ABSTRACT The purpose of this manuscript is to provide a summary of Measurement in Physical Education and Exercise Science (MPEES)-related activities in 2020. In 2020 original submissions (i.e., not counting revised manuscripts) increased by ~84% as compared to 2019. Fifty-three countries were represented across the 386 original manuscripts submitted to MPEES in 2020. MPEES continues to welcome high-quality

ABSTRACT Evidence suggests that children struggle to acquire age-appropriate fundamental movement skills (FMS), despite their importance for facilitating physical activity. This has led to calls for routine school-based screening of children’s FMS. However, there is limited research exploring schools’ capacity to conduct such assessments. This study investigated what factors might affect the adoption

ABSTRACT The objective was to assess the psychometric properties of a French-Canadian version of the third edition of the Test of Gross Motor Development (TGMD-3). Participants were 127 French-speaking Canadian children. Results supported the validity-reliability of a bifactor exploratory structural equation modeling representation of the TGMD-3. Additionally, results supported a lack of differential

ABSTRACT The aim of this study was to examine the trends in Olympic Games (OLY) and World Long Course Championships (WLC) across three performance categories (1st-3rd, 4th-8th and 9th-16th), and to make predictions for the 2024 OLY. Top 16 rankings were obtained for all OLY and WLC competitions between 2011 and 2019. Linear regression and forecasting models were used to examine trends and predictions

ABSTRACT This study expanded the State Mindfulness Scale for Physical Activity (SMS-PA) to include acceptance items to better represent core elements of mindfulness. Young adults who just participated in physical activity (N = 394) completed a survey to assess state mindfulness and theoretically relevant constructs about affect, motivation, and body image. An exploratory factor analysis was used to

ABSTRACT Falls are a significant medical and economical concern worldwide. Younger individuals with visual impairment (VI) may be more susceptible to falling and fall-related injuries when compared to peers without a VI. Self-perceived balance confidence is a psychological construct that may predict and/or mediate fall- or other health-related outcomes in youth with VI. However, extensive psychometric

ABSTRACT This study aimed to determine the validity of the ActiGraph wGT3X-BT for step counts (SC) at five different body locations in laboratory settings. A total of 29 male adults participated in this study. The participants walked or ran for different speeds on the treadmill while wearing ActiGraph wGT3X-BT on their right wrist (RW), left wrist (LW), waist, right ankle (RA), and right upper arm

ABSTRACT This research developed and psychometrically tested the Sport Education Scale, a measure of students’ perceptions of the structural features of a Sport Education season. In the first study (N = 277 students), a pool of 28 items was developed, and an exploratory factor analysis found a 7-factor solution. In the second study (N = 656 students), a confirmatory factor analysis verified the 28-item

Twenty participants wore four accelerometers (Axivity, ActiGraph, activPAL, GENEActiv) for three free-living days. Postural and physical activity outputs (average acceleration, intensity gradient, intensity of

ABSTRACT We aimed to assess the test-retest reliability of five muscle strength and physical function tests in healthy children. Forty-one children (6–9 years) were tested three times 4–10 days apart. The test protocol included maximal isometric leg press, hand grip strength, squat jump, long jump, and a 30-sec sit-to-stand test (STST). When comparing test round 1 with 2 and 2 with 3, we found good-to-excellent

ABSTRACT This study examined the concurrent validity of a tummy time questionnaire and time-use diary against an accelerometer measure. Participants were 29 parents and their 6-month-old infants from the Early Movers project in Edmonton, Canada. Tummy time was concurrently measured using a parental questionnaire, a time-use diary, and a validated GENEActiv accelerometer. In participants with data on

ABSTRACT We examined the relationships between heights of different vertical jumps and isometric single-joint strength characteristics of ankle, knee, hip, and trunk joints in young male soccer players (n = 117). The highest peak torque and rate of torque development (RTD) outcomes were in low to moderate correlation with jump heights (r = 0.25–0.50). The correlations were generally higher for bilateral

