Meta-analysis has become commonplace within sport and exercise science for synthesising and summarising empirical studies. However, most research in the field focuses upon mean effects, particularly the effects of interventions to improve outcomes such as fitness or performance. It is thought that individual responses to interventions vary considerably. Hence, interest has increased in exploring precision or personalised exercise approaches. Not only is the mean often affected by interventions, but variation may also be impacted. Exploration of variation in studies such as randomised controlled trials (RCTs) can yield insight into interindividual heterogeneity in response to interventions and help determine generalisability of effects. Yet, larger samples sizes than those used for typical mean effects are required when probing variation. Thus, in a field with small samples such as sport and exercise science, exploration of variation through a meta-analytic framework is appealing. Despite the value of embracing and exploring variation alongside mean effects in sport and exercise science, it is rarely applied to research synthesis through meta-analysis. We introduce and evaluate different effect size calculations along with models for meta-analysis of variation using relatable examples from resistance training RCTs.

This position paper examines decision-making in sport psychology practitioners from a dual processing perspective. Based on the work of Kahneman and Tversky, we draw upon cognitive and social psychology research to explore key decision-making vulnerabilities in the context of the sport psychology practitioner. We examine the influence of classic heuristics and biases, exploring issues such as: an exclusive focus on the inside view; tunnel vision; focusing on disposition as opposed to situation; the sport environment as a complex adaptive system; formulas for success; phase transitions; and conflating skill and luck. When considering how to combat such decision-making vulnerabilities, we explore a ‘counterintuitive’ approach developed by Mauboussin to mitigating these, and explain how sport psychology practitioners can apply such strategies. We suggest counterweight strategies, including: raising awareness of how biases and heuristics may be affecting our decision-making; diversifying our perspectives; proactively seeking critical feedback from diverse sources; creating useful checklists; and performing ‘pre-mortems’. Likewise, we explore strategies for future research on decision-making in sport psychology practitioners. Lay summary: This position paper draws on research from social, cognitive and sport psychology to explore key decision-making vulnerabilities in the context of the sport psychology practitioner. We provide evidence-based suggestions to mitigate these vulnerabilities, and strategies for how practitioners can apply these ideas in their practice.Implications for Practice A dual-processing approach has considerable potential for highlighting, and mitigating against, key decision-making vulnerabilities in sport psychology practitioners The systematic use of evidence-based strategies could greatly enhance decision-making quality in practitioners.

Background: The self-expanding, intra-annular Navitor (Abbott Structural Heart) valve includes an outer cuff to reduce paravalvular leak (PVL) and large stent cells for future coronary access. Objectives: The purpose of the PORTICO NG (Evaluation of the Portico NG [Next Generation] Transcatheter Aortic Valve in High and Extreme Risk Patients With Symptomatic Severe Aortic Stenosis) study is to evaluate the safety and effectiveness of the Navitor valve in patients with symptomatic, severe aortic stenosis who are at high or extreme surgical risk. Methods: PORTICO NG is a prospective, multicenter, global study with follow-up at 30 days, 1 year, and annually through 5 years. The primary endpoints are all-cause mortality and moderate or greater PVL at 30 days. Valve Academic Research Consortium-2 events and valve performance are assessed by an independent clinical events committee and echocardiographic core laboratory. Results: A total of 260 subjects were treated at 26 clinical sites across Europe, Australia, and the United States between September 2019 and August 2022. The mean age was 83.4 ± 5.4 years, 57.3% were female, and the average Society of Thoracic Surgeons score was 3.9% ± 2.1%. At 30 days, the rate of all-cause mortality was 1.9%, and no subjects had moderate or greater PVL. The rate of disabling stroke was 1.9%, life-threatening bleeding was 3.8%, stage 3 acute kidney injury was 0.8%, major vascular complications were 4.2%, and new permanent pacemaker implantation was 19.0%. Hemodynamic performance included a mean gradient of 7.4 ± 3.5 mm Hg and an effective orifice area of 2.00 ± 0.47 cm2. Conclusions: The Navitor valve is safe and effective for the treatment of subjects with severe aortic stenosis who are at high or greater risk for surgery, which is supported by low rates of adverse events and PVL.

