This thesis provides an examination of exercise dependence (EXD) among elite Australian athletes. The research identifies the main symptoms of EXD among elite athletes as excessive training, withdrawal, and continuance behaviours. EXD was found to be associated with irrational beliefs relating to training, low self esteem, and limited social support. The portfolio presents four case studies illustrating the use of solution focused brief counselling with athletes and drawing attention to the utility of a solution focused approach as an effective tool in sport psychology consultancy.

The aim of this study was to investigate the prerace and during-race carbohydrate intakes of elite-level triathletes contesting draft-legal Olympic-distance triathlon (ODT) events. Self-reported prerace and during-race nutrition data were collected at 3 separate ODT events from 51 elite senior and under-23 triathletes. One hundred twenty-nine observations of food and fluid intake representing actual prerace (n = 62) and during-race (n = 67) nutrition practices from 36 male and 15 female triathletes were used in the final analysis of this study. Female triathletes consumed significantly more carbohydrate on the morning before race start when corrected for body mass and race start time than their male counterparts (p < .05). Male and female triathletes consumed 26% more energy (kJ/kg) and 24% more carbohydrate (g/kg) when commencing a race after midday (1:00-1:30 p.m.) than for a late morning (11:00-11:15 a.m.) race start. During the race, triathletes consumed less than 60 g of carbohydrate on 66% of occasions, with average total race intakes of 48 ± 25 and 49 ± 25 g carbohydrate for men and women, respectively. Given average race times of 1:57:07 hr and 2:08:12 hr, hourly carbohydrate intakes were ∼25 g and ∼23 g for men and women, respectively. Although most elite ODT triathletes consume sufficient carbohydrate to meet recommended prerace carbohydrate intake guidelines, during-race carbohydrate intakes varied considerably, with many failing to meet recommended levels.

Objectives: To compare the skeletal benefits associated with gymnastics between ulna and radius.
Methods: 19 retired artistic gymnasts, aged 18-36 years, were compared to 24 sedentary women. Bone mineral content (BMC), total and cortical bone area (ToA, CoA), trabecular and cortical volumetric density (TrD, CoD) and cortical thickness (CoTh) were measured by pQCT at the 4% and 66% forearm.
Results: At the 4% site, BMC and ToA were more than twice greater at the radius than ulna whereas at the 66% site, BMC, ToA, CoA, CoTh and SSIpol were 20 to 51% greater at the ulna than radius in both groups (p<0.0001). At the 4% site, the skeletal benefits in BMC of the retired gymnasts over the non-gymnasts were 1.9 times greater at the radius than ulna (p<0.001), with enlarged bone size at the distal radius only. In contrast, the skeletal benefits at the 66% site were twice greater at the ulna than radius for BMC and CoA (p<0.01).
Conclusion: Whereas the skeletal benefits associated with long-term gymnastics were greater at the radius than ulna in the distal forearm, the reverse was found in the proximal forearm, suggesting both bones should be analysed when investigating forearm strength.

Bone strength benefits after long-term retirement from elite gymnastics in terms of bone geometry and volumetric BMD were studied by comparing retired female gymnasts to moderately active age-matched women. In a cross-sectional study, 30 retired female gymnasts were compared with 30 age-matched moderately active controls. Bone geometric and densitometric parameters were measured by pQCT at the distal epiphyses and shafts of the tibia, femur, radius, and humerus. Muscle cross-sectional areas were assessed from the shaft scans. Independent t-tests were conducted on bone and muscle variables to detect differences between the two groups. The gymnasts had retired for a mean of 6.1 ± 0.4 yr and were engaged in ≤2 h of exercise per week since retirement. At the radial and humeral shafts, cortical cross-sectional area (CSA), total CSA, BMC, and strength strain index (SSIpol) were significantly greater (13–38%, p ≤ 0.01) in the retired gymnasts; likewise, BMC and total CSA were significantly greater at the distal radius (22–25%, p ≤ 0.0001). In the lower limbs, total CSA and BMC at the femur and tibia shaft were greater by 8–11%, and trabecular BMD and BMC were only greater at the tibia (7–8%). Muscle CSA at the forearm and upper arm was greater by 15–17.6% (p ≤ 0.001) but was not different at the upper and lower leg. Past gymnastics training is associated with greater bone mass and bone size in women 6 yr after retirement. Skeletal benefits were site specific, with greater geometric adaptations (greater bone size) in the upper compared with the lower limbs.

