La planification différait selon les profils de plongée visés avec une très grande variabilité inter-individuelle. La densité des gaz en profondeur dépassait fréquemment les recommandations. Parmi les répondants, 9,8 % déclaraient avoir expérimenté des symptômes évocateurs de toxicité des gaz, principalement liée à de la narcose à l’azote. Trente-quatre pourcents ont présenté des signes évocateurs d’accident de décompression (ADD) au cours de leur pratique pour une incidence estimée à 27/10 000 plongées et 3,6 % décrivaient des difficultés respiratoires persistantes pouvant évoquer un œdème pulmonaire d’immersion. En cas d’ADD seulement 42 % recevaient de l’oxygène normobare, 35 % recherchaient un avis médical et 29 % de l’oxygénothérapie hyperbare. Trois avaient déclaré conserver des séquelles.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;La variabilité des pratiques souligne le manque de données scientifiques fortes soutenant celles-ci. L’accidentologie en plongée trimix pourrait être supérieure à la plongée loisir mais avec des tableaux le plus souvent peu sévères. Les prises en charge restent trop souvent négligées malgré le haut niveau de connaissances des plongeurs. Le pronostic semble toutefois le plus souvent favorable. Il apparaît essentiel de poursuivre les recherches sur la décompression et les effets physiologiques de ces plongées particulières. Enfin, les efforts de sensibilisation et d’éducation aux premiers soins en plongée doivent être poursuivis auprès de cette communauté exposée.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Objectives&lt;/h3&gt;&lt;div&gt;The democratization of deep technical diving beyond 50 meters was enabled by the development of rebreather and the use of helium-based breathing mixtures.

Multivariate logistic regression analysis was performed to evaluate the association, which was also analyzed by sex and age. The results showed that the more days adults with eating or depressive disorder walked, the less likely they were to suffer from symptoms. Additionally, the more severe the eating or depressive disorder symptoms, the greater the effect of walking. Thus, walking was effective in reducing the symptoms of eating and depressive disorders. For adults with sleep disorders, walking compared with not walking was more likely to cause symptoms. However, regardless of the age and sex, as the number of walking days increased, the degree of sleep disturbance decreased. Specifically, for eating disorder symptoms, adults who walked 5 or more days per week compared with those who did not walk were 0.939 (95% confidence interval [CI]: 0.912–0.968, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001), 0.755 (95% CI: 0.705–0.808, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001), and 0.667 (95% CI: 0.623–0.713, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001) less likely to suffer from eating disorder symptoms for several days, more than a week, and almost daily, respectively. For depressive disorder symptoms, adults who walked 5 or more days per week compared with those who did not walk were 0.967 (95% CI: 0.938–0.997, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.05), 0.717 (95% CI: 0.666–0.773, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001), and 0.645 (95% CI: 0.594–0.700, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001) less likely to suffer from depressive disorder symptoms for several days, more than a week, and almost daily, respectively. For sleep disorder symptoms, adults who walked 5 or more days per week compared with those who did not walk were 1126 (95% CI: 1095–1158, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001) more likely to suffer sleep disorder symptoms for several days.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;div&gt;Walking was effective for women with eating disorders and depression and for men with sleep disorders. Furthermore, the effect of walking was greater among individuals aged 65 years or older, as they were less likely to suffer from eating, depressive, and sleep disorder symptoms than those observed among individuals aged 19–44 and 45–64 years. The results of this study serve as foundational data for the development and implementation of walking programs that improve the quality of life of people suffering from eating, depressive, and sleep disorder symptoms.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Objectifs&lt;/h3&gt;&lt;div&gt;Cette étude a examiné l’association entre le nombre de jours de marche et la fréquence des symptômes de troubles de l’alimentation, de dépression et de troubles du sommeil.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Matériels et métho","PeriodicalId":21728,"journal":{"name":"Science & Sports","volume":"40 1","pages":"Pages 35-44"},"PeriodicalIF":0.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
