ObjectiveTo evaluate the impact of a wearable activity tracker used to encourage physical activity, on disease flares in patients with spondyloarthritis (SpA).MethodsThis randomized controlled trial involved randomizing 108 patients with SpA into tracker and nontracker groups. The participants were then subjected to assessments of disease activity, performance (6-minute walk test), and quality of life (QOL; 36-item Short Form Health Survey) at the 12th, 24th, and 36th week. The primary outcome was the change in the frequency of flare episodes (categorized as no flare, flare in ≤ 3 days, and flare in > 3 days) between baseline and 12 weeks.ResultsThe results of the study showed that at the 12th week, the mean change (∆) of the number of flares improved in both groups: −0.32 (95% CI −0.66 to 0.02) and −0.38 (95% CI −0.68 to −0.09) in the tracker and nontracker group, respectively. However, the between-group differences were insignificant (P = 0.87). Performance scores improved in both groups at the 12th, 24th, and 36th week (all P < 0.01). The different dimensions of QOL also improved at the 12th week (P < 0.01). Conversely, moderate flares (P < 0.01) and performance (P < 0.01) improved over time; however, the influence over time of a wearable activity tracker was not significant (P = 0.29 and P = 0.66, respectively).ConclusionThe use of a wearable activity tracker did not affect the number of flares, performance, or QOL of patients with SpA. Nevertheless, this study confirmed the benefits of physical activity on flares, disease activity, QOL, and physical performance in patients with SpA.

This article focuses on two popular sports that can put male athletes at risk of developing an eating disorder: bodybuilding and running. Bodybuilders concentrate on gaining muscle mass and runners on leaning body mass. Based on the trans-contextual model of motivation, this study aimed to better understand the psychological mechanisms underlying eating disorders in these athletes. In all, 272 male bodybuilders and 217 male runners completed measures of sport motivation, theory of planned behavior variables (i.e., attitude, subjective norm, perceived behavioral control, and intention to gain muscle mass/lean body mass), and eating disorders (dieting, control, and bulimia behaviors). The results revealed satisfactory fit indices for both samples. Autonomous and controlled motivations for sport were positively directly and indirectly related to eating disorders in these athletes. This motivational mechanism needs more in-depth investigation, and motivational profiles might help distinguish athletes with and without eating disorders.

Background Physical activity (PA) is a proven therapeutic tool to increase the quality of life and life expectancy in people with cystic fibrosis (pwCF). Despite this, the PA level of pwCF is lower than recommended. Objectives This study was conducted to identify the barriers to and facilitators of PA in adults with CF with heterogeneous severity. Methods Twenty adults with CF (mean age = 33.3±11.7 years, mean FEV1% = 50.55±20.4%) were recruited from two specialized centers and interviewed about the factors that limit and facilitate their PA. The collected data were transcribed, coded and analyzed using deductive and inductive methods. Results Barriers and facilitators were classified into physical, psychological and environmental dimensions. The main barriers were fatigue, breathing difficulties, lack of available facilities, negative perceptions of PA and perceived health risks. The most important facilitators were respiratory benefits, well-being, and social support. Conclusion Although some barriers and facilitators were similar to those found in children with CF or adults from other vulnerable populations, others were specific to adults with CF, such as the risk of cross-contamination and transplant preparation. The comprehensive study of the barriers and facilitators in adults will enhance PA counseling for pwCF and help improve their compliance with PA recommendations.

Background Elderly's sustainable engagement in an active lifestyle is a complex phenomenon, implying a plurality of physical, psychological and environmental barriers and facilitators. One of the key factors limiting physical activity (PA) in rural area is the lack of accessibility to PA offers. The use of videoconferencing is a promising solution in terms of acceptability and efficiency to promote PA. However, the acceptability (initial stage of the technology adoption process) of the videoconferencing is still underexplored, as well as its role in promoting PA in rural areas. The purpose of this study was to explore, through the perceptions of the elderly and policymakers, the mechanisms of acceptability of the development of PA interventions using videoconferencing for elderly living in rural areas. Methods Elderly (n = 10) and policymakers (n = 12) from 11 different rural town of the South of France participated in the study. Semi-structured individual interviews were conducted, where a video presentation of PA interventions using videoconferencing was played as support. The interview guide assessed the acceptability of this type of intervention through the following themes: (1) perceptions of benefits, (2) barriers, and (3) intentions of use. Results Preliminary results showed shared perceptions between elderly and policymakers for barriers (e.g., lack of real social ties, lack of technological equipment) and benefits (e.g., breaking loneliness, overcome weather conditions). However, intentions of use are heterogeneous according to individual characteristics (e.g., “young” elderly between 60 to 65 years are more favourable to the use of technologies) and the specificity of towns (e.g., in the smallest towns with less than 500 people, elderly are less inclined to change their habits). Conclusions This study showed that the development of videoconferencing PA intervention could be accepted by elderly living in rural areas, taking into account some conditions (e.g., offer as punctual and non-regular use, set up individual support for the use of technology). Additional quantitative studies should be conducted for a more comprehensive understanding of the factors influencing the videoconferencing PA intervention acceptability in rural areas.

