Using a simulation cell for exercise realism

A simulation cell or SimCell is an effective and flexible tool for control of emergency management exercises. It allows exercise participants to interact, via simulation, with a wide variety of nonplaying organizations and officials. Adapted from military application, the Chemical Stockpile Emergency Preparedness Program (CSEPP) applied, developed, and refined the SimCell concept for emergency management exercises. It has now been incorporated into national exercise guidance through the Homeland Security Exercise and Evaluation Program, and has been used in a wide variety of national, regional, and local exercises. This article reviews development of the SimCell concept in CSEPP, briefly surveys current practice incorporating SimCells in exercise control, and offers practical lessons-learned and tips on using a SimCell to best advantage. Lessons learned include using a SimCell as an exercise-control hub; preparing inject material for exercise controllers as part of the Master Scenario Event List; laying the groundwork for success through exercise player and controller training; developing protocol for SimCell communications; and capturing feedback from SimCell controllers for inclusion in the exercise evaluation reporting process. The SimCell concept is flexible and can be applied to a variety of exercise types and through a variety of methods.

Nonelite exercise‐related injuries: Participant reported frequency, management and perceptions of their consequences

This mixed methods study explored the frequency of sport/exercise-related injuries in nonelite sport, participant-reported management and perceptions of potential injury consequences. Focus group participants, who trained two to four times a week and had previously sustained musculoskeletal sports-related injuries, reported seeking medical advice secondary to advice from teammates or online research. General practitioners were viewed as gatekeepers to specialist secondary care and less able to effectively treat sport-related injuries. Participants displayed limited awareness of potential future implications of injury, and considered physical and psychological benefits of exercise more valuable than potential injury-associated risks. In the survey of physically active people, over half reported sustaining an exercise-related injury (562/1002, 56%). Previously injured respondents were less likely to consider consulting a health professional for injury-related advice than those with no injury history (45% vs 64%; P < 0.001) and more likely to continue exercising despite injury (51% vs 37%; P < 0.001). Concerns about injuries largely related to short-term issues; only 32% were concerned about possible long-term joint problems including osteoarthritis. Exercise-related injury was common in nonelite exercise participants. There was some dissatisfaction with care pathways for sports-related injuries and a lack of awareness about appropriate injury management and potential consequences of injury, particularly in the long-term.

Older Adults Recently Discharged from the Hospital: Effect of Aerobic Interval Exercise on Health‐Related Quality of Life, Physical Fitness, and Physical Activity

To compare the effect of high-intensity aerobic interval exercise (HIA) with home-based exercise (HB) in older adults with chronic disease soon after discharge from the hospital. Randomized controlled trial. Hospital. Community-dwelling older adults aged 70 to 92 (N = 115) were recruited while in the hospital. After discharge, they were randomized to HIA group (n = 59) or HB (n = 56). High-intensity aerobic interval exercise (HIA) consisted of endurance, strength, and balance exercises. The HB consisted of low-intensity exercises and telephone follow-up from a physical therapist. Health-related quality of life (HRQOL) was assessed using the Medical Outcomes Study 36-item Short Form Survey, physical fitness was measured using the Senior Fitness Test, and physical activity was assessed using the Physical Activity Scale for the Elderly. Intention-to-treat analysis showed that both groups improved their HRQOL and physical activity after 3 months. Improvements on the Senior Fitness Test (chair stand, arm curl and 6-minute walk (6MWT)) were significantly greater in the HIA group than the HB group. The mean difference was 25.9 m on the 6MWT (P = .001, effect size d = 0.2), 1.3 per 30 seconds on the chair stands mean (P = .001, effect size d = 0.3), and 1.6 per 30 seconds on the arm curl (P = .001, effect size d = 0.4). High-intensity aerobic interval exercise (HIA) participants significantly improved their physical fitness. Both groups increased their HRQOL and physical activity. The findings suggest that exercise therapy should be incorporated as a part of the treatment for older people at risk for functional decline.

Does Pilates-Based Exercise Improve Postural Alignment in Adult Women?