Research has shown that motor imagery (MI) interventions, involving the systematic and repeated imagination of visual and kinaesthetic components of movements, can enhance performance in sport. Twenty years ago, Holmes and Collins (2001) published the PETTLEP model as a framework to improve the delivery and outcome of MI interventions. The model outlined seven principles to be considered when designing effective imagery interventions: Physical, Environment, Task, Timing, Learning, Emotion, Perspective (i.e., PETTLEP). The incorporation of these principles within MI interventions was assumed to facilitate performance through the optimisation of a functional equivalence between the neurophysiological substrates of motor preparation and execution, and that of MI. Since its conception, this model has become a standard for many in the delivery of imagery interventions in sport and has been corroborated through research and practice. This 20-year review first covers the reach and impact of this influential model and the more recent empirical investigations related to PETTLEP. We then outline how PETTLEP-based imagery may be integrated with action observation to support an increasingly popular approach to the delivery of imagery interventions in sport. Research indicates that combining these two simulation states can enhance sport performance whilst also providing the sport psychologist more control over the imagery experience than is possible through traditional imagery interventions. This article discusses the application of PETTLEP within a combined action observation and imagery framework and provides guidance for sport psychologists for the creation of new PETTLEP-informed interventions.

Background: Since many people choose to perform resistance training unsupervised, and a lack of supervision within strength training is reported to result in inadequate workout quality, we aimed to compare outcomes for resistance training with and without supervision. Methods: A systematic review and meta-analysis were performed for performance/functional outcomes and/or body composition measurements. Results: 12 studies were included in the review; 301 and 276 participants were in supervised and unsupervised groups, respectively. The main model for all performance/function effects revealed a small, standardised point estimate favouring SUP (0.28 [95%CI = 0.02 to 0.55]). For sub-grouped outcome types, there was very poor precision of robust estimates for speed, power, function, and endurance. However, for strength there was a moderate effect favouring SUP (0.40 [95%CI = 0.06 to 0.74]). The main model for all body composition effects revealed a trivial standardised point estimate favouring SUP (0.07 [95%CI = -0.01 to 0.15]). Conclusions: Supervised resistance training, compared to unsupervised training, might produce a small effect on increases in performance/function, most likely in strength, but has little impact on body composition outcomes.

Purpose Investigate the impact of 12-weeks’ moderate-intensity resistance training on psychological parameters in ambulatory adults with Facioscapulohumeral, Becker, and Limb–girdle muscular dystrophy. Methods Seventeen adults with Facioscapulohumeral (n = 6), Limb–girdle (n = 6; types 2A, 2B, 2L, and 2I), or Becker (n = 5) muscular dystrophy took part. Participants were tested at baseline (PRE), after a 12-week control period (PRE2), and after a 12-week supervised resistance training programme (POST). Training included multi-joint and single-joint resistance exercises. Outcomes from self-report questionnaires were health-related quality of life, depressive symptoms, trait anxiety, self-esteem, and physical self-worth. Results No difference in outcome measures, except depressive symptoms, was found in the control period (PRE to PRE2). Symptoms of depression were reduced by 9% from PRE to PRE2 (p < 0.05) and by a further 19% from PRE2 to POST (p < 0.05). Other changes from PRE2 to POST were that trait anxiety reduced by 10%, self-esteem increased by 10%, physical self-worth increased by 20%, and quality of life improved in 8 domains (p < 0.05). Conclusion These findings demonstrate the positive impact of moderate-intensity resistance training on psychological health and quality of life in adults with Facioscapulohumeral, Becker, and Limb–girdle muscular dystrophies. Implications for rehabilitation Resistance training can have a positive impact on psychological health and quality of life in adults with Facioscapulohumeral, Becker, and Limb–girdle muscular dystrophy. Healthcare professionals should consider including moderate-intensity resistance training within the management and treatment programmes of adults with Facioscapulohumeral, Becker, and Limb–girdle muscular dystrophy.

