competency and postural control may aid in technical development, performance improvement, and ultimately injury reduction. Although the Functional Movement Screen™ (FMS™) and Y-Balance Test (YBT) have assessed movement competency in athletes, they have not been used extensively in the performing arts. The purposes of this investigation were to examine movement competency in university dancers using the FMS™ and YBT and to determine the relationship between functional movement and dynamic balance. Cross sectional. Fifteen, injury-free, female members (19.1 ± 1.18 years old) of an introductory university ballet class volunteered to participate. Pearson product correlations were used to determine relationships between variables. The mean composite FMS™ score was 15.32 ± 2.30. Shoulder mobility (SM) (r = 0.63, p = 0.01), In-line lunge (ILL) (r = 0.64, p = 0.01), and Deep Squat (DS) (r = 0.62, p = 0.01) were correlated with composite FMS™ score. Overall composite YBT score was 86.62% ± 8.17%. Reach asymmetry was 3.25 cm ± 3.53 cm (anterior), 4.06 cm ± 3.59cm (posteromedial (PM)), and 3.28cm ± 2.61cm (posterolateral (PL)). Composite FMS™ score was not correlated with composite YBT composite score (r = 0.44, p = 0.10). A moderate to good correlation was found between the ILL and YBT composite score (r = 0.64, p = 0.01). Collectively the results indicate the FMS™ and YBT do not measure the same constructs. However, the associations between individual components of the FMS™ and YBT indicate a relationship between certain movements and dynamic balance, supporting their combined use in a dancer injury risk management program. 2b.

Effect of Biological Maturation on Performance of the Athletic Ability Assessment in Australian Rules Football Players.

To determine the effect of biological maturation on athletic movement competency as measured using the Athletic Ability Assessment-6. Fifty-two junior Australian Rules football players were split into 3 groups based on proximity to peak height velocity, while 46 senior players were split into 2 groups based on playing status. The subjects completed the Athletic Ability Assessment-6 (inclusive of the overhead squat, double lunge, single-leg Romanian dead lift, push-up, and chin-up). All subjects were filmed and retrospectively assessed by a single rater. A 1-way analysis of variance and effect-size statistics (Cohen d) with corresponding 90% confidence intervals were used to describe between-groups differences in the component movement scores. The statistical significance was set a priori at P < .05. There were significant between-groups differences for all component movements (P < .05). Post hoc testing revealed that older, more mature subjects possessed greater competency in all movements except the overhead squat. The effect sizes revealed predominantly moderate to very large differences in competency between the senior and junior groups (range of d [90% confidence interval]: 0.70 [0.06 to 1.30] to 3.01 [2.18 to 3.72]), with unclear to moderate differences found when comparing the 3 junior groups (0.08 [-0.50 to 0.65] to 0.97 [0.22-1.61]). The findings suggest that biological maturation may be associated with changes in athletic movement competency in youth Australian Rules football players. Therefore, it is recommended that strength and conditioning coaches monitor maturity status when working with 12- to 15-y-old players. This can allow for a comparison of an individual's athletic movement competency to maturity-based standards and help guide developmentally appropriate training programs.

Outcomes and Feasibility of a 12-Week Physical Literacy Intervention for Children in an Afterschool Program.

Children (N = 90) from eight afterschool programs (n = 4 experimental sites with 47 children; n = 4 control sites with 43 children), along with the program leaders (N = 7) from the experimental sites, participated in a 12-week physical literacy intervention. Children were assessed on their physical literacy (movement competence, affect, confidence, and motivation) pre- and post-intervention using a suite of assessment tools that included the PLAYfun assessment of movement competence and a comprehensive child questionnaire. Experimental participants engaged in a daily physical literacy intervention at their afterschool program; controls engaged in their usual afterschool programming. Experimental group program leaders were assessed on their cognitions pre- and post-training and post-intervention, alongside questions regarding program acceptability and feasibility. Program leaders’ perceived knowledge and self-efficacy to implement the physical literacy program increased (p < 0.05) from pre- to post-training and these effects were maintained at post-intervention. No group differences were observed in the change of children’s motor competence, self-efficacy, or motivation from baseline to post-intervention. However, significant increases in affect were observed among participants in the experimental group (p < 0.05). Program leaders said they would recommend the program to future leaders. However, they reported challenges with implementation due to equipment availability and behavioral challenges. Results suggest a comprehensive physical literacy program during the afterschool period can be feasible to implement and can lead to improvements in the affective domain of children’s physical literacy. Further research on childhood physical literacy interventions is warranted.

