Concussion Incidence, Mechanism, and Perspectives Among Australian Elite Surfers: Implications for Medical Support and Safety Protocols.

The primary objective was to investigate the incidence of concussion and the associated mechanisms of injury in elite Australian surfers. The secondary objective was to investigate the current perspectives and behaviors related to experiencing concussion in surfing. A cross-sectional, retrospective, descriptive survey. Surfing Australia high-performance program. Forty nationally identified elite Australian surfing athletes. A retrospective survey collected information pertaining to participant demographics, concussion history, potential concussive symptoms, such as headache, neck pain, dizziness, or unusual fatigue, following a wipeout, and participants' perspectives on concussion. Investigating concussion incidence among elite Australian surfers compared with potential undiagnosed concussive episodes. Surfers with a history of diagnosed surfing-related concussion (DC) were compared with those with no history of a diagnosed surfing-related concussion (NDC). A total of 13 of 40 surfers had a DC, with "contact versus the water surface" identified as the primary mechanism. Both DC and NDC groups had a high frequency of concussive symptoms after a surfing wipeout with a total of 447 and 573 concussive symptom occurrences reported in the DC and NDC groups, respectively. Concern regarding the long-term impacts of concussion were reported in 25 of 40 surfers. The number of concussive symptoms reported by surfers who had not previously been diagnosed with concussion suggests that concussion may be underreported and underdiagnosed in elite surfing. This underscores the need for increased medical support, education, and improved safety protocols.

The importance of paddling to surfing performance: Insights from elite athletes, coaches, and performance support practitioners

Although paddling has been widely studied, there remains a limited understanding of how a surfer's paddling ability directly influences their wave-riding performance. Using an ecological approach, this study examined the importance of paddling to surfing performance from the perspective of elite Australian athletes, coaches, and performance support practitioners. Ten elite Australian surfing coaches, ten elite Australian surfing athletes, and eight performance support practitioners completed semi-structured interviews. This approach underscores the significance of incorporating experiential knowledge from coaches, athletes, and performance support practitioners, particularly in surfing where the nature of high-performance sport requires a multi-disciplinary approach and highlights the potential value of qualitatively exploring expert perspectives. Findings showed that all participants agree that paddling is an integral aspect of surfing performance despite not being directly scored in competition. The ecological dynamics approach provided a framework for understanding the function of paddling as a tool that enables surfers to exploit the affordances of the environment and support positive performance outcomes under highly variable conditions. The findings highlight the complexities of the performer-environment relationship in surfing and draw attention to the potential for improvements in surfing performance that may be elicited by enhancing a surfer's paddling ability. This study contributes to a growing body of sports science literature investigating paddling performance in surfers and underscores the importance of paddling to surfing performance.

Factors that influence mental health and well-being of high-performance athletes from Olympic or Paralympic sport who have transitioned out of national-level or international-level sport: a mixed methods approach

Transitioning out of elite sports can be a challenging time for athletes. To illuminate the gaps and opportunities in existing support systems and better understand which initiatives may have the...

Sleep patterns before and after competition: A real-world examination of elite athletes

ABSTRACT Good sleep before and after competitions is crucial to cognitive, physiological performance and recovery. Yet, elite athletes face a unique set of challenges when acquiring good sleep before and after competitions, and indeed commonly report sleep problems when it matters most. This study examined the sleep of elite athletes before and after competition compared to before and after free days. A total of 1808 unique nights of actigraphy (n = 1495) and sleep diary (n = 1335) data from elite Australian Football League and National Rugby League male athletes (N = 85, M-age = 24.4 ± 3.6) were collected and analysed using multi-level mixed models. On nights before competitions, athletes advanced sleep timings (p < .001, d = 0.63) and increased total sleep time (p < .001, d = 0.65) compared to nights before free days. On nights after competitions, athletes delayed sleep timings (p < .001, d = 1.64), reduced total sleep time (p < .001, d = 1.28), and had significantly worse quality sleep (p < .001, d = 0.71) compared to nights after free days. Sleep was especially worse following night competitions. While elite athletes and organisations may be implementing effective sleep strategies to optimise sleep the night before competitions, strategies to improve sleep after competitions may be lacking. We discuss potential factors contributing to this asymmetry and propose areas for research moving forward.

