Our research focuses on the question of the mechanisms by which acute and chronic mental stress has a negative impact on health.

  • MODSTR: Modification of Biological Stress Response Patterns through Experimental Manipulation of Cognitive Coping Strategies

    (Third Party Funds Single)

    Term: since 1. April 2022

    Changes in response patterns of biological stress systems, including responses of the sympathetic nervous system (SNS) and the hypothalamus-pituitary-adrenal (HPA) axis to repeated stress, can promote the development and progression of chronic inflammatory diseases via changes in downstream inflammatory processes. The aim of the proposed project is thus to investigate, whether habituation of biological stress system activity including responses of the inflammatory system can be modified. Aiming to test for possible paths of action, a randomized-controlled study with two intervention programs designed to manipulate cognitive coping strategies will be carried out. By increasing either ruminative or self-compassionate thoughts among healthy young adults, the intervention programs are expected to affect the regulation of occurring emotions as well as the reactivity of biological systems during repeated stress exposure. The results should provide insight into whether modifying response patterns of biological stress systems could reverse a significant biological mechanism in the development of stress-related diseases.

  • FEARFALL: Chronic stress level and functional health in older adults: the impact and role of fear of falling

    Maintenance of physical function, mobility and ability to live independently are important goals for older persons. However, this is counteracted by age-related loss of muscle mass, strength and function. Furthermore, this degenerating process can be reinforced if the older person avoids physical activity and exercise due to fear of falling. We established that fall-related psychological concerns (FrPC) are not only leading to decreased physical activity, but are also associated with elevated levels of inflammation. Consistent with that, long-term exposure to adverse psychological conditions, including chronic stress and anxiety, have been linked to the upregulation of inflammatory activity. This chronic low-grade activation of the immune system was shown to intensify the decay of skeletal muscle. Therefore, a vicious, feed-forward cycle of fear of falling, inflammation, loss of muscle mass and decreasing physical function is created that ultimately results in negative health outcomes, i.e. falls, dependence and death. Exercise training alone is not likely to interrupt this cycle, because a person with elevated FrPC would experience high stress and thus more inflammatory cytokines, blunting the anabolic effects of the intervention. Therefore, the planned study will utilize a multi-component intervention with exercise training and cognitive-behavioral components to address FrPCs and oppose muscular decay. For this aim, the expertise of a psychological and a geriatric institute is necessary. The randomized controlled trial will be conducted using established effective training programs for reduction of FrPC. The intervention group will conduct at least one 60 min exercise session per week and an additional home program, while a sham control group will receive a multicomponent intervention including sham activity, cognitive training and educational health lecture at the same frequency. For the operationalization of specific FrPCs the Falls Efficacy Scale - International (FES-I) will be used. Stress and related psychological symptoms will be monitored by established self-reports and by measuring salivary cortisol. Concentrations of Creactive protein (CRP), interleukin 6 (IL-6), interleukin 10 (IL-10) and tumor-necrosis-factoralpha (TNFα), as well as gene expression of select inflammatory transcripts, will be used as surrogate parameters of the inflammatory status at baseline and at several time-points during the intervention and follow-up. This will allow us to test whether the reduction of specific FrPCs or general psychological symptoms will reverse alterations in stress systems, and / or slow down low-grade inflammation. We will measure changes in activity, as well as psychological and biological pathways leading from FrPCs to muscle loss, to disentangle the individual contribution to sarcopenia, and to provide an additional pathway to break or slow-down the vicious cycle of FrPCs and sarcopenia.
  • Berührungslose Messung von Stress, seiner Determinanten und Konsequenzen

    (Third Party Funds Group – Sub project)

    Overall project: Empathokinästhetische Sensorik
    Term: 1. July 2021 - 30. June 2025
    Funding source: DFG / Sonderforschungsbereich (SFB)
    URL: https://www.empkins.de/

    Ziel dieses Teilprojekts ist es, Stress durch empathokinästhetische Sensorik berührungslos messbar zu machen. Aufgrund der Auswirkungen auf menschliche Gesundheit und Leistungsfähigkeit hat die Erforschung von Stress eine hohe Priorität, wird jedoch durch aufwändige und meist invasive traditionelle Erfassungsmethoden erschwert. In D03 werden in laborexperimentell induzierten, akuten Stresssituationen empathokinästhetische Sensormodalitäten erforscht, die es erlauben, Stress durch berührungslose Erfassung von Makro- und Mikrobewegungen in Zusammenarbeit mit A02, A04 und A05 messbar zu machen.
