Healthy Paid Clinical Trials in Oklahoma

the purpose of this experiment is to determine if acute melatonin supplementation alters central and peripheral cardiovascular responses to a cold pressor test at rest and during dynamic exercise. Read Less

The goal of this work is to address increasing concerns about young children's digital media exposure and language outcomes by testing how the times course of word learning unfolds in digital environments and the cascading impact of digital media on vocabulary outcomes. The findings will have important implications for understanding when and where optimal word learning from media can occur. Read Less

The goal of this clinical trial is to learn about, test, and compare health outcomes of high vs. low-processed feeding. The main question[s] it aims to answer are: • Does consuming a diet rich in unprocessed food improve various health outcomes? Participants will either be instructed to consume a diet rich in unprocessed food for 6 months, or consume their typical diet for 6 months. At various points in the study there will be metabolic health data collected. If there is a comparison group: Researchers will compare the low-processed group to the typical diet group to see if there are improvements in metabolic health. Read Less

Most cardiometabolic diseases are characterized by increased muscle sympathetic nerve activity (MSNA) during rest and exercise which contributes to poor health outcomes. In healthy humans during muscle contraction, there is a blunting of skeletal muscle vascular responsiveness to increases in MSNA. However, the exact mechanisms involved are unknown although, best evidence suggests that the mechanism is endothelium derived, but nitric oxide (NO) and prostaglandin (PG) independent. Endothelium-derived hyperpolarizing factor (EDHF) is a NO and PG independent vasodilator in both cerebral and skeletal muscle circulations, however, it is unknown if EDHF contributes to vascular responsiveness during elevated MSNA. The application of lower body negative pressure (LBNP) is a safe and non-invasive manipulation that can be used to increase MSNA causing vasoconstriction in humans. Therefore, the purpose of this experiment is to determine if acute inhibition of EDHF alters central and peripheral vascular responses to LBNP at rest and during dynamic exercise. Thereby, providing evidence by which EDHF contributes to vascular control in healthy humans and identify it's potential as a therapeutic target for cardiometabolic diseases that are characterized by elevated MSNA Read Less

Investigators will conduct a two-group randomized waitlist-control trial to assess the efficacy of the Wakaya: Rising Up for Choctaw Youth Health program on improving physical activity, reducing sedentary behaviors and improving healthful eating habits as well as delaying or reducing alcohol, tobacco and other drug use. Wakaya is an experiential, outdoor, nature-based program grounded in Choctaw values. It is a multi-level intervention that increases individual motivation and leadership skills to make healthy behavioral choices for behavior and exercise. Read Less

Blood flow restriction associated with resistance training is suggested to potentiate increases in muscular strength and hypertrophy. This study will compare the effects of resistance training associated with blood flow restriction with a regular resistance training program. Findings of this project will provide important information regarding a promising intervention to potentiate muscle performance. Read Less

In this project, we aim to determine any potential effects of a weak electrical current applied to the neck or thoracic area on functional capacity and muscle activation. Healthy individuals will participate in one familiarization followed by three experimental sessions. Fatigability and motor function will be assessed in each test session. Read Less
