Fifty-five gynecological cancer survivors were assigned to either the control group (CG, n=28) or phytoncide group (PTG, n=27). The PTG meditated by lying down in a space scented with phytoncide for 1 hr a day, 5 days a week for 8 weeks. Stress levels in both groups were high prior to the experiment and decreased by 9.31%±45.98% (<i>P</i>=0.003) only in the PTG after the experiment. Although the parasympathetic nerve activity of the PTG increased, the epinephrine and cortisol levels were significantly (<i>P</i><0.001) decreased by 5.29%±25.5% and by 24.94%±11.62%. Moreover, the PTG showed a significant increase in the levels of NK cell subsets after 8 weeks, whereas there was no improvement in the CG. In conclusion, phytoncide fragrance reduces stress, increases the number of NK cells and their family even in a nonforest environment, and improves innate immunocytes in gynecological cancer survivors; parasympathetic nerve activity and cortisol hormones play critical roles in this process. That is, a phytoncide essential oil helps to stimulate changes in immunocytes' mobility by affecting the human nervous and endocrine systems, thereby providing relief for psychological stress among cancer survivors who previously had cancer cells.</p>","PeriodicalId":15771,"journal":{"name":"Journal of Exercise Rehabilitation","volume":"19 3","pages":"170-180"},"PeriodicalIF":1.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/2a/bb/jer-19-3-170.PMC10331144.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10191719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 17 healthy subjects (12 males and 5 females) participated in this study. The TT was applied, which consisted of 3-stages difficulties demanding respiratory load while they performed the cardiopulmonary exercise testing on treadmill. In each of the TT stages, ergospirometric and psychophysiologic response marker were collected such as heart rate, oxygen consumption, respiratory exchange ratio, minute ventilation, carbon dioxide output, tidal volume, respiratory rate, and rating of perceived exertion of breathing. Statistical analyses revealed a significant difference of all dependent variables in each of three TT stages, comparing with the resting phase before the TT. The TT showed strong correlation coefficient with all variables except for rating of perceived exertion during the resting phase before the TT. According to increase of exercise intensity, all dependent variables showed a linear tendency with the stages of the TT. Our findings indicated that each of the TT stages was strongly correlated with ergospirometric variables as well as psychophysiologic response during cardiopulmonary exercise testing on treadmill.

Three sessions/week for 10 weeks (total of 30 sessions) were performed; one session of IT was for 60 min.

The 10-week training reduced serum muscle damage indicators in middle-distance runners, but only the HIIT group displayed a decrease in creatine kinase.

Modern society has recently entered an era of technological revolution, and metaverse technology is playing a pivotal role. Metaverse is a compound word of ‘meta,’ a prefix meaning ‘going over,’ and ‘universe.’ Although the metaverse does not yet exist in its entirety, metaverse-like features can be found on various platforms that use the virtual world concept. In our society, the death rate of the elderly and the disabled is decreasing, and life expectancy is increasing due to the development of medical technology. Due to this, there will be more people living with various disabilities or inconveniences in the future, and a time may come when young people will be burdened as caregivers. To prepare for this future, rehabilitation exercises and rehabilitation medicine using the metaverse must be developed. ‘Care robots’ that are recently being developed are good examples. Exercise rehabilitation refers to restoring physical, mental, and social health through human movement to help the elderly and the physically challenged live independent lives. Exercise rehabilitation includes the concept of holistic health service that helps patients perform daily life activities and also serves as a prevention and recovery program for physical, mental, and social health. Currently, and in the future, the supply of exercise rehabilitation programs for the disabled, the elderly, and patients is insufficient compared to demand. To address this issue, virtual exercise rehabilitation programs have recently been developed for weak and injured populations. The metaverse is an interactive simulation that allows users to have experiences similar to reality in a virtual space created through computer hardware and software. Metaverse users can use sensory organs such as sight, hearing, and touch to realize movement in the virtual world. Metaverse technology for exercise rehabilitation is attracting the interest of the public as the number of users grows. Furthermore, the effectiveness, efficiency, and convenience of exercise rehabilitation using the metaverse have also been reported through various studies. That is, the metaverse exercise rehabilitation program has been used to treat Parkinson’s disease (Griffin et al., 2011), traumatic brain injury (Ustinova and Perkins, 2013), arthritis (Iversen et al., 2014), Alzheimer disease (White and Moussavi, 2016), strokes (Laver et al., 2017), spinal injuries (SaadonGrosman and Arzy, 2017), and multiple sclerosis (Hsieh et al., 2020). In addition, exercise rehabilitation programs using the metaverse are being utilized and studied in fields related to various diseases. Metaverse technology has been reported to increase patient satisfaction due to its usefulness and positive user interaction. However, there are also reports that ‘presence,’ which is important in metaverse technology, does not significantly affect satisfaction.
