A comparison of anthropometric and training characteristics of Ironman triathletes and Triple Iron ultra-triathletes     

Knechtle B  Knechtle P  Rüst CA  Rosemann T 《Journal of sports sciences》2011,29(13):1373-1380

We examined differences in anthropometry and training between 64 Triple Iron ultra-triathletes competing over 11.4 km swimming, 540 km cycling, and 126.6 km running, and 71 Ironman triathletes competing over 3.8 km swimming, 180 km cycling, and 42.2 km running. The association of anthropometry and training with race time was investigated using multiple linear regression analysis. The Triple Iron ultra-triathletes were smaller (P < 0.05), had shorter limbs (P < 0.05), a higher body mass index (P < 0.05), and larger limb circumferences (P < 0.01) than the Ironman triathletes. The Triple Iron ultra-triathletes trained for more hours (P < 0.01) and covered more kilometres (P < 0.01), but speed in running during training was slower compared with the Ironman triathletes (P < 0.01). For Triple Iron ultra-triathletes, percent body fat (P = 0.022), training volume per week (P < 0.0001), and weekly kilometres in both cycling (P < 0.0001) and running (P < 0.0001) were related to race time. For Ironman triathletes, percent body fat (P < 0.0001), circumference of upper arm (P = 0.006), and speed in cycling training (P = 0.012) were associated with total race time. We conclude that both Triple Iron ultra-triathletes and Ironman triathletes appeared to profit from low body fat. Triple Iron ultra-triathletes relied more on training volume in cycling and running, whereas speed in cycling training was related to race time in Ironman triathletes.  相似文献   

Assessing Quality in Toddler Classrooms Using the CLASS-Toddler and the ITERS-R     

Karen M. La Paro  Amy C. Williamson  Bridget Hatfield 《Early education and development》2014,25(6):875-893

Many very young children attend early care and education programs, but current information about the quality of center-based care for toddlers is scarce. Using 2 observation instruments, the Infant/Toddler Environment Rating Scale–Revised (ITERS-R) and the Classroom Assessment Scoring System, Toddler Version (CLASS-Toddler), 93 child care classrooms for toddlers across the state of North Carolina, representing a range of quality, were assessed to determine overall quality, and associations between observed quality and teachers' ratings of child behavior problems and competence outcomes using the Brief Infant Toddler Social Emotional Assessment. Research Findings: Findings indicated that overall, toddler classrooms were rated as being of moderate quality. Associations between observed quality and teacher-reported child behavior problems and competence outcomes indicated that CLASS-Toddler ratings were positively associated with fewer behavior problems; specifically, children in classrooms with higher levels on the CLASS-Toddler domains of Emotional and Behavioral Support as well as Engaged Support for Learning were reported to have fewer behavior problems. Similarly, the ITERS-R subscales of Interaction and Listening and Talking were positively related to fewer reported behavior problems. Regression models showed that the CLASS-Toddler Emotional and Behavioral Support domain predicted differences in child behavior problems. Practice or Policy: Findings suggest the need for additional research related to very young children's experiences in center-based child care to examine associations between quality and child experiences and outcomes. Children's experiences over time need to be examined to understand how these early child care experiences are related to children's later school adjustment and performance. On a related note, professional development for teachers in toddler classrooms needs to be addressed in terms of preparing effective teachers for young children during the toddler developmental period.  相似文献

Incidence and risk for traumatic and overuse injuries in top-level road cyclists     

De Bernardo N  Barrios C  Vera P  Laíz C  Hadala M 《Journal of sports sciences》2012,30(10):1047-1053

All traumatic and overuse injuries occurring during an average period of 4 years (2002/09) in a group of 51 currently active road top-level cyclists were retrospectively registered through clinical interviews. Average age was 25.8 years. Average training and competition period was 28.3 ± 2.4 h a week. Only 8 cyclists (15.6%) were completely free from lesions during the period of study. The remaining 43 cyclists suffered a total of 112 lesions; however, 9 out of these were unrelated to their cycling practice. These 103 cycling-related injuries include 50 (48.5%) traumatic and 53 (51.5%) overuse injuries. Twenty-eight fractures were reported, the clavicle being the most frequently affected bone (11 cases). The 68.5% of overuse injuries were located in the lower limbs. Most overuse injuries (89.6%) occurred during the training period. According to the injury abbreviated scale (AIS), severe lesions were only found in 4 cases (8% of traumatic injuries). Overall injury rates were 0.50 per racer/year, 2.02 per studied racer, and 0.007 per 1000 km of training and competition. Active professional top-level cyclists are exposed to a high injury risk. According to the scarce previously published data the current study provides relevant information on the injury occurrence of still active top-level road cycling.  相似文献   

