An investigation into perceived autonomy support, motivation and competence in chronic pain patients in Ireland: A cross-sectional study.

Autonomy supportive healthcare settings are associated with enhanced behaviour change and self-management strategies in individuals living with chronic disease. The level of autonomy support provided by healthcare professionals to individuals living with chronic pain in Ireland is unknown. A cross-sectional study was completed on participants living with chronic pain (>3 months) in Ireland. Participants (n = 389) completed an anonymous survey constructed of patient reported outcome measures relating to autonomy support (HCCQ), motivation (TSRQ), competence in physical activity (PCS), pain interference (BPI) and psychological factors (PHQ-9, GAD-7). Results showed the median HCCQ (H = 39.287, p < .001), Autonomous Motivation (H = 13.568, p = 0.019) and PCS (H = 30.701, p < .001) scores were significantly different when patients received care from different healthcare professionals. There was a negative correlation between PCS and pain severity (r = -0.32, <0.01), pain interference (r = -0.44, p = <0.01), PHQ-9 (r = -0.50, p = <0.01) and GAD-7 (r = -0.34, p = <0.01). This study has identified that perceived healthcare support in Ireland varies according to the healthcare professional leading pain care. Furthermore, higher levels of self-determination were associated with decreased depression and anxiety in individuals with chronic pain. Given the limited number of multidisciplinary team clinics to provide pain management programs, an alternative cost-effective community led solution is required. The results of this study indicate that allied health professionals may be well placed to fill this void. Future research exploring the barriers to providing healthcare supportive settings is required.

Implementing hamstring injury prevention programmes remotely: a randomised proof of concept trial.

Objectives: This study aimed to (1) compare the effectiveness of a Nordic hamstring exercise (NHE) versus single-leg Romanian deadlift (SLRDL) exercise programme on a hamstring injury risk surrogate; (2) compare the muscle soreness experienced by both exercise programmes; and (3) assess compliance to remote injury prevention exercise protocols through video software. Methods: Twenty participants (10 women and 10 men: 21.45±1.6 years; 176±23 cm; 70±10 kg) were randomised into an NHE or SLRDL programme for 6 weeks. Single-leg hamstring bridge (SLHB), a hamstring injury surrogate, was the primary outcome for exercise efficacy. Muscle soreness and exercise adherence were also assessed. Significance was set at p<0.05. Results: Both exercises increased SLHB performance resulting in an overall effect (p=0.013) with no effect for group (p=0.470) and no interaction effect (p=0.709), indicating both groups improved but there was no difference in improvement between interventions. There was no difference in muscle soreness between groups (p=0.087). Finally, both groups had 100% adherence to the programme. Conclusions: Both the NHE and SLRDL are equally effective in increasing SLHB performance and demonstrate a similar level of muscle soreness. This suggests that SLRDL may be a viable option as a preventative exercise to mitigate the risk of hamstring injury. Finally, implementing injury prevention programmes remotely has the potential to enhance adherence.

Current Concussion Knowledge, Beliefs, Education, and Management Practices Among Irish Post-Primary PE Teachers.

Purpose: Physical education (PE) teachers play an important role in concussion recognition and management in schools both in an academic and activity based setting. This study aimed to identify Irish post-primary PE teachers' concussion knowledge, beliefs, education and management practices. Methods:  An anonymous online survey, adapted to the Irish context from the validated BAKPAC-TEACH, was completed by 128 PE teachers (female = 74/123; 60.2%; male = 49/123; 39.8%, 36.1 ± 10.9 years), representing 4% of registered PE teachers in Ireland. Results: PE teachers reported 3.5 ± 4.7 students suffer with a sports-related concussion in their classroom annually and 43.9% previously had a student sustain a concussion during their PE class. Most received concussion education (58.6%), largely provided by sporting bodies. They frequently identified dizziness (93.0%) and headaches (92.2%) as concussion symptoms, but less commonly emotional (more emotional = 36.5%, nervous or anxious = 33.6%, sadness = 28.9%) or sleep (35.2%) symptoms. All PE teachers knew that a concussion requires immediate removal from a game/practice. PE teachers demonstrated less perceived knowledge and confidence relating to academic adjustments and return to learn criteria. Just 31.3% reported their school facilitates academic adjustments. Conclusion: Tailored concussion education addressing knowledge gaps highlighted in this study should be developed. A concussion policy and an academic support team in each school should be established and widely publicised to enhance the support of concussed students in returning to school.

