Physical characteristics of experienced and junior open-wheel car drivers

Abstract

Despite the popularity of open-wheel car racing, scientific literature about the physical characteristics of competitive race car drivers is scarce. The purpose of this study was to compare selected fitness parameters of experienced and junior open-wheel race car drivers. The experienced drivers consisted of five Formula One, two GP2 and two Formula 3 drivers, and the nine junior drivers drove in the Formula Master, Koenig, BMW and Renault series. The following fitness parameters were tested: multiple reactions, multiple anticipation, postural stability, isometric upper body strength, isometric leg extension strength, isometric grip strength, cyclic foot speed and jump height. The group differences were calculated using the Mann-Whitney U-test. Because of the multiple testing strategy used, the statistical significance was Bonferroni corrected and set at P < 0.004. Significant differences between the experienced and junior drivers were found only for the jump height parameter (P = 0.002). The experienced drivers tended to perform better in leg strength (P = 0.009), cyclic foot speed (P = 0.024) and grip strength (P = 0.058). None of the other variables differed between the groups. The results suggested that the experienced drivers were significantly more powerful than the junior drivers: they tended to be quicker and stronger (18% to 25%) but without statistical significance. The experienced drivers demonstrated excellent strength and power compared with other high-performance athletes.     

Intra-abdominal pressures during activity in women using an intra-vaginal pressure transducer

Abstract

Strenuous physical activity has been linked to pelvic floor disorders in women. Using a novel wireless intra-vaginal pressure transducer, intra-abdominal pressure was measured during diverse activities in a laboratory. Fifty-seven women performed a prescribed protocol using the intra-vaginal pressure transducer. We calculated maximal, area under the curve and first moment of the area intra-abdominal pressure for each activity. Planned comparisons of pressure were made between levels of walking and cycling and between activities with reported high pressure in the literature. Findings indicate variability in intra-abdominal pressure amongst individuals doing the same activity, especially in activities that required regulation of effort. There were statistically significant differences in maximal pressure between levels of walking, cycling and high pressure activities. Results for area under the curve and first moment of the area were not always consistent with maximal pressure. Coughing had the highest maximal pressure, but had lower area under the curve and first moment of the area compared to most activities. Our data reflect novel findings of maximal, area under the curve and first moment of the area measures of intra-abdominal pressure, which may have clinical relevance for how physical activity relates to pelvic floor dysfunction.     

Internal and external influences on vocabulary development in preschool children

Competency in society's lingua franca plays a major role in the emergence of social disparities within education. Therefore, the present longitudinal study investigates vocabulary development and its predictors in preschool years. We focus on whether internal (phonological working memory) and external variables (preschool and home learning environment) have different impacts depending on parental native language. The study considers 547 children from 97 German preschools. Children's vocabulary was assessed at the ages of 3, 4, and 5 years. Latent growth curve models show that non-native German language children are characterized by reduced vocabulary at first assessment and lower progress compared to monolingual peers. Phonological working memory has a strong impact on all children's initial vocabulary but also on vocabulary growth in those whose parents speak German as an additional language. The effects of preschool and home learning environment are comparatively smaller.     

Using Human Givens therapy to support the well‐being of adolescents: a case example

This article outlines the use of Human Givens (HG) therapy with adolescents reporting poor subjective well‐being. HG therapy is based on the assumption that human beings have innate needs, which, if unmet, lead to emotional distress and mental health problems. Hitherto, there has been no independently published empirical research into the efficacy of HG as a therapeutic intervention with young people. The article examines the theory and background to HG therapy; the emotional well‐being of children; and young people and counselling and therapeutic interventions in schools, before describing an exploratory case study into the effectiveness of the HG approach. This involves assessing the efficacy of an individual HG intervention for three young people reporting high anxiety or depression and/or low self concept. The HG process and therapy structure are detailed through an illustrative case study regarding a 16‐year‐old girl with moderate levels of anxiety and low self‐concept. Positive outcomes are observed for all three young people, providing tentative evidence that HG therapy might be useful to practitioners delivering therapeutic interventions in schools, although limitations of the small‐scale research design are highlighted. Issues relating to the provision of individual therapeutic interventions in school are discussed more widely, as are other possible applications of the HG approach in schools.     

Do PDAs enhance the organization and memory skills of students with cognitive disabilities?