Purpose: It has been suggested that the media influence beliefs regarding ideal body appearance and drive for muscularity whilst also offering recommendations for achieving this; most commonly heavy load free weight resistance training (RT). However, evidence for media effects are inconsistent in the literature. This study investigated this "lift big-get big" culture and effects of imagery on males' beliefs regarding RT. Method: An online survey was conducted with male participants (N = 110) randomized to different images (hyper-muscular/lean/control) and RT information ("lift big-get big"/"evidence based RT"/control). Results: Descriptive data suggested belief in necessity of heavy loads and free weights was pervasive. There was a small significant effect of condition for multivariate analysis of beliefs regarding RT. Univariate analyses showed significant effects of condition regarding the importance of free weights and heavy loads for strength, and free weights for hypertrophy. Small to moderate effects were found comparing "evidence-based RT" with a hyper-muscular physique to "lift big-get big" conditions with both hyper-muscular and lean physiques, the latter more likely to agree free weights and heavy loads are necessary for strength. A small effect was found comparing "lift big-get big" conditions with both hyper-muscular and lean physiques and the control condition, the former more likely to agree free weights are necessary for hypertrophy. Conclusions: Although hyper-muscular bodies alone did not influence RT beliefs, new information, i.e., "evidence-based RT" combined with a hyper-muscular physique had a small effect. The "lift big-get big" culture is perhaps pervasive enough that most conditions merely reinforced existing beliefs.

Introduction Understanding the impact of lockdown upon resistance training (RT), and how people adapted their RT behaviours, has implications for strategies to maintain engagement in similar positive health behaviours. Further, doing so will provide a baseline for investigation of the long-term effects of these public health measures upon behaviours and perceptions, and facilitate future follow-up study. Objectives To determine how the onset of coronavirus (COVID-19), and associated ‘lockdown’, affected RT behaviours, in addition to motivation, perceived effectiveness, enjoyment, and intent to continue, in those who regularly performed RT prior to the pandemic. Methods We conducted an observational, cross-sectional study using online surveys in multiple languages (English, Danish, French, German, Italian, Portuguese, Slovakian, Swedish, and Japanese) distributed across social media platforms and through authors’ professional and personal networks. Adults (n = 5389; median age = 31 years [interquartile range (IQR) = 25, 38]), previously engaged in RT prior to lockdown (median prior RT experience = 7 years [IQR = 4, 12]) participated. Outcomes were self-reported RT behaviours including: continuation of RT during lockdown, location of RT, purchase of specific equipment for RT, method of training, full-body or split routine, types of training, repetition ranges, exercise number, set volumes (per exercise and muscle group), weekly frequency of training, perception of effort, whether training was planned/recorded, time of day, and training goals. Secondary outcomes included motivation, perceived effectiveness, enjoyment, and intent to continue RT. Results A majority of individuals (82.8%) maintained participation in RT during-lockdown. Marginal probabilities from generalised linear models and generalised estimating equations for RT behaviours were largely similar from pre- to during-lockdown. There was reduced probability of training in privately owned gyms (~ 59% to ~ 7%