ABSTRACT The main aim of this study was to assess the criterion validity of the Sedentary Behavior Questionnaire (SBQ) to measure SB in community-dwelling older adults using thigh-measured accelerometry as the criterion method. 801 participants (75.6 ± 6.1 years old, 57.6% females) provided valid thigh-based accelerometer data (activPAL/Axivity) and completed the SBQ. Criterion validity was assessed

ABSTRACT This study examined the associations of parental movement behaviors (MBs; sleep, stationary time, light-intensity physical activity [LPA], and moderate- to vigorous-intensity physical activity [MVPA]) and parent–child proximity with preschool-aged children’s MBs. Parent–child MBs and proximity were assessed with Bluetooth-enabled accelerometers. Parent–child proximity behaviors were categorized

ABSTRACT Inconsistent filtering of force plate data persists in published studies. Previous evidence suggests that low pass filtering produces the largest error when calculating jump height, but used jump height from unfiltered force plate data as the criterion. This study investigated the effects of low pass filtering on jump height calculated from force plate data, using jump height recorded from

ABSTRACT The 2-minute step test (2MST) requires minimal resources and is valid in adults older than 60 years. Here we investigate if the 2MST can be used to estimate peak oxygen consumption (VO2peak) in healthy middle-aged adults (40–59 years old). Thirty-six participants completed the 2MST and a maximal graded treadmill test with breath-by-breath gas analysis. Outcome measures included the number

ABSTRACT The purpose of this study was to compare activPAL algorithm-estimated values for time in bed (TIB), wake time (WT) and bedtime (BT) against self-report and an algorithm developed by van der Berg and colleagues. Secondary analyses of baseline data from the Community Activity for Prevention Study (CAPs) were used in which adults ≥ 18 years wore the activPAL for seven days. Mixed-effects models

ABSTRACT There are two schools of thought in statistical analysis, frequentist, and Bayesian. Though the two approaches produce similar estimations and predictions in large-sample studies, their interpretations are different. Bland Altman analysis is a statistical method that is widely used for comparing two methods of measurement. It was originally proposed under a frequentist framework, and it has

ABSTRACT The purpose of this study is to identify the effect of a tailored domain-specific intervention using contextual information about sedentary behavior to reduce sedentary time. A total of 40 participants (i.e., general adults) were randomly assigned to three groups (i.e., tailored domain-specific intervention, standard intervention and control). Behavioral strategies included educational meeting

ABSTRACT The purpose of this study was to overview recent bone loading measurements in physical activity, determine their validity and reliability, and recommend future research directions. A systematic search in three major databases was performed using combinations from a set of keywords, and the identified studies were selected using predetermined criteria. The final review included 29 bone loading

ABSTRACT Obesity has been found to relate to urine-assessed hypohydration risk at the population level, but studies have often failed to account for lean mass, which influences urine solute load. Adults (n = 8,699) from the National Health and Nutrition Examination Survey were categorized as hypohydrated or not using five urine-based methods. Hypohydration rates varied widely between the methodologies

ABSTRACT The purpose of this study was to develop the Youth Physical Activity Attitude Scale (YPAAS). Questions were developed using dual-component (affective-cognitive, positive-negative) beliefs framework. Content validity was established with expert panel review. Two samples of 4th–8th grade students (51% Female; 9–14 years) completed the YPAAS (sample 1, n= 3,188; sample 2n= 679). Exploratory and

ABSTRACT The International Physical Activity Questionnaire – Short Form (IPAQ-SF) is a globally-used self-report measure of physical activity (PA). Validity evidence exists; none has evaluated the IPAQ-SF with reduced recall time. This study evaluates absolute and relative agreement for PA at all intensities, and relative to recommended guideline classification through: (1) a daily, online-delivered

ABSTRACT Body composition (BC) is a valuable indicator of health and performance. Air-displacement plethysmography (ADP) is a popular, efficient, and reliable method for assessing BC. A-mode ultrasonography (AUS) is another method, and its affordability, mobility, and practicality make it a plausible device for industry and health professionals. This study assessed the cross-sectional and change relationships