The project studied the on‐time behavior of 35 students with intellectual disabilities (ID) or traumatic brain injury (TBI) under three conditions – times and tasks list, paper planner, and two different personal data assistants (PDAs). Students participated for two 4‐week periods, receiving one morning reminder during Period 1 and no reminders during Period 2. Students were on time more often using a PDA compared to a list (p < .024) or a planner (p < .002). Students were on time 50% more often in Period 1 with a single daily morning reminder as compared to no reminder across all conditions. When applying results, clinicians and researchers should note that only the alarm function prompting on‐time behavior was studied, and the influence of the small sample size and short time frame. Future researchers will find a framework for studying PDAs and cell phones with larger samples, over longer time periods, and with a wider range of functions. © 2008 Wiley Periodicals, Inc.     

Psychologists in the schools of Nebraska: Professional functions

A survey of practicing school psychologists in the state of Nebraska was conducted to gather facts and opinions across a broad spectrum of topics. This article is based on one section of that survey which was concerned with profesional functions of the school psychologist. Five functions of the school psychologist were explored: Assessment, Consultation, Evaluation, Administration, and Intervention. Respondents were asked to rate a number of subactivities under each of these five major functions on a five-point scale in terms of importance. Each subactivity was rated from two Points of view: (a) the importance of the activity as the respordent perceived the ideal role of the school psychologist, and (b) the importance of the activity in the present job situation. Weekly time engaged in each subactivity was, recorded. Results indicate that Consultation was considered the most important function in both the hypothetical ideal situation and on the job, though a significantly greater amount of time was reported spent in Assessment.     

Internationalisation and distance education: a Hong Kong case study

The accelerating globalisation of world economic relations has been paralleled by a progressive internationalisation of higher education, including the use of distance education. But the modification of distance education materials and the provision of local tutorial support are only rarely undertaken, despite the fact that in social science and the humanities such materials are culturally saturated. This Hong Kong case study in teacher education examines the issues, describes the opportunities and difficulties involved, and argues that cultural adaptation merits a higher priority than at present.     

Mexican American and European American College Students' Beliefs About Causes,Cures, and Sources of Help for Anxiety

Mexican American and European American college students rated an empirically derived list of the causes, cures, and sources of help for anxiety. Main effects were obtained for ethnicity on ratings related to cures and one source of help for anxiety. There were also significant differences in ratings of cause and cure beliefs for anxiety between men and women. Level of acculturation, however, was not found to be related to ratings among the Mexican American participants.     

Changing attitudes: supporting teachers in effectively including students with emotional and behavioural difficulties in mainstream education

Pupils with emotional and behavioural difficulties (EBD) are often considered the most challenging group to manage within mainstream education. The challenges perceived by teachers may be due, in part, to negative attitudes towards this cohort of pupils, which may exacerbate feelings of inadequacy and impact negatively upon direct interactions with pupils. The current study comprised a combination of implicit (i.e. the Implicit Relational Assessment Procedure, IRAP) and explicit (The Opinions Relative to Mainstreaming Scale, ORMS) technologies to assess the attitudes of teachers (N = 25) and teachers in training (N = 20) towards pupils with EBD. When these attitudes proved to be negative (relative to typically developing pupils), the utility of a combined behaviour intervention (BI) and stress-management intervention (SMI), in conjunction with a series of pre and post measures, was examined. The IRAP results for teachers indicated that the SMI enhanced their implicit positivity towards pupils with EBD (EBD PUPIL) to a considerable extent (0.025-0.175), and this was greater than the impact recorded with the BI. The teachers in training showed implicit negativity towards EBD PUPIL (0.13) and this decreased, albeit marginally, at post-BI (0.05) and post-SMI (0.06). Significant differences were recorded in teachers’ general attitudes towards inclusion (p < 0.001) and efficacy (p < 0.008). Significant effects were recorded for teachers in training in relation to their attitudes towards having a child with EBD and having a previously excluded child with EBD in their classrooms (all ps < 0.001). For this latter group, reductions were also recorded in their levels of depression, anxiety and stress (p < 0.001) and there was an increase in their psychological flexibility (p < 0.001). The current results indicate that a range of positive implicit and explicit outcomes was associated with the current BI and SMI package in terms of fostering more effective inclusion of pupils with EBD in mainstream education.