Background Technology-based physical activity interventions (TbPAI) have recently been shown to be effective for care of obese women (Cotie et al., 2018). Therefore, it is necessary to assess the acceptability of TbPAI to ensure dissemination and usage in the treatment of obesity (Venkatesh et al., 2012). As such, the purpose of this study was to: (1) identify acceptability profiles of three TbPAI in obesity care (e.g., active video games, mobile applications, videoconferencing); (2) examine the issues of consistency or change of acceptability profiles for the same individual across the three technology; and (3) explore whether technology acceptability profiles were associated with motivation for physical activity (PA), general causality orientations for PA and sociodemographic data. Methods Three hundred and twelve women with a mean age of 30.7 (SD=7.1) years, and a mean BMI of 34.9 (SD=9.2) kg/m2 were recruited from health services that provide obesity management. Enrolled participants completed an online survey including the following measures: motivation for PA, general causality orientations for PA, TbPAI acceptability for the three selected technologies based on the UTAUT2 model (Venkatesh et al., 2012), and sociodemographic data. Ethical approval was gained by local committee, and informed consent were obtained from the participants before data collected. We used a Latent Profile Transition Analysis (LPTA) approach. Results A 2-class model (high and low acceptability) best described latent classes for each technology. Acceptability profiles changed over the technologies. Among our sample, only 8.0% (n = 25) of women have low acceptability of all technologies, and 57.7% (n = 180) have high acceptability of all technologies. The covariate effect estimates showed significant effects of: (a) age and control causality orientation on video games acceptability profiles, (b) intrinsic motivation and impersonal causality orientation on videoconferencing profiles, and (c) control and impersonal causality orientations on mobile applications profiles. Conclusions A LPTA approach may prove usefulness in understanding TbPAI acceptability in the obesity treatment and have implications for implementation and dissemination of such technologies.

Background The effectiveness of technology-based physical activity interventions (TbPAI) has recently been shown for obese women (Cotie et al., 2018). However, the acceptability of TbPAI has often been considered through the measure of satisfaction, and not through the theoretical concepts of acceptability. To our knowledge, TbPAI acceptability has never been explored in bariatric surgery. The purpose of this study was to explore in-depth the facilitators of and barriers to TbPAI acceptability according to the theoretical concepts of the UTAUT2 model (Venkatesh et al., 2012). Methods Twenty-six women with a mean age of 32.9 (SD=5.5) and a BMI of 30.1 (SD=6.5) were interviewed at least 6 months after bariatric surgery. Participants were selected in a panel of obese women who completed measures of acceptability (Hayotte et al., 2020) for each TbPAI, and expressed preference in using at least one of the technologies (10 active video games, 10 mobile application, 6 videoconferencing). Interviews were audio-recorded, transcribed verbatim, and analysed using thematic content analysis. Ethical approval was gained by local committee, and informed consent were obtained from the participants before data collection. Results Autonomy, monitoring and feedback were identified as facilitators of mobile application acceptability. Lack of external regulation was perceived as a barrier. Regarding the acceptability of active video games, the playful dimension was perceived as a facilitator, despite several participants showing resistance to any game experience. For videoconferencing, individualization of practice was perceived as a facilitator, whereas appointment constraints were seen as a barrier. Conclusions These preliminary results highlighted areas to be considered for the dissemination of these TbPAI in a healthcare setting. These results will also help to better individualize TbPAI counselling according to the barriers and facilitators identified.

Background The continued prevalence of positive samples to banned performance-enhancing drugs confirms the importance to maintain the anti-doping efforts. Though the role of socio-cognitive variables in doping attitudes is well identified (e.g., Ntoumanis et al., 2014), the role of implicit processes remains sparsely studied in sports’ doping, especially in high level cyclists. While the potential of traditional computer-IAT has been developed to capture individuals’ implicit attitudes toward doping (Brand et al., 2014ab; Schindler et al., 2015), paper-and-pen IAT offers unquestionably ease-of-administration prospects (Chan and al., 2017). The aim of this study was thus to test and provide a preliminary validation of a French paper-and-pen IAT as an alternative method to measure implicit attitudes toward doping: the IAT-Dop. Method This work was based on the testing procedure of the paper-and-pen Personalized Single-Category IAT test (i.e., p&p SC-IAT-P) of Bardin et al. (2016), which we enriched with the procedure of Boateng et al. (2018). This paper was built around four studies: (a) the first study consisted in the development of a preliminary version of the IAT-Dop, (b) the second study measured the dimensionality and criterion validity of the IAT-Dop to confirm the structure of the p&p version, (c) the third study verified its test-retest reliability, and (d) the fourth study explored the relations between the p&p and computerized versions of the IAT-Dop as a first approach to construct validity. Results Study 1 developed a preliminary French version of the IAT-Dop based on Chan et al.’s IAT proposal (2017). Study 2 provided preliminary support to the dimensionality and criterion validity of the tool. Study 3 demonstrated the test-retest reliability of the instrument. Finally, Study 4 suggested the construct validity of the IAT-Dop through a significant correlation between the computerized and p&p versions. Conclusion The IAT-Dop is a preliminary tested French-language version of a tool for measuring athletes’ implicit attitudes toward doping, with the advantages of simplicity, low cost, and quick administration. This tool should contribute to the better assessment and understanding of the mechanisms related to doping and may be a useful new indicator in the evaluation of prevention programs.

