Purpose:

To investigate the speed profiles of individual training modes in comparison with wheelchair rugby (WCR) competition across player classifications.

Methods:

Speed profiles of 15 international WCR players were determined using a radio-frequency-based indoor tracking system. Mean and peak speed (m/s), work:rest ratios, and the relative time spent in (%) and number of high-speed activities performed were measured across training sessions (n = 464) and international competition (n = 34). Training was classified into 1 of 4 modes: conditioning (n = 71), skill-based (n = 133), game-related (n = 151), and game-simulation drills (n = 109). Game-simulation drills were further categorized by the structured duration, which were 3-min game clock (n = 44), 8-min game clock (n = 39), and 10-min running clock (n = 26). Players were grouped by their International Wheelchair Rugby Federation classification as either low-point (≤1.5; n = 8) or high-point players (≥2.0; n = 7).

Results:

Conditioning drills were shown to exceed the demands of competition, irrespective of classification (P ≤ .005; effect size [ES] = 0.6–2.0). Skill-based and game-related drills underrepresented the speed profiles of competition (P ≤ .005; ES = 0.5–1.1). Mean speed and work:rest ratios were significantly lower during 3- and 8-min game-simulation drills in relation to competition (P ≤ .039; ES = 0.5–0.7). However, no significant differences were identified between the 10-min running clock and competition.

Conclusions:

Although game-simulation drills provided the closest representation of competition, the structured duration appeared important since the 10-min running clock increased training specificity. Coaches can therefore modify the desired training response by making subtle changes to the format of game-simulation drills.

Intact classes of mentally retarded and nonhandicapped children were administered the Physical Dexterity scales of the System of Multicultural Pluralistic Assessment and the short form of the Bruininks-Oseretsky Test of Motor Proficiency. Separate discriminant analyses of each data set revealed that the subjects comprised four distinct levels of motor performance. Although overall predicted correct classification was above 65%, misclassifications occurred in each class. Differences resulting from the separate analyses suggest differential program placement for physical education. There is a tendency for the Physical Dexterity data to predict higher levels of motor functioning than the Motor Proficiency data for half of the mentally retarded children.

An analysis of the 434 free communications by the 575 presenters at the first seven annual meetings of NASSS (1980–1986) reveals several important patterns and trends with respect to (a) number of free communications, (b) number of presenters, (c) presenter’s sex, (d) presenter’s institutional affiliation, and (e) dual and multiple authorships. A classification of the free communications by subject matter reveals which research topics are of current interest to sport sociologists. Implications of these data for understanding the current stage of development of the subfield are discussed in relation to Mullins’ four-stage developmental model for scientific specialties.

Background:

Little is known about the relationships between objectively measured commute distance with actual and perceived transport-related physical activity (TPA) engagement.

Methods:

A telephone survey assessed travel behaviors to place of work/study within an adult sample (n = 772) residing in New Zealand.

Results:

Overall, 50% of respondents perceived they could, and 10% of the sample actually did, use TPA modes to commute to their occupation for distances less than 5 km. Differences between TPA perceptions and engagement existed for all distance classifications, and prevalence declined as distances increased.

Conclusions:

Differences between TPA engagement and perceptions were evident. Actual and perceived TPA engagement levels declined as commute distance increased.

This study examines, in a comparative context, the attitudes of undergraduate students toward the integration of people with disabilities in activity settings. The Physical Educators’ Attitudes Toward Teaching the Handicapped instrument was used to test preservice physical education undergraduates (N = 371) from universities in England, Denmark, Belgium, and Portugal on attitude variables previously found significant in North American research. Mann-Whitney U analysis revealed significant attitudinal differences between the variables of gender, previous experience with disability, and disability classification (physical or learning disability); between cross-cultural influences of the Belgian sample and the English, Danish, and Portuguese samples; and between the English and the Danish samples.

This article proposes a theory- and practice-based model for adapting physical activities. The ecological frame of reference includes Dynamic and Action System Theory, World Health Organization International Classification of Function and Disability, and Adaptation Theory. A systematic model is presented addressing (a) the task objective, (b) task criteria, (c) limitation and enablement criteria, (d) performance errors, and (e) adaptation suggestions. Four individual case examples are described, referring to the conceptual model and depicting its use in various settings of physical activity, including physical education, rehabilitation, competition, and recreation.

