NCT ID: NCT06288828 Not yet recruiting - Physical Activity Clinical Trials

The Efficacy of Aerobic Exercise Training on Autonomic Nervous System and Endothelial Function in Patients With Compensated Cirrhosis

Start date: March 5, 2024
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to explore the impact of a 16-week aerobic exercise regimen on the autonomic nervous system and endothelial function in patients with compensated cirrhosis who maintain sedentary lifestyles. The primary research question is: 1) What effect does 16 weeks of aerobic exercise have on changes in the autonomic nervous system and endothelial function in cirrhotic patients? Additionally, the secondary research questions are: 1. How does a 16-week aerobic exercise program influence changes in muscle mass, muscle strength, and physical performance in cirrhotic patients? 2. Is there a correlation between muscle mass and parameters of the autonomic nervous system in cirrhotic patients? Participants in the intervention group will undergo 150 minutes of moderate aerobic exercise per week for 16 weeks, accompanied by a personalized nutritional plan (1.2 grams of protein per kilogram of ideal body weight per day and a calorie intake of 35 kilocalories per kilogram of ideal body weight per day). The control group will solely receive nutritional guidance and maintain their sedentary lifestyle. The researchers will compare outcomes between these two groups.

NCT ID: NCT06174480 Not yet recruiting - Exercise Clinical Trials

Evaluation of the Response to Hypoxia at Rest and During Exercise in a Healthy Subject After a Cryostimulation Exposure

CRYOX
Start date: January 25, 2024
Phase: N/A
Study type: Interventional

Many information is available regarding human adaptations to cold or hypoxia. Adaptations to these environments and physical exercise constitute responses to physiological stress aimed at amplifying the organism's reactions and improving its performance. However, studies conducted so far to understand these adaptations and their underlying mechanisms have been organized in a dissociated manner, with each study focusing on only one of these specific situations (cold, hypoxia, or exercise). Understanding cross-adaptations is crucial, as human beings are often simultaneously exposed to several of these stimuli, and understanding this cross-exposure can be considered a prerequisite for pre-acclimatization strategies to these different environments. Cross-adaptations has been defined as follows: "It simply involves considering that long-term exposure (either continuous or intermittent) to a given unfavorable environment not only increases tolerance to that particular environment but also leads to gains or losses of tolerance to other unfavorable factors that the adapted organism had never encountered before." When specifically examining cross-adaptations to cold and hypoxia, only one study focusing on the human model is available. The lack of perspectives and positions regarding the results calls for further investigations. The main objective of this study is to assess the effect of repeated exposures to cryostimulation on the variation of the respiratory exchange ratio in hypoxia during exercise.

NCT ID: NCT06020313 Recruiting - Clinical trials for Cardiovascular Diseases

Autonomic and Cardiovascular Recovery After the Acute Use of Resveratrol in Overweight and Obesity Individuals

Resveratrol
Start date: August 2023
Phase: N/A
Study type: Interventional

The aim of this study is to understand the importance of resveratrol supplementation as a possible adjuvant in improving the metabolic profile and cardiovascular autonomic recovery of individuals with overweight and grade I obesity, reducing the incidence of diseases associated with obesity and the costs in primary, secondary and tertiary care.

NCT ID: NCT05807555 Recruiting - Sepsis Clinical Trials

Longitudinal Evolution of Biomarkers of Dysautonomia and Inflammation During Sepsis in Children

DysREAped
Start date: March 29, 2023
Phase:
Study type: Observational

The Autonomic Nervous System (ANS) regulates the inflammatory response in real time, just as it controls heart rate and other vital functions. Many studies have investigated induced stimulation of the vagus nerve and its therapeutic effect in inhibiting TNFα (Tumor Necrosis Factor alpha) secretion, and therefore the risk of hypotension, septic shock, organ dysfunction during inflammation. While the anti-inflammatory effect of the autonomic nervous system on inflammation has been well studied, conversely, the effect of major inflammation on the balance of the autonomic nervous system is more difficult to understand. The inflammatory reflex could be overwhelmed and the regulatory centers of the brainstem dysregulated during situations of extreme inflammation.

NCT ID: NCT05706532 Recruiting - Healthy Clinical Trials

Cardiovascular and Cerebrovascular Control in Healthy Subjects

CardioSan
Start date: May 29, 2023
Phase:
Study type: Observational

The aim of the study is to evaluate autonomic function and cerebrovascular control in 30 healthy subjects by means of noninvasive analysis of time series variability. To this extent, heart period, systolic and mean arterial blood pressure, cerebral blood velocity, peripheral resistances, respiration will be recorded from subjects during an orthostatic challenge. The interactions between autonomic cardiovascular function, cerebrovascular and peripheral control will be evaluated exploiting the most advanced signal processing techniques.

Acute Nerve Stimulation For Enhancing Human and Cognitive Performance

Start date: January 15, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to test a wearable device's effect on performance in tactical populations with a history of concussion. The main question it aims to answer is the effectiveness of the device on modulate physiological and cognitive function. The physiological function will be derived from metrics of heart rate variability and blood-based biomarkers, whilst human performance will be evaluated using tasks that assess cognitive domains of executive function, reaction time, and memory.

NCT ID: NCT05527366 Completed - Neck Pain Clinical Trials

Effect of Auricular Vagus Stimulating in Non Specific Chronic Neck Pain

Start date: August 2, 2021
Phase: N/A
Study type: Interventional

The aim of our study is to compare the efects of conventional treatment and vagus nerve stimulation on pain, normal joint movement, disability and sleep in non-specific chronic neck pain. 36 patients aged between 18 and 65 years with non-specific neck pain participated in our randomly planned study. All these patients were divided into 2 groups. Demographic and physical characteristics of the patients were recorded. The first group was treated with auricular vagus nerve stimulation. Conservatire treatment that consists of hotpack, transcutaneous electrical nerve stimulation (TENS) and therapeutic ultrasound was applied to the second group. In addition to their treatment, some home exercises were given and tought. Pain was assessed with a visual analog scale (VAS). Muscle strength was evalvated with a digital hand dynamometer. Neck normal joınt motion was evaluated with goniometer clinometer which is a mobile phone application. While disability was mensured with the neck disability index, sleep quality was evalvated with the Pittsburg sleep questionnaire. All the measurements were recorded before the trearment and after the 15 session treatment.

NCT ID: NCT05454735 Recruiting - Clinical trials for Cardiac Surgical Procedures

Glycemic Variability and Autonomic Nervous System in Cardiac Surgery Patients

CAESAR
Start date: October 10, 2022
Phase:
Study type: Observational

On-pump coronary artery bypass graft (CABG) and valve replacement surgeries are high-risk procedures. Among the risk factors for postoperative complications, perioperative hyperglycemia and blood glucose variability have been reported to be associated with increased morbidity and mortality. The treatment of hyperglycemia using intravenous insulin infusion improves the prognosis in cardiac surgery patients. However, the determinants of postoperative blood glucose variability and the mechanisms leading to its deleterious impact are unknown. Thus, to date, there is no therapeutic intervention that could effectively prevent and treat the deleterious impact of glycemic variability on postoperative outcome. The purpose of the study is to evaluate whether perioperative alteration of the autonomic nervous system and preoperative blood glucose variability could be related to perioperative glycemic variability.