A randomized, controlled trial was conducted to determine the effect of Pilates-based exercise on postural alignment. Seventy-four adult women (mean age ± SD, 34.9 ± 16.4 years) were randomized to a Pilates-based mat class (n = 40) or a control group (n = 34). Pilates-based exercise participants were taught the Initial Mat of Body Control Pilates for 6 months, twice a week, for 60 minutes per session; the control group received no exercise intervention. Repeated measurements were performed at baseline, 3 months, and 6 months of the frontal alignment of the thoracolumbar spine, shoulder, and pelvis, and sagittal alignment of the head and pelvis. No differences were found in either group, over time, on frontal alignment of the thoracolumbar spine and pelvis. The experimental group showed significant improvements in frontal alignment of the shoulder and sagittal alignment of the head and pelvis at 6 months. The Pilates-based exercise enhanced some parameters of the postural alignment of women, as measured by frontal alignment of the shoulder and sagittal alignment of the head and pelvis. The significant improvement in sagittal alignment of the head may imply that 6 months of Pilates-based exercise enhances sagittal alignment of the cervical or thoracic spine.

Multi-Disciplinary Simulation Training for Anaesthetic Practitioners

A multi-disciplinary simulation training course devised and implemented at Morriston Hospital is described. The participants in the simulation exercise included both medical and non-medical professionals in a pilot study intended to analyse the effectiveness of a multi-disciplinary approach to this training technique. Questionnaires completed by the participants both immediately after the training session and again some months later highlight the desirability of this multi-disciplinary training. The success of the training course and the lessons learned from its implementation are being used to plan a similar second session in the near future.

Differential Effects of Cardiovascular and Resistance Exercise on Functional Mobility in Individuals With Advanced Cancer: A Randomized Trial

ObjectiveTo compare the effects of resistance and cardiovascular exercise on functional mobility in individuals with advanced cancer. DesignProspective, 2-group pretest-posttest pilot study with randomization to either resistance or cardiovascular exercise mode. SettingComprehensive community cancer center and a hospital-based fitness facility. ParticipantsVolunteer sample of individuals (N=66; 30 men; 36 women; mean age, 62y) with advanced cancer recruited through the cancer center, palliative care service, rehabilitation department, and a local hospice. InterventionsTen weeks of individualized resistance or cardiovascular exercise, prescribed and monitored by oncology-trained exercise personnel. Main Outcome MeasuresFunctional mobility was assessed using the Short Physical Performance Battery (SPPB); self-reported pain and fatigue were assessed secondarily using visual analog scales. Data were analyzed using a split plot 2×2 analysis of variance (α=.05). ResultsFifty-two patients (78.8%) completed the study: 23 (67.7%) of 34 patients in the resistance arm and 29 (90.6%) of 32 patients in the cardiovascular arm. No participant withdrew because of study adverse events. Ten-week outcomes (n=52) included a significant increase in SPPB total score (P<.001), increase in gait speed (P=.001), and reduction in fatigue (P=.05). Although cardiovascular exercise participants had a modestly greater improvement in SPPB total score than resistance training participants (F1,49=4.21, P=.045), the difference was not confirmed in a subsequent intention-to-treat analysis (N=66). ConclusionsIndividuals with advanced cancer appear to benefit from exercise for improving functional mobility. Neither resistance nor cardiovascular exercise appeared to have a strong differential effect on outcome.

Perceptions of participating in high-intensity functional exercise among older people dependent in activities of daily living (ADL)

The purpose of the study was to evaluate how older people, dependent in ADL perceive their participation in a high-intensity, functional exercise program compared to the perceptions of those participating in a control activity. Forty-eight older people living in residential care facilities answered a questionnaire about their perceptions of participating in an activity for three months. They were aged 65–98, had a mean score of 24 on Mini Mental State Examination (MMSE) and 14 on Barthel ADL Index. The participants had been randomized to exercise (n=20) or control activity (n=28). Differences in responses between exercise and control activity were evaluated using logistic and ordinal regression analyses. The results show that a majority of the exercise group perceived positive changes in lower limb strength, balance, and in the ability to move more safely and securely compared to a minority of the control group (p<0.001). Significantly more respondents in the exercise activity answered that they felt less tired due to the activity (p=0.027) and that they prioritized this activity above other activities (p=0.010). More exercise participants reported that meeting for three months was too short, and fewer that it was too long compared to the control group (p=0.038). This study shows that older people living in residential care facilities, dependent in ADL, and with mild or no cognitive impairment had positive perceptions about participating in high-intensity functional exercise. The findings support the use of a high-intensity exercise program in this population of older people.

