The development of phonological abilities and their relation to reading acquisition: case studies of six Finnish children.

1999

The relation between phonological abilities and reading acquisition and the interindividual variation in the development of different phonological manipulation skills were assessed for six 7-year-old Finnish nonreaders. Intensive time series data were collected by following the children for 13 months. Assessments were conducted every 4 weeks with five phonological manipulation tests. The results indicated gradual progress at the group level. However, analysis of the individual profiles indicated large interindividual variation in the rate of improvement and in the relation between different manipulation skills and reading acquisition.

Footprint Curvature in Spanish Women: Implications for Footwear Fit

2020

The incorrect adjustment of footwear produces alterations in the foot that affect quality of life. The usual measurements for shoe design are lengths, widths and girths, but these measures are insufficient. The foot presents an angle between the forefoot and the rearfoot in the transverse plane, which is associated with foot pronation, hallux valgus and metatarsus adductus. Here, we aimed at identifying the groups formed by the angulations between the forefoot and rearfoot using a sample of footprints from 102 Spanish women. The angle between the forefoot and rearfoot was measured according to the method described by Bunch. A cluster analysis was performed using the K-means algorithm. Footp…

Physical activity and motor competence (MC) have been considered to be closely related and prevent childhood obesity. The aim of the study was two-fold: to examine MC measured with two different tools in relation to individual, family, and environmental correlates and to investigate gender differences in MC. The Test of Gross Motor Development-Third Edition (TGMD-3) was administered to three- to seven-year-old children (n = 945), while the Körperkoordinationstest für Kinder (KTK) was also used for five- to seven-year-old children (n = 444). The parent questionnaire (n = 936) included questions about individual (e.g., participation in organized sports), family (e.g., parents’ education level…

Physical activity parenting (PAP) is consistently correlated with children’s physical activity (PA). Children’s perception of PAP has garnered little attention given that it mediates the relationship between PAP and child PA outcomes. This study aimed to examine 7–10-year-old children’s perspectives on PAP practices and how they relate to their motivational regulation of PA. A total of 79 children 7–10 years of age participated in 19 semi-structured focus group interviews. Through qualitative theory-guided content analysis, using frameworks of parenting dimensions and self-determination theory (SDT), we found that children’s perceptions of high responsiveness and low demandingness in PAP—ac…

Does shoe heel-to-toe drop have an influence on performance in downhill trail running?

2019

Trail running (TR) is characterized by sequences of uphill and downhill performed in a natural environment. Recently, studies investigated performance factors specific to TR. During a full race of ...

Purpose This study assessed the prevalence of physical and cognitive doping in recreational triathletes with two different randomized response models, that is, the Cheater Detection Model (CDM) and the Unrelated Question Model (UQM). Since both models have been employed in assessing doping, the major objective of this study was to investigate whether the estimates of these two models converge. Material and Methods An anonymous questionnaire was distributed to 2,967 athletes at two triathlon events (Frankfurt and Wiesbaden, Germany). Doping behavior was assessed either with the CDM (Frankfurt sample, one Wiesbaden subsample) or the UQM (one Wiesbaden subsample). A generalized likelihood-rati…

Breakdown of high-energy phosphate compounds and lactate accumulation during short supramaximal exercise.

1987

Muscle ATP, creatine phosphate and lactate, and blood pH and lactate were measured in 7 male sprinters before and after running 40, 60, 80 and 100 m at maximal speed. The sprinters were divided into two groups, group 1 being sprinters who achieved a higher maximal speed (10.07 +/- 0.13 m X s-1) than group 2 (9.75 +/- 0.10 m X s-1), and who also maintained the speed for a longer time. The breakdown of high-energy phosphate stores was significantly greater for group 1 than for group 2 for all distances other than 100 m; the breakdown of creatine phosphate for group 1 was almost the same for 40 m as for 100 m. Muscle and blood lactate began to accumulate during the 40 m exercise. The accumulat…

Socio-critical research on teaching physical education and physical education teacher education

2017

The purpose of this study is to systematically review the socio-critical research on teaching physical education (PE) and PE teacher education (PETE) between 1999 and 2014. The procedure followed a four-phase approach: (a) searching publications through four international databases; (b) meeting inclusion criteria; (c) refining selection to identify specifically research-based papers; and (d) expert searching based on the research team’s knowledge. The selection process yielded 23 articles mainly from Australia, New Zealand, the USA and Spain. Most of the research was authored collaboratively by male and female authors affiliated to universities. A lack of authorship shared with participant …

Abjection and alterity in the imagining of transgender in physical education and sport: a pedagogical approach in higher education

2014

In physical education (PE) and sports there is little theoretical and empirical knowledge about transgender people, and particularly, on how they are and can be imagined within this context. In this paper, we present and analyze a pedagogical activity based on the reading and discussion of a fictional representation of a transgender person within a group of undergraduate students of Sport Sciences. Our theoretical frame situates abjection and alterity as opposing concepts on a continuum. Results show several ways in which a transgender person is imagined by students, as well as constraints and possibilities for the pedagogical proposal to promote moral imagining of transgender. Students sit…

Forward acceleration of the centre of mass during ski skating calculated from force and motion capture data

2016

The purpose of this paper was to present and evaluate a methodology to determine the contribution of bilateral leg and pole thrusts to forward acceleration of the centre of mass (COM) of cross-country skiers from multi-dimensional ground reaction forces and motion capture data. Nine highly skilled cross-country (XC) skiers performed leg skating and V2-alternate skating (V2A) under constant environmental conditions on snow, while ground reaction forces measured from ski bindings and poles and 3D motion with high-speed cameras were captured. COM acceleration determined from 3D motion analyses served as a reference and was compared to the results of the proposed methodology. The obtained value…
