- Description: ‘Serious leisure’ cycling has developed as a reinterpretation of the traditional form of the sport. This short term, informal, unstructured and unconventional conceptualisation represents a challenge to participant numbers in the mainstream sport. The purpose of this study was twofold: (i) to ascertain the cultural, subcultural and ecological factors of participation in this new conceptualised form enabling clubs, associations and governments to a deeper understanding about participants practices and (ii) as an ongoing validation to previous qualitative work (see O’Connor and Brown, 2005). This study reports on the development and psychometric properties (principal components analysis, confirmatory factor analysis) of the Cyclists’ Motivation Instrument. Four hundred and twenty two cyclists (371 males, 51 females) who were registered members of the state competitive cycling body completed a fifty-one item instrument. Five factors were identified: social, embodiment, self-presentation, exploring environments and physical health outcomes and these accounted for 47.2% of the variance. Factor alpha coefficients ranged from .63 to .88, overall scale reliability was .92, suggesting moderate to high reliability for each of the factors and the overall scale.

- Description: Objectives: Sporting bodies have developed guidelines for managing community-level players with suspected concussion in response to international consensus statements on concussion in sport. The purpose of this study was to examine the factors that influence the intended use of concussion guidelines among community-level coaches and sports trainers from two popular football codes in Australia: Australian football and rugby league. Design: Cross-sectional survey. Methods: The survey, based on an extended theory of planned behaviour model, was completed by 183 Australian football coaches, 121 Australian football sports trainers, 171 rugby league coaches, and 142 rugby league sports trainers. Results: Personal norms and self-efficacy were significant predictors of intention to use concussion guidelines, although the relationship between self-efficacy and intention was stronger among Australian football coaches than rugby league coaches. Analysis of the salient beliefs that underpin self-efficacy found that coaches, irrespective of football code, felt less familiar (2 = 25.70, p < 0.001) and less experienced (2 = 31.56, p < 0.001) than sports trainers in using the concussion guidelines. At the same time, Australian football personnel, irrespective oftheir team role, feltthatthey had insufficienttime (2 = 8.04, p < 0.01) and resources (2 = 12.31, p < 0.001) to implement the concussion guidelines relative to rugby league personnel. Conclusions: Programmes aimed at increasing the intended use of sport concussion guidelines should focus on enhancing self-efficacy and leveraging personal norms. Increasing coaches’ familiarity and experience in using the concussion guidelines would also be warranted, as would finding ways to overcome the perceived time and resource constraints identified among Australian football personnel.

- Description: This study explored the measurement and use of internal and external imagery perspectives during imagery of open and closed sports skills. Participants (N = 41; male = 23; female = 18), ages 14 to 28 (M = 19.4 yr.; SD = 3.1), who were recruited from undergraduate classes in human movement and physical education, and local sporting teams, completed the Imagery Use Questionnaire and then imagined performing eight common sports skills, four open skills and four closed skills, in a random order. Participants provided concurrent verbalisation during their imagery. Immediately after imagining each skill, participants completed a rating scale and retrospective verbalisation of imagery perspective use. Analysis indicated that the questionnaire gave a general imagery perspective preference but was not a strong predictor of imagery used on specific occasions. The three measures of imagery perspective were equivalent in imagining performing particular skills. Participants experienced more internal imagery than external imagery while imagining the eight sports skills, but there was no significant difference between perspective use on the open and closed skills. © Perceptual and Motor Skills 2007.

- Description: Background: Prevention of sport injuries is crucial to maximise the health and societal benefits of a physically active lifestyle. To strengthen the translation and implementation of the available evidence base on effective preventive measures, a range of potentially relevant strategies should be considered. Objective: Our aim was to identify and categorise intervention strategies for the prevention of acute sport injuries evaluated in the scientific literature, applying the Haddon matrix, and identify potential knowledge gaps. Methods: Five electronic databases were searched (PubMed, EMBASE, SPORTDiscus, CINAHL, Cochrane) for studies that evaluated the effect of interventions on the occurrence of acute sport injuries. Studies were required to include a control group/condition, prospective data collection, and a quantitative injury outcome measure. Results: A total of 155 studies were included, mostly randomised controlled trials (43%). The majority of studies (55%) focussed on strategies requiring a behavioural change on the part of athletes. Studies predominantly evaluated the preventive effect of various training programmes targeted at the ‘pre-event’ phase (n = 73) and the use of equipment to avoid injury in the ‘event phase’ (n = 29). A limited number of studies evaluated the preventive effect of strategies geared at rules and regulations (n = 14), and contextual modifications (n = 18). Studies specifically aimed at preventing re-injuries were a minority (n = 8), and were mostly related to ankle sprains (n = 5). Conclusions: Valuable insight into the extent of the evidence base of sport injury prevention studies was obtained for 20 potential intervention strategies. This approach can be used to monitor potential gaps in the knowledge base on sport injury prevention. © 2017, The Author(s).