Exploring the Application of Pattern Recognition and Machine Learning for Identifying Movement Phenotypes During Deep Squat and Hurdle Step Movements.

BackgroundMovement screens are increasingly used in sport and rehabilitation to evaluate movement competency. However, common screens are often evaluated using subjective visual detection of a priori prescribed discrete movement features (e.g., spine angle at maximum squat depth) and may not account for whole-body movement coordination, or associations between different discrete features.ObjectiveTo apply pattern recognition and machine learning techniques to identify whole-body movement pattern phenotypes during the performance of exemplar functional movement screening tasks; the deep squat and hurdle step. Additionally, we also aimed to compare how discrete kinematic measures, commonly used to score movement competency, differed between emergent groups identified via pattern recognition and machine learning.MethodsPrincipal component analysis (PCA) was applied to 3-dimensional (3D) trajectory data from participant’s deep squat (DS) and hurdle step performance, identifying emerging features that describe orthogonal modes of inter-trial variance in the data. A gaussian mixture model (GMM) was fit and used to cluster the principal component scores as an unsupervised machine learning approach to identify emergent movement phenotypes. Between group features were analyzed using a one-way ANOVA to determine if the objective classifications were significantly different from one another.ResultsThree clusters (i.e., phenotypes) emerged for the DS and right hurdle step (RHS) and 4 phenotypes emerged for the left hurdle step (LHS). Selected discrete points commonly used to score DS and hurdle step movements were different between emergent groups. In regard to the select discrete kinematic measures, 4 out of 5, 7 out of 7 and 4 out of 7, demonstrated a main effect (p < 0.05) between phenotypes for the DS, RHS, and LHS respectively.ConclusionFindings support that whole-body movement analysis, pattern recognition and machine learning techniques can objectively identify movement behavior phenotypes without the need to a priori prescribe movement features. However, we also highlight important considerations that can influence outcomes when using machine learning for this purpose.

Assessing the Internal Reliability and Construct Validity of the General Movement Competence Assessment for Children

Validated assessment tools for movement competence typically involve the isolation and reproduction of specific movement forms, which arguably neglects individuals’ ability to combine and adapt movements to overcome constraints within a dynamic environment. A new movement assessment tool, the General Movement Competence Assessment (GMCA), was developed for this study using Microsoft Kinect. Movement competence of 83 children (36 boys and 47 girls), aged 8–10 years (9.06 ± 0.75 years) was measured using the GMCA. An exploratory approach was undertaken to examine the internal consistency reliability (McDonald’s omega coefficient) and factorial structure of the GMCA for the study sample. Factorial structure was determined using exploratory factor analysis by principal component analysis with varimax rotation. For the sample data, reliability for the GMCA games were acceptable (ω = 0.53–0.89) and indicated that combinations of movement attributes were measured by GMCA games. Factorial analysis extracted four movement constructs accounting for 71.31% of variance. Dexterity was tentatively identified as a new independent construct alongside currently accepted movement constructs (i.e., locomotion, object-control, stability). While further development of the GMCA is still required, initial results are encouraging in view of an objective and theoretically informed approach to assess general movement competence in children.

Movement Competency Training Delivery: At School or Online? A Pilot Study of High-School Athletes

Movement competency (MC) development of high-school athletes can prepare them for the requirements of physical preparation training and the demands of sport. The aim of this study was to explore the physical effects of and athlete compliance to coach-led versus self-directed training approaches in this population. Thirty-nine high-school athletes (19 male, 14.5 ± 0.3 years old; 20 female, 14.6 ± 0.3 years) were allocated into two groups for a physical preparation program to improve MC. Groups were prescribed either (i) one face-to-face and one online (F2F, n = 18), or (ii) two online (OL, n = 21) sessions per week for 16-weeks. Before and after the intervention, the Athlete Introductory Movement Screen (AIMS) was used to assess MC alongside common physical capacity measures (triple-hop, star-excursion balance, medicine ball throw, 40 m sprint and countermovement jump). Dropout left 22 participants with pre-post physical scores. Compliance with online training was low and F2F session attendance moderate. Semi-structured interviews were conducted to assess participant perceptions following the intervention. Assessing individual responses, the F2F group had a higher proportion of positive responders to AIMS scores, yet capacity measures were inconclusive across groups. Face-to-face coaching when acquiring MCs as part of physical preparation, may provide greater positive perceptions towards training compared to self-directed online prescriptions, and thereby greater compliance.

