The Relationship Between Barrier Self-Efficacy and Physical Activity in Children and Adolescents: A Meta-Analysis

Christopher R. Hill, Deborah L. Feltz, Stephen Samendinger, and Karin A. Pfeiffer

health risks highlight the importance of examining variables that could effect increases in childhood PA. The influence of one’s self-efficacy beliefs to overcome barriers shows promise in the physical domain as a common positive correlate with adolescent PA ( Bauman et al., 2012 , Craggs, Corder, van

“I Do What I Like”: 8- to 10-Year-Old Children’s Physical Activity Behavior Is Already Interrelated With Their Automatic Affective Processes

results in energy expenditure” ( Caspersen et al., 1985 , p. 126), whereas exercise forms a subcategory of PA. The negative consequences of physical inactivity during childhood can be far reaching. PA has short-term positive effects on children’s health (e.g., bone and mental health; Biddle et al., 2019

Temperament and Physical Activity in Childhood

MinKyoung Song, Robert F. Corwyn, Robert H. Bradley, and Julie C. Lumeng

Childhood obesity continues to be an epidemic. 1 , 2 Given that low levels of physical activity increase the risk for obesity, 3 , 4 the importance of physical activity among youth cannot be overemphasized. 5 , 6 Unfortunately, despite increased efforts to promote physical activity levels by

Nature-Based Early Childhood Education and Children’s Physical Activity, Sedentary Behavior, Motor Competence, and Other Physical Health Outcomes: A Mixed-Methods Systematic Review

Avril Johnstone, Paul McCrorie, Rita Cordovil, Ingunn Fjørtoft, Susanna Iivonen, Boris Jidovtseff, Frederico Lopes, John J. Reilly, Hilary Thomson, Valerie Wells, and Anne Martin

Traditional Early Childhood Education (ECE) is typically characterized by predominately man-made structures, such as swings, climbing frames, and slides in the playground with very few natural features integrated. 1 Children who attend traditional ECE spend only a small amount of their time

Bidirectional Associations Between Adiposity, Sedentary Behavior, and Physical Activity: A Longitudinal Study in Children

Chiaki Tanaka, Xanne Janssen, Mark Pearce, Kathryn Parkinson, Laura Basterfield, Ashley Adamson, and John J. Reilly

Childhood obesity is a widespread health and social problem that is still increasing in prevalence in many countries. 1 A previous review of prospective studies concluded that low levels of baseline physical activity (PA) were only weakly or not at all associated with body fat gain. 2 More recent

). There is now consistent evidence showing that adequate levels of GMC are not only positively related to children’s health trajectories ( 49 ), but also to positive engagement in moderate to vigorous physical activity ( 15 , 24 ). It has also been reported that GMC levels in childhood and adolescence are

Sex-Related Differences in Scapular Kinematics During Elevation of the Arm in Asymptomatic Children and Adults

Fernanda Assis Paes Habechian, Dayana Patricia Rosa, Melina Nevoeiro Haik, and Paula Rezende Camargo

Recently, it has been suggested that sex may influence scapular kinematics. A more comprehensive analysis of the scapular kinematics in children and adults, including sex as a factor, will help to understand if differences between sexes are present since childhood. The purpose of this study was to compare scapular kinematics between sex in children and adults during elevation of the arm. One-hundred and sixteen asymptomatic adults (58 men and 58 women) and 53 children (28 boys and 25 girls) participated in the study. Three-dimensional scapular kinematics during elevation of the arm were obtained using an electromagnetic tracking device. Women had a more upwardly rotated scapula in the nondominant side (P < .05), with large effects and a more anteriorly tilted position at 60°, 90°, and 120° of arm elevation in the dominant side, and at 90° and 120° in the nondominant side (P < .05) with moderate effects when compared with men. Differences between sexes were not found in the children (P > .05). In conclusion, sex seems to influence scapular kinematics in adulthood, but not in childhood.

Exercise for Bone in Childhood—Hitting the Sweet Spot

Belinda R. Beck

Puberty ensues when marked alterations in circulating hormones in childhood stimulate dramatic physical and physiological transformations. It is, therefore, small wonder that the body can be observed to respond differently to certain stimuli according to the timing of the provocation in relation to