The Running Injury Continuum: A qualitative examination of recreational runners' description and management of injury.

INTRODUCTION: A critical step in understanding and preventing running-related injuries (RRIs) is appropriately defining RRIs. Current definitions of RRIs may not represent the full process of injury development, failing to capture lower levels of injury that many athletes continue to train through. Understanding runners' description and management of the injury development process may allow for a more appropriate examination of all levels of injury. This study aimed to examine recreational runners' description and management of the injury development process. METHODS: A qualitative focus group study was undertaken. Seven semi-structured focus groups with male (n = 13) and female (n = 18) recreational runners took place. Focus groups were audio and video recorded, and transcribed verbatim. Transcripts were reflexively thematically analysed. A critical friend approach was taken to data coding. Multiple methods of trustworthiness were executed. RESULTS: Runners describe injury on a nine-level continuum, ranging from injury-free to career-ending injury. There are lower and higher levels of injury. Each level of injury is described across four categories of descriptors; physical description, outcome (effect on running and daily life), psychological description, and management. CONCLUSION: The Running Injury Continuum is a tool that can be used for injury surveillance (for healthcare professionals and researchers) and for research investigating RRI risk factors. Healthcare professionals, researchers and coaches must ensure they monitor the development of all levels of RRIs, across all categories of descriptors. Runners need to be educated regarding appropriate self-management strategies for lower level injuries, with access to evidence-based information being a critical management tool.

Running towards injury? A prospective investigation of factors associated with running injuries.

BACKGROUND: Given the high incidence and heavy burden of running related injuries, large-scale, prospective multifactorial investigations examining potential risk factors are warranted. This study aimed to identify factors associated with running related injuries and to evaluate their potential in injury screening. STUDY DESIGN: Prospective cohort study. MATERIALS AND METHODS: Two hundred and seventy-four recreational runners were recruited. Clinical measures (strength, range of motion, foot position), injury and training history (via questionnaire), impact loading (via accelerometery) and running technique measures were collected at baseline. Runners were tracked for injury for one year via fortnightly check-ins. A binary logistic regression, (injury versus no injury), was performed for each variable univariably, and then adjusting for age, sex and mileage. A multivariable regression was also performed to evaluate the model's discriminative ability. RESULTS: Of the 225 runners included in the final analysis 52% experienced a running related injury. Injury history in the past year, less navicular drop, and measures of running technique (knee, hip, and pelvis kinematics) were associated with increased odds of injury (p < .05). The multivariable logistic regression model was statistically significant, χ2(11) = 56.45, p < .001, correctly classifying 74% of cases with a sensitivity and specificity of 72% and 76%, respectively. The area under the receiver operating characteristic curve was 0.79 (CI95% = 0.73-0.85), demonstrating acceptable discriminative ability. CONCLUSIONS: This study found a number of clinical and running technique factors to be associated with prospective running related injuries among recreational runners. With the exception of injury history, the factors identified as being significantly associated with injury may be modifiable and therefore, could form the basis of interventions. Range of motion, spatiotemporal parameters and strength measures were not associated with injury and thus their utilisation in injury prevention practices should be reconsidered.

Gaelic games players' awareness and use of, and attitudes towards injury prevention exercise programmes.

OBJECTIVE: The aim was to determine the awareness of and use of injury prevention exercise programmes (IPEPs) among adult Gaelic games players and to investigate Gaelic games players' attitudes to injury prevention and barriers and facilitators to successful IPEPs use. METHODS: A recruitment email was sent to all clubs and county boards throughout Ireland (whose email was available online) and the survey was advertised on social media platforms. Adult players completed an anonymous survey, including awareness, use, and attitudes towards injury prevention and injuries. Frequencies and descriptive statistics were conducted, a chi-squared test was used to assess any differences in awareness and use of IPEPs, a Mann-Whitney U test was used to examine differences between groups for attitudes to injury prevention (men vs women; elite vs non-elite). RESULTS: A third of players (32.4%) stated awareness of IPEPs. However, only 13.4% correctly identified one. A significantly greater number of men (35.7%) used IPEPs compared to women (26.5%) (p = 0.04). The Activate (65.5%) and GAA15 (32.5%) were most used. Players had a positive attitude towards injury prevention but agreed that injuries were an issue (68.2%) and stated that their coach didn't have enough knowledge how to use IPEPs was a large barrier (41.6%). CONCLUSION: Despite this positive attitude to injury prevention and believing injuries are an issue, adoption remains low. Organisations/clubs should educate players on the benefits of using IPEPs and support structures put in place to gain greater implementation, which is critical to mitigating the risk of injury.