Background:

Curriculum interventions aimed at increasing physical activity in schools may prove useful in contexts where changes in policy/environment are not feasible. Design/evaluation of interventions targeting minority groups is important in light of well-publicized health disparities. Religious minorities represent a special subset that may positively respond to interventions tailored to their unique beliefs, which to date have been relatively underreported.

Methods:

Muslim American youth (n = 45) attending a parochial middle school participated in a religiously- and culturally-tailored 8-wk, interdisciplinary pedometer intervention. School-time ambulatory activity was quantified using a delayed multiple-baseline across subjects ABA design. Visual analysis of graphic data as well as repeated-measures ANOVA and ANCOVA and post hoc contrasts were used to analyze step counts including the moderating effects of day type (PE, no-PE), gender, BMI classification, grade, and time.

Results:

The intervention elicited modest increases in males’ steps only with effect decay beginning midintervention. BMI classification and grade were not associated with changes in steps.

Conclusions:

Full curricular integration by affected classroom teachers, staff modeling of PA behavior, and alternative curriculum for girls’ PE classes may further potentiate the intervention.

Background:

The Kenz Lifecorder EX (KL) is a relatively new, moderately priced, user friendly accelerometer that tracks step counts and time spent in various intensity classifications. Thus, the KL is an attractive instrument for researchers and the public. However, there is limited research comparing the KL’s output to other accelerometers during free-living conditions. Therefore the purpose of this study was to compare KL versus ActiGraph (AG) outputs of step counts and time spent in various intensity classifications during free-living conditions.

Methods:

Ten men and 10 women volunteers wore an AG (right side) and 2 KL (right side: KL-R vs. left side: KL-L) accelerometers on their waistline during waking hours for one day.

Results:

KL-R vs. KL-L yielded similar physical activity (PA) output. The AG recorded fewer steps compared with KL-L (P = .002) but was similar to the KL-R. The KL-R and KL-L yielded lower estimates of accumulated time spent in moderate PA compared with most AG intensity derivations (P < .003). There were no differences between KL-R and KL-L vs. the AG for time spent in vigorous PA.

Conclusions:

The KL provides similar estimates of step counts and time spent in vigorous PA compared with established AG intensity derivations.

Background:

The purpose of the study was to evaluate race-specific FITNESSGRAM® body mass index (BMI) standards in comparison to the recommended standards, i.e., percent fat (%BF) ≥25 in boys and %BF ≥32 in girls.

Methods:

BMI and %BF were estimated in 1,968 Black and White children ages 6-14 years, using methods similar to those used to develop the current FITNESSGRAM standards. Multiple regression was employed to develop age-, sex-, and race-specific BMI standards. Percent agreement and modified kappa (κq) were used to evaluate agreement with the %BF standards, and sensitivity and specificity were used to evaluate classification accuracy.

Results:

Race significantly (p < .05) and meaningfully (β = 2.3% fat) added to the relationship between BMI and %BF. Agreement of the race-specific BMI standards with %BF standards was moderate to high (κq = .73–.88), and classification accuracy improved on the current FITNESSGRAM BMI standards.

Conclusions:

Race-specific BMI standards appear to be a more accurate representation of unhealthy %BF levels than the current FITNESSGRAM BMI standards.

Background:

Optimal levels of moderate-to-vigorous physical activity (MVPA) have been shown to improve health and academic outcomes in youth. Limited research has examined MVPA trajectories throughout a daily middle school physical education (PE) curriculum. The purpose of this study was to examine MVPA trajectories over a daily PE curriculum and the modifying effects of sex, body composition, and cardiorespiratory endurance.

Methods:

One hundred 7th- and 8th-grade students participated in daily PE lessons. There were 66 lessons throughout the semester. MVPA was monitored during each lesson using NL-1000 piezoelectric pedometers. Students were classified into FITNESSGRAM Healthy Fitness Zones using estimated VO2 Max and Body Mass Index (BMI). A population averaged generalized estimating equation was employed to examine MVPA trajectories.

Results:

On average, students’ MVPA decreased over time (β = –0.35, P < .001). Poor student VO2max classification significantly modified the trajectories (β = –0.14, P < .001), however poor BMI classification did not have a modifying effect (β = 0.03, P = .158).

Conclusions:

MVPA decreased in daily PE over time and cardiorespiratory endurance significantly modified the trajectories. The results support that extra efforts have to be made by teachers and students to sustain MVPA behaviors over a semester.