- Description: This paper examines whether involvement in an observational study may prompt participants to change their exercise behaviors. Data was collected from 394 older community dwellers in Victoria, Australia using a baseline survey, and 245 of these participated in a follow-up survey one year later. Survey domains were drawn from constructs of relevant health behavior models. Results showed that the proportion of respondents who were currently participating in exercises to prevent falls at follow-up was 12% higher than at baseline (Wilcoxon p value<0.001). Twenty-nine percent reported they had changed their perceptions about falls and their risk of falls, with comments focused on threat appraisal. Forty-four percent reported having taken strategies to reduce their risk of falling, with comments based on implementation of different preventive strategies. Respondents who held favorable views towards exercises for the prevention of falls appear to change their behaviors that might address falls when participating in observational studies.

- Description: Researchers who examine existing models of choking under pressure are beginning to explore the antecedents that predispose individuals to increased anxiety. Irrational beliefs (IBs) may be one such antecedent to “choking”, given that irrational beliefs are closely associated with anxiety intensity. This study aimed to investigate whether IBs influenced anxiety and performance under pressure. Experienced Australian football players (N = 35) completed an IBs questionnaire prior to an Australian football set shot experiment with low- and high-pressure. During both pressure conditions, participants completed a state anxiety questionnaire prior to completing 15 set shots on goal. Results indicated that cognitive and somatic anxiety increased from low- to high-pressure. For somatic anxiety, an IBs main effect approached significance, indicating higher somatic anxiety with increases in IBs. A marginally significant Condition main effect was found for performance, which decreased from low- to high-pressure, with no other effects for performance evident. Follow-up correlation analysis of seven athletes who likely experienced choking (i.e., greater than 15-point performance decrease) indicated a strong negative correlation between IBs and change in performance from low- to high-pressure. Further analyses for “chokers” indicated a significant IBs × Condition interaction, with performance tending to increase with increasing IBs under low-pressure and decrease with increasing IBs under high-pressure. This study provides initial, tentative support that IBs associated with performance trends of “chokers” under different pressure conditions may be dissimilar to those of “underperformers” or “clutch” performers. Applied implications for sport psychologists working with athletes are discussed. Lay summary: This paper investigated whether inflexible thoughts (i.e., irrational beliefs- IBs) led to increased anxiety and “choking”. Athletes completed an IBs questionnaire, then an anxiety survey during a football kicking task under low- and high-pressure. Results indicated IBs may affect “chokers” response to pressure differently to other groups. © 2020 Association for Applied Sport Psychology.

- Description: Objectives: To evaluate strength and flexibility measures pre- and post- Australian Football (AF) competition to determine their potential utility as secondary prevention measures. Design: Cohort study. Setting: Semi-professional AF club. Participants: Ten male AF athletes (mean ± SD; age, 21.3 ± 2.2 years; height, 186.1 ± 6.3 cm; weight, 83.5 ± 8.6 kg). Main Outcome Measures: Maximal unilateral isometric knee flexion strength performed in 45 degrees of hip flexion and 30 degrees of knee flexion, flexibility measures of hip and knee extension and ankle dorsiflexion. All outcome measures were evaluated pre-match to determine baseline measurements and repeated acutely post-match and at 26, 50 and 74 h following. Comparisons were made between baseline measures and all other time points. Results: Knee flexion strength was significantly reduced at a group level acutely (−122.8N, 95%CI −156.2 to −89.4, p = 0.000) and at 26 h (−89.6N, 95%CI −122.9 to −56.2, p = 0.000) following competition. Hamstring flexibility was significantly reduced at all time periods following competition (all p < 0.05), however these values were not clinically meaningful. Conclusions: Knowledge that unilateral isometric knee flexion strength returns to pre-competition levels by 50 h following match-play in AF athletes is valuable for planning recovery time frames and may inform implementation of secondary prevention strategies. © 2018 Elsevier Ltd