The Effects of Strength and Conditioning on Functional Movement Screen™ Scores in Secondary School Basketball

Purpose: Injury prevention and mitigation are among the primary responsibilities of Athletic Trainers. Research has indicated that basketball players at the secondary-school level suffer up to 2.1 time loss injuries (TLI) per 1,000 athletic exposures (AE). It has been suggested that Functional Movement Screen (FMS™) composite and individual task scores may help determine injury risk. Researchers have suggested that a variety of strength and conditioning strategies may positively alter both composite and individual FMS™ task scores and reduce movement asymmetry. Methods: During a retrospective analysis of the records of all junior varsity and varsity basketball players at one secondary school over one season, no TLI was recorded over 1900 AE following the implementation of team-specific strength and conditioning programming. Results: Significant increases in pre-season and post-season composite FMS™ scores (pre-season mean = 14.33 ± 1.84; post-season mean = 16.44 ± 1.72; p < 0.001), and FMS™ individual task scores; deep squat (DS) (p < 0.001), hurdle step (HS) (p = 0.002), in-line lunge (INL) (p = .011), active straight leg raise (ASLR) (p = .02), and rotatory stability (RS) (p = .005) were noted across 27 male and female participants. Among females, composite FMS™ scores changed significantly (pre-season mean = 14.92 ± 1.38; post-season mean = 17.00 ± 1.04; p < 0.001), as did HS (p < 0.001) and INL (p = .025). Among males, significant changes were noted in composite FMS™ scores (pre-season mean = 13.87 ± 2.07; post-season mean = 16.00 ± 2.04; p < 0.001), as well as DS (p = 0.007), and RS (p = .025). Reductions in the number of scores of one and movement asymmetries were also evident during post-season FMS™ screening. Conclusions: Emphasizing movement competency and strength and conditioning training has positive effects on injury risk reduction in secondary school basketball players.

Monitoring the Return to Sport Transition After ACL Injury: An Alpine Ski Racing Case Study.

Alpine ski racing is an extreme sport and ski racers are at high risk for ACL injury. ACL injury impairs neuromuscular function and psychological readiness putting alpine skiers with ACL injury at high risk for ACL reinjury. Consequently, return to sport training and testing protocols are recommended to safeguard ACL injured athletes against reinjury. The aim of this paper was to present a real-world example of a return to sport training plan for a female elite alpine ski racer who sustained an ACL injury that was supported by an interdisciplinary performance team (IPT) alongside neuromuscular testing and athlete monitoring. A multi-faceted return to sport training plan was developed by the IPT shortly after the injury event that accounted for the logistics, healing, psychological readiness, functional milestones, work capacity and progression to support the return to sport/return to performance transition. Neuromuscular testing was conducted at several timepoints post-injury. Importantly, numerous pre-injury tests provided a baseline for comparison throughout the recovery process. Movement competencies and neuromuscular function were assessed, including an evaluation of muscle properties (e.g., the force-velocity and force-length relationships) to assist the IPT in pinpointing trainable deficits and managing the complexities of the return to sport transition. While the athlete returned to snow 7 months post-injury, presenting with interlimb asymmetries below 10%, functional and strength deficits persisted up to 18 months post-injury. More research is required to establish a valid return to sport protocol for alpine ski racers with ACL injury to safeguard against the high risk for ACL reinjury.

Movement competence: Association with physical self-efficacy and physical activity

BackgroundThe purpose of this paper was to investigate whether physical self-efficacy mediates the relationship between movement competence (fundamental movement skills and perceived movement skill competence) and physical activity in children. MethodsA purposive sample of 860 children (47.7% female, 10.9 ± 1.16 years) were recruited and completed assessments for physical self-efficacy (Physical Activity Self-Efficacy Scale), fundamental movement skills (Test of Gross Motor Development-3), perceived movement skill competence (Pictorial Scale of Perceived Movement Skill Competence), and physical activity (PACE+). A bootstrap mediation analysis was employed using movement competence as the predictor variable and physical activity as the outcome variable, and physical self-efficacy as the potential mediator of the relationship. ResultsThe results from a bootstrap mediation analysis yielded a statistically significant mediation effect for physical self-efficacy, with the entire model explaining approximately 10.3% of the variance of physical activity. The indirect effect of perceived movement skill competence through physical self-efficacy was significantly larger than the indirect effect of fundamental movement skills through physical self-efficacy. Neither sex nor age acted as a covariate. ConclusionMovement competence (fundamental movement skills and perceived movement skill competence) acts as a source of information for children's physical self-efficacy, moreover physical self-efficacy mediates the movement competence – PA relationship. Findings highlight the need for interventions to target and improve movement competence as a whole for children.

