This study examined if the relative birth distribution of drafted under 18 (U18) Australian football (AF) players influenced their physical and anthropometric profile. Birthdate, physical (vertical jump, agility, 20m sprint, 20m multistage fitness test) and anthropometric (standing height, body mass) data were obtained from U18 players drafted into the Australian Football League between 2010 to 2013 (n = 212). Birth distribution did not change across quartile (χ23 = 5.09, P > 0.05) or half year (χ21= 2.50, P > 0.05). Physical and anthropometric profiles did not differ according to quartile or half year (P > 0.05). Relative birth distribution did not appear to influence draft success or physical/anthropometric profile. This study provides insight into a phenomenon not always observed in team sport.

UNLABELLED: Competition-specific conditioning for tournament basketball games is challenging, as the demands of tournament formats are not well characterized. PURPOSE: To compare the physical, physiological, and tactical demands of seasonal and tournament basketball competition and determine the pattern of changes within an international tournament. METHODS: Eight elite junior male basketball players (age 17.8 ± 0.2 y, height 1.93 ± 0.07 m, mass 85 ± 3 kg; mean ± SD) were monitored in 6 seasonal games played over 4 mo in an Australian second-division national league and in 7 games of an international under-18 tournament played over 8 days. Movement patterns and tactical elements were coded from video and heart rates recorded by telemetry. RESULTS: The frequency of running, sprinting, and shuffling movements in seasonal games was higher than in tournament games by 8-15% (99% confidence limits ± ~8%). Within the tournament, jogging and low- to medium-intensity shuffling decreased by 15-20% (± ~14%) over the 7 games, while running, sprinting, and high-intensity shuffling increased 11-81% (± ~25%). There were unclear differences in mean and peak heart rates. The total number of possessions was higher in seasonal than in tournament games by 8% (± 10%). CONCLUSIONS: Coaches should consider a stronger emphasis on strength and power training in their conditioning programs to account for the higher activity of seasonal games. For tournament competition, strategies that build a sufficient aerobic capacity and neuromuscular resilience to maintain high-intensity movements need to be employed. A focus on half-court tactics accounts for the lower number of possessions in tournaments.

Differences in physiological, physical, and technical demands of small-sided basketball games related to the number of players, court size, and work-to-rest ratios are not well characterised. A controlled trial was conducted to compare the influence of number of players (2v2/4v4), court size (half/full court) and work-to-rest ratios (4x2.5 min/2x5 min) on the demands of small-sided games. Sixteen elite male and female junior players (aged 15-19 years) completed eight variations of a small-sided game in randomised order over a six-week period. Heart rate responses and rating of perceived exertion (RPE) were measured to assess the physiological load. Movement patterns and technical elements were assessed by video analysis. There were ∼60% more technical elements in 2v2 and ∼20% more in half court games. Heart rate (86 ± 4% & 83 ± 5% of maximum; mean ± SD) and RPE (8 ± 2 & 6 ± 2; scale 1-10) were moderately higher in 2v2 than 4v4 small-sided games, respectively. The 2v2 format elicited substantially more sprints (36 ±12%; mean ±90% confidence limits) and high intensity shuffling (75 ±17%) than 4v4. Full court games required substantially more jogging (9 ±6%) compared to half court games. Fewer players in small-sided basketball games substantially increases the technical, physiological and physical demands.

Following the identification of a gap in the literature around reasons for contemporary women’s self-identification as ‘feminist’ (Swirsky & Angelone, 2015), this paper discusses an empirical study of an intergenerational group of contemporary Australian female teachers collaboratively designing English curriculum around girls’ media. The paper explores the group’s shared conversations around feminism, over a series of meetings, as we (teachers and researcher) plan curriculum and negotiate broader subject positions possible for girls and women. These contexts include the competing discourses of feminism and postfeminism and how these mediate texts chosen for study, our pedagogical approaches, and the ways we experience our own lives. In this study, we struggle to find a shared language, across generations, with which to work collaboratively in a community of practice committed to the critical study of media, but involving different individual orientations to ‘feminism’. This is a space in which impediments to the feminist study of girls’ media quickly emerge. The paper also serves as a reminder that feminist scholarship takes place in schools, as well as in the academy, and that the gender studies work teachers do in schools is potentially whole population work, worthy of keen attention in the gender studies academic mainstream.

