This study compared the effectiveness of data based and creative dance pedagogies in relation to motor skill performance and self-concept of mentally retarded students. Subjects (N=35) were moderately mentally retarded males and females, ages 11 to 16 years, in special education classes. Their mean age was 12.88 years in the data based group and 13.47 years in the creative dance group. Excluding testing, the study lasted 8 weeks. Each group received 40 lessons of 30 minutes each. Data based pedagogy was based on the work of Dunn, Morehouse, and Dalke (1979), and creative dance pedagogy was based primarily on the work of Riordan (Fitt & Riordan, 1980). Pretest and posttest data were collected through administration of the Data Based Dance Skills Placement Test, selected subtests of the Cratty Six-Category Gross Motor Test, and the Martinek-Zaichkowsky Self-Concept Scale. Multivariate analysis of covariance revealed no difference between pedagogies. The group means indicated improvement in dance skill performance but not in self-concept or body perception, balance, and gross and locomotor agility.

The development of motor skill proficiency during childhood is cumulative and influenced by physical growth and maturation, genetic potential, affordances in the physical and social environment, and the interactions between these factors. Therefore, typically during childhood, the trajectory of change in motor proficiency is positive. To lend developmental validity to the revision of the Test of Gross Motor Development—3rd edition (TGMD-3), this longitudinal study examined whether the skills and subtests of the TGMD-3 changed as might be expected from grade 3 to grade 4 among 277 children. The findings of this study lend support to the developmental validity of the TGMD-3 in that (1) there was within-individual change in the expected direction for both locomotor and ball skills, (2) consistent with the majority of research, boys had significantly higher ball skills scores than girls in both grade 3 and grade 4, and (3) the mean percent of maximum possible scores were in the range of approximately 60–75, which demonstrates that the majority of 8- and 9-year-old children had not reached a ceiling on this test.

The Test of Gross Motor Development, 2nd edition (TGMD-2), is one of the most widely used measures of motor skill competence. The purpose of this study was to examine if differences in scores exist between expert and novice coders on the TGMD-2 (Ulrich, 2000).


Three coders, one expert and two novices, reviewed and scored young children’s (N = 43; Boys = 57%; Mage = 4.88, SD = 0.28) TGMD-2 data. The kappa statistic was used to determine agreement between expert and novice coders on the locomotor and object control subscale of the TGMD-2. Independent samples t tests and percent differences were then used to examine scoring differences for each of the twelve skills.


Results support that expert and novice coders do not demonstrate significant agreement when scoring the TGMD-2 except for when scoring the kick (t 41 = –1.3, p = .2) and the gallop (t 41= –1.7, p = .09).


This work demonstrates that more stringent or consistent training regimens are needed before allowing novices to code TGMD-2 data.

Motor skill competence has been associated with physical activity level, fitness, and other relevant health-related characteristics. Recent research has focused on understanding these relationships in children and adolescents, but little is known about subsequent years. The aim of this study was to examine the relationship between fundamental motor skill (FMS) ability and body mass index (BMI) in young adults.


Participants, 40 men and 40 women (M age = 19.25 yr, SD = 2.48), were assessed for BMI and motor competence with 10 fundamental motor skills (FMSs) using the Test for Fundamental Motor Skills in Adults (TFMSA).


BMI was negatively associated with total motor ability (r = –.257; p = .02) and object control skills (r = –.251; p = .02); the relationship with locomotor skills was marginally insignificant (r = –.204; p = .07). In regard to individual skills, a significant negative association was found for running, jumping, striking, and kicking (ps < .05). Multiple regression analysis indicated that BMI and gender predicted 42% of the variance in total FMS score; gender was the only significant predictor.


Overall, these preliminary findings suggest that young adults with higher FMS ability are more likely to have lower BMI scores.

The benefits of recess can be reaped by all students regardless of socioeconomic status, race, or gender and at relatively little cost. The purpose of this study was to examine physical activity (PA) variables related to the recess PA patterns of third and fourth grade children and the social preferences and individuals influencing their PA (friends and parents). Data were collected on students (N = 115) utilizing the System of Observing Children’s Activity and Relationships during Play (SOCARP) instrument. In addition, each child was interviewed during the recess period in which SOCARP was completed. Results found that boys spent significantly more time being very active (t (95.64) = 3.252, d = .62, p < .008) than girls and preferred sport activities (t = (73.62) 5.64, d = 1.14, p < .0125) in large groups (t (69.34) = 4.036, d = .83, p < .0125). Meanwhile, girls preferred locomotor activities (t (113) = 3.19, d = .60, p < .0125), sedentary activities (t (113) = 2.829, d = .53, p < .0125) and smaller groups (t (112.63) = 4.259, d = .79, p < .0125). All 115 participants indicated that they wanted to spend time with their friends during recess.

