Training patterns and negative health outcomes in triathlon : longitudinal observations across a full competitive season

AIM: Despite heavy training requirements, triathlon is a sport that is rapidly increasing in popularity. Yet, there is limited research detailing the relationship between training, the incidence of injuries and illness, psychological stress, overtraining and athlete burnout amongst triathletes. Six hypotheses relating inter-individual differences to training factors were generated to evaluate change in self-reported measures of these negative health outcomes over a training year.

METHODS: Thirty, well-trained, triathletes (males n=20: age=27.1±9.1 years and females n=10: age=27.4±6.6 years) from a local triathlon club participated in this study. The study commenced during pre-season training, and involved weekly monitoring of each athlete until the end of the competitive season 45 weeks later. Linear Mixed Modelling was used for the analysis.

RESULTS: Signs and symptoms of injury and illness (SAS) were significantly associated with increases in training factors (P≤0.05); however, greatest impact on SAS was produced by psychological stressors (P≤0.001). Common symptoms of overtraining were significantly affected by increases in exposure to both training and psychological stressors (P≤0.05). Mood disturbance was not significantly affected by training factors (P>0.05) but rather increases in psychological stressors (P≤0.001). Finally, each of the three athlete burnout subscales were significantly affected by both psychological (P≤0.001) stressors as well as varying combinations of training factors (P≤0.05).

CONCLUSIONS: Exposure to stressors (either training or psychological) had significant effects on all negative health outcomes assessed.

User preference of cyber security awareness delivery methods

Operating systems and programmes are more protected these days and attackers have shifted their attention to human elements to break into the organisation's information systems. As the number and frequency of cyber-attacks designed to take advantage of unsuspecting personnel are increasing, the significance of the human factor in information security management cannot be understated. In order to counter cyber-attacks designed to exploit human factors in information security chain, information security awareness with an objective to reduce information security risks that occur due to human related vulnerabilities is paramount. This paper discusses and evaluates the effects of various information security awareness delivery methods used in improving end-users’ information security awareness and behaviour. There are a wide range of information security awareness delivery methods such as web-based training materials, contextual training and embedded training. In spite of efforts to increase information security awareness, research is scant regarding effective information security awareness delivery methods. To this end, this study focuses on determining the security awareness delivery method that is most successful in providing information security awareness and which delivery method is preferred by users. We conducted information security awareness using text-based, game-based and video-based delivery methods with the aim of determining user preferences. Our study suggests that a combined delivery methods are better than individual security awareness delivery method.

Training improves interobserver reliability for the diagnosis of scaphoid fracture displacement

Background The diagnosis of displacement in scaphoid fractures is notorious for poor interobserver reliability.

Questions/purposes We tested whether training can improve interobserver reliability and sensitivity, specificity, and accuracy for the diagnosis of scaphoid fracture displacement on radiographs and CT scans.

Methods Sixty-four orthopaedic surgeons rated a set of radiographs and CT scans of 10 displaced and 10 nondisplaced scaphoid fractures for the presence of displacement, using a web-based rating application. Before rating, observers were randomized to a training group (34 observers) and a nontraining group (30 observers). The training group received an online training module before the rating session, and the nontraining group did not. Interobserver reliability for training and nontraining was assessed by Siegel’s multirater kappa and the Z-test was used to test for significance.

Results There was a small, but significant difference in the interobserver reliability for displacement ratings in favor of the training group compared with the nontraining group. Ratings of radiographs and CT scans combined resulted in moderate agreement for both groups. The average sensitivity, specificity, and accuracy of diagnosing displacement of scaphoid fractures were, respectively, 83%, 85%, and 84% for the nontraining group and 87%, 86%, and 87% for the training group. Assuming a 5% prevalence of fracture displacement, the positive predictive value was 0.23 in the nontraining group and 0.25 in the training group. The negative predictive value was 0.99 in both groups.