Hip Muscle Strength, Range of Motion, and Functional Performance in Young Elite Male Australian Football Players.

Hip and groin injuries are common in field sports such as football, with measurement of hip strength and range of motion (ROM) recommended for assessment of these conditions. We aimed to report hip strength, hip ROM, and functional task performance in young elite Australian football athletes. Cross-sectional study. Fifty-eight newly drafted Australian Football League athletes completed hip abduction, adduction, internal rotation, external rotation, and flexion strength testing with an adjustable stabilized or hand-held dynamometer. Hip internal rotation and external rotation, bent knee fall out, and ankle dorsiflexion ROM were also measured. Players completed hop for distance, side bridge, and star excursion balance functional tests. We compared findings between the dominant and nondominant limbs. We found small deficits unlikely to be clinically meaningful in the dominant limb for hip abduction and adduction strength, and a small deficit in the nondominant limb for external rotation strength and side bridge time. Athletes had lower hip internal rotation (mean difference 2.56°; 95% confidence interval, 0.87 to 4.26) and total rotation ROM (2.03°; 95% confidence interval, 0.06 to 4.01) on the dominant limb. There were no meaningful differences between dominant and nondominant limbs for hip strength, ROM, or functional tests. Our results may be used for benchmarking young male Australian football athletes when targeting optimal strength and returning from injury.

“I lied a little bit.” A qualitative study exploring the perspectives of elite Australian athletes on self-reported data

ObjectivesExplore the perceptions and experiences of elite Australian athletes’ engagement with reporting data in surveillance systems. DesignQualitative Descriptive. SettingSemi-structured interviews conducted using Zoom. ParticipantsWe recruited 13 elite Australian athletes competing at a national or international level for semi-structured interviews. Main outcome measuresAudio recordings were transcribed using DeScript, checked for errors and imported into QSR NVIVO. Thematic analysis using QSR NVIVO was used to determine key themes from transcripts. ResultsThematic analysis uncovered four key themes: ‘the paradox of reporting’, ‘data for data's sake’, ‘eyes on reporting’ and ‘athlete friendly reporting’. ConclusionAthletes perceived reporting as a burden and the athlete management system presented numerous technological difficulties which led to athletes to backfill data entries and compromise data accuracy. Athletes had little knowledge on how their data was used and managed and often received minimal feedback from staff accessing the data. Athletes were unaware of who has access to their data, which is of concern as sensitive information may be collected and athletes may be underage. As a result, many athletes chose to report dishonest data to avoid their performance being questioned.

A Pilot Study on the Impact of Menstrual Cycle Phase on Elite Australian Football Athletes.

The effect of the menstrual cycle on athlete performance, wellbeing and perceived exertion and fatigue is not well understood. Furthermore, it has not been investigated specifically in Australian Football athletes. This pilot study aimed to explore how naturally menstruating Australian Football athletes may be affected by menstrual cycle phase. The data collected from the routine monitoring of five naturally menstruating athletes (average menstrual cycle length of 28 ± 3 [SD] days) in one team (athlete age range 18–35 years) competing in the Women’s Australian Football League during the 2019 season were retrospectively analysed to compare performance (countermovement jump parameters and adductor squeeze pressure), perceived exertion, perceived fatigue and wellbeing (perceived sleep quality, stress and soreness) outcomes between the follicular and luteal phases. Performance, perceived exertion, stress and soreness did not appear to be affected by menstrual cycle phase (p > 0.17). However, perceived fatigue appeared to be significantly greater (p = 0.042) and sleep quality worse (p = 0.005) in the luteal phase. This pilot study suggests further research focusing on the effect of menstrual cycle phase on subjective fatigue and wellbeing is warranted.

Measuring the sports nutrition knowledge of elite Australian athletes using the Platform to Evaluate Athlete Knowledge of Sports Nutrition Questionnaire.