Injury prevention in ladies Gaelic football referees: Understanding the barriers, facilitators, and preferences of referees.

OBJECTIVES: The injury prevalence in Gaelic games refereeing is high, however few are adopting injury prevention programmes. This study aims to identify the barriers and facilitators to injury prevention strategy success and determine Ladies Gaelic Football referees' preferences for injury prevention strategies and education. DESIGN: Semi-structured interviews were conducted with 11 Ladies Gaelic Football referees (10 men, 1 woman). Two were club level, two were provincial level and 7 were national level referees. Interviews were audio-recorded, transcribed verbatim, and reflexive thematic analysis was completed. This analysis involved examining the data repeatedly and gradually developing sub-themes, themes, and categories related to each core concept. RESULTS: The barriers to injury prevention success included negative attitudes, accessibility issues, lack of education, the state of refereeing and undesirable injury prevention strategy characteristics. Injury prevention promotion, suitable strategy characteristics and open communication were believed to facilitate success. Referees gave their preferences for injury prevention programmes, strategy logistics, and stakeholder roles along with their preferred topics, delivery, educators, characteristics, rollout, and timing for injury prevention education. CONCLUSIONS: Reducing referee injury is critical to the success of Ladies Gaelic Football and other community sports. Governing bodies must develop and support injury prevention programmes and education for referees. These should be designed according to referees' preferences and consider the barriers and facilitators referees have identified to maximise adoption.

Factors associated with concussion management behavior in Ladies Gaelic Football players.

BACKGROUND: Sport-related concussion (SRC) management may be poor in community sports such as Ladies Gaelic Football (LGF). This study examined factors associated with SRC management behavior in adult LGF players. METHODS: Participants (n = 657) answered an online survey on demographic factors, concussion knowledge, attitudes, and education, and SRC management behavior. Data from participants who reported sustaining an LGF-related SRC during the previous year (n = 115) were further analyzed. RESULTS: Being diagnosed with SRC was the main factor influencing subacute management behavior. Players with diagnosed SRCs had increased odds of following a graded return-to-play (RTP) programme (OR = 4.89), following a medically supervised graded RTP programme (OR = 10.16), and being medically cleared before full RTP (OR = 13.45) compared with those with suspected SRCs. Concussion history was associated with increased odds of informing a coach of a possible SRC (OR = 2.86). Demographic factors, previous use of Ladies Gaelic Football Association concussion education resources, and concussion knowledge and attitudes had minimal or no influence on management behaviors. CONCLUSION: Greater access to medical personnel at LGF training and matches is recommended. Due to limited medical resources in community sport, a clear referral pathway for players with SRC and comprehensive SRC education should be introduced to ensure players receive adequate medical care.

Aetiological Factors of Running-Related Injuries: A 12 Month Prospective "Running Injury Surveillance Centre" (RISC) Study.

BACKGROUND: Running-related injuries (RRIs) are a prevalent issue for runners, with several factors proposed to be causative. The majority of studies to date are limited by retrospective study design, small sample sizes and seem to focus on individual risk factors in isolation. This study aims to investigate the multifactorial contribution of risk factors to prospective RRIs. METHODS: Recreational runners (n = 258) participated in the study, where injury history and training practices, impact acceleration, and running kinematics were assessed at a baseline testing session. Prospective injuries were tracked for one year. Univariate and multivariate Cox regression was performed in the analysis. RESULTS: A total of 51% of runners sustained a prospective injury, with the calf most commonly affected. Univariate analysis found previous history of injury < 1 year ago, training for a marathon, frequent changing of shoes (every 0-3 months), and running technique (non-rearfoot strike pattern, less knee valgus, greater knee rotation) to be significantly associated with injury. The multivariate analysis revealed previous injury, training for a marathon, less knee valgus, and greater thorax drop to the contralateral side to be risk factors for injury. CONCLUSION: This study found several factors to be potentially causative of injury. With the omission of previous injury history, the risk factors (footwear, marathon training and running kinematics) identified in this study may be easily modifiable, and therefore could inform injury prevention strategies. This is the first study to find foot strike pattern and trunk kinematics to relate to prospective injury.