The impacts of potentially treatable psychological parameters on quality of life are relatively unreported in adults with Facioscapulohumeral, Becker and Limb-girdle muscular dystrophy. The purpose of this study was to compare quality of life, psychological parameters, and physical function between adults with muscular dystrophy and controls, and to examine relationships among these parameters in muscular dystrophy. Twenty-one adults with muscular dystrophy (n = 7 Becker, n = 8 Facioscapulohumeral, n = 6 Limb-girdle) and ten age-matched controls participated. Outcome measures were health-related quality of life, depressive symptoms, trait anxiety, self-esteem, physical self-worth and six-minute walk distance. Quality of life scores were lower in the muscular dystrophy groups than the control (p < .05). Depressive symptoms had the greatest association with quality of life in the Mental Health domain (r= -0.89, p < .001). Depressive symptoms also had the most associations with quality of life (7 of 10 domains), followed by trait anxiety (6 of 10 domains), physical self-worth (5 of 10 domains), self-esteem (4 of 10 domains) and six-minute walk distance (3 of 10 domains). Psychological parameters and, to a lesser extent, physical function impact quality of life in muscular dystrophy. This study provides a rationale to include psychological assessment and treatment within muscular dystrophy healthcare.

During its commissioning phase, the Copernicus Sentinel-3B satellite has been placed in a tandem formation with Sentinel-3A for a period of 6 months. This configuration allowed a direct comparison of measurements obtained by the two satellites. The purpose of this paper was to present the range of analyses that can be performed from this dataset, highlighting methodology aspects and the main outcomes for each instrument. We examined, in turn, the benefit of the tandem in understanding instrument operational modes differences, in assessing inter-satellite differences, and in validating measurement uncertainties. The results highlighted the very good consistency of the Sentinel-3A and B instruments, ensuring the complete inter-operability of the constellation. Tandem comparisons also pave the way for further improvements through harmonization of the sensors (OLCI), correction of internal stray-light sources (SLSTR), or high-frequency processing of SRAL SARM data. This paper provided a comprehensive overview of the main results obtained, as well as insights into some of the results. Finally, we drew the main lessons learned from the Sentinel-3 tandem phase and provided recommendations for future missions.

Islet transplantation has become a viable clinical treatment, but is still compromised by long-term graft failure. Exendin-4, a glucagon-like peptide 1 receptor agonist, has in clinical studies been shown to improve insulin secretion in islet transplanted patients. However, little is known about the effect of exendin-4 on other metabolic parameters. We therefore aimed to determine what influence exendin-4 would have on revascularized minimal human islet grafts in a state of graft failure in terms of glucose metabolism, body weight, lipid levels and graft survival. Introducing the bilateral, subcapsular islet transplantation model, we first transplanted diabetic mice with a murine graft under the left kidney capsule sufficient to restore normoglycemia. After a convalescent period, we performed a second transplantation under the right kidney capsule with a minimal human islet graft and allowed for a second recovery. We then performed a left-sided nephrectomy, and immediately started treatment with exendin-4 with a low (20 mu g/kg/day) or high (200 mu g/kg/day) dose, or saline subcutaneously twice daily for 15 days. Blood was sampled, blood glucose and body weight monitored. The transplanted human islet grafts were collected at study end point and analyzed. We found that exendin-4 exerts its effect on failing human islet grafts in a bell-shaped dose-response curve. Both doses of exendin-4 equally and significantly reduced blood glucose. Glucagon-like peptide 1 (GLP-1), C-peptide and pro-insulin were conversely increased. In the course of the treatment, body weight and cholesterol levels were not affected. However, immunohistochemistry revealed an increase in beta cell nuclei count and reduced TUNEL staining only in the group treated with a low dose of exendin-4 compared to the high dose and control. Collectively, these results suggest that exendin-4 has a potential rescue effect on failing, revascularized human islets in terms of lowering blood glucose, maintaining bet

Veterinary nursing is now a well recognise professional route in the UK. There is considerable capacity within the industry to increase the number of veterinary nurses employed. As the veterinary care sector of the economy continues to expand the role of veterinary nurses under the direction of veterinary surgeons is predicted to grow. The need to train veterinary nurses to the highest standard accredited by the RCVS at both Diploma and Degree levels will continue to increase to meet this demand.

