Mindfulness training attenuates the increase in salivary cortisol concentration associated with competition in highly trained wheelchair-basketball players

This study determined the effect of 8 wk of mindfulness training (MT) on salivary cortisol (sCort) and rate of salivary Immunoglobulin-A (sIgA) secretion in wheelchair-basketball players during a competition period. The mindful group completed 8 weeks of MT in addition to training and competition. sCort and rate of sIgA secretion were measured at baseline, at 2-week intervals, the end and 2 weeks following the intervention. A significant time and group interaction was observed for sCort (F = 3.297, P = 0.040, ES = 0.191); sCort increased in the control group from MT-BL to MT-2wk (P = 0.001) and remained significantly elevated at MT-4wk (P = 0.013) and MT-6wk (P = 0.002). sCort decreased from MT-6wk to MT-8wk (P < 0.001) and concentrations were not different at MT-8wk and Post-2wk to MT-BL (P > 0.05). Mindful group sCort increased from MT-BL to MT-2wk (P = 0.042) but decreased to concentrations no different to MT-BL for the rest of the intervention period (P > 0.05). There were no group differences in rate of sIgA secretion during the intervention (P = 0.810). It was concluded that 8 weeks of MT attenuated the increase in sCort associated with the competition period.     

Diurnal variation in cycling performance: influence of warm-up

We examined the effects of time of day on a cycling time trial with and without a prolonged warm-up, among cyclists who tended towards being high in "morningness". Eight male cyclists (mean +/- s: age = 24.9 +/- 3.5 years, peak power output = 319 +/- 34 W, chronotype = 39 +/- 6 units) completed a 16.1-km time trial without a substantial warm-up at both 07:30 and 17:30 h. The time trial was also completed at both times of day after a 25-min warm-up at 60% of peak power. Power output, heart rate, intra-aural temperature and category ratings of perceived exertion (CR-10) were measured throughout the time trial. Post-test blood lactate concentration was also recorded. Warm-up generally improved time trial performance at both times of day (95% CI for improvement = 0 to 30 s), but mean cycling time was still significantly slower at 07:30 h than at 17:30 h after the warm-up (95% CI for difference = 33 to 66 s). Intra-aural temperature increased as the time trial progressed (P < 0.0005) and was significantly higher throughout the time trials at 17:30 h (P = 0.001), irrespective of whether the cyclists performed a warm-up or not. Blood lactate concentration after the time trial was lowest at 07:30 h without a warm-up (P = 0.02). No effects of time of day or warm-up were found for CR-10 or heart rate responses during the time trial. These results suggest that 16.1-km cycling performance is worse in the morning than in the afternoon, even with athletes who tend towards 'morningness', and who perform a vigorous 25-min warm-up. Diurnal variation in cycling performance is, therefore, relatively robust to some external and behavioural factors.     

The role of number and spacing of CS-US pairings in conditioned suppression

In four studies, with rats as Ss. acquisition and. where appropriate, extinction trials were presented against a baseline of ongoing licking. At shock intensities of 0.1. 0.5. 1.0, or 2.0 mA, acquisition performance was a function of number of CS-US pairings: spacing of trials (one or two per day) did not affect acquisition performance. Resistance to extinction could be predicted from terminal acquisition performance and reached a maximum after three CS-US pairings.     

‘I'm going to feel stressed,but now I know how to handle it’: reducing test anxiety and improving student well-being at GCSE

Test anxiety has become a widespread issue in many contemporary societies, having a significant detrimental effect on the attainment, health and well-being of many young people. This paper evaluates a school-based, multimodal test anxiety intervention framework, ‘Every Little Helps’ (ELH), developed by educational psychologists and delivered to small groups of GCSE students (aged 15–16) in two secondary schools in the North West of England. A quasi-experimental, mixed methods approach was adopted. Findings suggest that ELH is helpful in reducing test anxiety amongst GCSE students. Participants report a range of helpful outcomes including an increased sense of control and competence through increased academic attainment, enhanced control of emotions and more helpful ways of thinking. Participants also report beneficial wider impacts as a result of being able to generalise learnt skills and techniques to other aspects of their lives. Implications for educational policy and practice and future research are considered.     

Pilot study evaluating the impact of dialogic reading and shared reading at transition to primary school: early literacy skills and parental attitudes

Previous studies have demonstrated the positive impact of shared reading (SR) and dialogic reading (DR) on young children's language and literacy development. This exploratory study compared the relative impact of parental DR and shared reading interventions on 4‐year‐old children's early literacy skills and parental attitudes to reading prior to and following school entry. Parents were trained using a self‐instruction training DVD. The children's rhyme awareness, word reading, concepts about print and writing vocabulary were assessed before and after 6 weeks over the summer period and again after one term in school. Four illustrative case studies are presented, which reveal the differential impact of the interventions on the families who participated. Findings indicated that DR had a positive impact on children's enjoyment of reading, concepts about print, parent–child reading behaviours and parental attitudes to joint storybook reading. The children who experienced shared‐book reading during the intervention also demonstrated improvements in word reading. There were no changes in rhyme awareness or writing vocabulary for either group. Changes in print concept awareness were not maintained at follow‐up, but improvements in writing vocabulary and word reading scores were noted. The reasons for this are discussed with reference to the formal literacy instruction the children received during their first academic term.     

Factors associated with physical activity referral uptake and participation

Abstract

The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (≥80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003 – 1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010 – 1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout.     

Biomechanical analysis of the change in pistol shooting format in modern pentathlon

Abstract

Despite the importance of the Combined Event to the modern pentathlon competition, little is known about performance in the event. This study aimed to (i) identify the key variables affecting Combined Event shooting performance, and the extent to which these corresponded with those identified for precision shooting and (ii) investigate the impact of changing shooting format, and whether more successful precision shooters were also more successful in the Combined Event. Seven modern pentathletes and three pistol shooters completed precision and Combined Event trials. An opto-electronic shooting system recorded score and pistol movements, whilst force platforms recorded centre of pressure movements 1 s prior to every shot. Intra-individual analysis revealed that the extent of associations between variables was participant-specific, highlighting the need for individual analysis of performance. No participants displayed matching associations between variables for precision and Combined Event shooting, emphasising the difference between performances in the two events. Both groups experienced significantly reduced scores, and increased pistol and body movements for Combined Event shooting (P < 0.05). Despite the pistol shooters’ greater precision shooting ability, no significant differences were evident between the groups’ Combined Event performances (P > 0.05). This implies that experience in one event does not guarantee success in the other, indicating the importance of event specific training.