To evaluate the nutrition knowledge of elite Australian athletes, and to obtain feedback from sports dietitians on the Platform to Evaluate Athlete Knowledge of Sports Nutrition Questionnaires' (PEAKS-NQ) suitability. Sports dietitians from the National Institute Network across Australia recruited athletes to complete the online, 50-item PEAKS-NQ which contained two sections (General Nutrition and Sports Nutrition). Sports dietitians provided feedback on the PEAKS-NQ using a 14-item questionnaire (with two open-ended items). The main outcome measures were nutrition knowledge score and tool suitability (usefulness, acceptability and feasibility) scores. For knowledge scores, independent t-tests, ANOVA and Chi-square tests were used to evaluate differences between groups. Suitability was evaluated using descriptive statistics. Twelve sports dietitians from the National Institute Network in Australia recruited a convenience sample of 240 athletes (21.3 ± 4.3 years, 63.5% female, 63.3% competed internationally). Athletes scored 70.7 ± 10.5%, with better general vs sports nutrition knowledge. Females had higher overall scores (P < .001) with no differences for age or sport played. University-educated athletes scored higher than non-tertiary educated athletes (P=.004). Knowledge gaps were identified in fats (role and food sources), recovery nutrition and managing body composition. Sports dietitians rated suitability of PEAKS-NQ positively with complete agreement on 8 of 12 items. Athletes have greater understanding of general nutrition compared to sports nutrition concepts and may benefit from education on applying nutrition in sports-specific contexts. Sports dietitians' responses showed PEAKS-NQ was a highly acceptable, feasible and useful measure.

Comparisons of Daily Energy Intake vs. Expenditure Using the GeneActiv Accelerometer in Elite Australian Football Athletes.

Salagaras, BS, Mackenzie-Shalders, KL, Nelson, MJ, Fraysse, F, Wycherley, TP, Slater, GJ, McLellan, C, Kumar, K, and Coffey, VG. Comparisons of daily energy intake vs. expenditure using the GeneActiv accelerometer in elite Australian Football athletes. J Strength Cond Res 35(5): 1273-1278, 2021-To assess validity of the GeneActiv accelerometer for use within an athlete population and compare energy expenditure (EE) with energy and macronutrient intake of elite Australian Football athletes during a competition week. The GeneActiv was first assessed for utility during high-intensity exercise with indirect calorimetry. Thereafter, 14 professional Australian Football athletes (age, 24 ± 4 [SD] y; height, 1.87 ± 0.08 m; body mass, 86 ± 10 kg) wore the accelerometer and had dietary intake assessed via dietitian-led 24-hour recalls throughout a continuous 7 days of competition period (including match day). There was a significant relationship between metabolic equivalents and GeneActiv g·min-1 (SEE 1.77 METs; r2 = 0.64; p < 0.0001). Across the in-season week a significant difference only occurred on days 3 and 4 (day 3: energy intake [EI] EI 137 ± 31 kJ·kg-1·d-1; 11,763 ± 2,646 kJ·d-1 and EE: 186 ± 14 kJ·kg-1·d-1; 16,018 ± 1973 kJ·d-1; p < 0.05; d = -1.4; day 4: EI: 179 ± 44 kJ·kg-1·d-1, 15,413 ± 3,960 kJ·d-1 and EE: 225 ± 42 kJ·kg-1·d-1; 19,313 ± 3,072 kJ·d-1; d = -0.7). Carbohydrate intake (CI) was substantially below current sports nutrition recommendations on 6 of 7 days with deficits ranging from -1 to -7.2 g·kg-1·d-1 (p < 0.05), whereas daily protein and fat intake was adequate. In conclusion, the GeneActiv provides effective estimation of EE during weekly preparation for a professional team sport competition. Australian Footballers attempt to periodize dietary EI to varying daily training loads but fail to match expenditure on higher-training load days. Specific dietary strategies to increase CI may be beneficial to achieve appropriate energy balance and macronutrient distribution, particularly on days where athletes undertake multiple training sessions.