Conclusions Our results suggest training can improve interobserver reliability and sensitivity, specificity and accuracy for the diagnosis of scaphoid fracture displacement, but the improvements are slight. These findings are encouraging for future research regarding interobserver variation and how to reduce it further.

Collaborative care skills training workshops : helping carers cope with eating disorders from the UK to Australia

Purpose

The Collaborative Care Skills Training workshops, developed by Treasure and associates aim to improve the well-being, coping strategies and problem-solving skills of carers of someone with an eating disorder. Evidence has demonstrated the effectiveness of the workshops in the UK where it was developed. The aim of this pilot study was to examine whether conducting the workshops in different contexts by facilitators trained in its delivery could lead to similar impact.
Methods

The workshops were conducted with 15 carers in VIC, Australia and delivered by experienced health professionals trained in its content and delivery. A non-experimental research design with repeated measures was implemented. Quantitative data were collected at pre-and post-intervention and 8 weeks after completion of the workshops.
Results

Participation led to significant reductions in carers’ reported expressed emotion, dysfunctional coping, distress, burden and accommodation and enabling of the eating disorder behaviour, which were maintained at the 8-week follow-up.
Conclusion

Results suggest the workshops are effective in reducing carer distress and burden as well as modifying unhelpful emotional interactional styles when caring for family members with an eating disorder. The content of the workshops and its delivery, once experienced facilitators have received training, are transferable to other contexts.

Evaluation of four supervised learning methods for benthic habitat mapping using backscatter from multi-beam sonar

An understanding of the distribution and extent of marine habitats is essential for the implementation of ecosystem-based management strategies. Historically this had been difficult in marine environments until the advancement of acoustic sensors. This study demonstrates the applicability of supervised learning techniques for benthic habitat characterization using angular backscatter response data. With the advancement of multibeam echo-sounder (MBES) technology, full coverage datasets of physical structure over vast regions of the seafloor are now achievable. Supervised learning methods typically applied to terrestrial remote sensing provide a cost-effective approach for habitat characterization in marine systems. However the comparison of the relative performance of different classifiers using acoustic data is limited. Characterization of acoustic backscatter data from MBES using four different supervised learning methods to generate benthic habitat maps is presented. Maximum Likelihood Classifier (MLC), Quick, Unbiased, Efficient Statistical Tree (QUEST), Random Forest (RF) and Support Vector Machine (SVM) were evaluated to classify angular backscatter response into habitat classes using training data acquired from underwater video observations. Results for biota classifications indicated that SVM and RF produced the highest accuracies, followed by QUEST and MLC, respectively. The most important backscatter data were from the moderate incidence angles between 30° and 50°. This study presents initial results for understanding how acoustic backscatter from MBES can be optimized for the characterization of marine benthic biological habitats. © 2012 by the authors.

Evaluation of an alcohol intervention training program for nurses in rural Australia

Aim: This paper reports on the development, implementation and evaluation of the Alcohol Intervention Training Program (AITP) designed to enhance nurses’ capacity to work with farming men and women who misuse alcohol.

Background: In rural and regional areas where alcohol-related behaviours and problems are relatively elevated, nurses may be the key health professionals dealing with individuals who misuse alcohol. However, they are often ill-equipped to do this, have low confidence in their ability to do so, and perceive numerous barriers. Training is required for these nurses.

Methods: We developed the AITP to enhance nurses’ capacity to work with people with alcohol-related problems. The data were collected during 2010. An intervention group of 15 rural nurses completed the AITP. Nurses’ perceived barriers, attitudes, and perceived performance in working with clients with alcohol problems, and the frequency of engaging with this client group were evaluated. Scores on these measures were compared to those of a control group of 17 nurses’ pre-treatment, post-treatment and at 3-month follow-up.

Results: Participation in the AITP resulted in initial improvements in attitudes to working with alcohol problems, but no change in perceived barriers to doing so. The level of engagement with clients having alcohol-related problems increased, as did perceptions of work performance.

