Filter by:The aim of the study is to investigate the effects of 6- and 12- week supplementation of a bioactive whey protein concentrate drink containing dairy phospholipids on stress reactivity and recovery in healthy adults. The proposed randomised, double-blind, placebo-controlled parallel groups design methodology will assess the stress reactivity and recovery effects (both self-reported and physiological) of 40g per day of bioactive whey protein concentrate in the form of a powder that the participant will be required to mix with 350ml of water and matched placebo prior to (baseline) and after -6 week and -12 week supplementation. The trial will utilise the Multi-tasking framework (MTF) during testing visits to elicit an acute stress response within the laboratory. Self reported anxiety (STAI short-form) at multiple time points before and after the stressor will be measured as well as perceived task demand following the stressor (NASA-TLX). Physiological measurements of the stress response will also be measured through blood pressure, heart rate arability, and galvanic skin response. 150 participants will participate, aged 25-49, and self-reported as being in good health. Participants will be supplied with either the active treatment or the placebo (allocated by a randomised schedule) whilst visiting the research centre for the testing appointments, and will take treatment home to consume daily for the duration of the study. Participants will record time of taking treatment each day in a treatment diary which will be returned to the research centre, along with any unused treatment, upon completion of the study.
This clinical trial aims to investigate the effects of a 70-day consumption of cranberry juice on cognitive and motor accuracy, mental and physiological stress, and stress response in healthy men and women between the ages of 30 and 55 who engage in multitasking. The trial will utilize a randomized, double-blinded, placebo-controlled design. It is worth noting that studies have shown that over half of middle-aged Americans experience stress, which can lead to cognitive decline and depression. Previous clinical trials have indicated that consuming polyphenol-rich foods can have positive effects on cognitive function in humans. However, no study to date has examined the long-term effects of cranberry juice consumption on cognitive performance, mental stress, and stress response specifically in individuals engaged in multitasking. Based on this gap in knowledge, the investigators hypothesize the following: (1) chronic consumption of cranberry juice will improve cognitive and motor accuracy, as well as mental and psychological stress responses in young adults subjected to intense multitasking. (2) cranberry juice consumption will alleviate the negative consequences of frequent intense multitasking, such as fatigue, mood fluctuations, cognitive impairment, and memory issues. Additionally, it is expected to have a positive impact on stress biomarkers and neurotransmitter levels. By conducting this clinical trial, the investigators aim to shed light on the potential benefits of cranberry juice consumption in improving cognitive performance, mitigating mental stress, and positively influencing stress responses in individuals who engage in intense multitasking.
The goal of this research is to test whether certain areas of focus in breath meditation are connected with certain mental health outcomes. The main question to be addressed is whether attention placed on the breath in the belly versus the nostrils during meditation results in differences in subjective experience, respiration and heart rate. Participants will: - complete surveys - have heart rate and respiration measured - practice focused breathing Participants can expect the study visit to last for one hour.
We are conducting a proof-of-concept trial to study the impact of HRV-biofeedback, a mind-body technique designed to improve stress resilience, on the quality of life, mood, and clinical skin severity of patients with psoriasis.
The negative impacts on physical and psychological health brought by COVID-19 seem to perpetuate in the post-pandemic era. It is estimated that there will be an impending mental health crisis in the general population in the aftermath of the pandemic due to the delayed negative impacts of COVID-19 and the associated non-pharmaceutical public health interventions such as social distancing, quarantining, and lockdown. Smart Health, defined as the provision of medical and public healthcare services by using mobile technologies, is a cost-effective and easily operated intervention that can provide various functions and can bring significant changes in people's health behaviour, such as prompting them to adopt a physically active lifestyle. Despite the rapid growth of digital health technology, most of them were developed during pandemic with a focus on delivering non-systematic, general virtual healthcare to people. The aim of this study is 1) to develop a Health Apps for Post-Pandemic Years (HAPPY) driven by the Transactional Model of Stress and Coping Theory, and 2) to evaluate its efficacy of alleviating people's physiological and psychosocial distress during post-pandemic era. A total of 814 eligible participants, both COVID-19 victims and non-COVID-19 victims exhibiting physiological and/or psychosocial distress during post-pandemic era, will be recruited and randomized to either the experimental or the waitlist control group. The experimental group will receive a 24-week intervention combined with an 8-week regular supervision phase plus a 16-week self-help phase. Participants will receive different coping strategies, namely physical training, energy conservation techniques and mindfulness-based coping in the intervention hub at Level 2 based on participants' assessments at Level 1, and enhance self-management at Level 3. Participants' physical activity levels will be measured using commercial wearable sensors. The waitlist control group will receive materials on the promotion of physical and psychological health during waiting period and receive the same intervention as the experimental group in week 25. It is hypothesized that the experimental group will exhibit milder symptoms of physiological and psychosocial distress, and have a more positive appraisal mindset, greater self-efficacy, and more sustainable self-management ability than participants in the waitlist control group.
Increased stress levels are a significant problem for many students and represent a risk factor for impaired mental and physical health as well as academic performance. Stress levels are particularly high during the preparation phase for major exams. There is good evidence that light therapy is an effective treatment option to improve mood in affective disorders. The present study aims at investigating the psychophysiological effects of a 3-week morning bright light exposure in reducing stress and stress-related problems in students preparing for major exams.
The purpose of this study is to examine the effect of a moderately low blood sugar stress on the nervous system. The investigators hope that information obtained from completing this study will help to reveal information about how a non-psychological stress impacts the parts of the brain that react to stress and the autonomic nervous system. The autonomic nervous system is the part of the nervous system that provides the body with involuntary or automatic control of heart rate, blood pressure, and breathing.
Osteopathic manipulative treatment has been showed to reduce LOS in premature infants. Despite the clinical effectiveness, lack of data and information on the physiological underpinning effects during the treatment has been revealed. The aim of the study is to explore the immediate physiological effects of osteopathic treatment on premature infants
The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic disease Trends', an island-wide, longitudinal population cohort of 2,000 adults (30-75 years) in PR recruited with a community-wide sampling strategy, and assessed in a network of several partner clinics across the island. The study will collect comprehensive data on multiple psychosocial, dietary, and food-related factors, CVD biological markers, and medical record data, with follow-up at 2-years, and will assess variations by urban-rural area and by timing before-after Maria.
The investigators will study in the possibility of cardiovascular disease, caused by the duty loading, of physician of internal medicine. The investigators will also explore if there {dose response effect} between the duty loading and the stress response of physicians of internal medicine. Therefore, the investigators will compare the stress responses of physicians of internal medicine during with different duty loading ( non-duty day, one duty area with 3 wards, 2 duty areas with 6 wards) in a observational method. Those stress response will be measured by cardiovascular risk indicators, including blood pressure, heart rate variability, blood sampling and urine sampling.