Diet Quality of Elite Australian Athletes Evaluated Using the Athlete Diet Index

While athletes’ nutrient intakes have been widely reported, few studies have assessed the diet quality of athletes. This is the first study to evaluate the diet quality of athletes using the purpose-built Athlete Diet Index (ADI). A convenience sample of 165 elite athletes from Australian sporting institutions completed the ADI online, with subsequent automated results provided to their respective accredited sports dietitians (ASDs). At the completion of athlete participation, ASDs (n = 12) responded to a range of survey items using a Likert scale (i.e., 1 = strongly agree to 5 = strongly disagree) to determine the suitability of the ADI in practice. Differences in ADI scores for demographics and sport-specific variables were investigated using independent t-tests, analysis of variance (ANOVA) and Bonferroni multiple comparisons. Spearman’s rank correlation was used to assess the association between total scores and demographics. The mean total ADI score was 91.4 ± 12.2 (range 53–117, out of a possible 125). While there was no difference in total scores based on demographics or sport-specific variables; team sport athletes scored higher than individual sport athletes (92.7 vs. 88.5, p < 0.05). Athletes training fewer hours (i.e., 0–11 h/week) scored higher on Dietary Habits sub-scores compared with athletes training more hours (≥12 h/week; p < 0.05), suggesting that athletes who train longer may be at risk of a compromised dietary pattern or less than optimal nutrition practices that support training. Most (75%) ASDs surveyed strongly agreed with the perceived utility of the ADI for screening athletes and identifying areas for nutrition support, confirming its suitability for use in practice.

Poor mental health outcomes in crisis transitions: an examination of retired athletes accounting of crisis transition experiences in a cultural context

ABSTRACT Up to 20% of retiring athletes continue to experience crisis transitions, characterised by a lack of adjustment, ongoing psychological distress, depression and low self-esteem. Crisis transitions remain under researched compared with transition difficulties, especially within cultural sport psychology. This study aims to explore crisis transitions and related psychological distress within a cultural context. The media is a site of cultural exploration, thus this study examines data from the Australian media: specifically, a two-part special of a current affairs programme (120 minutes of footage) that examined the crisis transitions of nine former elite Australian athletes. Data were analysed using inductive thematic analysis, located within a constructionist epistemology. The focus of analysis was on the broad repeated patterns of representation around experiences of and reasons for crisis transitions. Athletes depicted transitions predominately as difficult, invoking diagnostic language, including depression and substance abuse, to further constructions of transition distress. However, transition was also presented as a relief and an ongoing process, using varying constructions of choice in order to produce different versions of retirement. A range of themes were identified in accounting for these experiences during crisis transitions: sport was constructed as an addiction, inactivity partly related to lack of activities and self-worth was invoked, as well as constructions of abandonment by sporting organisations. The findings contribute to the cultural praxis of transitions and crisis transition literature by extending understanding around these experiences and resultant poor athlete mental health. Implications for career assistance programs and supporting retiring athletes are outlined.

Australian team sports athletes prefer dietitians, the internet and nutritionists for sports nutrition information.

To evaluate the information sources that are used and preferred by Australian athletes and to assess if preferences influence nutrition knowledge (NK). Elite and non-elite Australian team sport athletes, playing Australian football (AF), cricket, lawn bowls, soccer or hockey, were recruited via the sporting organisations' qualified sports dietitians or club presidents. Athletes completed one of two online, validated sports NK questionnaires. Frequency analysis on previous sources of advice, preferred sources of information and preferred type of support were assessed. Differences in NK scores (%) based on previous sources of dietary advice and preferences for obtaining information were assessed using t test or Mann-Whitney U test. Demographic and information source questions were completed by 410 athletes; 331 also completed NK questions. Athletes were mostly non-elite (76%) and AF players (79%). Forty-four per cent of athletes reported having previously received advice from a dietitian. Twenty per cent, 19% and 16% of athletes chose "dietitian," "internet" and "nutritionist" as their preferred source of nutrition information, respectively. Athletes preferred information on sports nutrition (35%), individual consultations (33%), and information on general healthy eating (33%), over cooking classes (4%) and group presentations (3%). There were no significant associations between preferred and previous information sources and NK scores. Australian athletes prefer dietitians, the internet and nutritionists for sports nutrition information. There is an interest in and need for access to a qualified sports dietitian and reputable internet-based nutrition information. Education programs and advice given to athletes need to be evaluated.

The Effects of the Removal of Electronic Devices for 48 Hours on Sleep in Elite Judo Athletes.

This study has shown that the removal of electronic devices for a period of two nights (48 hours) during a judo camp does not affect sleep quality or quantity or influence athletic or cognitive performance.

Sleep patterns and match performance in elite Australian basketball athletes.