ABSTRACT This study evaluated the estimated jump height (JH) differences between an inertial measurement unit (IMU), a linear position transducer (LPT), and two force plates (FPs). Thirty-eight student-athletes were recruited to perform vertical jumps that were simultaneously recorded using two dual-axis FPs (criterion measure), an LPT and an IMU. Very large and almost perfect linear relationships

ABSTRACT The aim of the present study was to investigate a think aloud protocol as a novel way to measure indicators of self-control during acts of physical persistence. Using a within-person design, 35 participants (9 males, 26 females) completed two wall-sit persistence tasks, one employing a think aloud protocol, and the other silent. A two-way mixed ANOVA found no significant differences in persistence

ABSTRACT Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the strength measurement of knee and hip muscles and their ratios. Thirty-five recreational athletes completed quadriceps, hamstring, and hip adductors and abductors strength tests in two identical

ABSTRACT The aim of the study was to determine the convergent validity of a portable polysomnograph and an accelerometer for measuring sleep efficiency and movement in college students. Volunteers were 29 healthy students (males = 15, females = 14) who simultaneously wore the Nox T3 portable polysomnograph and the ActiGraph wGT3X-BT accelerometer. Both devices recorded x, y, and z coordinates at 10 Hz

ABSTRACT Previous activity classification studies have typically been performed on normal weight individuals. Therefore, it is unclear whether a generic classification algorithm could be developed that would perform consistently across individuals who fall within different BMI categories. Acceleration data were collected from the hip and ankle joints of 50 individuals: 17 normal weight, 14 overweight

ABSTRACT A good fitness testing program can promote physical activity and fitness. There is no published research, however, that has examined the relationships between teachers’ attitudes and students’ performance on fitness tests. This study investigated the attitudes of urban middle school physical education teachers (N = 74) toward physical fitness tests and their relationship with student performance

ABSTRACT Excess adipose tissue may impact the motor performance of youth. Therefore, the current study examined (a) if adiposityinfluenced performance in the jump and reach and 30-yard dash and (b) if maturation predicted motor performance. Participants (N = 267) included girls aged 8 to 16 years. Latent growth curves were used to assess changes in motor performance. Sum of skinfolds predicted jump

ABSTRACT The Michigan State University Motor Performance Study (MPS) was initiated in 1967 and lasted 32 years. Three central components existed: 1) Educational component, in which students experienced applied work with youth; 2) Instructional component, whereby enrolled youth received sport-specific skill instruction; and 3) Research component. The primary goals of the research component of the MPS

ABSTRACT Free-living comparability of wGT3X-BT and GT9X ActiGraphs has not been verified. Participants (n = 34, 35% females, 7–17 y) wore hip-worn monitors for one week. Vector magnitude (VM; 15-s epoch), Mean Amplitude Deviation (MAD) and Euclidean Norm Minus One (ENMO) (5-s epoch), and percent of time spent in each activity intensity (using cut-points) were calculated. At the epoch-level, correlations

ABSTRACT Sexual maturation is one method by which researchers account for developmental timing during growth. In a longitudinal motor performance study (MPS), mothers reported their own recalled age at menarche and their daughters.’ Approximately twenty years later, a sample of those daughters provided their recalled age at menarche. Study purposes were to determine whether: 1) average age at menarche

ABSTRACT Psychological flexibility (PF), teaching resiliency (tRES), and sense of purpose (SOP) are characteristics that influence physical education teaching sustainability. The study's purpose was to validate an instrument measuring PF, tRES, and SOP relative to teachers’ intent to remain teaching (IRT) in high poverty (>60% low-income) schools and evaluate latent variable relationships. A 22-item

ABSTRACT The purpose of this study was to determine the validity and reliability of the Power Walker® 610(PW) pedometer for step counting in children. The study sample was composed of 30 boys and 22 girls, from 8–13 years old.