Increases in movement variability have previously been observed to be a hallmark property of cooraination changes between coupled oscillators that occur as movement frequency is scaled. Prior research on the walk-run transition in human locomotion has also demonstrated increases in variability around the transition region, supporting predictions of nonequilibrium phase transitions (Diedrich & Warren, 1995). The current study examined the coordinative patterns of both intra- and inter-limb couplings around the walk-run transition using two different temporal manipulations of locomotor velocity as a control parameter in healthy young participants (N = 11). Coordination variability did not increase before the transition. The nature of the change in continuous relative phase variability between gait modes was coupling-specific, and varying the time spent at each velocity did not have an overall effect on gait transition dynamics. Lower extremity inter-limb coordination dynamics were more sensitive to changes in treadmill velocity than intra-limb coordination. The results demonstrate the complexity of segmental coordination change in human locomotion, and question the applicability of dynamical bimanual coordination models to human gait transitions.

This preliminary investigation examined the potential effects of low birth weight on motor performance in children. Seventeen pairs of children were matched by age and placed in one of five age groups (5-9 years). One of each pair weighed 2,200 grams or less at birth (low birth weight, LBW) and the other weighed more than 2,200 grams at birth (normal birth weight, NBW). Three types of data were collected: motor development data, reaction time data, and anthropometric data. Nine paired t tests were performed. To control for alpha level inflation, the Bonferroni technique was employed. The two groups did not differ significantly in present body weight. Tests of gross motor development found the NBW group to be more advanced in both locomotor skills and object control skills. With regard to triceps skinfold, again the NBW group was found to have greater values. No other between-group measurements of body composition were significant. In addition, girls were significantly higher than boys in percent body fat. These preliminary results suggest the LBW children lag behind their NBW peers in the development of the basic fundamental motor skills.

Individuals with multiple sclerosis (MS) often have poor balance control that is especially apparent during dynamic tasks such as gait initiation (GI). The purpose of this study was to investigate how balance symptoms due to MS alter spatiotemporal variables, coordination, and temporal margins within the stability boundary during gait initiation. Twelve women with MS (Expanded Disability Status Scale [EDSS] mean = 4.0, SD = 1.4) and 12 women without MS (control group) initiated gait at their preferred speed. MS participants attained a slower anterior velocity because of smaller anterior center of mass displacements and took longer to complete the initiation of gait than the control group. MS participants exhibited a smaller posterior shift in center of pressure during GI and stepped with a longer dual support time than the control group. However, these changes may be due to differences in initiation velocity. Relative timing analysis showed invariance in postural and locomotor phases of gait initiation between groups. The MS group showed different coordination between anterior-posterior and medio-lateral center of pressure components while increasing temporal margins to the posterior and lateral stability boundaries in comparison with the control group. Overall, during gait initiation at their preferred speed the MS participants adopted a functional strategy that produces lower speed and reduced proximity to the stability boundaries prior to stepping.

Little is known about the effects of acute exercise on the cognitive functioning of children with cerebral palsy (CP). Selected cognitive functions were thus measured using a pediatric version of the Stroop test before and after maximal, locomotor based aerobic exercise in 16 independently ambulatory children (8 children with CP), 6–15 years old. Intense exercise had: 1) a significant, large, positive effect on reaction time (RT) for the CP group (preexercise: 892 ± 56.5 ms vs. postexercise: 798 ± 45.6 ms, p < .002, d = 1.87) with a trend for a similar but smaller response for the typically developing (TD) group (preexercise: 855 ± 56.5 ms vs. postexercise: 822 ± 45.6 ms, p < .08, d = 0.59), and 2) a significant, medium, negative effect on the interference effect for the CP group (preexercise: 4.5 ± 2.5%RT vs. postexercise: 13 ± 2.9%RT, p < .04, d = 0.77) with no significant effect for the TD group (preexercise: 7.2 ± 2.5%RT vs. postexercise: 6.9 ± 2.9%RT, p > .4, d = 0.03). Response accuracy was high in both groups pre- and postexercise (>96%). In conclusion, intense exercise impacts cognitive functioning in children with CP, both by increasing processing speed and decreasing executive function.

Athlete-tracking devices that include global positioning system (GPS) and microelectrical mechanical system (MEMS) components are now commonplace in sport research and practice. These devices provide large amounts of data that are used to inform decision making on athlete training and performance. However, the data obtained from these devices are often provided without clear explanation of how these metrics are obtained. At present, there is no clear consensus regarding how these data should be handled and reported in a sport context. Therefore, the aim of this review was to examine the factors that affect the data produced by these athlete-tracking devices and to provide guidelines for collecting, processing, and reporting of data. Many factors including device sampling rate, positioning and fitting of devices, satellite signal, and data-filtering methods can affect the measures obtained from GPS and MEMS devices. Therefore researchers are encouraged to report device brand/model, sampling frequency, number of satellites, horizontal dilution of precision, and software/firmware versions in any published research. In addition, details of inclusion/exclusion criteria for data obtained from these devices are also recommended. Considerations for the application of speed zones to evaluate the magnitude and distribution of different locomotor activities recorded by GPS are also presented, alongside recommendations for both industry practice and future research directions. Through a standard approach to data collection and procedure reporting, researchers and practitioners will be able to make more confident comparisons from their data, which will improve the understanding and impact these devices can have on athlete performance.