Veterinary Nursing in the UK is still a relatively young profession. Whilst it is known that there were animal nurses in existence in the late 1800’s the role and title ‘Veterinary Nurse’ has only been fully recognised since 1984. Opportunities to train to a national standardhowever have been in place since 1961. There are now 11,700 Registered Veterinary Nurses (RVN) in the UK, with ever increasing opportunities for career progression within general practice, referral practice, research, animal charities, pharmaceutical companies, boarding kennels and practice management. It is recognised that veterinary nursing is a vital qualification providing a critical role within the veterinary team, raising standards in veterinary practice, improving animal welfare and enhancing client communication. Veterinary Nurses must have the necessary training essential for the professional responsibilities that go with maintaining standards, autonomy and most importantly, the regulation of the profession.

Study Design. Randomized controlled trial. Objective. To compare the effects of full range of motion (ROM) and limited ROM isolated lumbar extension exercise upon full ROM lumbar extension strength, ROM, perceived pain, and disability. Summary of Background Data. Limited ROM is common in chronic low back pain as is lumbar extensor deconditioning. Limited ROM exercise is a common prescription but is yet to be empirically tested. Methods. Males (n = 21) and females (n = 17) with nonspecific chronic low back pain were initially recruited. Participants were randomized to either a full ROM (FullROM) or limited ROM (LimROM) training group or a control group. A total of 24 participants (males: n = 14, females: n = 10) completed the study and were included in analysis. The intervention lasted 12 weeks. FullROM and LimROM groups completed isolated lumbar extension resistance training once per week, performing one set of exercise at 80% of their maximal tested functional torque to failure. FullROM group trained through a full ROM. LimROM group trained through the mid 50% of their full ROM. Full ROM isolated lumbar extension strength, lumbar and standing ROM (Schobers test), perceived pain (visual analogue scale), and disability (Revised Oswestry Disability Index) were measured pre- and postintervention. Results. FullROM and LimROM significantly improved in full ROM lumbar extension strength, perceived pain, and disability compared with the control group. No changes occurred in lumbar or standing ROM. No significant differences were found between either FullROM or LimROM for any outcome measure. Changes in perceived pain and disability met minimal clinically important change values for FullROM (visual analogue scale, −30.3 + 25.76 mm and Oswestry Disability Index, −18.2 + 6.63 patients) and LimROM (visual analogue scale, −16.29 + 10.97 mm and Oswestry Disability Index, −12 + 5.16 patients). Conclusion. The results suggest that both FullROM and LimROM are equally effective in i

Highlights • A unique and novel CO2 release experiment in the marine environment. • Field-scale simulated leak of CO2 gas from a carbon capture and storage facility. • Experimental design and set-up for the QICS experiment, conducted during the summer of 2012. Abstract Carbon capture and storage is a mitigation strategy that can be used to aid the reduction of anthropogenic CO2 emissions. This process aims to capture CO2 from large point-source emitters and transport it to a long-term storage site. For much of Europe, these deep storage sites are anticipated to be sited below the sea bed on continental shelves. A key operational requirement is an understanding of best practice of monitoring for potential leakage and of the environmental impact that could result from a diffusive leak from a storage complex. Here we describe a controlled CO2 release experiment beneath the seabed, which overcomes the limitations of laboratory simulations and natural analogues. The complex processes involved in setting up the experimental facility and ensuring its successful operation are discussed, including site selection, permissions, communications and facility construction. The experimental design and observational strategy are reviewed with respect to scientific outcomes along with lessons learnt in order to facilitate any similar future.

Recent phylogenetic studies on Nematinae based on DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous DNA sequence datasets based on three genes (CoI, Cytb, and EF-1α), to include a fourth (NaK) and more genera. The analyses largely confirm the previous findings, particularly the existence of two well-supported large clades, Euura and Pristiphora, together comprising more than 75% of the species of Nematinae. Basal relationships within these two clades remain poorly resolved, mirroring the difficulties in delimiting genera based on morphology. In addition, a moderately supported small clade, Nematus, is found. The relationships between the Euura, Pristiphora, and Nematus clades are uncertain. Therefore, to stabilize the nomenclature we treat these clades as genera. This taxonomic treatment results in numerous new combinations of species names. The following synonymies are proposed for the available genus-group names.