Dextrose Prolotherapy for Knee Osteoarthritis: A Randomized Controlled Trial

Knee osteoarthritis is a common, debilitating chronic disease. Prolotherapy is an injection therapy for chronic musculoskeletal pain. We conducted a 3-arm, blinded (injector, assessor, injection group participants), randomized controlled trial to assess the efficacy of prolotherapy for knee osteoarthritis. Ninety adults with at least 3 months of painful knee osteoarthritis were randomized to blinded injection (dextrose prolotherapy or saline) or at-home exercise. Extra- and intra-articular injections were done at 1, 5, and 9 weeks with as-needed additional treatments at weeks 13 and 17. Exercise participants received an exercise manual and in-person instruction. Outcome measures included a composite score on the Western Ontario McMaster University Osteoarthritis Index (WOMAC; 100 points); knee pain scale (KPS; individual knee), post-procedure opioid medication use, and participant satisfaction. Intention-to-treat analysis using analysis of variance was used. No baseline differences existed between groups. All groups reported improved composite WOMAC scores compared with baseline status (P <.01) at 52 weeks. Adjusted for sex, age, and body mass index, WOMAC scores for patients receiving dextrose prolotherapy improved more (P <.05) at 52 weeks than did scores for patients receiving saline and exercise (score change: 15.3 ± 3.5 vs 7.6 ± 3.4, and 8.2 ± 3.3 points, respectively) and exceeded the WOMAC-based minimal clinically important difference. Individual knee pain scores also improved more in the prolotherapy group (P = .05). Use of prescribed postprocedure opioid medication resulted in rapid diminution of injection-related pain. Satisfaction with prolotherapy was high. There were no adverse events. Prolotherapy resulted in clinically meaningful sustained improvement of pain, function, and stiffness scores for knee osteoarthritis compared with blinded saline injections and at-home exercises.

Endurance exercise beneficially affects ambulatory blood pressure

Exercise is widely recommended as one of the key preventive lifestyle changes to reduce the risk of hypertension and to manage high blood pressure (BP), but individual studies investigating the effect of exercise on ambulatory BP have remained inconclusive. Therefore, the primary purpose of this systematic review and meta-analysis was to determine the effect of aerobic endurance training on daytime and night-time BP in healthy adults. A systematic literature search was conducted using PubMed and Cochrane Controlled Clinical trial registry from their inception to May 2012. Randomized controlled trials of at least 4 weeks investigating the effects of aerobic endurance training on ambulatory BP in healthy adults were included. Inverse weighted random effects models were used for analyses, with data reported as weighted means and 95% confidence limits. We included 15 randomized controlled trials, involving 17 study groups and 633 participants (394 exercise participants and 239 control participants). Overall, endurance training induced a significant reduction in daytime SBP [-3.2 mmHg, 95% confidence interval (CI), -5.0 to-1.3] and daytime DBP (-2.7 mmHg, 95% CI, -3.9 to -1.5). No effect was observed on night-time BP. The findings from this meta-analysis suggest that aerobic endurance exercise significantly decreases daytime, but not night-time, ambulatory BP.

Cross-cultural invariance of the basic psychological needs in exercise scale and need satisfaction latent mean differences among Greek, Spanish, Portuguese and Turkish samples

ObjectivesThe present study examined the extent to which scores from the Basic Psychological Needs in Exercise Scale are measurement invariant across Greek, Spanish, Portuguese, and Turkish samples of exercise participants. DesignA cross-sectional design wherein responses were analyzed from 504 Greek participants, 518 Spanish participants, 989 Portuguese participants, and 686 Turkish participants. MethodsData on exercise participants' need satisfaction were collected using the Basic Psychological Needs in Exercise Scale (Vlachopoulos & Michailidou, 2006) after back translation for the languages involved in the study. ResultsMulti-sample confirmatory factor analyses showed that BPNES scores were largely invariant at the configural, metric, and strong invariance levels, but not at the strict invariance level for Spanish, Portuguese, and Turkish samples compared to the Greek sample. Portuguese participants reported higher levels of satisfaction for all three needs compared to Greek participants, while for Spanish participants this was the case only for competence and relatedness. Turkish participants did not differ from Greek participants. ConclusionsThe present findings support valid cross-cultural comparisons at the latent variance/covariance level and the latent/observed mean level of the constructs of autonomy, competence, and relatedness using the BPNES.

