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.

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.

Tests constructed using item response theory (IRT) produce invariant item and test parameters, making it possible to construct tests and test items useful over many populations. This paper heuristically and empirically compares the utility of classical test theory (CTT) and IRT using psychomotor skill data. Data from the Test of Gross Motor Development (TGMD) (Ulrich, 1985) were used to assess the feasibility of fitting existing IRT models to dichotomously scored psychomotor skill data. As expected, CTT and IRT analyses yielded parallel interpretations of item and subtest difficulty and discrimination. However, IRT provided significant additional analysis of the error associated with estimating examinee ability. The IRT two-parameter logistic model provided a superior model fit to the one-parameter logistic model. Although both TGMD subtests estimated ability for examinees of low to average ability, the object control subtest estimated examinee ability more precisely at higher difficulty levels than the locomotor subtest. The results suggest that IRT is particularly well suited to construct tests that can meet the challenging measurement demands of adapted physical education.

To determine the relationship between distance covered and player load (PL: sum of accelerations in all 3 planes of movement) in hockey training and competition.


Elite male hockey players (N = 24) wore player-tracking devices in 7 international matches and 7 training sessions. Players were arranged in 4 positional groups (strikers, attacking midfielders, defensive midfielders, defenders) in competition but had generic roles in training. Relationships between distance and PL were assessed in both absolute (m, AU) and relative (m/min, AU/min) terms and were compared between matches and training and between positions within matches, using the Fisher Z test.


In competition, the absolute distance–PL relationship was very large overall (r = .868), with no differences between positions. The relative distance–PL relationship was moderate overall (r = .486) and weaker in strikers than in defensive midfielders (Z = 1.785, P = .037) and defenders (Z = 1.690, P = .045). In training, the absolute distance–PL relationship was very large (r = .742), and large (r = .633) in relative terms. The relationship was stronger in competition than training for absolute values (Z = 2.824, P = .005) but not different for relative values.


The strong relationship between these variables suggests that PL in hockey is mostly accumulated through running and other locomotor actions, such that PL is not effective in quantifying other activities (evasion, low stance) that contribute to physiological demands, particularly in training.

Infants show a dramatic shift in postural and emotional responsiveness to peripheral lamellar optic flow (PLOF) following crawling onset. The present study used a novel virtual moving room to assess postural compensation of the shoulders backward and upward and heart rate acceleration to PLOF specifying a sudden horizontal forward translation and a sudden descent down a steep slope in an infinitely long virtual tunnel. No motion control conditions were also included. Participants were 53 8.5-month-old infants: 25 prelocomotors and 28 hands-and-knees crawlers. The primary findings were that crawling infants showed directionally appropriate postural compensation in the two tunnel motion conditions, whereas prelocomotor infants were minimally responsive in both conditions. Similarly, prelocomotor infants showed nonsignificant changes in heart rate acceleration in the tunnel motion conditions, whereas crawling infants showed significantly higher heart rate acceleration in the descent condition than in the descent control condition, and in the descent condition than in the horizontal translation condition. These findings highlight the important role played by locomotor experience in the development of the visual control of posture and in emotional reactions to a sudden optically specified drop. The virtual moving room is a promising paradigm for exploring the development of perception–action coupling.

The Test of Gross Motor Development (TGMD) was used to assess the fundamental motor skills of 91 girls and 110 boys aged 4 to 18 years who attended two schools for students who are deaf. Average hearing loss, determined by better ear average, was 96.94 dB (SD = 14.40 dB). Modifications to the procedures for administering the TGMD included visual demonstrations and the use of signing to communicate instructions. The raw score means of subjects aged 4–10 years who were deaf were lower than those of the TGMD standardization sample of same-aged children who could hear at six of seven age levels on both the object-control and locomotor subscales. However, there were relatively small differences in the mean scores of the two groups. Subjects with mature movement patterns for the throw, kick, jump, and run performed better on quantitative tests for those skills than subjects with immature patterns. Typical age and gender patterns of skill acquisition were revealed for both the qualitative and quantitative aspects of the fundamental motor skills examined.