Intervention strategies for enhancing movement competencies in youth athletes: A narrative systematic review

This systematic review evaluates empirical evidence for intervention studies targeting delivery and improvement of movement competency (MC) within youth athletes. Previous research suggests that youth athletes lack adequate MCs required to meet the demands of training for sport. From the systematic search, studies were included if they involved healthy youth (8–19 years) involved in organised sport (i.e. athletes); used an assessment at two or more time points for assessing MC outcomes; and compared movement quality of a targeted intervention group to a control or comparison group. After removing duplicates, 799 unique articles across six databases were identified and screened, with six studies initially satisfying inclusion criteria. Additional records were identified through searching reference lists ( n = 2), with eight articles included. Two authors evaluated and appraised studies for methodological quality using the PEDro assessment; with scores from 4 to 7 points. Five studies reported improvement in ratings of MC in experimental groups, compared to control or comparator groups. The Functional Movement Screen™ was the most common assessment used in five studies. Intensity, length and design of interventions varied, yet all studies revealed inclusion of squats and their derivatives to varying degrees of load from bodyweight to barbells. Future research should explore differences in training session exposures over time, alongside methodological improvements such as participant allocation to minimise baseline differences, blinding of assessors, and where possible athletes to some degree. Charting the course of MC development through multiple time points, along with reporting individual movement task scores, can aid practitioners in dedicating appropriate time to MC development in an athlete’s formative years.

Effects of a 12-Week Training Program on Isometric and Dynamic Force-Time Characteristics in Pre- and Post-Peak Height Velocity Male Athletes.

Dobbs, IJ, Oliver, JL, Wong, MA, Moore, IS, and Lloyd, RS. Effects of a 12-week training program on isometric and dynamic force-time characteristics in pre- and post-peak height velocity male athletes. J Strength Cond Res 34(3): 653-662, 2020-Literature shows that training children and adolescents can enhance strength and power irrespective of their stage of development; however, the development of the kinetic variables that underpin strength and power performance are typically unreported in youth training studies. Twenty-four pre- and 14 post-peak height velocity (PHV) male athletes were divided into maturity-specific experimental (EXP) and control groups (CON), with the EXP groups completing a twice-weekly, 12-week training program. Force-time characteristics during the isometric midthigh pull (IMTP), countermovement jump, and squat jump tests were quantified at both baseline and after the completion of the 12-week program. Alpha level was set at p < 0.05. No changes in total score for back-squat assessment were observed in any group (p > 0.05). Analysis of IMTP data revealed that only the post-PHV EXP group significantly increased absolute isometric peak force (PFabs) and peak rate of force development within the IMTP after training. Both EXP groups displayed significant increases in isometric PF at time epochs 0-90, 0-150, 0-200, and 0-250 ms. Data from the dynamic tests indicated that the pre-PHV EXP cohort improved concentric qualities as reflected by increased squat jump height and countermovement jump concentric power. There were no significant changes for any variables across all tests within either CON group (p > 0.05). Maturity-related differences in response to short-term training affects the kinetic variables associated with strength and power performance, but not movement competency in young male athletes.

The Assessment of Movement Competence in Czech School Age Children Using BOT-2 Test

Introduction: A sufficient level of movement competence (MC) is a significant health and psychosocial factor. Overall, there is a strong consensus that movement competence is positively associated with all health-related variables. A lower level of movement competence in childhood is reflected in physical activity participation and engagement in physical activity later in life. The Bruininks-Oseretsky test of motor proficiency, 2nd version (BOT-2), is considered the most comprehensive diagnostic tool. There are no normative criteria of this test in the Czech Republic. The aim of this pilot study was to estimate a cross-cultural validity of the BOT-2 in a sample of Czech school children. Methods: The research sample was comprised of 83 school children (43 girls and 40 boys) of average age 10.15 ± 1.66 years. For the estimation of a MC we used the BOT-2, 2nd version - complete form. Results: The results of our tested group show that the group’s MC is in the lower part of the average level in the area of total motor composite (standard score 46.4±11.8). On average, the weakest performance was recorded in the area of fine manual control. More in-depth analysis showed that the weakest subcomponent of the area of fine manual control was fine motor precision (scale score 10.1±5.5). The group’s most successful area was the component concerning strength and agility. Conclusion: As a pilot study the project indicated that the BOT-2 can be valid for the Czech school children in 4 motor area composites regarding the manual coordination, coordination, strength and agility assessment only. It is not valid for the assessment of fine manual control. In a more detailed analysis of 8 subcategories we observe significantly worse results of Czech children in the area of fine motor precision.

