Metabolic demand and muscle damage induced by eccentric cycling of knee extensor and flexor muscles

The aim of this study was to examine the metabolic demand and extent of muscle damage of eccentric cycling targeting knee flexor (FLEX) and knee extensor (EXT) muscles. Methods: Eight sedentary men (23.3?±?0.7?y) underwent two eccentric cycling sessions (EXT and FLEX) of 30?min each, at 60% of the maximum power output. Oxygen consumption (VO₂), heart rate (HR) and rated perceived exertion (RPE) were measured during cycling. Countermovement and squat jumps (CMJ and SJ), muscle flexibility, muscle soreness and pain pressure threshold (PPT) of knee extensor and flexor muscles were measured before, immediately after and 1–4 days after cycling. Results: FLEX showed greater VO₂ (+23%), HR (+14%) and RPE (+18%) than EXT. CMJ and SJ performance decreased similarly after cycling. Muscle soreness increased more after EXT than FLEX and PPT decreased in knee extensor muscles after EXT and decreased in knee flexor muscles after FLEX. Greater loss of muscle flexibility in knee flexor muscles after FLEX was observed. Conclusion: Eccentric cycling of knee flexor muscles is metabolically more demanding than that of knee extensors, however muscle damage induced is similar. Knee flexors experienced greater loss of muscle flexibility possibly due to increased muscle stiffness following eccentric contractions.     

The influence of trait meta-mood on subjective well-being in high school students: a random intercept cross-lagged panel analysis

Trait meta-mood refers to people’s conscious awareness of their own emotions. This reflexive process is relevant to developing a better adaptation to the environment, understanding the individual differences in how people perceive and attend to emotions, and how they can understand and regulate them in an optimal way. Previous research has indicated that trait meta-mood plays an important role in well-being. Accordingly, the main objective of this study was to analyse the prospective effects of trait meta-mood on levels of subjective well-being. A sample of 570 high school students (289 females), from 12 to 17 years (M?=?13.80, SD?=?1.45), completed measures of trait meta-mood, satisfaction with life, and positive and negative mood states across three waves separated by 1-year intervals. Random intercept cross-lagged panel analyses indicated that the dimensions of meta-mood accounted for a significant amount of variance in both cognitive and affective dimensions of well-being across time.     

Association of Gestational Diabetes Mellitus and Perinatal Maternal Depression with Early Childhood Behavioral Problems: An Environmental Influences on Child Health Outcomes (ECHO) Study

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only.     

Studies in mindfulness: widening the field for all involved in pastoral care

Abstract

Since 2010, the University of Aberdeen, Scotland, UK, has offered an MSc in studies in mindfulness degree programme within its School of Education. The programme has attracted over 200 students from multiple professional contexts, providing the authors with the opportunity to gather and analyse demographic data, as well as data regarding student motivations and expectations, both personal and professional. The paper initially creates a picture of the current UK ‘studies in mindfulness’ landscape by describing the established programmes at UK universities. Data from an entry questionnaire completed by three cohorts of students on the ‘Aberdeen’ programme and data collected from students throughout their studies is then presented, analysed and discussed. The authors argue that, in their professional roles, graduates from programmes and courses at Universities in the UK are introducing an ever-increasing number of people to mindfulness. They are implementing and integrating mindfulness into diverse social, business contexts as well as into all sectors of education. The University of Aberdeen’s programme, based in the School of Education, perhaps represents a move towards more holistic, pastoral and multi-professional applications of mindfulness. This contrasts with the clinical, pathological settings for mindfulness to date.     

The Effect of Pupil Cognitive Style and Position of Prose Passage Title on Recall

A replication of Bransford and Johnson's (1972) experiment on contextual prerequisites was carried out with the additional inclusion of cognitive styles as independent variables. A total of 77 10‐ and 11‐year‐old subjects (year 6, primary school) were asked to read a short prose passage on the topic of washing clothes. Half of the subjects were told the title of the passage before reading it and half after. All subjects attempted to free recall the passage. They had also completed the Cognitive Styles Analysis (CSA) (Riding, 1991), thus providing their position on the two fundamental cognitive style dimensions: Wholist‐Analytic and Verbal‐Imagery. It was found that the Wholist‐Analytic cognitive style and title‐passage order interacted in their effect on recall (p < 0.05). Whilst Wholists performed best when the title was presented before reading the passage, the order made no difference for other individuals. This suggested that this cognitive style reflects the way individuals organise information.     

Establishment of academic standards for early twentieth century Texas high schools: The university of Texas affiliated schools program

During the last quarter of the century several universities including those in Michigan, Illinois, and Texas launched initiatives to ensure that high schools’ academic standards prepared students for admission to the state university. This paper illuminates affiliation programs that foreshadowed the accreditation movement. Not only did affiliation serve the expectations of the universities, it also enabled high schools to emerge from their confused origins into increasingly stronger institutions.     

ICT, Education, and Visual Impairment

This paper provides an overview of developments in the use of information and communications technology (ICT) in the education of children with a visual impairment. The context is set by summarising the population of children with a visual impairment in this country, and presenting World Health Organisations classification of disability as a criteria by which the relevance of ICT can be measured. Case-studies of the use of different types of educational and access technology are presented and it is argued that information and communications technology has a valuable role in providing opportunities for children with a visual impairment to participate more fully in education.