A qualitative examination of injury prevention strategy and education in Ladies Gaelic football: Understanding the preferences of players and coaches.

The high rates of injury in Ladies Gaelic football impact the wellbeing of players and are a major financial burden for the Ladies Gaelic Football Association. Effective injury prevention programmes have been developed for Gaelic games, but these are not currently widely adopted. The aim of this study was to qualitatively investigate adult Ladies Gaelic football players and coaches' preferences for injury prevention strategies and injury prevention education using a constructivist grounded-theory approach. Semi-structured interviews were conducted with 23 currently active Ladies Gaelic football coaches and adult players. The core strategy preferences discussed by participants were the properties of an injury prevention programme, the role of stakeholders, strategy logistics and the need for guidance and support. If the uptake and long-term adoption of an injury prevention programme is to be maximised, the preferences of the players and coaches who will ultimately utilise the programme must be understood and integrated into a wider implementation strategy developed around their needs. For education preferences, the core categories identified were the focus of education, who needs education, the format, educator, roll-out strategy, and time required. Future educational strategies must incorporate the preferences of stakeholders into their design if they are to be successful in spreading injury prevention knowledge and achieving change. To give injury prevention strategies, programmes, and education the best chances at successful adoption, it is crucial that the preferences of end-users are addressed and implemented.

Concussion in Ladies Gaelic Football: Self-reported History, Clinical Profiles, and Management Behavior.

OBJECTIVE: To describe the prevalence, characteristics, and management behavior of self-reported sport-related concussion (SRC) in Ladies Gaelic Football (LGF) players. DESIGN: Cross-sectional study. SETTING: Online survey distributed to LGF clubs throughout Ireland. PARTICIPANTS: Elite and nonelite adult LGF players (n = 657). INTERVENTIONS: Participants were recruited by convenience sampling and answered an online survey. Questions on demographic characteristics, SRC history, symptoms, injury characteristics, and management behavior after SRCs that occurred while playing LGF during the previous season were included. MAIN OUTCOME MEASURES: Overall concussion history, occurrence of an SRC during the previous LGF season, clinical profile scores, characteristics (eg mechanism and setting), and management behavior (eg following a graded RTP program) after SRCs that occurred during the previous season. RESULTS: Approximately one-fifth (17.5%) of participants sustained a suspected or diagnosed SRC during the previous season, which was higher among elite (26.1%) than nonelite (15.3%) players ( P < 0.01). The highest scoring clinical profiles were the ocular and migraine profiles. Only 3.5% of respondents adhered to all SRC management recommendations. Although players who reported a medically diagnosed versus a suspected SRC more often followed these guidelines, SRC management beyond the initial phase of injury remained inadequate. CONCLUSION: SRC is common in LGF; however, adherence to recommended management guidelines is poor, even among players who receive medical assistance. In particular, few LGF athletes receive clinical concussion care beyond the initial diagnosis and acute management phase. Further research is needed to examine the underlying reasons for poor SRC management in LGF, which will guide the development of future sport-specific interventions.

Perceptions of Concussion and Associated Anxiety in Irish Collegiate Athletes.

