Filter by:Fatigue of the respiratory muscles is one of the limitations of exercise at high intensity, although the mechanisms that explain it are not yet clear. This fatigue would cause a decrease in physical performance and could limit the functional capacity of the subject. In this sense, it has been shown that specific training of respiratory muscles, especially inspiratory muscles, improves their strength and resistance both in healthy people and in people with pathologies; managing to improve the quality of life and both physical and sports performance. This study, which follows the quantitative method and proposes an analytical, experimental, longitudinal and prospective design (with the aim of conducting a randomized clinical trial), proposes an intervention based on performing a specific training of inspiratory muscles for 8 weeks, taking 30 maximum inspirations at 60% of the PIM (maximum inspiratory pressure), 2 times a day for 5 days a week; with the aim of assessing the effects on inspiratory function, cardiorespiratory fitness when performing a stress test (Harvard step test) and diaphragm thickness measured by ultrasound. 40 healthy subjects between 18 and 25 years old will be recruited and divided into two groups: an experimental group (n = 20) and a control group (n = 20).
This study evaluates the cognitive and emotional effects of probiotics in healthy elderly patients.
As previously shown, individuals who experienced COVID-19 have developed some protective immunity to reinfection. The magnitude and duration of protection from reinfection conferred by the infection may be weaker after an asymptomatic infection as it is after a symptomatic COVID-19 episode. Moreover, it is known that immunity decreases among older adults compared to younger individuals often referred to as ''immune senescence,'' and leading to a decreased efficacy of vaccination. This study raises the question of whether a single administration of BNT162b2 in participants with prior SARS-CoV-2 infection leads to sufficient and durable immune response. We propose to evaluate the level of the single BNT162b2 vaccine dose response according to the severity of the previous SARS-CoV-2 infection in young and elderly participants with the same immunogenicity analyses to assess this response in participants receiving the two-dose vaccination regimen.
The purpose of this study is to characterize the disruption of intestinal barrier as a result of indomethacin challenge in healthy volunteers using an orally administered lactulose-mannitol test.
This study will assess the systemic exposure and pharmacokinetic parameters of SP-103 topical system following one, two, or three topical system applications and compare to the pharmacokinetics of ZTlido.
The purpose of this study is to evaluate the pharmacokinetic (PK) and bioequivalence (BE) of ustekinumab administered by a single subcutaneous (SC) injection with Device 1 or Device 2 in healthy participants.
Hypoxic exposure increases right ventricular (RV) afterload by triggering pulmonary hypertension, with consequent effects on the structure and function of the RV. Improved myocardial contractility is a critical circulatory adaptation to exercise training. However, the types of exercise that enhance right cardiac mechanics during hypoxic stress have not yet been identified. This study investigated how high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) influence right cardiac mechanics during hypoxic exercise (HE).
The main aim of the present study is to investigate whether oxytocin (24IU) via different routes have divergent effects on attention control in a social-emotional saccade/antisaccade eye-tracking paradigm.
This crossover study is designed to compare the rates of gastric emptying between two diagnostic radioactive meals using the gold-standard egg-white sandwich meal and Abbott Vital®. Healthy participants will be recruited and randomly assigned into either groups of Abbott Vital® and gold-standard egg-white sandwich group. The measurements will be performed over a 4-hour period using a gamma camera, and estimated gastric emptying rates will be calculated using established algorithms.
The purpose of this dietary intervention is to study the effects of dietary fibers on the gut microbiota and use yoghurt as the carrier. Hypothesis 1: Intake of dietary fibers improves the blood lipid profile of the participants. Hypothesis 2: Intake of dietary fibers stabilizes the gut microbiome (e.g., low diversity) of the participants, improves gut health and normalizes gastrointestinal function and bowel habits.