Fossil fuel power generation and other industrial emissions of carbon dioxide are a threat to global climate1, yet many economies will remain reliant on these technologies for several decades2. Carbon dioxide capture and storage (CCS) in deep geological formations provides an effective option to remove these emissions from the climate system3. In many regions storage reservoirs are located offshore4, 5, over a kilometre or more below societally important shelf seas6. Therefore, concerns about the possibility of leakage7, 8 and potential environmental impacts, along with economics, have contributed to delaying development of operational CCS. Here we investigate the detectability and environmental impact of leakage from a controlled sub-seabed release of CO2. We show that the biological impact and footprint of this small leak analogue (<1 tonne CO2 d−1) is confined to a few tens of metres. Migration of CO2 through the shallow seabed is influenced by near-surface sediment structure, and by dissolution and re-precipitation of calcium carbonate naturally present in sediments. Results reported here advance the understanding of environmental sensitivity to leakage and identify appropriate monitoring strategies for full-scale carbon storage operations.

Experts in a skill produce movement-related cortical potentials (MRCPs) of smaller amplitude and later onset than novices. This may indicate that, following long-term training, experts require less effort to plan motor skill performance. However, no longitudinal evidence exists to support this claim. To address this, EEG was used to study the effect of motor skill training on cortical activity related to motor planning. Ten non-musicians took part in a 5-week training study learning to play guitar. At week 1, the MRCP was recorded from motor areas whilst participants played the G Major scale. Following a period of practice of the scale, the MRCP was recorded again at week 5. Results showed that the amplitude of the later pre-movement components were smaller at week 5 compared to week 1. This may indicate that, following training, less activity at motor cortex sites is involved in motor skill preparation. This supports claims for a more efficient motor preparation following motor skill training.

The influence of motor skill learning on movement-related brain activity was investigated using electroencephalography. Previous research has indicated that experienced performers display movement-related cortical potentials (MRCPs) of smaller amplitude and later onset compared to novices participants. Unfortunately, previous studies have lacked ecological validity with experimenters recording the MRCP prior to simple motor tasks and applying the results to more complex motor skills. This study replicated previous research using an ecologically valid motor skill; recording the MRCP from a group of experienced guitarists and a control group of non-musicians while they played a simple scale on the guitar. Results indicated no difference between groups in early motor planning. In contrast, the later, negative slope and motor potential components were of smaller amplitude and the negative slope began later in the experienced guitarists. The data may indicate that, for experienced guitarists, a reduced level of effort is required during the motor preparation phase of the task. These findings have implications for musical instrument learning as well as motor skill acquisition in general.

This study examined the presence and experience of muscle dysmorphia among current and former steroid-using recreational bodybuilders. The Muscle Dysmorphia Inventory was given to 60 male participants, with 9 of these being interviewed to examine the predisposing factors, characteristics, and negative consequences of muscle dysmorphia comprising Lantz, Rhea, and Mayhew’s (2001) conceptual model. Quantitative results from the MDI data showed no significant differences between current and former steroid users in their experiences of muscle dysmorphia. In contrast, interviews suggested that former users appeared to be more susceptible to some of the characteristics of muscle dysmorphia, including physique protec­tion and body distortion/dissatisfaction, which suggests perhaps a limitation in the amount of information that can be extracted from a questionnaire. These preliminary findings also raise concerns about the lack of a diagnostic tool available for the condition and are discussed in relation to Lantz et al.’s (2001) conceptual model.

