Gymnastics judges and former gymnasts have been shown to be quite accurate in detecting errors and accurately judging performance. PURPOSE: The purpose of the current study was to examine if this superior judging performance is reflected in judges' gaze behavior. METHOD: Thirty-five judges were asked to judge 21 gymnasts who performed a skill on the vault in a video-based test. Classifying 1 sample on 2 different criteria, judging performance and gaze behavior were compared between judges with a higher license level and judges with a lower license level and between judges who were able to perform the skill (specific motor experience [SME]) and those who were not...

PURPOSE: The net height in tennis (0.91 m) is approximately 50% of a professional tennis player's height. Children are also expected to play with this net height, even though it is approximately 70% of the average 10-year-old's height. This study examined the immediate effect of lowering net height on the performance characteristics of skilled junior tennis players aged 10 years and younger. METHOD: Sixteen players were matched in 8 pairs of even tennis ability and same sex...

Physical education is critical to addressing childhood obesity, yet many school-based programs do not meet established quality standards and teachers are called upon to change. Little is known about how change is initiated and its associated internal and external factors. PURPOSE: The purpose of this study was to investigate physical education teacher change that was self-initiated and externally initiated and to examine dispositions toward the change process relative to initiation. METHOD: A random national sample of physical educators representing each SHAPE America - Society of Health and Physical Educators regional district participated in a survey measuring past programming changes, primary initiators of change, and teachers' dispositions toward change...

PURPOSE: Several studies have demonstrated that physiological variables predict cycling endurance performance. However, it is still unclear whether the predictors will change over different performance durations. The aim of this study was to assess the correlations between physiological variables and cycling time trials with different durations. METHODS: Twenty trained male cyclists (maximal oxygen uptake [VO2max] = 60.5 ± 5.6 mL/kg/min) performed 4 separate experimental trials during a 2-week period...

PURPOSE: This study aimed to compare the energy expenditure and intensity of active video games to that of treadmill walking in children and adolescents. METHOD: Seventy-two boys and girls (aged 8-13 years) were recruited from local public schools. Energy expenditure and heart rate were measured during rest, during 3-km/hr, 4-km/hr, and 5-km/hr walks, and during active games (Adventure, Boxing I, Boxing II, and Dance). During walking and active games, we also assessed physical activity using an accelerometer...

PURPOSE: This study explored the effect of whole-body vibration (WBV) using accelerations of 2.56 g to 7.68 g on lower-body detraining. METHODS: All participants (N = 20) were trained using a lower-body resistance-training program for 30 min twice per week from Week 0 to Week 6. At the end of the program, they were randomly assigned to a control group that performed no further training or a WBV group that performed a progressive static WBV program. Data for the 5-repetition-maximum (5RM) squat and extensors and flexors of the knee and ankle were collected at Weeks 0, 6, 8, 10, and 12 for all participants...

PURPOSE: Variability in the timing of infant developmental milestones is poorly understood. We used a twin analysis to estimate genetic and environmental influences on motor development and activity levels in infancy. METHOD: Data were from the Gemini Study, a twin birth cohort of 2,402 families with twins born in the United Kingdom in 2007. Parents reported motor activity level for each of the twins at age 3 months using the Revised Infant Behavior Rating Scale and reported the ages at which they first sat unsupported, crawled, and walked unaided...

PURPOSE: Children from disadvantaged settings are at risk for delays in their object-control (OC) skills. Fundamental motor skill interventions, such as the Successful Kinesthetic Instruction for Preschoolers (SKIP) Program, are highly successful when led by motor development experts. However, few preschools employ such experts. This study examined the extent to which Head Start teachers delivering an 8-week teacher-led SKIP (T-SKIP) intervention elicited learning of OC skills for Head Start children...
