Ren, Sicong; Chen, Zezhao; Qin, Xiong; Zhao, Xiaochen; Yang, Tim D.; Zhu, Weimo – Measurement in Physical Education and Exercise Science, 2021
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…

Carazo-Vargas, Pedro; Salazar-Obando, Joshua; Vargas-Montero, Andrea; Alvarado-Barrantes, Ricardo; Siles-Canales, Francisco; Moncada-Jiménez, José – Measurement in Physical Education and Exercise Science, 2020
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…

Stanton, Robert; Doering, Thomas M.; Macgregor, Campbell; Borges, Nattai; Delvecchio, Luke – Measurement in Physical Education and Exercise Science, 2019
Countermovement jump (CMJ) height is an important parameter in physical performance. This study compared CMJ height measured using ChronoJump contact mat (CJ) and Myotest accelerometer (MT) systems with a force platform (FP). Thirty recreationally active adults (32.1 ± 10.4 years, 75.9 ± 12.0 kg, 173.2 ± 6.3 cm) completed a CMJ protocol where…

Callaway, Andrew J.; Cobb, Jon E. – Measurement in Physical Education and Exercise Science, 2012
Where as video cameras are a reliable and established technology for the measurement of kinematic parameters, accelerometers are increasingly being employed for this type of measurement due to their ease of use, performance, and comparatively low cost. However, the majority of accelerometer-based studies involve a single channel due to the…

Harrison, Andrew J.; Jensen, Randall L.; Donoghue, Orna – Measurement in Physical Education and Exercise Science, 2005
The reliability of a laser system was compared with the reliability of a video-based kinematic analysis in measuring displacement and velocity during running. Validity and reliability of the laser on static measures was also assessed at distances between 10 m and 70 m by evaluating the coefficient of variation and intraclass correlation…

Garcia, Anne W.; Langenthal, Carla R.; Angulo-Barroso, Rosa M.; Gross, M. Melissa – Measurement in Physical Education and Exercise Science, 2004
In this pilot study of 16 children, we evaluated the reliability and validity of three accelerometers (Mini-Motionlogger [MML], Computer Science Applications, Inc. Actigraph [CSA], and BioTrainer) as indicators of energy expenditure and vertical ground reaction force. The children wore 2 of each type of monitor while they walked, ran, and…
