There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The goal of this repeated measures study is to evaluate acute work rate adjustments during high-intensity interval training (HIIT) in a hot and temperate environment in healthy and active adults when using target heart rate to prescribe the exercise intensity. The main questions it aims to answer are: - Will HIIT based on target heart rate in a hot environment result in increased cardiovascular (i.e., elevated recovery HR) and thermal strain compared to HIIT in a temperate environment? - Will work rate be lowered to a greater extent during HIIT in a hot environment compared to a temperate environment in order to maintain target heart rate? - Will maximal aerobic capacity (V̇O2max) decrease to a greater extent after HIIT in the heat compared to a temperate environment? Procedures: Participants will complete 5 trials on a cycle ergometer. Trial 1 (Control Visit): Participants (n = 7) will have their maximal heart rate and V̇O2max measured in a temperate environment (~22 °C, 40% RH). Experimental Trials 2-5: The order of the trials will be counterbalanced and randomly assigned to participants. - 15TEMP: Participants will cycle at 70% of their maximum heart rate for 8 minutes as a warm-up, followed by one round of HIIT. The HIIT protocol consists of 4 minutes at 90% of maximum heart rate followed by 3 minutes at 70% of maximum heart rate, totaling 15 minutes, in a temperate environment (~22 °C, 40% RH). After the HIIT session, a graded exercise test will measure V̇O2max. - 15HEAT: Similar to 15TEMP, but participants will perform the HIIT protocol in a hot environment (~35 °C, 40% RH). - 43TEMP: Participants will cycle at 70% of their maximum heart rate for 8 minutes as a warm-up, followed by the HIIT protocol repeated four times (4 minutes at 90% of maximum heart rate and 3 minutes at 70% of maximum heart rate), totaling 43 minutes, in a temperate environment (~22 °C, 40% RH). - 43HEAT: Similar to 43TEMP, but participants will perform the HIIT protocol in a hot environment (~35 °C, 40% RH).
The primary objective of this study is to evaluate the effects of therapeutic and supratherapeutic doses of avacopan on the heart rate corrected QT interval, using Fridericia's formula (QTcF).
The primary objective of this clinical trial is to evaluate the effect of a high-fat, high-calorie meal on the pharmacokinetic (PK) profile of CCX168, following oral administration of a single dose of 30 mg CCX168 to healthy volunteers.
This study will evaluate the clinical efficacy, safety and the performance of the BTL-785-2 applicator of the BTL-785F system for non-invasive treatment of facial wrinkles and correcting facial skin laxity.
The investigators propose to evaluate Guardant Health's commercially available colorectal cancer screening assay(Guardant SHIELD) in individuals who are not up to date with CRC screening.
The purpose of this study us to investigate the effects of mistimed eating on blood pressure, kidney function and vascular function.
The purpose of this study is to describe the real-world use of Belantamab Mafodotin - blmf (BLENREP) and associated patterns of care, including dosing and dose modification, eye care specialist visits, associated healthcare utilization, and clinical outcomes in patients with relapsed and/or refractory multiple myeloma (RRMM) seen in the Duke Cancer Institute (DCI) clinics.
Bioequivalence Study of Tiotropium Bromide Inhalation Powder 18 μg
The purpose of this study is to find out if the FMF Connect Teacher Companion website is acceptable and usable by teachers. The FMF Connect Teacher Companion website is a website for teachers adapted from the Families Moving Forward (FMF) Program. The FMF Program is an evidence-based intervention for caregivers of children with FASD. The study will determine if the a web page intervention is feasible and acceptable by looking at enrollment and retention of study subjects and acceptability of assessments.
Researchers will investigate the correlation between a) self-reported dietary intake of foods and beverages, b) intensity of sucrose stimuli, and c) liking rating of sweet stimuli, with the relative expression of the taste receptor genes from human fungiform papillae (TAS1R2 and TAS1R3). * This research will provide new information on how sweet taste perception is regulated. - The hypothesis: Greater dietary consumption of sugar and sweet foods is associated with reduced expression of the sweet taste receptors. - The results of this study could help to identify pathways to help modify sweet taste perception by uncovering this mechanism. Participants will sample solutions prepared with sweet ingredients, provide salivary DNA, and collect fungiform papillae. This will allow researchers and investigators to compare the relationship between the sweetness of stimuli, genetic differences in sweet taste receptors, and expression levels of sweet taste receptor genes.