BACKGROUND: Concussion nondisclosure and poor management after a concussion are a concern in Irish collegiate sports. How athletes perceive concussions and appraise their own concussion may affect their decisions and behaviors after a suspected concussion. However, this has yet to be examined in an Irish context. This study aimed to (1) establish concussion perceptions and associated anxiety in Irish collegiate athletes; (2) examine how sex, concussion, and mood disorder history influenced their perceptions; and (3) investigate factors associated with higher anxiety perceptions. HYPOTHESIS: Irish collegiate athletes will display negative concussion perceptions and anxiety related to concussion, especially in female athletes and those without a concussion history. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: Irish collegiate athletes [n = 268 (141 women,127 men), mean age = 21.5 ± 2.2 years] from high-risk sports completed a survey including the Perceptions of Concussion Inventory for Athletes (PCI-A), demographics, diagnosed concussion history, self-reported mood disorder history, and a concussion knowledge assessment. Differences in concussion perceptions by sex, concussion history, mood disorder history were examined using Mann-Whitney U tests, and factors associated with anxiety-related concussion perceptions were identified using multivariate logistic regression. RESULTS: Over half (53.0%, n = 142) of participants reported concerns regarding concussion. The thoughts of sustaining a concussion made participants feel upset (63.4%, n = 170), fearful (47.7%, n = 128), and anxious (35.1%, n = 94). Women reported significantly higher anxiety (P < 0.01, r = 0.23), effects (P = 0.04, r = 0.12), and clarity (P = 0.01, r = 0.16) perception scores. Participants with a diagnosed concussion history displayed greater symptom variability perception scores (P = 0.04, r = 0.12), but lower anxiety (P = 0.03, r = 0.13) and treatment (P < 0.01, r = 0.19) beliefs on the PCI-A. No differences were observed for those with a history of a mood disorder (P > 0.05). A significant multivariate model was established (χ2 = 55.44, P < 0.01), with female sex [odds ratio (OR) = 1.53], concussion history (OR = 0.63), effects (OR = 1.31), and treatment (OR = 1.15) subscales associated with greater anxiety. CONCLUSION: Concerns about sustaining a concussion are prevalent in Irish collegiate athletes. Women displayed more negative perceptions and those with a concussion history displayed fewer perceived benefits of treatment. CLINICAL RELEVANCE: The findings support the need for concussion awareness campaigns to provide accurate concussion information to mitigate anxiety-related concussion perceptions and injury belief misconceptions.

Current Practices, Willingness and Perceived Ability to Implement an Injury Prevention Exercise Program Among Post-Primary Physical Education Teachers.

BACKGROUND: Musculoskeletal injuries are common in adolescents, and recently schools have been suggested as an opportune location for injury prevention strategies. This study aimed to identify the current practices and perceptions of post-primary PE teachers in Ireland on injury prevention exercise programs (IPEP), which are key to informing potential implementation strategies. METHODS: Post-primary PE teachers (n = 287) completed an online anonymous survey. Outcome measures included current IPEP practices in PE class, teachers' attitudes toward IPEPs, willingness to implement, and perceived ability to implement an IPEP in PE class. Descriptive statistics were calculated, and Mann-Whitney U tests were used to compare differences between groups. RESULTS: Results indicated that only 1 in 5 PE teachers currently used an IPEP in class. Of these, no teacher used an existing IPEP exactly as intended, while most teachers were willing to implement an IPEP (80.5%). Those who previously received formal IPEP education or were aware of an existing IPEP had significantly higher perceived ability to implement an IPEP in class (p < .001). CONCLUSIONS: This study demonstrates that despite a willingness among PE teachers to implement IPEPs in class, few currently do. Thus, post-primary PE class may be an under-utilized setting for adolescent injury prevention and warrants further investigation.

The effects of multi-directional, high intensity exercise on the vestibular/ocular motor screening (VOMS) assessment in recreational athletes.

OBJECTIVE: Identify the effects of multi-directional, high intensity exercise on VOMS symptom scores in male and female recreational, college-aged athletes. DESIGN: Cross-sectional study. SETTING: Athletic Therapy facility. PARTICIPANTS: A convenience sample of 29 (15 females, 14 males; 21.48 ± 1.40 years old) healthy recreational athletes. MAIN OUTCOME MEASURES: VOMS symptom scores pre, immediately post-, and 10 min post a multidirectional, high intensity intermittent exercise protocol (HIIP). Friedman tests and Wilcoxon Signed Rank tests identified significant differences at the time points. A Mann-Whitney U Test investigated the effect of sex. RESULTS: The majority of component and overall VOMS symptom scores increased post-HIIP (p < 0.001-0.007, effect sizes 0.39-0.50) and 10 min post-HIIP (p = 0.003-0.015, effect sizes 0.32-0.39). Near point convergence distance increased immediately post-HIIP (p < 0.001, effect size 0.52). Females had higher smooth pursuits (z = -2.340, p = 0.019, r = 0.31), vertical vestibular ocular reflex (z = -2.81, p = 0.04, r = 0.39) visual motion sensitivity (z = -2.312, p = 0.021 r = 0.30) and overall VOMS symptom scores (z = -2.84, p = 0.04, r = 0.27) 10 min post-HIIP. CONCLUSIONS: Multidirectional, high intensity exercise can induce concussive-like changes in VOMS symptom scores in healthy, recreational athletes, particularly in females. These results may assist in SRC assessment and management of athletes involved in multidirectional, high intensity sports.

Comparison of impact accelerations between injury-resistant and recently injured recreational runners.