- Description: In sports injury prevention field trials, data collectors are often club volunteers with considerable knowledge of the game but with limited detailed medical backgrounds or knowledge of formal scientific processes. The aim of this paper is to determine the agreement among trained primary data collectors (PDCs) with a sport science background and no prior involvement in data collection in a large randomised controlled trial. During the 'Preventing Australian Football Injury through eXercise' (PAFIX) project, player participation and injury data were collected by trained PDCs at training and games over the 2007 and 2008 playing seasons in 40 community level Australian football teams. PDC-collected data relating to player exposure and whether or not a player sustained an injury and subsequently left the field of play was compared to the same information from independent observers (IOs) who attended one randomly selected game for each of the 40 teams. There was 98% agreement between the PDC and the IO on game details (i.e., date, time, grade and score), 79% (ICC 0.9, 95% CI 0.85-0.95) agreement on the number of players per game and 76% (ICC 0.8, 95% CI 0.69-0.91) agreement on the number of injuries sustained in the games. There was 100% agreement on whether the player left the field for all injuries. This study found that exercise and sport science students are reliable data collectors in sports injury fieldwork studies. (C) 2010 Sports Medicine Australia. Published by Elsevier Ltd.

- Description: This short report describes a 20-month follow-up of safe diving skills, extending the 8-month retention period previously published in this journal. Thirty-four recreational swimmers with poor diving skills were evaluated before and immediately after a diving skills intervention program. Twenty-two returned for the eight-month follow-up evaluation and 16 returned 20 months post. As with the earlier study, Treadwater, Deck, Block and Running dives were video-recorded, and maximum depth, distance, velocity, entry angle and flight distance were compared. Underwater hand and arm positions were examined. Pre-intervention, a breaststroke arm action before maximum depth occurred in 18% of all dives and 38% of Treadwater dives. This was eliminated post-intervention, improving head protection. The Treadwater dive elicited the greatest mean maximum depth, and ANOVA showed depth for this entry decreased (improved) following intervention and remained shallower at the eight-month and 20-month post follow-ups. The Block dive also became shallower following intervention while the Deck dive remained unchanged. As seven 10-minute skills sessions resulted in shallower dives with safer hand and arm positions, and these skills were retained over a 600 day non-practice period, it is reliable to consider that the inclusion of safe diving skills in learn-to-swim programs can provide a diving spinal cord injury prevention strategy.

- Description: Sporting clubs are an ideal setting to promote community-wide participation in physical activity. Using the principles of the Ottawa Charter as a guide, this study explored the factors affecting the development of supportive environments as a mechanism to increase participation in club sport. The Victorian Health Promotion Foundation (VicHealth) funds State Sporting Associations (SSAs) to develop healthy and welcoming environments (HWE) in their associated clubs. The program focus areas are: welcoming and inclusive environments, sports injury prevention, 'smoke-free' environments, responsible serving of alcohol, sun protection and healthy eating. This paper sought to determine whether or not SSA Executive Officers (EOs) believe that the creation of a supportive environment will facilitate sporting club membership and to identify the factors that affect the development of the HWEs. Forty-two (82.4%) of the 51 funded SSAs completed a general survey and 36 (70.6%) of EOs responded to questions that were specifically addressed to them. EOs from six SSAs also participated in semi-structured interviews. SSA EOs (97.2%) believed that the creation of HWE in clubs would facilitate increases in participant membership. However, the data indicate incomplete development of the HWE focus areas at the club level because of limited club capacity and limited SSA support. Reportedly, the SSAs are at the stage of raising program awareness at the club level. It is suggested that SSAs should plan a structured approach to the development of HWEs that acknowledges the diverse capacity of their clubs, and garner the support of key club volunteers in order to establish HWEs.

- Description: Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤ 0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥ 0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed. © 2010 Sports Medicine Australia.

- Description: Objective: In recent reports, Australian football has outranked other team sports in the frequency of hospitalizations and emergency department (ED) presentations. Understanding the profile of these and other "medical-attention" injuries is vital for developing preventive strategies that can reduce health costs. The objective of this review was to describe the frequency and profile of Australian football injuries presenting for medical attention. Data Sources: A systematic search was carried out to identify peer-reviewed articles and reports presenting original data about Australian football injuries from treatment sources (hospitals, EDs, and health-care clinics). Data extracted included injury frequency and rate, body region, and nature and mechanism of injury. Main Results: Following literature search and review, 12 publications were included. In most studies, Australian football contributed the greatest number of injuries out of any sport or recreation activity. Hospitals and EDs reported a higher proportion of upper limb than lower limb injuries, whereas the opposite was true for sports medicine clinics. In hospitals, fractures and dislocations were most prevalent out of all injuries. In EDs and clinics, sprains/strains were most common in adults and superficial injuries were predominant in children. Most injuries resulted from contact with other players or falling. Conclusions: The upper limb was the most commonly injured body region for Australian football presentations to hospitals and EDs. Strategies to prevent upper limb injuries could reduce associated public health costs. However, to understand the full extent of the injury problem in football, treatment source surveillance systems should be supplemented with other datasets, including community club-based collections. © 2014 Wolters Kluwer Health, Inc.