Less than 50 years ago knowledge of the geology of the UK continental shelf (UKCS) was extremely limited. The BGS marine geoscience programme began about 40 years ago in response to the development of the UK oil and gas industry. The BGS was funded by the then Department of Energy to carry out a national mapping programme based on geophysical data, seabed samples and boreholes. By the 1990s, geological maps at a scale of 1:250 000 were published for the shelf regions showing seabed sediments, Quaternary geology and bedrock. The deeper water areas to the north and west continue to be explored with support from the oil industry. A series of regional reports, the offshore equivalent of the BGS regional guides, were published and reports for the Atlantic Margin will be published in 2010. MAREMAP is a new multidisciplinary environmental mapping programme designed to underpin the new marine industries and environmental issues.

This study examined the effects of differing frequencies of PETTLEP imagery on netball shooting performance. Thirty-two female participants were divided into four groups: PETTLEP imagery once per week (1x/wk), PETTLEP imagery twice per week (2x/wk), PETTLEP imagery three times per week (3x/wk) and a control. During the pre-test and post-test participants were required to complete a total of twenty shots from five different points within the shooting zone. They were awarded points (out of five) for each shot, giving a possible total of 100 points. The numbers of shots scored was also recorded. Following the pre-test, the imagery participants imaged the twenty shots the required number of times per week. The control group completed some netball specific stretching. Transfer tests were also completed to assess the transferability of the intervention to related tasks. Group x test ANOVAs for performance score and shots scored revealed a significant interaction effect (p<.01). Tukey tests revealed that the 3x/wk imagery group improved performance on both measures, whereas the 2x/wk, 1x/wk and control group did not. These results support the notion that PETTLEP imagery may be more effective if completed at least three times per week.

Based on neuroscience research, the PETTLEP model was developed by Holmes and Collins (2001). The model provides imagery guidelines which identify seven key factors (physical, environment, task, timing, learning, emotion, perspective) that should be included when developing interventions to maximise functional equivalence. This study explored the effect of a short-term PETTLEP imagery intervention, compared to `traditional' imagery, on a computer game: Need for Speed Underground 2 (EA games). Eighty participants were randomly assigned to one of four groups: PETTLEP imagery group, `traditional' imagery group, physical practice group and control group. After three practice attempts, pre-tests consisted of five attempts at the game. The game involved completing timed laps by manoeuvring a vehicle around a track using the computer's arrow keys. The PETTLEP group completed individualised response training, and then performed imagery sitting in front of the computer screen and repeatedly imaging themselves completing the task. The `traditional' imagery group was sat in a separate room, given individualised stimulus training and instructed to relax and close their eyes during imagery. The physical practice group performed the actual task. Each intervention lasted for forty-five minutes, immediately followed by the post-test, which again consisted of five attempts at the game. A group x test ANOVA showed that the PETTLEP imagery group and physical practice group both improved significantly from pre-test to post-test (p<0.05). However, there was no significant difference in the magnitude of their improvements. The traditional imagery and control groups showed no increase in performance from pre-test to post-test (p>0.05). The results strongly support the use of PETTLEP in enhancing performance on a cognitive task. Contrary to previous studies, PETTLEP was as effective as physical practice. This finding could have important implications for athletes returning from injury, suf

This study examined the application of a Langian imagery perspective (Lang, 1979, 1985) to a real-life sporting task, namely field hockey penalty flick performance. Twenty-seven novice hockey players were randomly assigned to either one of two imagery groups, or a control group. Participants in one of the imagery groups received stimulus and response proposition-laden imagery scripts, while the other received stimulus proposition-only scripts. All imagery participants imagined performing twenty penalty flicks three times per week for seven weeks, and control participants performed no imagery or physical practice during this period. Pre- and post-tests consisted often penalty flicks, with performances recorded for all groups. The response proposition group improved to a significantly (p [less than].05) greater degree than the stimulus proposition-only group, which in turn showed greater improvement (p [less than] .05) than the controls. Results support the application of bio-informational theory to sport and indicate that imagery scripts should be laden with response propositions to maximize their effectiveness.