Gene Expression Changes in Adipose Tissue with Diet- and/or Exercise-Induced Weight Loss

Adipose tissue plays a role in obesity-related cancers via increased production of inflammatory factors, steroid hormones, and altered adipokines. The impact of weight loss on adipose tissue gene expression may provide insights into pathways linking obesity with cancer risk. We conducted an ancillary study within a randomized trial of diet, exercise, or combined diet + exercise versus control among overweight/obese postmenopausal women. In 45 women, subcutaneous adipose tissue biopsies were conducted at baseline and after 6 months, and changes in adipose tissue gene expression were determined by microarray with an emphasis on prespecified candidate pathways as well as by unsupervised clustering of more than 37,000 transcripts (Illumina). Analyses were conducted first by randomization group and then by degree of weight change at 6-months in all women combined. At 6 months, diet, exercise, and diet + exercise participants lost a mean of 8.8, 2.5, and 7.9 kg (all P < 0.05 vs. no change in controls). There was no significant change in candidate gene expression by intervention group. In analysis by weight change category, greater weight loss was associated a decrease in 17β-hydroxysteroid dehydrogenase-1 (HSD17B1, Ptrend < 0.01) and leptin (LEP, Ptrend < 0.01) expression, and marginally significant increased expression of estrogen receptor-1 (ESR1, Ptrend = 0.08) and insulin-like growth factor-binding protein-3 (IGFBP3, Ptrend = 0.08). Unsupervised clustering revealed 83 transcripts with statistically significant changes. Multiple gene expression changes correlated with changes in associated serum biomarkers. Weight loss was associated with changes in adipose tissue gene expression after 6 months, particularly in two pathways postulated to link obesity and cancer, that is, steroid hormone metabolism and IGF signaling.

The correlation between the plenitude of fall prevention programs and fall incidents in community-level: A J-MACC study

ObjectiveThe purpose of this study was to examine the relationship between the number of participants partaking in fall prevention-related programs and fall rates in the community. MethodA cross-sectional survey was conducted in Sakyo Ward, Kyoto City, Japan as part of the Japan Multi-center Aging Cohort for Care prevention study. Data from 6423 healthy community-dwelling elderly adults living in 20 districts were used to identify the districts with high fall rates. An alternate survey was conducted to collect information on fall prevention-related programs held in each district between April 2010 and March 2011. Using the Mantel-Haenszel chi-square test, we identified districts with high fall rates and compared the number of participants in each fall prevention-related program between districts with high fall rates and other districts using the Mann-Whitney U test and chi-square test. ResultsThe districts determined as “non-high fall rate” had significantly more participants in exercise and education programs than the “high fall rate” districts (p=0.02). The “non-high fall rate” districts also had more participants than the “high fall rate” districts in public group exercise, private volunteer-led group exercise, and pamphlet distribution; however, this number was not significant. ConclusionInterventions with exercise and educational aspects may be effective in preventing falls at the community level.

Acute exercise attenuates negative affect following repeated sad mood inductions in persons who have recovered from depression.

Identifying factors that may protect individuals from developing Major Depressive Disorder (MDD) in the face of stress is critical. In the current study we experimentally tested whether such a potentially protective factor, engaging in acute exercise, reduces the adverse effects of repeated sad mood inductions in individuals who have recovered from depression. We hypothesized that recovered depressed participants who engage in acute exercise report a smaller increase in negative affect (NA) and a smaller decrease in positive affect (PA) when exposed to a repeated sad mood induction (i.e., habituation), whereas participants who do not exercise show sensitization (i.e., increased NA and decreased PA in response to a repeated adverse stimulus). Forty-one women recovered from MDD and 40 healthy control women were randomly assigned to either exercise for 15 minutes or quiet rest. Afterward, participants were exposed to two sad mood inductions and reported their levels of affect throughout the study. Recovered depressed participants who had not exercised exhibited higher NA after the second sad mood induction, a finding consistent with sensitization. In contrast, both recovered depressed participants who had engaged in acute exercise and healthy control participants showed no increase in NA in response to the repeated sad mood induction. Participants who exercised reported higher PA after the exercise bout; however, our hypothesis concerning reported PA trajectories following the sad mood inductions was not supported. Results suggest that exercise can serve as a protective factor in the face of exposure to repeated emotional stressors, particularly concerning NA in individuals who have recovered from depression.