Conclusion: The AITP enhances the ability of rural nurses to address the alcohol and associated health issues of clients in rural and regional areas. However, the program needs refinement and further evaluation.

Screening and intervention for mental health problems in alcohol and other drug settings: Can training change practitioner behaviour?

Aims: The comorbidity of substance use and mental health problems poses a significant challenge for alcohol and other drug (AOD) treatment services. In many cases, AOD practitioners do not have experience or training in identifying or managing mental health conditions. Methods: This project examined the implementation of screening and intervention practices for mental health disorders among AOD clients. Training and supervision was provided to 20 AOD practitioners across five sites in four agencies with a focus on enhancing skills in detection of, and intervention for, mental health conditions among their clients. A package developed for this purpose, known as PsyCheck, was used. A random file audit was undertaken to examine changes in detection of mental health conditions. Findings: There were significant improvements in detection after training and supervision, with detection rates almost doubling in this time. Conclusions: Training and supervision using the PsyCheck package appears to have the potential to improve mental health detection and intervention in AOD services. This study shows promise for the implementation of mental health intervention in AOD services.

Training skills of divided attention among older adults

The current study examined whether video game training would help improve divided attention skills among older adults. Twenty-nine (4 males, 25 females) participants aged 50 to 84 years (M = 70) were tested for their skills of divided attention using a memory and reaction time task. Participants were randomly allocated to the experimental group and control group and only those in the experimental group trained with the computer game, Pac-Man Adventures in Time for three hours. Results show that three hours of training are not sufficient to enhance skills of divided attention amongst older adults as the differences in these skills were not significantly different between control and experimental groups. These findings suggest that greater amounts or other methods of training may be required to enhance older adults’ ability to perform dual tasks.

Anodal tDCS applied during strength training enhances motor cortical plasticity

Purpose:
The objective of this study was to assess the effect of anodal transcranial direct current stimulation (a-tDCS) on voluntary dynamic strength and cortical plasticity when applied during a 3-wk strength training program for the wrist extensors.

Methods:
Thirty right-handed participants were randomly allocated to the tDCS, sham, or control group. The tDCS and sham group underwent 3 wk of heavy-load strength training of the right wrist extensors, with 20 min of a-tDCS (2 mA) or sham tDCS applied during training (double blinded). Outcome measures included voluntary dynamic wrist extension strength, muscle thickness, corticospinal excitability, short-interval intracortical inhibition (SICI), and silent period duration.

Results:
Maximal voluntary strength increased in both the tDCS and sham groups (14.89% and 11.17%, respectively, both P < 0.001). There was no difference in strength gain between the two groups (P = 0.229) and no change in muscle thickness (P = 0.15). The tDCS group demonstrated an increase in motor-evoked potential amplitude at 15%, 20%, and 25% above active motor threshold, which was accompanied by a decrease in SICI during 50% maximal voluntary isometric contraction and 20% maximal voluntary isometric contraction (all P < 0.05). Silent period decreased for both the tDCS and sham groups (P < 0.001).

Conclusion:
The application of a-tDCS in combination with strength training of the wrist extensors in a healthy population did not provide additional benefit for voluntary dynamic strength gains when compared with standard strength training. However, strength training with a-tDCS appears to differentially modulate cortical plasticity via increases in corticospinal excitability and decreases in SICI, which did not occur following strength training alone

A parallel-group, randomised controlled trial of a multimedia, self-directed, coping skills training intervention for patients with cancer and their partners: design and rationale

Introduction:

O where are you going? O do you imagine? Reproduction and response : a reflexive sociology of scholarship of teaching and learning in practical legal training