Female journalists’ experiences of sexual harassment are barely documented in the literature about Australian news journalism despite evidence of its ongoing prevalence. There have been some stories of harassment detailed in autobiographies by female journalists and the occasional article in the mainstream media about individual incidents, but it wasn’t until 1996 that a union survey provided statistical evidence of an industry-wide problem. That Media, Entertainment and Arts Alliance survey found that more than half of the 368 female participants had experienced sexual harassment at work. In 2012, I conducted the largest survey of female journalists in Australia finding that there was an increased number of respondents who had experienced sexual harassment in their workplaces. In a bid to better understand female journalists’ experiences of sexual harassment, this paper analyses written comments made by survey participants in relation to key questions about harassment. It finds that most downplay its seriousness and do not make formal reports because they fear victimisation or retaliation. As a consequence, a culture of secrecy hides a major industry problem where many women believe they should work it out themselves and that harassment is the price they have to pay for working in a male-dominated industry.

Many athletes report using a wide range of special sports foods and supplements. In the present study of 77 elite Australian swimmers, 99% of those surveyed reported the use of these special preparations, with 94% of swimmers reporting the use of non-food supplements. The most popular dietary supplements were vitamin or mineral supplements (used by 94% of the group), herbal preparations (61%), and creatine (31%). Eighty-seven percent of swimmers reported using a sports drink or other energy-providing sports food. In total, 207 different products were reported in this survey. Sports supplements, particularly supplements presented as pills or other non-food form, are poorly regulated in most countries, with little assurance of quality control. The risk of an inadvertent "positive doping test" through the use of sports supplements or sports foods is a small but real problem facing athletes who compete in events governed by anti-doping rules. The elite swimmers in this survey reported that information about the "doping safety" of supplements was important and should be funded by supplement manufacturers. Although it is challenging to provide such information, we suggest a model to provide an accredited testing program suitable for the Australian situation, with targeted athlete education about the "sports safety" of sports supplements and foods.

Objective: Patellar tendon injury commonly presents as abnormal imaging with pain or abnormal imaging without pain. Normal imaging with pain has also been reported clinically, but little is known about the behavior of these tendons over time. This study investigated the behavior of tendons with normal imaging and pain over a volleyball season.

Design: Prospective study.

Setting: Institutional.

Participants: One hundred and one male and female volleyball players.

Main outcome measurements: At the beginning and end of the season ultrasound determined imaging status and the single leg decline squat test determined pain. The imaging and pain status at follow-up of tendons with normal imaging and pain at baseline was reported and contrasted to the imaging and pain status of the other patellar tendon injuries.

Results: Tendons with normal imaging and pain [relative risk (RR) 15.1], abnormal imaging without pain (RR 14.6), and abnormal imaging with pain (RR 51.5) had a greater risk of having abnormal imaging with pain at the end of the season when compared with normal tendons (P < 0.01). Among tendons with normal imaging and pain at baseline, 27% had abnormal imaging without pain and 21% contained abnormal imaging with pain at the end of the season.

Conclusions: Patellar tendons with normal imaging and pain at the beginning of a volleyball season are equally as likely to have abnormal imaging and pain at the end of the season as tendons with abnormal imaging without pain. Normal imaging with pain may represent a clinically relevant patellar tendon injury.

Purpose: The present paper is based on a cross-cultural exploration of middle managers in two diverse cultures and aims to focus on how the leadership styles of managerial women are perceived and evaluated. In particular, female and male peer evaluations of leadership effectiveness in Malaysia and Australia are to be explored.

Design/methodology/approach
: Surveys from 324 middle managers from Malaysia and Australia were quantitatively analysed. The sample for the study was drawn from organisations in four industry types in both countries.

Findings:  Findings suggest that evaluations of female managers' leadership styles in general, and within the respondent's own organisations, were strongly culture specific, especially in Malaysia. The results reflected the strongly held values, attitudes and beliefs of each country. While this is not unexpected, it does highlight a need to be cautious when interpreting Western research results and attempting to transplant those into other cultures. In Malaysia, female managers were not seen as effective in the leadership styles they adopted in their roles when compared to the Australian female managers' evaluations. Such an evaluation may have had little to do with an objective appraisal of the female managers' capability, but rather with a strongly held cultural belief about the appropriate role of women in society, and in organisations in particular.

