Laurson, Kelly R.; Baptista, Fátima; Mahar, Matthew T.; Welk, Greg J.; Janz, Kathleen F. – Measurement in Physical Education and Exercise Science, 2022
We developed plank test standards, based on trunk lean mass-to-fat mass (LM/FM) ratio, in a sample of healthy Portuguese 10--18 year olds (n = 474, 46.4% female). Height and weight were measured and muscular endurance was assessed using the prone plank test. Trunk LM/FM ratio was determined using dual-energy x-ray absorptiometry. Plank standards…

Baptista, Fátima; Zymbal, Vera; Janz, Kathleen F. – Measurement in Physical Education and Exercise Science, 2022
This study examined the predictive validity of musculoskeletal fitness tests for identifying sarcopenia in youth. The sample was 529 participants age 10 to 18 years. Indices included: total lean body mass (LBM) normalized for height (LBM index, LBMI, kg/m2), appendicular LBMI (aLBMI, kg/m[superscript 2]), and LBM to fat body mass (FBM) ratio…

Peralta, Miguel; Gouveia, Élvio Rúbio; Ferrari, Gerson; Catunda, Ricardo; Heriques-Neto, Duarte; Marques, Adilson – Journal of Teaching in Physical Education, 2023
Purpose: Physical education (PE) is an important context for promoting health-related cardiorespiratory fitness (CRF) in youth. Within PE, the lesson context and teacher behavior may be relevant for the promotion CRF; however, evidence is scarce. Therefore, the purpose of this study was to assess whether students' CRF improvement in a school year…