While the results of nations in international sport competitions are most often used as an evaluation of effectiveness of elite sport policies, they do not take into account the long-term duration of an athletic career, nor the many confounding variables influencing international success. This paper argues that output evaluation is a one-sided approach to policy assessment. It applies a multidimensional approach to the measurement of the effectiveness of elite sports policy evaluation (meso-level) by examining a four-year cycle of elite sport policies in Flanders. This study endeavors to advance the development of a framework to assess effectiveness of elite sport policies of nations. Data were collected at multiple points of the input-throughput-output and feedback cycle. It was found that in spite of the increasing elite sport expenditures in Flanders (inputs), and notwithstanding the development of the throughputs (processes), this has not as yet lead to acceptable results (outputs) at an international level.

Running is the most important discipline for Olympic triathlon success. However, cycling impairs running muscle recruitment and performance in some highly trained triathletes; though it is not known if this occurs in elite international triathletes. The purpose of this study was to investigate the effect of cycling in two different protocols on running economy and neuromuscular control in elite international triathletes. Muscle recruitment and sagittal plane joint angles of the left lower extremity and running economy were compared between control (no preceding cycle) and transition (preceded by cycling) runs for two different cycle protocols (20-minute low-intensity and 50-minute high-intensity cycles) in seven elite international triathletes. Muscle recruitment and joint angles were not different between control and transition runs for either cycle protocols. Running economy was also not different between control and transition runs for the ow-intensity (62.4 ^ 4.5 vs. 62.1 ^ 4.0 ml/min/kg, p . 0.05) and high-intensity (63.4 ^ 3.5 vs. 63.3 ^ 4.3 ml/min/kg, p . 0.05) cycle protocols. The results of this study demonstrate that both low- and high-intensity cycles do not adversely influence neuromuscular control and running economy in elite international triathletes.

In this article, I draw on Judith Butler's notion of performativity to investigate the role of digital technologies in processes of gendered subjectification (or ‘girling’) in elite girls' education. Elite girls' schooling is a site where the potential of digital technologies in mediating student‐led constructions and explorations of ‘femininity’ sits alongside school‐produced digital media in the form of promotional texts, in which young femininity is regulated by discourses of ‘girl power’. Whilst such schools are well equipped with digital resources that might be utilised towards students' interrogation of how ‘femininity’ is understood, thus politicising the girling process, school‐produced digital media inscribe a more prescriptive picture of ‘who’ an elite school‐girl can ‘be’. Lyla Girls' Grammar School (LGGS) is an elite secondary school in Melbourne, Australia. I report on research undertaken at two institutional levels of LGGS: the ‘school’ level in which digital media representations of young women are produced by the school and the ‘classroom’ level, in which media education pedagogy includes interactive web conferencing software. The use of digital technologies in media education appeared to support student‐led construction and interrogation of femininities to some extent. I argue that this kind of student‐led girling is important in the context of more prescriptive school‐level girling practices.

Popular discourses concerning the relationship between gender and academic literacies have suggested that boys are lacking in particular, school-based literacy competencies compared with girls. Such discourses construct “gender” according to a binary framework and they obscure the way in which literacy and textual practices operate as a site in which gendered identities are constituted and negotiated by young people in multiple sites including schooling, which academic inquiry has often emphasized. In this paper I consider the school-based textual practices of young women attending an elite school, in order to explore how these practices construct “femininities”. Feminist education researchers have shown how young women negotiate discourses of feminine passivity and heterosexuality through their reading and writing practices. Yet discourses of girlhood and femininity have undergone important transformations in times of ‘girl power’ in which young women are increasingly constructed as successful, autonomous and sexually agentic. Thus young women’s reading and writing practices may well operate as a space in which new discourses around girlhood and femininity are constituted. Throughout the paper, I utilize the notion of “performativity”, understood through the work of Judith Butler, to show how textual practices variously inscribe and negotiate discourses of gender. Thus the importance of textual work in inscribing and challenging notions of gender is asserted. I argue that critical literacy is just as important, but perhaps no more guaranteed, within elite girls’ education as it is within boys’ education.

Public concern about popular culture’s sexualisation of women and girls is regularly voiced in the Australian media. Young women grow up against a backdrop of ‘raunch culture’ (Levy, 2005), which for some scholars represents a ‘new’ femininity (Gill, 2007), in which ‘hyper-sexual’ forms of (hetero)sexual expression are now expected of young women and girls, despite ostensibly being about choice and personal empowerment. In this article, I explore the constructions of girlhood and femininity amongst young women attending an elite, single-sex, private school in Melbourne, Australia. Elite schooling for girls is often associated with highly classed notions of (hetero)sexual modesty and propriety, epitomised in the reality television program Ladette to Lady. Here I consider how hyper-sexualities are configured within students’ constructions of themselves and others, and I explore their relationship to classed expectations of identity for privileged girls. I examine the role that classed norms of identity play in mediating these girls’ negotiations of hyper-sexualities.
