Cicone, Zackary S.; Holmes, Clifton J.; Fedewa, Michael V.; MacDonald, Hayley V.; Esco, Michael R. – Research Quarterly for Exercise and Sport, 2019
Purpose: Maximal heart rate (MHR) is an important physiologic tool for prescribing and monitoring exercise in both clinical and athletic settings. However, prediction equations developed in adults may have limited accuracy in youth. The purpose of this study was to systematically review and analyze the available evidence regarding the validity of…

Santos, Sara; Coutinho, Diogo; Gonçalves, Bruno; Schöllhorn, Wolfgang; Sampaio, Jaime; Leite, Nuno – Research Quarterly for Exercise and Sport, 2018
Purpose: The aim of this study was to identify the effects of a differential-learning program, embedded in small-sided games, on the creative and tactical behavior of youth soccer players. Forty players from under-13 (U13) and under-15 (U15) were allocated into control and experimental groups and were tested using a randomized pretest to posttest…

Finn, Kevin J.; Saint-Maurice, Pedro F.; Karsai, István; Ihász, Ferenc; Csányi, Tamás – Research Quarterly for Exercise and Sport, 2015
Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4-17.9 years) completed testing during a single session. Each measure provided percent body fat (%BF), while the InBody 720 included fat-free mass (FFM). The validity was examined…

Faigenbaum, Avery D.; Best, Thomas M.; MacDonald, James; Myer, Gregory D.; Stracciolini, Andrea – Research Quarterly for Exercise and Sport, 2014
Exercise deficit disorder (EDD) is a pediatric medical condition characterized by reduced levels of moderate-to-vigorous physical activity (MVPA) that are below current recommendations and inconsistent with positive health outcomes. At present, a majority of children and adolescents meet the diagnostic criteria for EDD because they are not…

Rothenberg-Cunningham, Alek; Newell, Karl M. – Research Quarterly for Exercise and Sport, 2013
Purpose: This study investigated the age-related speed--accuracy strategies of children, adolescents, and adults in performing a rapid striking task that allowed the self-selection of the interception position in a virtual, two-dimensional environment. Method: The moving target had curvilinear trajectories that were determined by combinations of…

Hancock, David J.; Ste-Marie, Diane M.; Young, Bradley W. – Research Quarterly for Exercise and Sport, 2013
Relative age effects (RAEs; when relatively older children possess participation and performance advantages over relatively younger children) are frequent in male team sports. One possible explanation is that coaches select players based on physical attributes, which are more likely witnessed in relatively older athletes. Purpose: To determine if…

Busquets, Albert; Marina, Michel; Angulo-Barroso, Rosa – Research Quarterly for Exercise and Sport, 2013
Purpose: Improvements in motor performance and coordination may be impacted by the interaction of practice and organismic constraints. It has been proposed that these aspects of motor learning are achieved at a different time rate: first, during placement of the events (performance), and second, segmental spatiotemporal relationships…

Zhuang, Jie; Chen, Peijie; Wang, Chao; Huang, Liang; Zhu, Zheng; Zhang, Wenjie; Fan, Xiang – Research Quarterly for Exercise and Sport, 2013
Purpose: The purpose of this study was to investigate the characteristics of missing physical activity (PA) data of children and youth. Method: PA data from the Chinese City Children and Youth Physical Activity Study ("N" = 2,758; 1,438 boys and 1,320 girls; aged 9-17 years old) were used for the study. After the data were sorted by the…

Liu, Ting; Jensen, Jody L. – Research Quarterly for Exercise and Sport, 2012
Bilateral asymmetry, a form of limb laterality in the context of moving two limbs, emerges in childhood. Children and adults show lateral preference in tasks that involve the upper and lower limbs. The importance of research in limb laterality is the insight it could provide about lateralized functions of the cerebral hemispheres. Analyzing…

Goh, Hui-Ting; Kantak, Shailesh S.; Sullivan, Katherine J. – Research Quarterly for Exercise and Sport, 2012
Reduced feedback during practice has been shown to be detrimental to movement accuracy in children but not in young adults. We hypothesized that the reduced accuracy is attributable to reduced movement parameter learning, but not pattern learning, in children. A rapid arm movement task that required the acquisition of a motor pattern scaled to…

Okazaki, Fabio H. A.; Keller, Birgit; Fontana, Fabio E.; Gallagher, Jere D. – Research Quarterly for Exercise and Sport, 2011
In sports, the relative age effect (RAE) refers to performance disadvantages of children born late in the competition year compared to those with birthdays soon after the cutoff date. This effect is derived from age grouping, a strategy commonly used in youth sport programs. The purpose of age grouping is to decrease possible cognitive, physical,…

Salmon, Jo; Timperio, Anna; Chu, Binh; Veitch, Jenny – Research Quarterly for Exercise and Sport, 2010
This study aimed to determine cross-sectional associations of dog ownership, dog walking, and physical activity (PA) among children and their parents. Objective measures of PA were obtained for children ages 5-6 and 10-12 years from 19 primary schools across Melbourne, Australia. Parents self-reported their PA, dog ownership, and frequency of dog…

Barnett, Lisa M.; van Beurden, Eric; Morgan, Philip J.; Brooks, Lyndon O.; Beard, John R. – Research Quarterly for Exercise and Sport, 2010
Students' proficiency in three object control and three locomotor skills were assessed in 2000 (M age = 10.06 years, SD = 0.63) in New South Wales, Australia and in 2006-07 (M age = 16.44 years, SD = 0.64). In 2006-07, 266 students, 138 girls (51.9%) and 128 boys (48.1%), had at least one skill reassessed. Boys were more object control proficient…

Lantero, Dawn A.; Ringenbach, Shannon D. – Research Quarterly for Exercise and Sport, 2009
Children ages 4, 6, and 8 years and adults performed self-selected, continuous, unimanual and bimanual coordination tasks for 30 s. The length of time performing the task was investigated as a potential control parameter. As hypothesized, all groups spent less time in antiphase than in in-phase coordination as the trial continued. These results…

Southard, Dan – Research Quarterly for Exercise and Sport, 2009
Accomplished throwers conserve angular momentum when distal joints of the throwing arm reach peak velocity at a later time than their proximal neighbors. The result is an increase in velocity of the most distal segment--the hand. Past research indicates that skill level varies by the number of joints experiencing distal timing lag (time to peak…
