A cross-cultural re-evaluation of the Exercise Addiction Inventory (EAI) in five countries

Research into the detrimental effects of excessive exercise has been conceptualized in a number of similar ways, including ‘exercise addiction’, ‘exercise dependence’, ‘obligatory exercising’, ‘exercise abuse’, and ‘compulsive exercise’. Among the most currently used (and psychometrically valid and reliable) instruments is the Exercise Addiction Inventory (EAI). The present study aimed to further explore the psychometric properties of the EAI by combining the datasets of a number of surveys carried out in five different countries (Denmark, Hungary, Spain, UK, and US) that have used the EAI with a total sample size of 6,031 participants. A series of multigroup confirmatory factor analyses (CFAs) were carried out examining configural invariance, metric invariance, and scalar invariance. The CFAs using the combined dataset supported the configural invariance and metric invariance but not scalar invariance. Therefore, EAI factor scores from five countries are not comparable because the use or interpretation of the scale was different in the five nations. However, the covariates of exercise addiction can be studied from a cross-cultural perspective because of the metric invariance of the scale. Gender differences among exercisers in the interpretation of the scale also emerged. The implications of the results are discussed, and it is concluded that the study’s findings will facilitate a more robust and reliable use of the EAI in future research.

Experience modulates the psychophysiological response of airborne warfighters during a tactical combat parachute jump

We aimed to analyse the effect of experience level in the psychophysiological response and specific fine motor skills of novel and expert parachute warfighters during a tactical combat parachute jump. We analysed blood oxygen saturation, heart rate, salivary cortisol, blood glucose, lactate and creatinkinase, leg strength, isometric hand-grip strength, cortical arousal, specific fine motor skills and cognitive anxiety, somatic anxiety and self-confident before and after a tactical combat parachute jump in 40 warfighters divided in two group, novel (n=17) and expert group (n=23). Novels presented a higher heart rate, lactate, cognitive anxiety, somatic anxiety and a lower self-confident than experts during the jump. We concluded that experience level has a direct effect on the psychophysiological response since novel paratroopers presented a higher psychophysiological response than compared to the expert ones, however this result neither affected the specific fine motor skills nor the muscle structure after a tactical combat parachute jump.

Relationship Between Resilience and Coping Strategies in Competitive Sport

Resilience is important in sport performers to withstand the pressure they experience. This study analyzed the relationship among resilient qualities and coping strategies in 235 Spanish athletes (126 males, 109 females; M age = 20.7 yr) who practiced different sports (79.1% team sports, 20.9% individual sports). They were evaluated at the beginning of the last competitive mesocycle and after an important competition. Coping strategies and level of resilient qualities were measured by the Coping Inventory for Competitive Sport and the Resilience Scale. There was no significant difference in resilience scores between evaluations performed during the last mesocycle or competition. A significant increase occurred in the scores for emotion-oriented and distraction-oriented coping during competition. Resilience scores correlated positively to task-oriented coping and negatively to disengagement- and distraction-oriented coping during both periods. Analysis of variance indicated that athletes with high individual resilient qualities reached higher scores in task-oriented coping, using to a lower extent disengagement- and distraction-oriented coping. Results obtained suggest that resilient characteristics may associate in athletes to the use of more potentially adaptative coping strategies.

Exercise addiction in athletes and leisure exercisers: the moderating role of passion

Background and aims Recently, empirical research has linked obsessive passion to the etiology of exercise addiction, and the conceptual reason behind the fact that the latter is more prevalent in athletes than leisure exercisers has been challenged. The aim of this study was to determine the link between exercise addiction and harmonious passion, obsessive passion, and dedication to sports, in the context of athletic levels. Method A sample comprised of low- and high-level competitive athletes and non-competitive leisure exercisers (n = 313) was examined, in a cross-sectional design, in which participants completed the Spanish validated versions of the Exercise Addiction Inventory (Sicilia, Alías-García, Ferriz, & Moreno-Murcia, 2013) and Passion Scale (Chamarro et al., 2015). Results Obsessive passion and dedication to sports emerged as strong predictors of exercise addiction. Competitive athletes scored higher than leisure exercisers on all measures. Athletes competing at low and high levels only differed in dedication to their sports from each other. Team-sports athletes reported greater harmonious and obsessive passions, and dedication to sports, but not different exercise addictions, than people taking part in individual sports. Conclusions The concept of exercise addiction is not a plain and independent construct and may not reflect a psychological dysfunction in the athletic population. Athletes could interpret exercise addiction screening-items differently from non-athletes. Athletes in team sports report greater passion and dedication than those practicing individual sports.