INTRODUCTION/PURPOSE: Previous injury has consistently been shown to be one of the greatest risk factors for running-related injuries (RRIs). Runners returning to participation following injury may still demonstrate injury-related mechanics (e.g. repetitive high impact loading), potentially exposing them to further injuries. The aim of this study was to determine if the magnitude (Peakaccel) and rate of loading (Rateaccel) at the tibia and sacrum differ between runners who have never been injured, those who have acquired injury resistance (runners who have not been injured in the past 2 years) and those who have been recently injured (RRI sustained 3-12 months ago). METHODS: Runners completed an online survey capturing details of their RRI history over the previous 2 years. Never injured runners were matched by sex, quarterly annual mileage and typical training speed to runners who had acquired injury resistance and to runners who had been recently injured. Differences in Peakaccel and Rateaccel of the tibia and sacrum were assessed between the three groups during a treadmill run at a set speed, with consideration for sex. RESULTS: A total of 147 runners made up the three injury status groups (n: 49 per group). There was a significant main effect of injury status for Peakaccel and Rateaccel at the sacrum, with recently injured runners demonstrating significantly greater Rateaccel than never injured and acquired injury resistant runners. There was also a significant main effect for sex, with females demonstrating greater tibial Peakaccel, sacrum Peakaccel and Rateaccel than males. CONCLUSION: Rateaccel at the sacrum distinguishes recently injured runners from never injured runners and runners who may have acquired injury resistance, potentially highlighting poor impact acceleration attenuation in recently injured runners.

Post-injury fear-avoidance and confidence in readiness to return to sport in Irish collegiate athletes.

Fear avoidance and low confidence in their ability to return to sport can impede athletes' subsequent recovery and return to sport. This study aimed to identify fear avoidance and confidence in readiness to return to sport following injury in Irish collegiate athletes. Male (416) and female (256) athletes from 24 field-sport teams at one university were prospectively followed for one season. The Athlete Fear Avoidance Questionnaire (AFAQ) and pain on the Visual Analogue Scale was completed following a time-loss injury. Prior to return to sport, participants completed the AFAQ and the Injury Psychological Readiness to Return to Sport (I-PRRS). We recorded 179 injuries. Fear avoidance was evident post-injury (21.8 ± 6.7), and the mean total I-PRRS score was 48.4 ± 8.9. Those with severe injuries presented with higher fear avoidance and lower confidence. Higher pain was associated with greater fear avoidance following injury (r = 0.32, p < 0.0001), prior to return to sport (r = 0.38, p < 0.0001), and with lower confidence (r = -0.27, p < 0.0001).   Low confidence and fear avoidance was identified, particularly in those with a severe injury or high pain levels. Identifying, and providing psychosocial support to athletes experiencing, these issues is recommended.

Are impact accelerations during treadmill running representative of those produced overground?

BACKGROUND: Although many runners train overground, measuring impact accelerations on a treadmill may be advantageous for researchers and clinicians. Previous investigations of peak and rate of acceleration (peakaccel, rateaccel) during treadmill running compared to overground running have not examined both the relative consistency and absolute agreement of these measures, or the effect of treadmill stiffness. RESEARCH QUESTION: (1) Are peakaccel and rateaccel produced during running on a stiff and less stiff treadmill 'representative' of those produced during overground running? (2) Are peakaccel and rateaccel measured on treadmills of different stiffness 'representative' of each other? METHODS: Eighteen participants ran at a self-selected pace on three surfaces: Treadmill 1 (reduced stiffness), Treadmill 2 (increased stiffness) and overground on asphalt, whilst peakaccel and rateaccel were recorded at the shank and lower back. Relative consistency (ICC (3,1)), absolute agreement (Bland-Altman analysis) and systematic differences (ANOVA/Friedman's Tests) were assessed. RESULTS: ICCs revealed moderate to excellent relative consistency in peakaccel and rateaccel between surfaces, with higher consistency for measures at the lower back. Absolute agreement was low, with the Bland Altman limits of agreement exceeding the clinical acceptable range for all comparisons. For systematic differences in means, peakaccel and rateaccel at the shank were significantly higher overground than on either treadmill; with no difference evident at the lower back. No differences were found for surface with respect to shank or lower back peakaccel and rateaccel between treadmills. SIGNIFICANCE: Moderate to excellent relative consistency of peakaccel and rateaccel between the surfaces suggests that using different surfaces in research involving rank ordering of participants by acceleration magnitude may be acceptable (e.g. prospective studies examining if impact accelerations are related to injury). However, low absolute agreement indicates that data collected on treadmills of different stiffness and overground should not be used interchangeably (e.g. running-retraining studies).

