ABSTRACT

Background: Cycling has gained more attention as an important lifelong physical activity. Learning to cycle independently without assistance is a milestone for most children that requires time and practice to master. Cycling was recently added to the motor development model and so a valid and reliable measure of cycling ability is required to allow accurate assessment of the skill. Cycling has many health benefits along with being a commonly reported physical activity globally and therefore is an important skill to promote in early childhood and throughout life. To date, there are no measurement tools examining the developmental process to independent cycling in the early childhood years. The current study aimed to develop and assess the inter-rater and test-retest reliability of the ‘KIM Cycling Scale’.

Methods: Development of the scale occurred in four phases: (1) development of criteria and stages, which used observation of children when learning to cycle and expert panels to develop the initial developmental stages, (2) review of instructions and criteria and pilot inter-rater and test-retest reliability, to ensure that the scale could be used as a standalone scale without requiring further instructions (3) cycling intervention, which allowed assessment of the developmental nature of children along the scale as they learn to cycle independently and to assess typical and alternate routes to independent cycling and (4) inter-rater and test-retest reliability.

Results: Ninety children took part in phase 1, thirty-six children took part in phase 2, seventy-four children took part in phase 3 and one hundred and forty-nine children took part in phase 4. All three hundred and forty-nine children were between 2 and 6 years. The developed scale included eight stages in total. The scale was found to have excellent inter-rater reliability (ICC?=?0.97, 95% CI?=?0.96–0.98) and good to excellent test-retest reliability [(ICC?=?0.91, 95% CI?=?0.87–0.94) & (ICC?=?0.90, 95% CI?=?0.85–0.93)]. Typical routes to independent cycling along the scale were examined and reported as being step-wise on all occasions except one where a two stage jump was as common as the step-wise route. Alternate routes were also reported.

Conclusion: The current study developed a reliable measurement tool for assessing children between 2 and 6 years of age on the developmental process to independent cycling. Having a cycling scale will allow teachers and practitioners to assess competence in cycling and moreover, track changes in skill development. Furthermore, parents could also use the scale to better understand and better asses their child’s progression when learning to cycle.  相似文献

Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m2) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.  相似文献

Background:Osteoarthritis is one of the leading causes of pain and disability worldwide,and a large percentage of patients with osteoarthritis are individuals who are also obese.In recent years,a series of animal models have demonstrated that obesity-inducing diets can result in synovial joint damage(both with and without the superimposition of trauma),which may be related to changes in percentage of body fat and a series of low-level systemic inflammatory mediators.Of note,there is a disparity between whether the dietary challenges commence at weaning,representing a weanling onset,or at skeletal maturity,representing an adult onset of obesity.We wished to evaluate the effect ofthe dietary exposure time and the age at which animals are exposed to a high-fat and high-sucrose(HFS) diet to determine whether these factors may result in disparate outcomes,as there is evidence suggesting that these factors result in differential metabolic disturbances.Based on dietary exposure time,we hypothesized that rats fed an HFS diet for 14 weeks from weaning(HFS Weanling) would demonstrate an increase in knee joint damage scores,whereas rats exposed to the HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult) and rats exposed to a standard chow diet(Chow)would not display an increase in knee joint damage scores.Methods:Male Sprague-Dawley rats were fed either an HFS diet for 14 weeks from weaning(HFS Weanling) or an HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult).At sacrifice,joints were scored using the modified Mankin Criteria,and serum was analyzed for a defined subset of inflammatory markers(Interleukin-6,leptin,monocyte chemoattractant protein-1,and tumor necrosis factorα).Results:When the HFS Weanling and HFS Adult groups were compared,both groups had a similar percent of body fat,although the HFS Weanling group had a significantly greater body mass than the HFS Adult group.The HFS Weanling and HFS Adult animals had a significant increase in body mass and percentage of body fat when compared to the Chow group.Although knee joint damage scores were low in all 3 groups,we found,contrary to our hypothesis,that the HFS Adult group had statistically significant greater knee joint damage scores than the Chow and HFS Weanling groups.Furthermore,we observed that the HFS Weanling group did not have significant differences in knee joint damage scores relative to the Chow group.Conclusion:These findings indicate that the HFS Weanling animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group.Interestingly,when assessing various serum proinflammatory markers,no significant differences were detected between the HTS Adult and HFS Weanling groups.Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated,these findings indicate that dietary exposure time maybe less important than the age at which an HFS diet is introduced.Moreover,increases in serum proinflammatory mediators do not appear to be directly linked to knee joint damage scores in the HFS Weanling group animals but may be partially responsible for the observed knee joint damage in the adults over the very short time of exposure to the HFS diet.  相似文献