Indirect measures of substrate utilisation following exercise-induced muscle damage

This study investigated whether exercise-induced muscle damage (EIMD) resulted in changes to whole-body substrate utilisation during exercise performed during the subsequent 48 hours. Eight males (31±6 years) performed 30 minutes of bench-stepping exercise. One leg performed eccentric contractions (Ecc) by lowering the body whilst the control leg performed concentric contractions (Con) by raising the body. On the two days following bench-stepping exercise participants performed measures of muscle function on an isokinetic dynamometer and undertook a bout of one leg cycling exercise, at two differing workloads, with the first workload (WL1) at 1.5±0.25 W/kg and the second workload (WL2) at 1.8±0.25 W/kg with each leg. Expired respiratory gases were collected during cycling to estimate whole body substrate utilisation. There were significant decrements in measures of muscular performance (isometric force, concentric and eccentric torque) and increased perception of soreness in Ecc compared with Con (P < 0.05). The effect of the Ecc treatment on substrate utilisation during one-legged cycling revealed a significant trial×time interaction with higher rates of CHO oxidation in the Ecc condition compared with Con that were further increased 48 hours later (P = 0.02). A significant treatment×time×effort interaction (P < 0.01) indicated the effect of the treatment altered as workload increased with higher rates of CHO oxidation occurring in WL2. This is consistent with greater reliance upon muscle glycogen. Suggesting that in EIMD, reductions in strength and increased feelings of soreness can be associated with greater reliance upon intramuscular CHO oxidation, than lipid, during subsequent concentric work.

Age specific differences in sports participation inDenmark – Is development caused by generation, life phase or time period effects?

Leisure time sport and exercise underwent remarkable development in Denmark between 1964 and 2007. Today’s sport and exercise participants represent all age groups from young children to seniors, and the latest survey representative of the Danish nation from 2007 showed that participation level no longer resembles a linear drop with increased age as has earlier been the case. The aim of the article is to analyse whether sport and exercise participation has developed as a means of generation, life phase or periodical effects. In the analysis only data from 1975, 1987, 1998 and 2007 will be in-cluded. The results show that sport and exercise participation is affected by all three theo-retical perspectives. Periodical effects have the greatest impact on development – and bigger for women than men – followed by life phase (considering a linear drop in participation level with older stages in life) and generational effects. Further, an alternative model of a curve-linear life phase effect is occurring in 2007. With this in mind the paper presents two perspectives of interpretations that sport providers need to consider, particularly in order to organise activities and to accommodate needs and demands in different life phases and generations in the future.

Applying Single-Case Design Innovations to Research in Sport and Exercise Psychology

The purpose of this article is to illustrate how two innovations in single-case research design, the range-bound changing criterion and the distributed criterion designs, have recently emerged and how these designs might apply to sport and exercise psychology and sport performance. Both design innovations appear most suited to interventions that use, or include, common psychological skills training techniques, such as self-talk and goal-setting, together with more general behavioral self-management approaches. Investigators are encouraged to consider applying these two design innovations to contexts where researchers are interested in shaping or developing behaviors within sport and exercise participants.

Exercise performance and neuromuscular activity at a fixed level of RPE following manipulation of peripheral physiological status

PURPOSE: to analyse the effect of manipulation of peripheral physiological status on performance and neuromuscular activity during cycling at a fixed level of RPE. METHODS: following familiarisation trials, seven well trained individuals completed two exercise trials following ingestion of 0.2g.kg-1 NaHCO3 or a CaCO3 placebo which were performed in a randomised and blind manner. During exercise participants were required to cycle at exercise intensity equivalent to their perception of an RPE of 16 on the Category Ratio Scale. Blood pH was measured pre- and post-exercise, and power output, EMG activity in the active musculature, and heart rate were recorded continuously throughout exercise. Exercise was terminated when power output fell below 80% of the average recorded over the first 3 minutes of each trial. RESULTS: pre-exercise pH was higher following NaHCO3 ingestion, but post-exercise values did not differ between NaHCO3 and placebo trials. Exercise duration was 21% longer following NaHCO3 than the placebo, but no significant differences were found in power output or heart rate between trials at any point. EMG activity was higher throughout NaHCO3 trials. CONCLUSIONS: the findings of this study suggest that NaHCO3 ingestion enhanced exercise duration by allowing an increased volume of exercise to be performed prior to individuals reaching individual critical threshold values for pH. Lower neuromuscular activity despite a similar power output following NaHCO3 suggests that perceptions of effort may be based on absolute work rates rather than afferent physiological feedback, and that the work rate is achieved through regulation of efferent neural drive.

