An Association between Alexithymia and the Characteristics of Sport Practice: A Multicenter, Cross-Sectional Study

Prevalence of alexithymia and depression among professional contemporary French dancers

Background

A high incidence of mental disorders has been observed in contemporary dance, characterized by the integration of physical performances with artistic demands. The aim of this study is to evaluate the prevalence of alexithymia and anxiety in a sample of professional ballet dancers.

Methods

The participants, involved in a national contemporary dance company ("Ballet de Lorraine"), underwent a medical assessment including an exercise test and completed computerized questionnaires on anthropometric data and characteristics of sports practice (level and weekly time spent on sports practice) as well as alexithymia (TAS 20), depression (BDI-13), and anxiety traits (STAI-Y form B).

Results

A total of 22 professional dancers were included. This study revealed a prevalence of alexithymia at 9.1%. Within the same sample, the prevalence of anxiety was 9.1%, and 7 dancers showed results indicative of minor depression.

Conclusion

The prevalence of alexithymia, depression, and anxiety is lower in the population of professional contemporary dancers compared to what has been reported in the general and athletic populations. This may be attributed to the artistic intention present in contemporary dance, which might enhance emotional awareness and expression, potentially acting as a protective factor against these psychological conditions. However, further studies with larger and more diverse samples are necessary to confirm these findings and to explore the underlying mechanisms.

A comparison of the acute effects of high intensity interval training and moderate intensity continuous training on working memory and emotional state in adolescent women with subthreshold depression

Objective

Various guidelines emphasize the cognitive and emotional benefits of physical activity. However, it is not yet clear what kind of exercise intensity is suitable for individuals with subthreshold depression. Therefore, this study aims to examine the effects of high intensity interval training (HIIT) and moderate intensity continuous training (MICT) on the working memory and emotional state.

Methods

Forty-nine female students with subthreshold depression (mean age 16.3 ± 0.5 yrs) completed 20-min group of sit (SIT), MICT, and HIIT on separate days in a counterbalanced order. The modified n-back task was employed to evaluate working memory. Emotional state was assessed using the Feeling Scale (FS) and Felt Arousal Scale (FAS).

Results

Regarding working memory, for accuracy, SIT (82.41 ± 13.79%), MICT (81.79 ± 13.19%) and HIIT (82.06 ± 11.36%) have no significant difference (all p > 0.05). However, for reaction time, MICT (459.86 ± 131.47 ms) is significantly faster than HIIT (491.16 ± 115.68 ms) (p = 0.046), and there is no significant difference between MICT and SIT (462.71 ± 120.64 ms) (p > 0.05). Concerning emotional state, for arousal, FAS scores significantly increased after both HIIT (2.39 ± 1.30 to 3.76 ± 1.12, p < 0.001) and MICT (2.55 ± 0.88 to 3.94 ± 1.08, p < 0.001) compared to pre-exercise, and the increase caused by them was significantly higher than that of SIT (HIIT: p = 0.011; MICT: p < 0.01). For pleasure, the increase in FS score after MICT (-0.27 ± 1.13 to 1.06 ± 1.79) was significantly higher than that of SIT (0.32 ± 1.38 to 0.58 ± 1.53) (p < 0.01).

Conclusion

Acute MICT can enhance working memory and improve the emotional state of adolescent women with subthreshold depression, while HIIT may decrease working memory and pleasure in this particular population.

Disentangling general and sport-specific risk factors for anxiety and depression in a mixed sample of athletes and non-athletes

The present study was designed to assess whether competitive athletes and non-athletes differ in terms of certain personality traits linked to atypicalities in emotion awareness and regulation, and whether being an athlete accounts for unique variance in symptoms of anxiety and depression when these traits and exposure to childhood emotional abuse are held constant. In order to address these questions, we had 483 undergraduates (Mage = 19.7 years; 75.8% female), including 228 athletes and 255 non-athletes, complete self-report measures of personality (alexithymia, sensory processing sensitivity or SPS, and anxiety sensitivity or AS), exposure to emotional abuse in childhood, pandemic-related stress, anxiety, and depression. Recreational and elite athletes scored lower on SPS and depression than non-athletes, and recreational athletes also scored lower than non-athletes on AS. However, involvement in competitive sport did not predict depression or anxiety when other variables were controlled for. Alexithymia, AS, and childhood emotional abuse predicted depression, and SPS, AS, and childhood emotional abuse predicted anxiety. The same pattern was seen in a subgroup of athletes (n = 91) who had recently been coached, except that in this subgroup exposure to emotionally abusive coaching was found to be an additional risk factor for anxiety. These findings help to disentangle general and sport-specific risk factors for anxiety and depression and may have important implications for preventing and treating these problems in athletes and non-athletes alike.

