Effects of Oxygen Prebreathing on Bubble Formation, Flow-Mediated Dilatation, and Psychomotor Performance during Trimix Dives. Sports (Basel) 2024; 12:35. [PMID: 38275984 PMCID: PMC10820603 DOI: 10.3390/sports12010035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/16/2024] [Accepted: 01/19/2024] [Indexed: 01/27/2024] Open
Abstract
Introduction: This research was performed to examine the effects of air and oxygen prebreathing on bubble formation, flow-mediated dilatation, and psychomotor performance after scuba dives. Methods: Twelve scuba divers performed two dives using a gas mixture of oxygen, nitrogen, and helium (trimix). In a randomized protocol, they breathed air or oxygen 30 min before the trimix dives. Venous bubble formation, flow-mediated dilatation, and psychomotor performance were evaluated. The participants solved three psychomotor tests: determining the position of a light signal, coordination of complex psychomotor activity, and simple arithmetic operations. The total test solving time, minimum single-task solving time, and median solving time were analyzed. Results: The bubble grade was decreased in the oxygen prebreathing protocol in comparison to the air prebreathing protocol (1.5 vs. 2, p < 0.001). The total test solving times after the dives, in tests of complex psychomotor coordination and simple arithmetic operations, were shorter in the oxygen prebreathing protocol (25 (21-28) vs. 31 (26-35) and 87 (82-108) vs. 106 (90-122) s, p = 0.028). Conclusions: In the oxygen prebreathing protocol, the bubble grade was significantly reduced with no change in flow-mediated dilatation after the dives, indicating a beneficial role for endothelial function. The post-dive psychomotor speed was faster in the oxygen prebreathing protocol.

Blue prescription: A pilot study of health benefits for oncological patients of a short program of activities involving the sea. Heliyon 2023; 9:e17713. [PMID: 37483694 PMCID: PMC10362171 DOI: 10.1016/j.heliyon.2023.e17713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 06/12/2023] [Accepted: 06/26/2023] [Indexed: 07/25/2023] Open
Abstract
Performing outdoor activities in blue spaces can help improve human health and mental well-being by reducing stress and promoting social relationships. The number of people surviving cancer has increased globally to experience this disease as a life-changing and chronic condition with physical and psychosocial symptoms that have negative impacts on their quality of life. While there has been a growth of programs in green spaces to meet the needs of cancer patients, such as follow-up post-treatment care, support groups and physical activity programs, very few studies have examined the effects of activities involving the sea for the health and well-being of oncology patients. This is the first study to evaluate whether different outdoor activities in blue spaces can benefit oncological patients' physical and mental health using smartwatches, sphygmomanometers and Profile of Mood States (POMS) questionnaires. We assessed changes in blood pressure, heart rate, sleep quality and mental health of 16 patients after twelve sessions of three different activities (walking, beach and snorkelling) and four sessions of a control activity. While no significant differences between activities were observed in terms of the data gathered by the smartwatches, a gradient of positive results for human mental health was observed towards exposure to a blue space, assessed through POMS questionnaires. Results show that exposure to blue spaces contributes to tension and anger reduction and improves the vigour mood state of oncology patients. No significant increases in patients' heart rate were recorded after the beach and snorkelling activities, with results similar to the control activity, suggesting that the contribution may be to participants' relaxation.

Abstract
The aim of this study was to assess the wellbeing of 248 young Polish adults between 18 and 26 years old (M = 22.35; SD = 2.20) involved in adventure blue space recreational activities. The adventure water recreational activities were measured by using a questionnaire specially designed for the purpose of this study. This questionnaire consisted of two subscales: adventure recreation associated with water risks and adventure recreation associated with weather risks. In turn, wellbeing was measured using six scales loaded in two factors: hedonic wellbeing and eudaimonic wellbeing. The regression analysis indicated that wellbeing (hedonic and eudaimonic) was positively predicted by adventure recreation associated with water risks. In turn, eudaimonic wellbeing was negatively predicted by adventure recreation associated with weather risks. Additionally, the cluster analysis revealed three distinct clusters of recreationists characterized by diverse results on the scales of adventure recreation dealing with water and weather risks: soft adventurers (low water risks/high weather risks), hard adventurers (high water risks/high water risks) and avoiders (low water risks/low weather risks). The hard adventurers had significantly higher means on hedonic wellbeing than that of the soft adventurers and the avoiders. Surprisingly, the soft adventurers had a significantly lower mean on eudaimonic wellbeing than that of the group of hard adventurers and the group avoiding risky activity in an aquatic environment.

Effects of the COVID-19 pandemic on SCUBA diving experience in marine protected areas. JOURNAL OF OUTDOOR RECREATION AND TOURISM 2022. [PMID: 37521255 PMCID: PMC8890976 DOI: 10.1016/j.jort.2022.100501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/28/2022]
Abstract
Faced with the need for isolation of most people to reduce the transmission of COVID-19, a great concern for the well-being of the population has resurfaced. Considering the numerous benefits of outdoor activities to human health and well-being, we assessed whether the quality of the experience of recreational divers in a marine protected area (MPA) was impacted during the pandemic. We applied a semi-structured questionnaire to divers, collected their socioeconomic profile, preferences, motivations, experiences, and compared the results with those obtained in the previous season. We found that the quality of the recreational diver's experience remained high even during one of the world's biggest health crises. This suggests that the combination of contact with a preserved environment and the adaptation of regulations in favor of visitor safety was enough to stimulate positive experiences. Therefore, we highlight the importance of investing in adaptive management so that MPAs continue to promote ecosystem services such as human health and subjective well-being. Management implications •Quality of experience for recreational divers remained high and was unaffected after the first major wave of COVID-19 cases.•Through adaptive tourism management, MPAs can promote positive experiences even in challenging contexts.•High impact of environmental attributes on the quality of divers' experience reinforces that threats to ecosystems are social impacts.•Socially unequal access to benefits generated by MPAs may negatively influence population's support for these areas.•Efforts are needed to strengthen the equity of distribution of positive social impacts in MPAs.•Potential to provide positive experiences for users must be seen beyond economic value, but as an investment in the population's subjective well-being.

Abstract
The intensive growth of cruise tourism worldwide during recent decades is leading to growing concerns over the sector's global environmental and health impacts. This review combines for the first time various sources of information to estimate the magnitude of the cruise industry's environmental and public health footprints. This research shows that cruising, despite technical advances and some surveillance programmes, remains a major source of air, water (fresh and marine) and land pollution affecting fragile habitats, areas and species, and a potential source of physical and mental human health risks. Health risks impact both the people on board (crew and passengers) and on land (workers of shipyards where cruise ships are dismantled and citizens inhabiting cities with cruise ports and shipyards). In this context, we argue that the cruise industry should be held accountable with more monitoring and regulation to prevent or minimize the growing negative environmental and human health impacts.