Lessons learnt during a complex, multicentre cluster randomised controlled trial: the ProAct65+ trial

BackgroundFailure to recruit to target or schedule is common in randomized controlled trials (RCTs). Innovative interventions are not always fully developed before being tested, and maintenance of fidelity to the intervention during trials can be problematic. Missing data can compromise analyses, and inaccurate capture of risks to participants can influence reporting of intervention harms and benefits.In this paper we describe how challenges of recruitment and retention of participants, standardisation and quality control of interventions and capture of adverse events were overcome in the ProAct65+ cluster RCT. This trial compared class-based and home-based exercise with usual care in people aged 65 years and over, recruited through general practice. The home-based exercise participants were supported by Peer Mentors.Results(1) Organisational factors, including room availability in general practices, slowed participant recruitment so the recruitment period was extended and the number invited to participate increased. (2) Telephone pre-screening was introduced to exclude potential participants who were already very active and those who were frequent fallers. (3) Recruitment of volunteer peer mentors was difficult and time consuming and their acceptable case load less than expected. Lowering the age limit for peer mentors and reducing their contact schedule with participants did not improve recruitment. (4) Fidelity to the group intervention was optimised by introducing quality assurance observation of classes by experienced exercise instructors. (5) Diaries were used to capture data on falls, service use and other exercise-related costs, but completion was variable so their frequency was reduced. (6) Classification of adverse events differed between research sites so all events were assessed by both sites and discrepancies discussed.ConclusionsRecruitment rates for trials in general practice may be limited by organisational factors and longer recruitment periods should be allowed for. Exercise studies may be attractive to those who least need them; additional screening measures can be employed to avoid assessment of ineligible participants. Enrolment of peer mentors for intervention support is challenging and needs to be separately tested for feasibility. Standardisation of exercise interventions is problematic when exercise programmes are tailored to participants’ capabilities; quality assurance observations may assure fidelity of the intervention. Data collection by diaries can be burdensome to participants, resulting in variable and incomplete data capture; compromises in completion frequency may reduce missing data. Risk assessments are essential in exercise promotion studies, but categorisation of risks can vary between assessors; methods for their standardisation can be developed.Trial registrationISRCTN43453770

“Imageless” Spatial and Temporal Rules Can Be Tested and Refined by Constructing Vivid Visual and Auditory Images

In this computerized study, research participants completed both Marks' (1973) Vividness of Visual Imagery Questionnaire and Kunzendorf's (1979) Vividness of Auditory Imagery Questionnaire and, immediately thereafter, completed either a visuo-spatial rule-development exercise or an audio-temporal rule-development exercise. During the visuo-spatial exercise, participants were administered 20 four-alternative quizzes regarding the schematic rules of 3-point perspective (3PP) and, between quizzes, were instructed to figure out the rules by constructing visual images that serve to test their developing schema. During the audio-temporal exercise, participants were administered 24 two-alternative quizzes regarding artificial grammatical rules and, between quizzes, were instructed to figure out the rules by generating auditory images that serve to test their developing grammar. Across 83 participants in the visuo-spatial rule-development exercise, greater development of 3PP rules correlated significantly with greater vividness of visual imagery, but not auditory imagery. Conversely, across 94 participants in the audio-temporal rule-development exercise, greater development of grammatical rules correlated significantly with greater vividness of auditory imagery, but not visual imagery. In the historical context of null correlations between image vividness and problem-solving success, the current correlational findings provide modality-specific support for Kunzendorf and Reynold's (2004-2005) and Kunzendorf and Buker's (2008-2009) thesis that the vivid imager's construction of sensory images from imageless rules facilitates the testing and refinement of newly hypothesized rules, but does not facilitate the application of previously developed rules to new problems.

Addicted to Exercise

The study examines the factor structure, internal consistency, concurrent and discriminant validity, and test-retest reliability of the Exercise Dependence Scale-Revised scores (EDS-R: Symons-Downs, Hausenblas, &amp; Niggs, 2004 ) in a sample of Greek exercise participants. The Greek translation of the EDS-R was completed by 581 exercise participants along with measures of exercise addiction. Confirmatory factor analysis provided support for the hypothesized EDS-R correlated 7-factor model along with evidence for strong item loadings and factor discriminant validity. Further evidence emerged in favor of the internal consistency, concurrent validity, and test-retest reliability of the translated EDS-R scores. The results provide initial support for various aspects of the validity and reliability of the translated-into-Greek EDS-R scores.