Background The drive for muscularity behaviors are very common in male athletes, especially in male bodybuilders. Studies have shown that drive for muscularity is a risk factor for eating disorders and muscle dysmorphia. Although several psychological variables have been related to drive for muscularity (e.g. body dissatisfaction), little is known about the motivational mechanisms underlying drive for muscularity.This study applied the trans-contextual model of motivation to the drive for muscularity behaviors of male bodybuilders at risk of developing muscle dysmorphia. The relationships between self-determination theory constructs and drive for muscularity behaviors, via the theory of planned behavior variables were examined. Methods A total of 175 Swiss male bodybuilders (Mage = 27.34; SDage = 7.53) completed measures on motivation for sport, theory of planned behavior variables, and drive for muscularity behaviors. They practiced bodybuilding from three to 24 hours per week and had done so for 7.19 years on average. A series of path analyses was performed to determine the final model. Results The fit indices of the final model were satisfactory: X2 (11) = 13.81; p = .244; TLI = .98; CFI = .99; RMSEA = .04. The model explained 29% of the variance of drive for muscularity behaviors. The final path analysis supported the motivational sequence, with autonomous motivation for sport showing a positive, significant and indirect association with the drive for muscularity behaviors via perceived behavioral control and intention to gain muscle mass, and controlled motivation for sport showing a positive association with the drive for muscularity behaviors both directly and via attitude and intention to gain muscle mass. Conclusions It was concluded that the trans-contextual model of motivation applies only partially to the drive for muscularity behaviors in male bodybuilders. Preventive actions may be important for male bodybuilders, who focus on gaining muscle mass. Specifically, such actions should be directed toward helping them to avoid developing controlled motivation because, although motivation for sport of any kind can be a direct or indirect risk factor for the development of deviant behavior, controlled motivation seems be put them at greater risk.

BACKGROUND As people age, their physical capacities (eg, walking and balance) decline and the risk of falling rises. Yet, classic fall detection devices are poorly accepted by older adults. Because they often wear eyeglasses as they go about their daily activities, daily monitoring to detect and prevent falls with smart eyeglasses might be more easily accepted. OBJECTIVE On the basis of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2), this study evaluated (1) the acceptability of smart eyeglasses for the detection and prevention of falls by older adults and (2) the associations with selected fall-related functional physical capacities. METHODS A total of 142 volunteer older adults (mean age 74.9 years, SD 6.5 years) completed the UTAUT2 questionnaire adapted for smart eyeglasses and then performed several physical tests: a unipodal balance test with eyes open and closed, a 10-m walk test, and a 6-minute walk test. An unsupervised analysis classified the participants into physical performance groups. Multivariate ANOVAs were performed to identify differences in acceptability constructs according to the performance group. RESULTS The UTAUT2 questionnaire adapted for eyeglasses presented good psychometric properties. Performance expectancy (β=.21, P=.005), social influence (β=.18, P=.007), facilitating conditions (β=.17, P=.04), and habit (β=.40, PR²=0.73). The unsupervised analysis based on fall-related functional physical capacities created 3 groups of physical performance: low, intermediate, and high. Effort expectancy in the low performance group (mean 3.99, SD 1.46) was lower than that in the other 2 groups (ie, intermediate: mean 4.68, SD 1.23; high: mean 5.09, SD 1.41). Facilitating conditions in the high performance group (mean 5.39, SD 1.39) were higher than those in the other 2 groups (ie, low: mean 4.31, SD 1.68; intermediate: mean 4.66, SD 1.51). CONCLUSIONS To our knowledge, this study is the first to examine the acceptability of smart eyeglasses in the context of fall detection and prevention in older adults and to associate acceptability with fall-related functional physical capacities. The older adults with higher physical performances, and possibly lower risks of falling, reported greater acceptability of smart eyeglasses for fall prevention and detection than their counterparts exhibiting low physical performances.