To assess sleep patterns and associations between sleep and match performance in elite Australian female basketball players. Prospective cohort study. Seventeen elite female basketball players were monitored across two consecutive in-season competitions (30 weeks). Total sleep time and sleep efficiency were determined using triaxial accelerometers for Baseline, Pre-match, Match-day and Post-match timings. Match performance was determined using the basketball efficiency statistic (EFF). The effects of match schedule (Regular versus Double-Header; Home versus Away) and sleep on EFF were assessed. The Double-Header condition changed the pattern of sleep when compared with the Regular condition (F(3,48)=3.763, P=0.017), where total sleep time Post-match was 11% less for Double-Header (mean±SD; 7.2±1.4h) compared with Regular (8.0±1.3h; P=0.007). Total sleep time for Double-Header was greater Pre-match (8.2±1.7h) compared with Baseline (7.1±1.6h; P=0.022) and Match-day (7.3±1.5h; P=0.007). Small correlations existed between sleep metrics at Pre-match and EFF for pooled data (r=-0.39 to -0.22; P≥0.238). Relationships between total sleep time and EFF ranged from moderate negative to large positive correlations for individual players (r=-0.37 to 0.62) and reached significance for one player (r=0.60; P=0.025). Match schedule can affect the sleep patterns of elite female basketball players. A large degree of inter-individual variability existed in the relationship between sleep and match performance; nevertheless, sleep monitoring might assist in the optimisation of performance for some athletes.

Performance success or failure is influenced by weeks lost to injury and illness in elite Australian track and field athletes: A 5-year prospective study.

To investigate the impact of training modification on achieving performance goals. Previous research demonstrates an inverse relationship between injury burden and success in team sports. It is unknown whether this relationship exists within individual sport such as athletics. A prospective, cohort study (n=33 International Track and Field Athletes; 76 athlete seasons) across five international competition seasons. Athlete training status was recorded weekly over a 5-year period. Over the 6-month preparation season, relationships between training weeks completed, the number of injury/illness events and the success or failure of a performance goal at major championships was investigated. Two-by-two table were constructed and attributable risks in the exposed (AFE) calculated. A mixed-model, logistic regression was used to determine the relationship between failure and burden per injury/illness. Receiver Operator Curve (ROC) analysis was performed to ascertain the optimal threshold of training week completion to maximise the chance of success. Likelihood of achieving a performance goal increased by 7-times in those that completed >80% of planned training weeks (AUC, 0.72; 95%CI 0.64-0.81). Training availability accounted for 86% of successful seasons (AFE=0.86, 95%CI, 0.46 to 0.96). The majority of new injuries occurred within the first month of the preparation season (30%) and most illnesses occurred within 2-months of the event (50%). For every modified training week the chance of success significantly reduced (OR=0.74, 95%CI 0.58 to 0.94). Injuries and illnesses, and their influence on training availability, during preparation are major determinants of an athlete's chance of performance goal success or failure at the international level.

The Use of Compression Garments in Elite Australian Athletes: A Survey

1.1 Objective: The use of compression garments is becoming increasingly popular amongst athletes as a method to enhance performance and/or recovery from exercise. However, little is known about the specific uses of compression garments and the perception of their benefit amongst elite athlete populations, therefore, the current study aimed to gain an understanding of the use of compression garments in the elite athlete setting. 1.2 Methods: The current study surveyed 236 elite Australian-representative athletes (160 male, 76 female) across a range of 16 sports (AFL, athletics, basketball, boxing, canoe slalom, football, gymnastics, netball, power-lifting, rowing, rugby union, rugby league, sailing, swimming, volleyball, wheelchair basketball) including Olympians (n=42) and Paralympians (n=28) from the 2012 London Games. The current use of compression garments, including which garments the athlete’s own, how they are used, duration of wear and their perceived benefit was assessed. Further analysis was performed to assess the use of compression garments in athletes <20 years (n=116) versus athletes >20 years (n=120). 1.3 Results: The majority of athletes surveyed wear compression garments both during exercise and for post-exercise recovery 1-3 times per week. The most common duration for wearing compression garments was 1-4 hours following exercise (55% of athletes surveyed). The most common compression garments owned by athletes were long tights (89%), and 71% of athletes indicated that they sleep in their compression garments at least once per week. Mean ± SD for the benefit of compression tights for recovery (0= no benefit, 100 = definitely beneficial) was; 76.1 ± 17.4. There was a significantly greater perceived benefit of compression garments (p < 0.05) in athletes <20 years compared to athletes >20 years of age. 1.4 Conclusion: The majority of athletes surveyed perceived a benefit in wearing compression garments both during exercise and for recovery. The current study highlights the level of perceived importance of compression garments as a performance and recovery tool in an elite athlete population.

