This study assessed the convergent validity of the Physical Activity Questionnaire for Adolescents (PAQ-A). The PAQ-A is a modified version for high school students of the Physical Activity Questionnaire for Older Children (PAQC). The PAQ-A is a 7-day recall used to assess general physical activity levels during the school year. Eighty-five high school students in Grades 8 through 12 filled out the PAQ-A and other physical activity measures. The PAQ-A was moderately related to an activity rating (r = .73), the Leisure Time Exercise Questionnaire (r = .57), a Caltrac motion sensor (r = .33), and the 7-day physical activity recall interview (r = .59). The results of this study support the convergent validity of the PAQ-A as a measure of general physical activity level for high school students.

The purpose of this study was to compare the morphological and mechanical properties of the human patellar tendon among elementary school children (prepubertal), junior high school students (pubertal), and adults. Twenty-one elementary school children, 18 junior high school students, and 22 adults participated in this study. The maximal strain, stiffness, Young’s modulus, hysteresis, and cross-sectional area of the patellar tendon were measured using ultrasonography. No significant difference was observed in the relative length (to thigh length) or cross-sectional area (to body mass2/3) of the patellar tendon among the three groups. Stiffness and Young’s modulus were significantly lower in elementary school children than in the other groups, while no significant differences were observed between junior high school students and adults. No significant differences were observed in maximal strain or hysteresis among the three groups. These results suggest that the material property (Young’s modulus) of the patellar tendons of elementary school children was lower than that of the other groups, whereas that of junior high school students was already similar to that of adults. In addition, no significant differences were observed in the extensibility (maximal strain) or viscosity (hysteresis) of the patellar tendon among the three groups.

The purpose of this study was to document the level of physical activity and sedentary behavior in a representative sample of Singaporean adolescents. A random sample of 1,827 secondary school students from six secondary schools (929 boys, 898 girls, mean age 14.9 ± 1.2 yr) completed the Three-Day Physical Activity Recall (3DPAR) self-report instrument. Approximately 63% of Singaporean high school students met current guidelines requiring 60 min of moderate to vigorous physical activity daily. Just over half (51.6%) met the guideline calling for regular vigorous physical activity. Across all grade levels, boys were consistently more active than girls. More than 70% of Singaporean high school students exceeded the recommended 2 hours per day of electronic media use. Collectively, these findings suggest that a significant proportion of Singaporean adolescents are not sufficiently active and are in need of programs to promote physical activity and decrease sedentary behavior.

Few studies have examined high school students’ physical activity habits using objective measures. The purpose of this study was to describe pedometer-determined habitual physical activity levels of youth.
236 high school students (age 12–18 years) wore sealed pedometers for 5 consecutive days. Data were analyzed using generalizing estimating equations.
Mean steps/d (± SE) differed significantly by sex (males, 10,849 ± 381; females, 9652 ± 289), age (junior students [years 9–11], 11,079 ± 330; senior students [years 12 and 13], 9422 ± 334), time of week (weekday, 12,259 ± 287; weekend day, 8241 ± 329), and mode of transportation to and from school (walkers, 13,308 ± 483; car transit users, 10,986 ± 435). Only 14.5% of students achieved at least 10,000 steps on every day during the monitoring period.
Daily step counts differed substantially by age, sex, time of week, and transportation mode to school.

Survey data from 1,071 high school students in a large southern city indicated that high school sports participants were more likely to be sexually active than were nonparticipants. This result was true for both males (66% vs. 52%) and females (52% vs. 36%) and was independent of the sport in which the adolescent participated. This finding suggests that high school teams may provide an opportunity for reaching teenagers in need of sex education counseling.

This study sought to examine whether athletes are more violent, delinquent, or both than their nonathlete classmates. Survey data from 2,436 high school students indicated no significant differences for violent or delinquent behaviors between athletes and nonathletes. However, analysis of the data by the type of sport indicated noncontact sport athletes were less likely to engage in various violent and delinquent behaviors than were contact sport athletes and nonathletes. These relationships were found for both males and females. Noncontact sports may provide some protective effect with regards to violence and delinquency that contact sports do not.

Expectancy beliefs and task values are two essential motivators in physical education. This study was designed to identify the relation between the expectancy-value constructs (Eccles & Wigfield, 1995) and high school students’ physical activity behavior as associated with their energy balance knowledge. High school students (N = 195) in two healthful-living programs (i.e., combination of physical and health education) responded to measures of expectancy-value motivation, energy balance knowledge, in-class physical activity, and after-school physical activity. The structural equation modeling confirmed positive impact from expectancy beliefs and interest value to in-class physical activity (Path coefficient range from .19 to .26, ps < .01). Cost perception was found exerting a negative impact on after-school physical activity but a positive one on lower level of understanding of energy balance (Path coefficient range from -.33 to -.39, ps < .01). The findings painted a complex but meaningful picture about the motivational impact of expectancy-value constructs on physical activity and energy balance knowledge. School healthful-living programs should create motivational environments that strengthen students’ expectancy beliefs and interest value and alleviate their negative perceptions and experiences.
To investigate the reliability of the Achievement Motivation in Physical Education Test (AMPET) and reexamine its factor structure, 10,055 elementary, junior high, and high school students in Japan were tested. The AMPET has seven 8-item subscales consisting of learning strategy (LS), overcoming obstacles (OO), diligence and seriousness (DS), competence of motor ability (CMA), value of learning (VL), anxiety about stress-causing situations (ASCS), and failure anxiety (FA), respectively. The ASCS and FA subscales are associated with negative aspects of the AMPET, while the other five sub-scales are related to positive aspects. The AMPET also contains an 8-item lie scale. The subjects were asked to respond along 5-point Likert rating scales. Item-subscale correlations of the AMPET were sufficiently high. Alpha reliabilities ranged from .797 to .950, and test-retest reliabilities after 5 weeks were .651 to .883. Elementary school pupils showed significantly higher mean scores on the positive aspects of the AMPET than junior high and high school students. The means of female students on the negative aspects of the AMPET were significantly higher than those of male students. Seven factors were extracted from the principal components factor analysis with normal vari-max rotation. Each factor was composed of the seven different subscales of the AMPET.

The purpose of this study was to examine the inter- and intratester reliability of lower extremity circumference measurements obtained by two testers using the same tape measure and two different tape measures. Twenty-one male high school student-athletes participated in this study. Two testers measured lower extremity circumference at three sites using a standard flexible tape measure and a Lufkin tape measure with a Gulick spring-loaded handle attachment. Measurement sites were medial joint line, 20 cm above medial joint line, and 15 cm below medial joint line. Intraclass correlation coefficients were computed for inter- and intratester comparisons for each measuring device and each measurement site. Results indicated high reliability but a significant difference between the two tape measures. These findings indicate that the reliability of lower extremity circumference measurements is not influenced by tester experience and that the Lufkin tape measure with the Gulick handle attachment is the more accurate of the two tape measures.