Early childhood and elementary education emerged from a variety of knowledge and research bases. Tensions emerged as they were brought together in a unified public kindergarten through 12th-grade educational system. This review describes how standards and accountability policies have exacerbated tensions between early childhood and elementary curriculum and instructional approaches and impacted the voice and role of early childhood educators. We argue that this is a critical time for understanding and addressing these issues.  相似文献

Adverse childhood experiences (ACEs) are important public health concerns, with links to higher prevalence rates of both health-risk behaviors and physical health difficulties in adulthood. Research has demonstrated an association between early adversity and long-term health-risk behavior development. The current study assessed the role of emotion dysregulation and facets of impulsivity as potential mediators in the relation between ACEs and general health-risk behaviors, including alcohol-related consequences and risky sexual behavior. College students (N = 668) completed online questionnaires that assessed history of ACEs, emotion regulation difficulties, impulsivity under extreme affect, and current engagement in health-risk behaviors. Emotion dysregulation and impulsivity under extreme positive emotion, but not negative emotion, demonstrated a significant serial mediation between ACEs and alcohol-related consequences. Results also suggest that emotion dysregulation mediates the relation between early adversity and all three outcomes (i.e., overall engagement in maladaptive behavior, alcohol-related consequences, and risky sexual behavior). Impulsivity under positive or negative affect did not demonstrate a mediation effect on the three outcomes. Results of this study highlight the importance of assessing for emotion regulation skills when working with young adults with histories of adversity.  相似文献

The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative.  相似文献

This paper highlights the similarities and differences of seven nature kindergarten programmes in Australia and New Zealand. The study targeted three programmes from New Zealand and four from Australia. Participant observations and semi-structured interviews were used to build a profile of each site. The profiles were compared on factors such as philosophical influences, curriculum design, site location, safety requirements and programme activity. In many ways, the programmes were quite similar, and this was attributed to synergies between the respective curriculum frameworks and the influence of the European Forest School movement. There were, however, some unique features at each site and differences attributed to national perspectives. It is anticipated that the profiling of philosophical and logistical dimensions of nature programmes implemented in exemplar settings can help to inspire other early childhood educators and encourage them to reposition nature pedagogy as part of their own early childhood programmes.  相似文献

Violence is a burdensome problem in daily psychiatric practice, even though the diagnosisof a mental disorder is not sufficient to determine a violent behavior; therefore, other factors are involved. We predicted that the participants could be distributed in two groups (e.g. high versus low violence-maltreatment groups) because this grouping would better describe specific patterns of associations in a clinical sample. We aimed to investigate the relation between interpersonal violence and maltreating experiences in childhood. Affective states and personal functioning were also explored as meaningful outcomes. Consecutive patients (N = 101) admitted to a psychiatric unit were evaluated with the Risky Families Questionnaire, the Psychological Maltreatment Review, the Karolinska Interpersonal Violence Scale (KIVS), the Positive and Negative Affect Schedule and the Personal and Social Performance Scale. Single, with average education and unemployed individuals showed significantly higher KIVS scores. High levels of interpersonal violence (IV) in childhood correlated with a harsh family climate in early life. Moreover, IV correlated with perceived parental maltreatment and did not with parental support. The cluster analysis identified two clusters of patients. The first (n = 41) showed negative dysfunctional experiences; the second (n = 60) showed a more positive perception of parental support.The impairment of social functioning and emotions regulation are both involved in this complex relation. The study supports the hypothesis of a clustering of patients that needs tailored management of violence causes and consequences.  相似文献

The quality of educational processes with children of preschool age and long-term educational outcomes are largely related to the work quality of teachers. Lifelong learning and professional development, as predictors of quality, need to be regarded as an ongoing task for kindergarten teachers. Findings of an empirical study of Croatian kindergarten teachers’ views (N = 388) on professional development point to a link between teachers’ intrinsic motivation and their professional development. Motivation explains 46.87% of the variance Personal commitment to professional development. A slight positive correlation was found between the level of formal education and the frequency of professional development (r = .216, p < .01). Although the level of education of kindergarten teachers is not a good independent predictor, it affects readiness to self-fund professional development (p < .01). As for the significance of conferences as a form of professional development, participants of the study identified them as an effective opportunity (M = 4.68, SD = .52), promoting both quality practices (M = 4.69, SD = .54) and exchange of experiences (M = 4.68, SD = .56). The length of participants’ professional work experience affects their assessment of the significance of practitioners’ networking as a way of improving the quality of everyday practices (F = 1.43, p < .05).  相似文献