My doctoral research studies Australian PLT practitioners’ engagement with scholarship of teaching and learning. I argue that many PLT practitioners are motivated to engage with scholarship of teaching and learning in their work. There are, however, individual and extra-individual impediments.
PLT practitioners are lawyers that teach in institutional practical legal training (“PLT”). Satisfactory completion of mandatory PLT is an eligibility requirement for admission to the Australian legal profession. The PLT requirement is additional to academic legal qualifications. PLT is undertaken at a post-graduate level with, or after, the academic law degree.
My study investigates PLT practitioners’ motivations and capabilities to engage with scholarship of teaching and learning (“SoTL”). I study organisational symbolic support for SoTL in PLT, and organisational allocation of resources to SoTL in PLT.
The study involves individual and extra-individual domains of PLT practitioners’ work. It considers how social structures (e.g. “the juridical”) are inscribed into individuals’ practices (“teaching”) and, conversely, whether practices influence social structures.
My research adopts qualitative methodologies. These involve inter-disciplinary exchanges between law, legal education, practice research, sociology of law, cultural theory, and theory and practice of teaching and learning. My theoretical framework draws on Pierre Bourdieu’s “reflexive sociology”, and Michel de Certeau’s “heterological science”.
I sourced data from documents, and semi-structured interviews with 36 Australian PLT practitioners. Documentary sources include statutory instruments, speeches, reports, practice directions, histories, and scholarly publications.
To analyse the data I adopted Kelle’s characterisation of “theoretical sensitivity”, drawing on “explicit” and “emergent” analysis strategies derived from “grounded theory”. The explicit strategies were based on my theoretical framework. The emergent strategy involved sensitivity to non-explicit concepts and theories that emerged from the data. Computer-aided qualitative data analysis software expedited these methods.
My findings to date question dominant legal structures’ readiness for change, the implications of this for teaching and learning in PLT, and in particular for PLT practitioners’ engagement with SoTL in PLT.
The espoused rationale for mandatory PLT (in statutes) is improvement for the protection of clients, the administration of justice, and to assure quality legal services. The tacit rationale is improved quality of legal education, and experiences, for lawyers-to-be. My thesis argues dominant structures in legal education impede the espoused and tacit objectives, and impede PLT practitioners’ engagement with scholarship of teaching and learning.

Pedagogy, police training, D/discourses – “truth” and situated identities and meanings

Qualitative and quantitative methods were used in this research to distinguish the prevailing D/discourses (words, tools, beliefs, thinking styles) in police training and to analyse the ‘discourse-practice’ (Cherryholmes 1988, p.1) framework of policing in a training environment. The manifestations, functions and consequences of the D/discourses raise concerns about the efficacy of training (its doctrinal intent and value versus its educative intent and value) and its implications for individuals’ identity, subjectivity, agency, learning, and “membership” within the policing community. The literature revealed that police training acts as a formally sanctioned vehicle for police culture, subcultures, and D/discourses. This is complicated by (a) the predominance of pedagogical training practices that support a trainer-centred approach and standardised lecture format for training, (b) police training focusing predominantly on law enforcement at the cost of higher-order conceptual skills, and (c) Australian and international studies of police management education which reveal a subculture resistant to theoretical analysis and critical reflection, and a set of unconscious and unchallengeable assumptions regarding police work, conduct, and leadership. A backdrop to this research and findings is the agenda of Australian and New Zealand police services for police to become a profession.

Development and implementation of a novel measure for quantifying training loads in rowing : the T2minute method

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

Assessing effectiveness of aggression replacement training at a technical college in Thailand

Youth violence is a significant public health issue in Thailand where most people who are injured are vocational college students. There is a need to identify methods whereby such violence can be prevented. We trialed a group program in a technical college in Thailand with 23 students who received a modified version of aggression replacement training. We then compared their results with those of 24 students who did not receive any intervention or preintervention at 1 and 3 month followups. Although we found little evidence supporting the effectiveness of the intervention, participants in the intervention group suggested in the followup in-depth interviews that they felt more able to avoid or ignore provocation, and that they thought more about the consequences of aggressive behavior than they did prior to the intervention.