Effects of Combined Resistance Training and Weightlifting on Motor Skill Performance of Adolescent Male Athletes.

Pichardo, AW, Oliver, JL, Harrison, CB, Maulder, PS, Lloyd, RS, and Kandoi, R. Effects of combined resistance training and weightlifting on motor skill performance of adolescent male athletes. J Strength Cond Res 33(12): 3226-3235, 2019-Resistance training and weightlifting are regarded as safe and effective training methods for youth. However, no studies have examined the effects of a year-long resistance training program using weightlifting movements on strength, speed, or power. Therefore, the purpose of this study was to determine the long-term effects of combined resistance training (traditional strength training + plyometrics) with or without weightlifting movements on motor skill performance of adolescent males. Fifty-nine males aged 12-14 years were matched by maturity and allocated to a combined resistance training or a combined resistance training with weightlifting group. Each group completed 28 total weeks of training over an academic year. Pre-, mid- (14 weeks of training), and post-training (28 weeks of training) tests included the resistance training skills battery quotient (RTSQ), absolute isometric midthigh pull peak force (IMTPABS) and ratio-scaled isometric midthigh pull peak force (IMTPREL), countermovement jump, horizontal jump, and 10-, 20-, and 30-m sprint. Repeated-measure analysis of variance revealed that there were no significant between-group responses, but all variables improved significantly within-group. Both groups made small-moderate improvements in RTSQ, IMTPABS, and IMTPREL after the first 14 training weeks (d = 0.45-0.86), whereas small-moderate improvements in lower body power, upper body power, and speed were made after the second 14 training weeks (d = 0.30-0.95). Both groups made small-moderate improvements in all performance variables after 28 weeks of training. These findings highlight the importance of establishing movement competency and strength as a foundation for the subsequent development of power. Furthermore, these findings may help practitioners understand the time course of certain adaptations following a long-term periodized plan for adolescent males.

Physical Literacy and Resilience in Children and Youth.

Background: There is growing interest in the relationship between physical and psychosocial factors related to resilience to better understand the antecedents of health and successful adaptation to challenges in and out of school, and across the lifespan. To further this understanding, a trans-disciplinary approach was used to investigate the association between the multidimensional constructs of physical literacy and resilience in children at a key stage in their development.Methods: Cross-sectional data were collected from 227 school children aged 9-12 years old from five schools in Winnipeg, Manitoba, Canada. Resilience was measured using the Child and Youth Resilience Measure, and physical literacy through the Physical Literacy Assessment for Youth tools. Data were provided by self-report, surrogate assessors of the child (physical education teachers and parents), and trained assessors for movement skills. These data were analyzed using correlation and logistic regression.Results: Resilience was significantly correlated with numerous indicators of physical literacy, including movement capacity, confidence, and competence, environmental engagement, and overall perceptions of physical literacy. Regressions indicated that resilience could be predicted by movement confidence and competence, environmental engagement, and overall physical literacy.Conclusions: The findings of this study, using a constellation of sources, provide foundational evidence for the link between resilience and physical literacy among children, encouraging the importance of physical literacy development in schools. Longitudinal studies are required to further examine this relationship and how these previously unrelated fields may work together for a richer understanding of the interplay between the physical and psychological determinants of well-being.

The Association Between PLAYfun and Physical Activity: A Convergent Validation Study

ABSTRACTPurpose: The purpose of this study was to examine the convergent validity of the PLAYfun tool, a physical literacy-based measure of movement competence, by examining its association with objectively measured physical activity in a sample of children and youth. Method: Participants included 110 children between the ages of seven to 14 years attending a stratified random sample of 27 afterschool programs across the province of Ontario, Canada. The PLAYfun tool was administered to the participants on one occasion at their afterschool program and then they were asked to wear a pedometer for seven consecutive days to measure their physical activity levels. A series of multiple linear regression models were used to examine the association between PLAYfun scores and physical activity, while controlling for age, sex, and time of year (season) in which the data were collected. Results: On its own, the PLAYfun average score accounted for close to 13% of the variance in physical activity, R = .36, R2 = .13, p < .001. The PLAYfun average score was also a significant independent predictor of physical activity, b (SE) = 145.98 (53.46), p < .01, when controlling for age, sex, and season in which the data were collected, R2 = .30, F (4, 105) = 11.04, p < .001. Conclusion: Results from the present study indicate that the PLAYfun tool is a significant predictor of objectively measured physical activity, supporting the convergent validity of the tool.