A qualitative examination of the factors affecting the adoption of injury focused wearable technologies in recreational runners.

PURPOSE: Understanding the perceived efficacy and ease of use of technologies will influence initial adoption and sustained utilization. The objectives of this study were to determine the metrics deemed important by runners for monitoring running-related injury (RRI) risk, and identify the facilitators and barriers to their use of injury focused wearable technologies. METHODS: A qualitative focus group study was undertaken. Nine semi-structured focus groups with male (n = 13) and female (n = 14) recreational runners took place. Focus groups were audio and video recorded, and transcribed verbatim. Transcripts were thematically analysed. A critical friend approach was taken to data coding, and multiple methods of trustworthiness were executed. RESULTS: Excessive loading and inadequate recovery were deemed the most important risk factors to monitor for RRI risk. Other important factors included training activities, injury status and history, and running technique. The location and method of attachment of a wearable device, the design of a smartphone application, and receiving useful injury-related information will affect recreational runners' adoption of injury focused technologies. CONCLUSIONS: Overtraining, training-related and individual-related risk factors are essential metrics that need to be monitored for RRI risk. RRI apps should include the metrics deemed important by runners, once there is supporting evidence-based research. The difficulty and/or ease of use of a device, and receiving useful feedback will influence the adoption of injury focused running technologies. There is a clear willingness from recreational runners to adopt injury focused wearable technologies whilst running.

Relative and absolute reliability of shank and sacral running impact accelerations over a short- and long-term time frame.

Whilst running is hugely popular, running-related injuries (RRIs) are prevalent. High impact loading has been proposed to contribute to RRIs, with accelerometers becoming increasingly popular in estimating segmental loading for injury detection and biofeedback training. However, there is a lack of research examining the reliability of measures of impact acceleration across short- and long-term time periods, both prior to and following exerted running. The aim of this study was to assess the absolute and relative reliability of shank and sacral impact accelerations over a short- and long-term time period. Peak (Peakaccel) and rate (Rateaccel) of impact acceleration at the shank and sacrum were assessed in 18 recreational runners over short- and long-term time frames, across fixed and self-selected speeds. The relative and absolute reliabilities were investigated for pre- and post-exerted states of running. There was high-to-excellent relative reliability, and predominantly moderate absolute reliability for shank and sacrum Peakaccel and Rateaccel in the short- and long-term time frames between pre- and post-exerted states. High to excellent relative reliability of Peakaccel and Rateaccel at the shank and sacrum are appropriate and acceptable measures across short- and long-term time frames. These findings were consistent with different levels of speed and exertion. The minimal detectable change % was large for both sensors and associated measurements, indicating that their use may be limited to intervention studies that elicit large change (>30%) in these measures.

Does stammering act as a barrier to exercise and sport in Irish adults who stammer?

PURPOSE: Exercise and sport participation lead to many physical and psychosocial benefits. However, barriers to exercise and sporting participation exist. This study aims to examine if stammering acts as a barrier to exercise and sporting participation in adults. METHODS: One hundred and six adults who stammer (male n = 74, female n = 32; 33.83 ± 14.5 years) completed an anonymous questionnaire which evaluated their stammering history, exercise and sporting participation, views on why they exercise, whether stammering prevented or negatively influenced their participation in exercise or sport. Descriptive statistics were then calculated. RESULTS: The majority (90.6 %) of participants take part in some form of exercise/sport. However, their stammer prevented them from taking part in a specific exercise/sport at least once (49.1 %), due to being too nervous to introduce themselves, nervous or fear of stammering or being judged. Their stammer also negatively impacted their involvement when participating at least once (42.4 %), with not feeling part of the team and fear of speaking reported. Self-disclosure of their stammer and improving awareness of stammering were identified as common facilitators for taking part in exercise/sport. CONCLUSION: Stammering was not found to impact general participation in exercise and sport but was identified as a barrier to partaking in specific exercise and sport and their enjoyment thereof. Encouraging those who stammer to inform those involved in sport and exercise (e.g. fellow players, coaches) about their stammer and improving stammer awareness across the general and sporting population may encourage further participation in exercise and sport in those who stammer.