The Effect of an above Real Time Decision-Making Intervention on Visual Search Behaviour

The investigation of visual search strategies allows researchers to further understand expertise in sport. This research measured the visual search strategies of six elite Australian Football athletes during the course of a five-week speeded video decision-making training intervention. There were two athletes in each intervention group; normal speed and above real time video, and two athletes in the control group. Athletes were asked to watch a series of video clips of match-day footage and click on the screen where they would place the ball if in possession. Eye movements were collected at the pre-test, third training session, post-test and retention test. Results revealed that following training, regardless of video speed, the fixation duration became longer compared to those who had no video training. This significant finding falls in line with previous research. Furthermore, the above real time training group spent a longer duration fixating on the best option after the retention test, compared to other groups. These results provide a solid base for future research in sport to track changes in eye movements throughout training and learning.

Understanding sleep disturbance in athletes prior to important competitions

Anecdotally many athletes report worse sleep in the nights prior to important competitions. Despite sleep being acknowledged as an important factor for optimal athletic performance and overall health, little is understood about athlete sleep around competition. The aims of this study were to identify sleep complaints of athletes prior to competitions and determine whether complaints were confined to competition periods. Cross-sectional study. A sample of 283 elite Australian athletes (129 male, 157 female, age 24±5 y) completed two questionnaires; Competitive Sport and Sleep questionnaire and the Pittsburgh Sleep Quality Index. 64.0% of athletes indicated worse sleep on at least one occasion in the nights prior to an important competition over the past 12 months. The main sleep problem specified by athletes was problems falling asleep (82.1%) with the main reasons responsible for poor sleep indicated as thoughts about the competition (83.5%) and nervousness (43.8%). Overall 59.1% of team sport athletes reported having no strategy to overcome poor sleep compared with individual athletes (32.7%, p=0.002) who utilised relaxation and reading as strategies. Individual sport athletes had increased likelihood of poor sleep as they aged. The poor sleep reported by athletes prior to competition was situational rather than a global sleep problem. Poor sleep is common prior to major competitions in Australian athletes, yet most athletes are unaware of strategies to overcome the poor sleep experienced. It is essential coaches and scientists monitor and educate both individual and team sport athletes to facilitate sleep prior to important competitions.

Changes in Athletic Identity and Life Satisfaction of Elite Athletes as a Function of Retirement Status

The purpose of this study was to track changes in athletic identity and life satisfaction of elite athletes over time as a function of retirement status and the voluntariness of retirement decisions. Sixty-two elite Australian athletes from 3 different phases of their athletic careers were surveyed 5 years apart. Athletic identity was shown to decrease as athletes approached retirement. Athletes who retired voluntarily reported an increase in life satisfaction post-retirement. These findings support the need for athlete career education programs that emphasize autonomy and career planning.

Predicting attitude towards performance enhancing substance use: A comprehensive test of the Sport Drug Control Model with elite Australian athletes

This study presents a comprehensive examination of the Sport Drug Control Model via survey data of elite Australian athletes. A cross-sectional nationwide mail survey. A mail survey of 1237 elite Australian athletes was conducted. Structural equation modelling was employed to test the model. Morality (personal moral stance on performance-enhancing substances use), reference group opinion (perceived moral stance of reference group on performance-enhancing substances use) and legitimacy (perceptions of the drug testing and appeals processes) evidenced significant relationships with attitude towards performance-enhancing substances use, which in turn was positively associated with doping behaviour. The model accounted for 81% and 13% of the variance in attitude towards performance-enhancing substances use and doping behaviour, respectively. These findings validate the usefulness of the Sport Drug Control Model for understanding influences on performance-enhancing substances use. Nevertheless, there is a need to survey athletes representing a broader range of competition levels and cross-cultural research to test the model's applicability to other populations of athletes.