Effects of open-skill and closed-skill exercise on subthreshold depression in female adolescents: A randomized controlled trial

Background

Subthreshold depression (SD) affects a significant proportion of adolescent females, posing a risk of major depression in later life. This study examines the effects of open-skill exercise (OSE) and closed-skill exercise (CSE) on SD, executive function (EF), and emotional states in female adolescents.

Methods

A double-blind randomized controlled trial involved 95 female adolescents (mean age = 16.73 ± 0.42 years) with SD symptoms. Participants were assigned to OSE, CSE, or control (CON) groups and underwent an 8-week exercise program. Primary outcomes were assessed using the Beck Depression Inventory (BDI-13) and the Center for Epidemiological Studies Depression Scale (CES-D), with secondary outcomes including EF tasks and emotional assessments. Differences were examined using generalized linear mixed models with intention-to-treat and multiple imputation.

Results

Both OSE and CSE significantly reduced depressive symptoms, with CSE showing greater improvement. EF assessments showed enhanced cognitive flexibility and working memory in both exercise groups at 4 weeks, and superior inhibitory control and cognitive flexibility in the CSE group at 8 weeks. Emotional assessments indicated a notable reduction in negative emotions in the CSE group after 8 weeks.

Conclusions

Both OSE and CSE reduce SD symptoms in female adolescents, with CSE providing more sustained benefits for EF and emotional states. Further research on exercise interventions for mental health is warranted.Trial registration number: ChiCTR2400081139.

Boosting effect of regular sport practice in young adults: Preliminary results on cognitive and emotional abilities

Several studies have shown that physical exercise (PE) improves behavior and cognitive functioning, reducing the risk of various neurological diseases, protecting the brain from the detrimental effects of aging, facilitating body recovery after injuries, and enhancing self-efficacy and self-esteem. Emotion processing and regulation abilities are also widely acknowledged to be key to success in sports. In this study, we aim to prove that regular participation in sports enhances cognitive and emotional functioning in healthy individuals. A sample of 60 students (mean age = 22.12; SD = 2.40; M = 30), divided into sportive and sedentary, were subjected to a neuropsychological tests battery to assess their overall cognitive abilities (Raven's Advanced Progressive Matrices, APM), verbal and graphic fluency (Word Fluency Task and modified Five Point Test, m-FPT), as well as their emotional awareness skills (Toronto Alexithymia Scale, TAS-20). Our results showed that sportive students performed better than sedentary ones in all cognitive tasks. Regarding emotional processing abilities, significant differences were found in the TAS-20 total score as well as in the Difficulty Describing Feelings (DDF) subscale and the Difficulty Identifying Feeling (DIF) subscale. Lastly, gender differences were found in the External-Oriented Thinking (EOT) subscale. Overall, our findings evidence that PE has positive effects on cognitive functioning and emotion regulation, suggesting how sports practice can promote mental health and wellbeing.

Occurrence of Alexithymia and Its Association with Sports Practice from a Sample of University Students: Results from a French Cross-Sectional Study

Background: This study aimed to assess the prevalence of alexithymia in a sample of university students and to determine its association with specific sports practice characteristics (competition and training). Methods: In this cross-sectional study, anthropometric data and characteristics of sport practice were collected, as well as level of alexithymia (Toronto Alexithymia Scale, (TAS-20)). Results: The study included 253 French university students who completed a questionnaire specifying their regular sports practice and level of alexithymia (TAS-20). We found 76 subjects (30%) who had proven alexithymia and 92 (36.4%) who were borderline alexithymic. A significant positive relationship between alexithymia and the weekly amount of training practice was observed. It should be noted that students who engage in more than 5 h of physical activity are more prone to be borderline or alexithymic (respectively, 19.6 and 19.7% versus 7.1% for non-alexithymics; p = 0.03). Conclusion: With a 30% frequency, alexithymia is more prevalent in this context than in the general population. Furthermore, alexithymia and borderline alexithymia are most favorably associated with higher physical activity (over 5 h per week).
