The relationship between physical fitness and academic achievement has received much attention owing to the increasing prevalence of children who are overweight and unfit, as well as the inescapable pressure on schools to produce students who meet academic standards. This study examined 259 public school students in third and fifth grades and found that field tests of physical fitness were positively related to academic achievement. Specifically, aerobic capacity was positively associated with achievement, whereas BMI was inversely related. Associations were demonstrated in total academic achievement, mathematics achievement, and reading achievement, thus suggesting that aspects of physical fitness may be globally related to academic performance in preadolescents. The findings are discussed with regards to maximizing school performance and the implications for educational policies.

Concern over academic integrity in recent years has led the NCAA to establish eligibility standards for incoming student-athletes. This has stirred controversy because of the differential effects of the use of standardized test scores on black versus white student-athletes. The present study examines race differences in the predictors of college grade point average (GPA) for student-athletes participating in revenue producing sports. The findings suggest there are different predictors of college academic achievement for black versus white student-athletes. High school GPA and mother’s occupation are the only significant predictors of college GPA for black student-athletes. On the other hand, high school GPA, socioeconomic status, and SAT/ACT scores were significant predictors for white student-athletes. The results are discussed in light of the need for future investigations into the predictors of academic performance of student-athletes as well as current and future NCAA policy

The Standardized Test Method for Shock-Absorbing Properties of Playing Surface Systems and Materials (ASTM F-355) was used to evaluate the shock absorbing characteristics of 13 floors used for dance exercise. Acceleration-time histories indicated that the floors differed markedly in their shock absorbing behavior. The complex nature of the acceleration-time histories led to the conclusion that descriptors that have previously been used to quantify shock absorbing data were inadequate for the floors examined in this investigation. An additional procedure was devised in order to examine potentially injurious stresses on a performer while executing a common dance exercise movement performed on each of the 13 floors tested. It was concluded that the two testing procedures evaluated differing aspects of the shock absorbing mechanisms involved in dance exercise. However, a tentative relationship between the two corresponding data sets provided some support for the retention of ASTM F-355 as a reproducible test for the shock absorbing characteristics of floors.

This paper explains the failure of an obesity intervention funded by a Carol M. White U.S. Department of Education grant which created a three way partnership between middle schools in a poor largely Latino school district, the local University, and local after-school care providers. This paper assesses the project and situates it theoretically using Foucault’s microphysics of power and Bourdieu’s concepts of capital to analyze the refusal of most students and teachers to engage in the program and the standardized testing required by the state. We further articulate a new form of Bourdieu’s concept of symbolic violence based on position in the consumer hierarchy. We conclude with a critique of grant mechanisms as a means of addressing health issues, and situate the obesity epidemic as a social construction that perpetuates inequality and discourses of power.

Although research on the psychological correlates of ocean surfing is scarce, substantial anecdotal evidence suggests that the sport offers a uniquely positive experience. Prior research has demonstrated that surfers report fewer symptoms of depression and anxiety than normative groups, but no explanation has been identified. Greater spirituality has been correlated with lower depression and anxiety, and many surfers have described surfing as a spiritual experience, indicating a potential connection. One hundred surfers were recruited from the Hawaiian Islands and the mid-Atlantic region of the United States. Participants reported their surfing habits and levels of their spiritual surfing experiences. Standardized tests were used to measure participants’ spirituality, depression, and anxiety levels. Results indicated that surfers reported fewer symptoms of depression and anxiety than most available normative groups. Results also demonstrated that greater spirituality is associated with less depression and more spiritual surfing experiences.

This paper provides an overview of practical methods for assessing body composition of children, adults, and older adults. Three methods commonly used in field and clinical settings are skinfolds, bioelectrical impedance analysis, and anthropometry. For each method, standardized testing procedures, sources of measurement error, recommendations for technicians, and selected prediction equations for each age category are presented. The skinfold method is appropriate for estimating body fat of children (6–17 years) and body density of adults (18–60 years) from diverse ethnic groups. Likewise, bioimpedance is well suited tor estimating the fat-free mass of children (10-19 years) as well as American Indian, black, Hispanic, and white adults. Anthropometric prediction equations that use a combination of circumferences and bony diameters are recommended for older adults (up to 79 years of age), as well as obese men and women.

The purpose of this study was to evaluate the suitability of the Movement Assessment Battery for Children (M-ABC) for use in Greater China. Chinese children numbering 255 between the ages of 4 and 6 from Hong Kong and 544 from Taiwan were tested individually on the standardized test contained within the M-ABC. Data from these 799 children were compared to that presented in the test manual for the 493 children of the same age comprising the United States standardization sample. Both within-culture and cross-cultural differences were statistically significant when all items of the M-ABC were examined simultaneously, but effect sizes were too low to be considered meaningful. However, descriptive analysis of the cut-off scores used for impairment detection on the test suggested that adjustments to some items would be desirable for these particular Chinese populations.

A paucity of information exists concerning reliability of the KT-1000 knee arthrometer (MEDmetric Corp., San Diego, CA) when used by different clinicians to assess the same anterior cruciate ligament-deficient patient. The purpose of this study was to determine the reliability and standard error of measurement of four clinicians who routinely report KT-1000 arthrometer values to referring orthopedic surgeons. Two physical therapists and two athletic trainers performed anterior laxity tests using the KT-1000 on 19 subjects. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were used to determine reliability. Intratester ICC ranged from .98 to 1.0 and intratester SEM ranged from 0.0 to .28 mm. Intertester ICC and SEM for all four testers were .53 and 1.2 mm, respectively. A 95% confidence interval (M ± 1.96 × SEM) of the intertester variability ranged from −0.18 to 4.52 mm. Therefore, large intertester variation existed in KT-1000 values. Each facility should standardize testing procedures and establish intratester and intertester reliability for all clinicians reporting KT-1000 values.
