Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …

A positive and significant correlation was seen between self-determination and the reasons for exercise, with self-determination predicting 22% by enjoyment and 8% by fitness/health reasons. Similarly, the multivariate analysis showed that the women had more self-determination than the men and that they also rated fitness/health, social, enjoyment, …

The Need For Advanced Cardiac Life Support Certification For Open-Water Lifeguards At Huntington Beach, Ca, Daniel Jerome, Peter R. Chambers, Steve Reuter, John Porcari

International Journal of Aquatic Research and Education

The number of people visiting U.S. beaches increased in 2007 to more than 240 million people. This increase in activities does not come without danger. Lifeguards maintain beach safety, but little research is available to assist us in determining appropriate certification levels for lifeguards. The authors analyzed various injuries that occurred in the open-water environment of Huntington Beach, CA. Based on the nature of the injuries, they attempted to determine the level of training lifeguards needed. The vast majority of injuries (99%) were soft-tissue injuries, musculoskeletal injuries, or environmental injuries. It was felt that lifeguards with first-aid and basic-life-support (BLS) …

Handling Immediate Medical Care At Aquatic Facilities: Do We Need Different Levels Of Lifeguard Certification?, Leland Yarger

International Journal of Aquatic Research and Education

The first-responder and professional-rescuer training materials and training programs consider lifeguards to be first responders in emergencies (Aehlert, 2005; American Red Cross, 2001). This article asks readers to consider whether our agency lifeguard-training programs reflect a philosophy that truly view and prepare lifeguards as first responders. If not, I challenge readers to consider whether we should alter our hiring, staffing, and in-service training procedures at aquatic facilities based on the scope and need for providing adequate emergency care at those facilities.

The Relationship Between High Sensitivity C-Reactive Protein, Metabolic Syndrome And Exercise, Micheline A. Vargas

Loma Linda University Electronic Theses, Dissertations & Projects

Background: It is well known that regular physical activity is associated with lower risk of chronic diseases such as diabetes and cardiovascular disease. Physical activity is also considered an important determinant of metabolic syndrome. All levels of metabolic syndrome, diabetes, and cardiovascular disease are thought to involve inflammation. Physical activity may reduce risk, at least in part, by modifying the inflammatory process. Recent studies have demonstrated an inverse relationship between inflammatory markers, such as high sensitivity C-reactive protein (hs-CRP), and physical activity. Elevated hs-CRP appears to be an independent predictor of both CVD and diabetes. Recent evidence also suggests that …