- Description: Sports and physical activity are transforming, and being transformed by, the societies in which they are practised. From the perspectives of both competitive and non-competitive sports, the complexity of their integration into today's society has led to neither sports federations nor governments being able to manage the safety problem alone. In other words, these agencies, whilst promoting sport and physical activity, deliver policy and practices in an uncoordinated way that largely ignores the need for a concurrent overall policy for sports safety. This article reviews and analyses the possibility of developing an overall sports safety policy from a global viewpoint. Firstly, we describe the role of sports in today's societies and the context within which much sport is delivered. We then discuss global issues related to injury prevention and safety in sports, with practical relevance to this important sector, including an analysis of critical policy issues necessary for the future development of the area and significant safety gains for all. We argue that there is a need to establish the sports injury problem as a critical component of general global health policy agendas, and to introduce sports safety as a mandatory component of all sustainable sports organizations. We conclude that the establishment of an explicit intersection between science and policy making is necessary for the future development of sports and the necessary safety gains required for all participants around the world. The Safe Sports International safety promotion programme is outlined as an example of an international organization active within this arena. © 2008 Adis Data Information BV. All rights reserved.

- Description: The purpose of this study was to determine if there is an association between variables that describe movements in an Australian Rules football (ARF) game with muscle damage. Fourteen elite junior ARF players were monitored with a global positioning system (GPS) during a match, and muscle damage was estimated by determining creatine kinase (CK) 24 hours postmatch. The players were median split based on CK levels, into a high and low CK group, and the groups were compared with independent t-tests. The primary finding was that the group that experienced greater muscle damage (high CK group) generally covered significantly (p < 0.05) greater distances. This was the case for running speeds between 4 and 7 m·s -1 and, with the exception of high acceleration, all intensities of acceleration and deceleration. The high, as compared with the low, CK group also produced a significantly greater (42%) "player load." All of these significant differences were accompanied by large effect sizes. Group-specific Pearson (r) correlations between CK level and GPS variables suggest that a certain volume of movement is required before the elicitation of a positive relationship beyond trivial or small. Correlations between CK and running speeds >4 m·s -1 and moderate-high acceleration and deceleration were negative in the low CK (lesser volumes) group. With the exception of low-intensity acceleration/deceleration, the same relationships were positive and generally of a moderate-to-large magnitude in the high CK (greater volumes) group. It may be that a certain volume of movement is required for that movement to be strongly associated with CK levels. It was concluded that selected GPS variables obtained from ARF games can be used as indicators of muscle damage, and this information may be used to individualize recovery strategies after games. © 2012 National Strength and Conditioning Association.

- Description: Objectives: To assess the association between workload, subjective wellness, musculoskeletal screening measures and non-contact injury risk in elite Australian footballers. Design: Prospective cohort study. Methods: Across 4 seasons in 70 players from one club, cumulative weekly workloads (acute; 1 week, chronic; 2-, 3-, 4-week) and acute:chronic workload ratio’s (ACWR: 1-week load/average 4-weekly load) for session-Rating of Perceived Exertion (sRPE) and GPS-derived distance and sprint distance were calculated. Wellness, screening and non-contact injury data were also documented. Univariate and multivariate regression models determined injury incidence rate ratios (IRR) while accounting for interaction/moderating effects. Receiver operating characteristics determined model predictive accuracy (area under curve: AUC). Results: Very low cumulative chronic (2-, 3-, 4- week) workloads were associated with the greatest injury risk (univariate IRR = 1.71–2.16, 95% CI = 1.10–4.52) in the subsequent week. In multivariate analysis, the interaction between a low chronic load and a very high distance (adj-IRR = 2.60, 95% CI = 1.07–6.34) or low sRPE ACWR (adj-IRR = 2.52, 95% CI = 1.01–6.29) was associated with increased injury risk. Subjectively reporting “yes” (vs. “no”) for old lower limb pain and heavy non-football activity in the previous 7 days (multivariate adj-IRR = 2.01–2.25, 95% CI = 1.02–4.95) and playing experience (>9 years) (multivariate adj- IRR = 2.05, 95% CI = 1.03–4.06) was also associated with increased injury risk, but screening data were not. Predictive capacity of multivariate models was significantly better than univariate (AUCmultivariate = 0.70, 95% CI 0.64–0.75; AUCunivariate range = 0.51–0.60). Conclusions: Chronic load is an important moderating factor in the workload–injury relationship. Low chronic loads coupled with low or very high ACWR are associated with increased injury risk.

