Learning To Relax: The Impact Of Brief Biofeedback Training On Salivary Cortisol Reduction, Dallas N. Robinson Aug 2019

Learning To Relax: The Impact Of Brief Biofeedback Training On Salivary Cortisol Reduction, Dallas N. Robinson

MSU Graduate Theses

Chronic stress has been linked to several health related and psychological problems. There is evidence that relaxation techniques can be useful in the reduction of stress and psychological complaints. Short-term interventions like computer-based biofeedback could provide a brief and independent way to manage stress and anxiety. The purpose of this study is to examine the impact of the ALIVE biofeedback program (a relatively new software that allows individuals to play a game requiring proper smoothness of breathing and heart rate) on the stress response after the Trier Social Stress Test, a laboratory stress task shown to elicit changes in cortisol …

Yoga To Decrease The Stress Response: Gentle Yoga Encourages Faster Decline In Salivary Cortisol Concentrations Following Participation In Tsst, Tabetha Gaile Hopke

MSU Graduate Theses

Short-term, activation of the human stress response system is beneficial as it prepares the body to deal with stressors at hand (McEwen & Stellar, 1993). If this system is overactive or chronically active however, it can negatively impact health and longevity (Cohen, Janicki-Deverts, & Miller, 2007). According to a review conducted by Ross & Thomas (2010) implementation of a yoga practice has been shown to down-regulate the stress response system. The present study aimed to expand on current research involving yoga for stress reduction by exploring whether participation in gentle yoga could decrease the stress response more quickly than naturally …


Stress And Body Composition Of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Brandon Scott Tappmeyer May 2019

Stress And Body Composition Of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Brandon Scott Tappmeyer

MSU Graduate Theses

The alligator snapping turtle (Macrochelys temminckii), is a species of conservation concern that is the subject of multiple head-start and reintroduction efforts across its range. In captive propagation programs, producing offspring that are in optimal physiological condition maximizes the likelihood of success after release. The purpose of my study was to compare stress and body composition between one free-ranging reintroduced population and two captive populations. The two captive populations were both housed in southern Oklahoma, but one group was reared indoors whereas the other inhabited outdoor ponds at a national fish hatchery. I used circulating glucocorticoid (corticosterone) concentrations as an …
