Huaijin Xu; Weimo Zhu; Xiong Qin; Zezhao Chen; Xiaotian Gao – Measurement in Physical Education and Exercise Science, 2024
Using the 2017-2018 National Health and Nutrition Examination Survey (weighted population size = 35,460,209; 8-18 years old; 52.1% males), we compared the obesity prevalence in children and adolescents between body mass index-based (BMI-based) and total percent body fat-based (BF%-based, measured by the dual-energy x-ray absorptiometry) cutoffs.…

Long Jump, Vertical Jump, and Vertical Jump Power Reference Curves for 10-18 Year Olds
Peer reviewed Peer reviewed

Laurson, Kelly R.; Baptista, Fátima; Mahar, Matthew T.; Welk, Greg J.; Janz, Kathleen F. – Measurement in Physical Education and Exercise Science, 2022
We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…

Linking Vertical Jump and Standing Broad Jump Tests: A Testing Equating Application
Peer reviewed Peer reviewed
Direct linkDirect link
Zhu, Weimo; Konishi, Daniel; Welk, Gregory; Mahar, Matthew; Laurson, Kelly; Janz, Kathleen; Baptista, Fatima – Measurement in Physical Education and Exercise Science, 2022
This study evaluated test-equating methods to enable comparisons and conversions between the vertical jump (VJ) and standing long jump (SLJ) tests. A total of 528 youth (280 males) performed VJ and SLJ, and their scores were randomly split as the calibration (C) sample (n = 478) and cross-validation (CV) sample (n = 50). SLJ scores of the C sample…

Tracking of Physical Fitness Components from Childhood to Adolescence: A Longitudinal Study
Peer reviewed Peer reviewed

True, Larissa; Martin, E. M.; Pfeiffer, K. A.; Siegel, S. R.; Branta, C. F.; Haubenstricker, J.; Seefeldt, V. – Measurement in Physical Education and Exercise Science, 2021
Childhood physical fitness relative to adult health outcomes coupled with scant longitudinal research indicates that tracking of fitness components throughout childhood/adolescence is imperative. The study examined the stability/tracking of 9 measures of fitness for boys and girls at 5 points throughout childhood/adolescence. Tracking coefficients…

Estimation of Lower Body Muscle Power from Vertical Jump in Youth
Peer reviewed Peer reviewed

Mahar, Matthew T.; Welk, Gregory J.; Janz, Kathleen F.; Laurson, Kelly; Zhu, Weimo; Baptista, Fatima – Measurement in Physical Education and Exercise Science, 2022
Incorporation of the vertical jump (VJ) test in health-related fitness batteries is predicated on the availability of prediction equations to accurately estimate VJ power. The purpose was to develop and validate a generalizable equation to estimate VJ power from VJ height, body mass, age, and sex in 10- to 18-year-olds. The sample (N = 529)…

Sansano-Nadal, Oriol; Wilson, Jason J.; Martín-Borràs, Carme; Brønd, Jan Christian; Skjødt, Mathias; Caserotti, Paolo; Roqué I. Figuls, Marta; Blackburn, Nicole E.; Klenk, Jochen; Rothenbacher, Dietrich; Guerra-Balic, Myriam; Font-Farré, Manel; Denkinger, Michael; Coll-Planas, Laura; Deidda, Manuela; McIntosh, Emma; Giné-Garriga, Maria; Tully, Mark A. – Measurement in Physical Education and Exercise Science, 2022
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…

Predictive Ability of the Medicine Ball Chest Throw and Vertical Jump Tests for Determining Muscular Strength and Power in Adolescents
Peer reviewed Peer reviewed
Direct linkDirect link
Hackett, Daniel A.; Davies, Timothy B.; Ibel, Denis; Cobley, Stephen; Sanders, Ross – Measurement in Physical Education and Exercise Science, 2018
This study examined the predictive ability of the medicine ball chest throw and vertical jump for muscular strength and power in adolescents. One hundred and ninety adolescents participated in this study. Participants performed trials of the medicine ball chest throw and vertical jump, with vertical jump peak power calculated via an estimation…

Fernandez-Santos, Jorge R.; Gonzalez-Montesinos, Jose Luis; Ruiz, Jonatan R.; Jiménez-Pavón, David; Castro-Piñero, Jose – Measurement in Physical Education and Exercise Science, 2018
The purpose of this study was to analyze the kinematic variables that determine the performance of the standing long jump in children 6- to 12-years-old. There were 121 healthy children (58 girls) recorded while they performed the standing long jump test. All kinematic variables showed a significant correlation with calculated jump distance and…

Arbour-Nicitopoulos, Kelly P.; Faulkner, Guy E.; Leatherdale, Scott T. – Measurement in Physical Education and Exercise Science, 2010
The objective of this study was to examine the pattern of relations between missing weight and height (BMI) data and a range of demographic, physical activity, sedentary behavior, and academic measures in a young sample of elementary school children. A secondary analysis of a large cross-sectional study, PLAY-On, was conducted using self-reported…