- Description: Background: Nordic walking (NW) is a potentially beneficial exercise strategy for overweight and obese people. To date, no reviews have synthesized the existing scientific evidence regarding the effects of NW on this population. This systematic review and meta-analysis aimed to identify the characteristics, methodological quality, and results of the investigations that have studied the effects of NW in overweight and obese individuals. Methods: Six electronic databases were searched up to June 2019 for studies that examined the effects of NW on people with a body mass index ≥ 25 kg/m2. The methodological quality of the included randomized controlled trials was retrieved from the physiotherapy evidence database or evaluated using the physiotherapy evidence database scale. Results: Twelve studies were included in the review. The investigations were mostly good-to-fair methodological quality. NW groups had a significant improvement on parameters such as fasting plasma glucose, abdominal adiposity, and body fat compared with the baseline, but no significant improvements were found when compared with control groups. Conclusions: NW can potentially lead to improvements in parameters related to major health outcomes in overweight and obese people. The lack of control for confounding variables in the analyzed studies prevents further elaboration on its potential benefits. © 2020 Human Kinetics, Inc.

- Description:
The purpose of this study was to determine the relationships between selected physical qualities, change-ofdirection (COD) speed, and defensive agility performance in Australian Rules football players. Twenty-four male communitylevel players were assessed on sprint acceleration (10-m time), maximum strength (3 repetition-maximum half squat), leg power (countermovement jump), reactive strength (drop jump), and a single COD speed test and a defensive agility test. Change-of-direction speed was correlated with reactive strength (r = 20.645, p = 0.001) and sprint acceleration (r = 0.510, p = 0.011). Multiple regression indicated that the combined physical qualities explained 56.7% of the variance associated with COD speed (adjusted R
2 = 0.567, p ≤ 0.05). Participants were median split into faster and slower COD speed groups, and these were compared by independent t-tests. The faster group was significantly better (p ≤ 0.05) on the sprint acceleration and reactive strength tests (large effect size). The correlations between physical qualities and agility were trivial to small (r = -0.101 to 0.123, p > 0.05) and collectively explained only 14.2% of the variance associated with agility performance (adjusted R2 = -0.142, p > 0.05). When faster and slower agility groups were compared, there were trivial to moderate differences (p > 0.05) in all physical qualities. It was concluded that reactive strength and sprint acceleration are important for COD speed, but the physical qualities assessed are not associated with defensive agility performance. For agility tasks similar to those in this study, sprint and resistance training should not be emphasized, and training other factors, such as the development of sportspecific technique and cognitive skill, is recommended. © 2015 National Strength and Conditioning Association.

The faster group was significantly better (p ≤ 0.05) on the sprint acceleration and reactive strength tests (large effect size). The correlations between physical qualities and agility were trivial to small (r = -0.101 to 0.123, p > 0.05) and collectively explained only 14.2% of the variance associated with agility performance (adjusted R2 = -0.142, p > 0.05). When faster and slower agility groups were compared, there were trivial to moderate differences (p > 0.05) in all physical qualities. It was concluded that reactive strength and sprint acceleration are important for COD speed, but the physical qualities assessed are not associated with defensive agility performance. For agility tasks similar to those in this study, sprint and resistance training should not be emphasized, and training other factors, such as the development of sportspecific technique and cognitive skill, is recommended. © 2015 National Strength and Conditioning Association.

- Description: A purpose of this study was to determine if pre-season anthropometric and physiological measures were significantly different for the players from one Australian Football League (AFL) club selected to play in the first game of the season compared to the players not selected. Another purpose was to compare fitness test results for defenders, forwards and mid-fielders in the same AFL club. Thirty-four players were tested for isolated quadriceps and hamstrings strength, leg extensor muscle strength and power, upper body strength, sprinting speed, vertical jump (VJ), endurance, skinfolds and hamstring flexibility. The starters who were selected to play the first game were a significantly older and more experienced playing group, and were significantly better (p < 0.05) in measures of leg power, sprinting speed and the distance covered in the Yo Yo intermittent recovery test compared to the non-starters. Although there were trends for the superiority of the starters, the differences in lower and upper body strength, VJ and predicted VO(2)max were nonsignificant. The forwards generally produced the worst fitness scores of the playing positions with the midfielders having significantly lower skinfolds and the defenders possessing better hamstring strength and VJ compared to the forwards. It was concluded that some fitness qualities can differentiate between starters and non-starters, at least in one AFL club. Comparisons of playing positions and the development of fitness norms for AFL players require further research.