The role of passion in exercise addiction, exercise volume, and exercise intensity in long-term exercisers

Recent studies have shown a relationship between the risk for exercise addiction (REA) and passion. This research examined whether levels of REA, volume of exercise (in weekly hours), and self-reported exercise intensities yield differences in obsessive passion and harmonious passion among individuals with long history of exercise. Respondents (n = 360) completed the Exercise Addiction Inventory, Passion Scale, and Borg Scale (assessing their usual exercise intensity), and reported their volume of exercise (hours per week). Regression analysis demonstrated that exercise intensity, obsessive passion, and harmonious passion were significant predictors (r2 = .381, p < .001) of the REA scores with obsessive passion being the strongest predictor (r2 = .318). Exercisers classified as at REA reported higher obsessive passion, harmonious passion, and exercise intensity (p ≤ .001) than those classified as symptomatic, who in turn scored higher on these measures (p ≤ .006) than asymptomatic exercisers. Participants reporting greater volumes of exercise also scored higher on obsessive passion, harmonious passion (p < .001), exercise intensity (p = .032), and REA scores (p = .042) than individuals who exercised less. Finally, women exercising between low and high intensities exhibited greater obsessive passion, as well as harmonious passion (p ≤ .005) than men reporting similar exercise intensities. These findings support the recently reported relationship between passion and REA. They also expand the current knowledge by demonstrating that obsessive passion and harmonious passion are greater in the individuals who exercise at higher volumes and with higher intensities.

Induced beliefs about a fictive energy drink influences 200-m sprint performance

Abstract Placebo and nocebo effects occur in response to subjective expectations and their subsequent neural actions. Research shows that information shapes expectations that, consequently, influence people’s behaviour. In this study, we examined the effects of a fictive and inert green colour energy drink provided for three groups (n = 20/group) with different information. The first group was led to expect that the drink augments running performance (positive information), the second group was led to expect that the drink may or may not improve performance (partial-positive information), while the third group was told that earlier research could not demonstrate that the drink improves performance (neutral/control). At baseline, the three groups did not differ in their 200-m sprint performance (p > .05). One week later, 20-min immediately after ingesting the drink, all participants again ran 200 m. The positive information group increased its performance by 2.41 s, which was statistically significant (p < .001) and also perceived its sprint-time shorter (p < .05) than the other two groups. A better performance (0.97 s) that approached but did not reach statistical significance was also noted in the partial-positive information group, and a lesser change (0.72 s) that was statistically not significant was noted in the neutral information control group. These results reveal that drinking an inert liquid, primed with positive information, changes both the actual and the self-perceived time on a 200-m sprint. The current findings also suggest that the level of certainty of the information might be linked to the magnitude of change in performance.

Obsessive and harmonious passion in physically active Spanish and Hungarian men and women: A brief report on cultural and gender differences: CULTURAL AND GENDER DIFFERENCES IN PASSION

Increased research on passion in exercise calls for direct examination of possible moderating variables, such as culture and gender, that could influence the interpretation of the research results. This study using a nation by gender between-participants design, examined differences in obsessive- and harmonious passion in Spanish and Hungarian physically active individuals. Participants (n = 1002) completed the Passion Scale, reported their gender, age and weekly hours of physical activity. Multivariate analysis of covariance revealed that the experiencing of physical activity-related obsessive- and harmonious passion differed between the 2 countries and Hungarian women scored significantly higher on harmonious and obsessive passion than Spanish women. However, Hungarian men only scored significantly higher on obsessive passion, but not harmonious passion compared to Spanish men. These results suggest that gender and cultural differences are likely to affect the interpretation and generalisation of research on passion and exercise.

Restoration of confidence and perception of coaches following sports injury

Abstract The cognitive response is an important component of the psychological recovery from athletic injury. This study was aimed to investigate changes in the psychological readiness to return to sport among injured athletes and to assess how athletes’ confidence is perceived by their coaches. Participants were 13 athletes, aged between 15 and 34 years (M = 20.7, SD = 6.0) who practiced team sports. All participants completed the Spanish version of the Injury-Psychological Readiness to Return to Sport Scale (I-PRRS) at four time intervals during the injury recovery process. Coaches responded the I-PPRS before returning to competition and after competing again. Results showed that the athletes’ confidence was lower immediately after suffering the injury and increased significantly before practice, before competition and after competition. Athletes’ perceptions of confidence before and after competition did not significantly differ from perceptions of their coaches. The findings indicate that coaches are aware of the confidence levels of athletes recovering from injury.