A faster running speed is associated with a greater body weight loss in 100-km ultra-marathoners     

Knechtle B  Knechtle P  Wirth A  Alexander Rüst C  Rosemann T 《Journal of sports sciences》2012,30(11):1131-1140

In 219 recreational male runners, we investigated changes in body mass, total body water, haematocrit, plasma sodium concentration ([Na(+)]), and urine specific gravity as well as fluid intake during a 100-km ultra-marathon. The athletes lost 1.9 kg (s = 1.4) of body mass, equal to 2.5% (s = 1.8) of body mass (P < 0.001), 0.7 kg (s = 1.0) of predicted skeletal muscle mass (P < 0.001), 0.2 kg (s = 1.3) of predicted fat mass (P < 0.05), and 0.9 L (s = 1.6) of predicted total body water (P < 0.001). Haematocrit decreased (P < 0.001), urine specific gravity (P < 0.001), plasma volume (P < 0.05), and plasma [Na(+)] (P < 0.05) all increased. Change in body mass was related to running speed (r = -0.16, P < 0.05), change in plasma volume was associated with change in plasma [Na(+)] (r = -0.28, P < 0.0001), and change in body mass was related to both change in plasma [Na(+)] (r = -0.36) and change in plasma volume (r = 0.31) (P < 0.0001). The athletes consumed 0.65 L (s = 0.27) fluid per hour. Fluid intake was related to both running speed (r = 0.42, P < 0.0001) and change in body mass (r = 0.23, P = 0.0006), but not post-race plasma [Na(+)] or change in plasma [Na(+)] (P > 0.05). In conclusion, faster runners lost more body mass, runners lost more body mass when they drank less fluid, and faster runners drank more fluid than slower runners.  相似文献   

Examining Differences in Students’ Beliefs and Attitudes: An Important Element of Performance-Based Assessment Systems for Teacher Preparation Programs     

Catherine Scott-Little  Karen M. La Paro  Amanda Weisner 《Journal of Early Childhood Teacher Education》2013,34(4):379-390

The National Council for Accreditation of Teacher Education (NCATE) program review process increasingly emphasizes the importance of performance-based assessment of early childhood teacher preparation programs. As part of the effort to address performance-based assessment requirements, the teacher educator program described in this study examined students’ beliefs related to developmentally appropriate practice, attitudes toward children, and perceived competencies at different points in the program and upon graduation. One hundred eighteen students and 78 recent graduates participated. Results suggest that students’ beliefs are more consistent with developmentally appropriate practices and with a progressive or child-centered approach at later points in the program. In general, participants felt they were more competent in what they know about early childhood practices than in how they implement the practices. Students nearing completion of the program and those who had graduated reported that they knew more about early childhood practices than students enrolled in early courses in the program, and graduates felt they were more competent to implement early childhood practices than students not enrolled in the program. Results are discussed in terms of implications for examining teacher preparation programs.  相似文献   

Quality in Kindergarten Classrooms: Observational Evidence for the Need to Increase Children's Learning Opportunities in Early Education Classrooms     

Karen M. La Paro  Bridget K. Hamre  Jennifer Locasale-Crouch  Robert C. Pianta  Donna Bryant  Dianne Early 《Early education and development》2013,24(4):657-692

Research Findings: Using observational data gathered in 730 kindergarten classrooms in 6 states, the present study focuses on the quality of children's learning opportunities in kindergarten classrooms. Findings show that overall, children experience moderate to low levels of quality in the areas of classroom organization and instructional support in kindergarten. Results are also presented in comparison to children's experiences in the pre-kindergarten year. These comparisons indicate that kindergarten children spend a greater proportion of the school day in language arts, math, and whole-group instruction and less time in centers than they do in pre-kindergarten. An examination of predictors of kindergarten classroom quality indicated that program characteristics (i.e., adult–child ratio, length of school day) and teacher psychological variables (i.e., beliefs and depressive symptoms) were stronger predictors of classroom quality than were teacher experience and educational background. Practice or Policy: Findings are discussed in terms of implications for children's academic and social development in kindergarten as well as for kindergarten teacher preparation and development.  相似文献   

Technology in education: Equity and theory are key   总被引：1，自引：0，他引：1  

La Vergne Rosow 《TechTrends》2001,45(4):31-39

For those with access to instructional technology, teaching and learning can be far more interesting and far-reaching than ever before. We as educators can empower our students with an understanding of how to employ these resources to meet their immediate and lifelong goals. We as members of the education industry must work to assure equal access to all students.  相似文献