Research limitations/implications
:  It is suggested that national culture manifests itself in the values, attitudes and behaviours of people. Cultural influences are therefore likely to impact on the way women and men behave in the workplace, particularly when roles of authority and power are evident, and the way in which that behaviour will be evaluated by others. Further research using different samples in different cultures are recommended. In addition, the influence of ethnicity, race or religion in plural countries such as Malaysia and Australia is also worthy of investigation.

Practical implications:  This research suggests that values and attitudes are strongly culture-specific and therefore have the ability to influence evaluations at an organisational level. Such an awareness of cultural influences should guide appropriate human resource practices, particularly within a globalized environment.

Originality/value:  The inclusion of a gender comparison in the data analysis in this paper is a significant attempt to add to the extant knowledge of the cross-cultural research. This is a unique contribution because of the omission of a gender perspective in the previous two seminal studies in culture literature (i.e. Hofstede and House et al.). In addition, the findings suggest that culture-specific influences are important determinants that impose expectations on the role of women differently from men in society and within organisations hence, making the gender comparison of the findings more significant.

The primary aim of this study was to develop and validate a golf-specific approach-iron test for use with elite and high-level amateur golfers. Elite (n=26) and high-level amateur (n=23) golfers were recruited for this study. The ‘Approach-Iron Skill Test’ requires players to hit a total of 27 shots. Specifically, three shots are hit at each of nine targets on a specially constructed driving range in a randomised order. A real-time launch monitor positioned behind the player, measured the carry distance for each of these shots. A scoring system was developed based on the percentage error index of each shot, meaning that 81 points was the maximum score possible (with a maximum of three points per shot). Two rounds of the test were performed. For both rounds of the test, elite-level golfers scored significantly higher than their high-level amateur counterparts (56.3±5.6 and 58.5±4.6 points versus 46.0±6.3 and 46.1±6.7 points, respectively) (P<0.05). For both elite and high-level players, 95% limits of agreement statistics also indicated that the test showed good test–retest reliability (2.1±7.9 and 0.2±10.8, respectively). Due to the clinimetric properties of the test, we conclude that the Approach-Iron Skill Test is suitable for further examination with the players examined in this study.

Development and implementation of a novel measure for quantifying training loads in rowing: The T2minute method. J Strength Cond Res 28(4): 1172–1180, 2014—The systematic management of training requires accurate training load measurement. However, quantifying the training of elite Australian rowers is challenging because of (a) the multicenter, multistate structure of the national program; (b) the variety of training undertaken; and (c) the limitations of existing methods for quantifying the loads accumulated from varied training formats. Therefore, the purpose of this project was to develop a new measure for quantifying training loads in rowing (the T2minute method). Sport scientists and senior coaches at the National Rowing Center of Excellence collaborated to develop the measure, which incorporates training duration, intensity, and mode to quantify a single index of training load. To account for training at different intensities, the method uses standardized intensity zones (T zones) established at the Australian Institute of Sport. Each zone was assigned a weighting factor according to the curvilinear relationship between power output and blood lactate response. Each training mode was assigned a weighting factor based on whether coaches perceived it to be “harder” or “easier” than on-water rowing. A common measurement unit, the T2minute, was defined to normalize sessions in different modes to a single index of load; one T2minute is equivalent to 1 minute of on-water single scull rowing at T2 intensity (approximately 60–72% V[Combining Dot Above]O2max). The T2minute method was successfully implemented to support national training strategies in Australian high performance rowing. By incorporating duration, intensity, and mode, the T2minute method extends the concepts that underpin current load measures, providing 1 consistent system to quantify loads from varied training formats.

Groin pain is a condition with a high prevalence in young Australian football players. It is considered that early identification of this condition allows for optimal management. Eighty-six players from two elite under-age Australian football sides were screened weekly for hip adductor muscle strength, using a hand-held dynamometer and for the onset of groin pain. The maximum variation in the average hip adductor muscle strength values of the sample was a 2.6% decrease from baseline in week 7 of the study. Twelve players (14% of the sample studied) reported groin pain for two consecutive weeks and were considered to have an onset of groin injury. The mean hip adductor muscle strength of these players was decreased significantly from baseline by an average of 11.75 ± 2.50% at the week of pain onset (F = 264.76 (1,11), p < 0.001), and 5.82 ± 5.16% in the week preceding the onset of pain (F = 14.03 (1,10), p = 0.004). These results confirm that hip adductor muscle strength is decreased both preceding and during the onset of groin injury in elite under-age Australian footballers.
