This study aimed to compare changes in genes expression associated with inflammation and apoptosis in response to heat stress caused by sauna between people with varying cardiorespiratory fitness levels. We hypothesis that high cardiorespiratory level caused higher positive changes after four weeks of sauna bathing. Blood samples were taken at rest before and after the first and last sauna sessions and 48 hours after the last sauna session and used to assay HSP70 (HSPA1A), HSP27 (HSPB1), interleukin 6 (IL6), and interleukin 10 (IL10) genes expression in blood with quantitative real-time qRT-PCR. Overall, small decreases in rest values of HSPA1A and IL6 mRNA, increase in HSPB1 mRNA, and a significant increase in IL10 mRNA were observed after four weeks of exposure to heat stress. Our findings suggest that an adaptive response to heat stress (an anti-inflammatory response) occurs faster in people with higher cardiorespiratory fitness.
Background: During the last several years, diametrical difference in attitude to physical activity in youth has been noticed. Engagement in any form of physical activity always goes together with motivation for its undertaking, most often connected with realization of personal expectations. Its sources are perceived, among others, in interior factors, such as: joy resulting from participation in physical activity itself, personal achievements, and pleasure of finding release in movement or social contacts, e.g. spending time with friends. The present paper attempts to assess the motivation for additional physical activity undertaken by first-year students of the Faculty of Physical Education at the Gdansk University of Physical Education and Sport in 2000 and 2010 in their free time. Material/Methods: The research involved first-year students studying at the Faculty of Physical Education at the Gdansk University of Physical Education and Sport in the years 2000 and 2010. Generally, 639 students (42% women and 58% men) were examined. The research was conducted by means of a diagnostic poll with the use of authors' own questionnaire. Results: The students from 2000 differed in a statistically significant way in taking care of their health, looks and figure and they were enjoying physical activity more. Important statistical differences were noted in undertaking physical activity in order to socialize in the following time points of the research. Both groups of students from 2000 and 2010, quoted a lack of financial means as the main reason limiting their physical activity. Conclusions: The research indicates the difference in motivation for physical activity between firstyear students in 2000 and 2010.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
