Fluid and electrolyte needs for preparation and recovery from training and competition

For a person undertaking regular exercise, any fluid deficit that is incurred during one exercise session can potentially compromise the next exercise session if adequate fluid replacement does not occur. Fluid replacement after exercise can, therefore, frequently be thought of as hydration before the next exercise bout. The importance of ensuring euhydration before exercise and the potential benefits of temporary hyperhydration with sodium salts or glycerol solutions are also important issues. Post-exercise restoration of fluid balance after sweat-induced dehydration avoids the detrimental effects of a body water deficit on physiological function and subsequent exercise performance. For effective restoration of fluid balance, the consumption of a volume of fluid in excess of the sweat loss and replacement of electrolyte, particularly sodium, losses are essential. Intravenous fluid replacement after exercise has been investigated to a lesser extent and its role for fluid replacement in the dehydrated but otherwise well athlete remains equivocal.     

Phonological difficulties in high-functioning dyslexics

Well compensated, high-functioning dyslexics, aged 18 years, whose reading ability had improved so that it was now within one standard deviation of the normal population mean were assessed on a range of phonological tasks. The dyslexics were compared with controls matched for age and academic attainment. A sizeable subgroup performed as well as controls on a word recognition test. However, they performed worse, in terms of accuracy, on nonword reading and spelling, and worse, in terms of speed, on spoonerisms, digit naming and speech rate. These results indicate that, even when word recognition ability has reached normal levels, a specific problem in subsyllabic phonology persists, and is demonstrable both in written and spoken language processing. Despite this specific difficulty, all the dyslexic participants were studying for university entrance exams and were expected to enter tertiary education.     

The Implications of Cognitive Style for the Management of Student‐Supervisor Relationships

Abstract There has been little research into thesis supervision despite numerous testimonies asserting its critical importance in higher education. From the studies which have been carried out, it is evident that there are two main issues contributing to student dissatisfaction and low completion rates. One is the feeling of isolation expressed by students. The second, and most widely reported, is the nature of the relationship between supervisor and student. This paper describes an innovative programme of supervision which helps resolve the first of these issues. It also reports a preliminary study into the allocation of students to supervisors on the basis of the cognitive styles of both parties. Although, at this stage, there is no clear‐cut evidence to demonstrate the benefits of a ‘matching’ approach, it is suggested that a focus on the interaction between student and supervisor, using qualitative methods, rather than on the individuals themselves, may prove fruitful.     

Stressed parents with infants: reassessing physical abuse risk factors.

OBJECTIVE: This study aimed to examine the relationship between a range of potentially adverse psychosocial and demographic characteristics identified in the immediate postpartum period and child physical abuse potential at 7 months. METHOD: Data collected as part of a randomized controlled trial of a nurse home visiting programme for vulnerable families with newborns was used. Women (181) were recruited in the immediate postpartum period. At 7 months, 151 participants were available for evaluation. Potential for child physical abuse was assessed using the Child Abuse Potential (CAP) Inventory. RESULTS: Significant risk indicators identified by univariate analysis were financial stress, elevated Edinburgh Postnatal Depression Scale (EPDS) scores, education level less than 10 years, concern regarding the provision of housing, and domestic violence characterized by verbal and social abuse. There was no association between child abuse potential and sole parenthood, poverty, young maternal age, history of childhood abuse, or psychiatric history. Two variables were found to be of independent significance using a logistic regression model; elevated EPDS and perceived difficulty "making ends meet." CONCLUSIONS: The findings indicate that perceived stress relating to finances, accommodation and relationships in the immediate postpartum period are associated with heightened child physical abuse potential at 7 months. Elevated EPDS in the early postpartum period is also a risk indicator. The outcome of this study suggests that perinatal assessment of child abuse risk is possible and simple and is related to perceived stressors at the time surrounding delivery. This is independent of a range of demographic variables traditionally thought to predict high risk.     

Introduction to the Special Issue: exclusion,expulsion and suspension of students with disabilities: advancing knowledge,preventing educational exclusion

The papers in this special issue are at the vanguard of advancing knowledge about school suspensions and exclusions and in establishing a critical evidence base which educational policy and school-based initiatives can access in efforts to re-enact meaningful inclusion for some of our most vulnerable students. Hosting and showcasing emerging knowledge in this space is an important role for JORSEN as a journal which promotes educational inclusion. This short editorial offers an overview of the papers included in this special issue and suggests common issues in the important emerging field of research into the educational exclusion and suspension of students with disabilities.     

A single bout of high-intensity interval exercise and work-matched moderate-intensity exercise has minimal effect on glucose tolerance and insulin sensitivity in 7- to 10-year-old boys

The purpose of this study was to assess the acute effect of high-intensity interval exercise (HIIE) and moderate-intensity exercise (MIE) on glucose tolerance, insulin sensitivity and fat oxidation in young boys. Eleven boys (8.8 ± 0.8 y) completed three conditions: 1) HIIE; 2) work-matched MIE; and 3) rest (CON) followed by an oral glucose tolerance test (OGTT) to determine glucose tolerance and insulin sensitivity (Cederholm index). Fat oxidation was measured following the OGTT using indirect calorimetry. There was no effect for condition on plasma [glucose] and [insulin] area under the curve (AUC) responses following the OGTT (P > 0.09). However, there was a “trend” for a condition effect for insulin sensitivity with a small increase after HIIE (P = 0.04, ES = 0.28, 9.7%) and MIE (P = 0.07, ES = 0.21, 6.5%) compared to CON. There was an increase in fat oxidation AUC following HIIE (P = 0.008, ES = 0.79, 38.9%) compared to CON, but with no differences between MIE and CON and HIIE and MIE (P > 0.13). In conclusion, 7- to 10-year-old boys may have limited scope to improve insulin sensitivity and glucose tolerance after a single bout of HIIE and MIE. However, fat oxidation is augmented after HIIE but not MIE.
