This study examined the within- and between-day variability of time-segmented sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) in adolescents. The sample comprised 154 adolescents (11-16 years old) from two public schools in Florianópolis, Brazil. The proportion of time spent in SB, LPA, and…

This study summarized protocols in the "Lisbon Study for the Development and Evaluation of Musculoskeletal Fitness Standards in Youth" and assessed associations between fitness assessments and health outcomes. The sample was 529 children and adolescents (10 to 18 yr). The fitness assessments included handgrip, vertical jump, long jump,…

The purpose of this study was to develop the Youth Physical Activity Attitude Scale (YPAAS). Questions were developed using dual-component (affective-cognitive, positive-negative) beliefs framework. Content validity was established with expert panel review. Two samples of 4th-8th grade students (51% Female; 9-14 years) completed the YPAAS (sample…

Research tracking sport participation from youth to adulthood is relatively rare, as is research that tracks youth sport participation with regard to adult physical activity (PA) levels, especially in the United States. Aims of this study were: 1) To investigate the degree to which sport participation tracked across youth, adolescence, and early…

Although students' perceived learning is central in physical education (PE), few measurements are available. Furthermore, little is known about how students' perceptions of PE effect students' perceived learning in PE. Therefore, the aim was to develop a scale to assess students' perceived learning and a measurement to assess students' perceived…

The objective of this study was to evaluate gross motor competence and growth spurt in Canadian youth. Eighty-two children (38 boys, 44 girls) were assessed over a time period of five years. Growth rate was measured quarterly; motor competence was evaluated once per year using the Bruininks-Oseretsky Test of Motor Proficiency. Peak height velocity…

Interpreting change in Body mass index (BMI) among youth by comparison to growth charts can be difficult because of maturation-related changes. The aim of this paper was to evaluate the utility of several alternative methods for assessing change in BMI among children. Participants included 1,615 children measured for stature and body mass in first…

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined…

The current article provides an important insight into measurement differences between two commonly used self-reports and accelerometer-determined moderate to vigorous physical activity (MVPA) scores within matched samples across 1 school year. Participants were 998 fifth- through eighth-grade students who completed self-reports and 76 fifth- and…

Fundamental movement skills (FMS) competence is low in adolescent girls. An assessment tool for teachers is needed to monitor FMS in this demographic. The present study explored whether the Canadian Agility and Movement Skill Assessment (CAMSA) is feasible for use by physical education (PE) teachers of Australian Year 7 girls in a school setting.…

This study presents the development process and initial validation of the NyTid test, a process-oriented movement assessment tool for compulsory school pupils. A sample of 1,260 (627 girls and 633 boys; mean age of 14.39) Swedish school children participated in the study. In the first step, exploratory factor analyses (EFAs) were performed in…

This study aimed to examine the validity and reliability of an instrument designed to measure student perceptions of curricular goals in physical education, the Curricular Goals in Physical Education Questionnaire. Participants were 879 Finnish students from grades 7 to 9 (412 girls, 467 boys; mean age 13.81). An exploratory factor analysis was…

The Centers for Disease Control have suggested that physical education plays a role in promoting healthy lifestyles. Prior research suggests a link between attitudes toward physical education and physical activity outside school. The current study provides additional evidence of construct validity through a validation across two instruments…

The study of teacher/coach role conflict has a long history in the physical education literature. However, only a few studies have measured the construct using psychometric instrumentation. Ryan (2008) created one such instrument, but the survey was not validated prior to use. As such, the purpose of this investigation was to evaluate the…
