Screening for risk of low energy availability in athletic and recreationally active females in Ireland

ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.     

Movement and stretching imagery during flexibility training

Abstract

The aim of this study was to examine the effect of movement and stretching imagery on increases in flexibility. Thirty volunteers took part in a 4 week flexibility training programme. They were randomly assigned to one of three groups: (1) movement imagery, where participants imagined moving the limb they were stretching; (2) stretching imagery, where participants imagined the physiological processes involved in stretching the muscle; and (3) control, where participants did not engage in mental imagery. Active and passive range of motion around the hip was assessed before and after the programme. Participants provided specific ratings of vividness and comfort throughout the programme. Results showed significant increases in flexibility over time, but no differences between the three groups. A significant relationship was found, however, between improved flexibility and vividness ratings in the movement imagery group. Furthermore, both imagery groups scored significantly higher than the control group on levels of comfort, with the movement imagery group also scoring significantly higher than the stretching imagery group. We conclude that the imagery had stronger psychological than physiological effects, but that there is potential for enhancing physiological effects by maximizing imagery vividness, particularly for movement imagery.     

The Representation of Altruistic and Egoistic Motivations in Children’s TV Programming

A content analysis of children’s television examined the frequency with which behaviors were (a) driven by altruistic versus egoistic motivations, (b) performed by affable/surly characters, (c) rewarded/punished, and (d) present in content popular among different age groups (2–5, 6–11, and 12–17 years old). We found that portrayal patterns stressed the importance of egoistic motivations (particularly competence, autonomy, and relatedness) for older children. The findings are interpreted in line with logic underlying the model of intuitive morality and exemplars (MIME; Tamborini, 2013), suggesting that media representations can influence the motivations of their viewers.     

Effects of signaled reward in instrumental conditioning: Enhanced learning on DRL and DRH schedules of reinforcement

The effects of signaled reward were examined using DRL and DRH schedules of reinforcement. In each case, one group of rats received a brief cue between the reinforced response and the reward, and a second group received brief cues at random times. With the DRL schedule (Experiment 1), signaled reward decreased response rate, increased response efficiency (number of responses per reinforcer), and increased resistence to satiation relative to the control group. With the DRH schedule (Experiment 2), signaled reward increased response rate, efficiency, and resistance to satiation. These results refute an overshadowing explanation of the effects of signaled reward and suggest that food-correlated cues enhance learning of the reinforcement contingencies.

Landmark use by squirrel monkeys (Saimiri sciureus)

Two squirrel monkeys searched for a reward buried in 1 of 144 holes that formed a 12×12 grid (48×50 cm). An array of vertical, colored landmarks was placed on the grid, and their locations on the grid were changed from trial to trial. During training trials, the mealworm reward was placed either in the center of a square array of landmarks (Experiments 1 and 3) or midway between two landmarks (Experiment 2). On nonrewarded test trials, the monkeys searched among landmarks placed in the same arrays as those used in training and among landmarks placed in an expanded array (Experiments 1 and 2) or in an array intermediate between the two arrays used in training (Experiment 3). Distributions of searches on test trials indicated that the monkeys searched mostly within the configuration of the landmarks but that they had not coded the location of the reward as being either in the middle of the landmarks or at a fixed distance and direction from an individual landmark.     

Developing and sustaining a sense of place: The role of social information

This exploration of the role of information in helping people to develop and sustain feelings of belonging, or a sense of place, is based on a study that investigated the reasons for the high population turnover in the Northern Territory of Australia. The Northern Territory along with Darwin, its capital, has a number of unusual characteristics including geographical isolation. A key component of the theoretical framework for the research focuses on social information, which has similarities to the more commonly termed everyday life information. The specific concern is with the kind of information that helps people connect to a community and is clearly linked with social networking. The sample for the major empirical component for the article was recruited at Darwin's Mindil Beach Market. In telephone phone interviews with those who had agreed to participate, participants discussed how they learned about Darwin and the Northern Territory, and their views of Darwin as a place to live. Interpersonal contacts, including at the Market and at special events, were most often mentioned in relation to information, confirming literature findings on the importance of family and friends as an information source. Other sources were newspapers and physical markers around the City of Darwin. The conclusion is that the processes of social networking, which work well for some residents, could be enhanced through the use of information grounds, a concept widely discussed in the library and information science literature. Obvious information grounds in Darwin, where the usual processes could be enhanced by the distribution of information by formal information providers, include Mindil Beach Market and the special events for which Darwin is renowned.     

Macroappraisal Kiwi Style: Reflections on the Impact and Future of Macroappraisal in New Zealand

Both macroappraisal and the Australian records continuum-based DIRKS methodology have been influential in the New Zealand debate on appraisal in recent years. The primary influence of macroappraisal has been in the area of prioritisation of appraisal work. This paper considers New Zealand thinking on prioritisation, and the influences of risk management and functional analysis on this issue. A lack of agreement on the purpose of appraisal in the professional literature is noted, and some personal suggestions are offered on a model taking elements from macroappraisal and other methodologies.
