ACTIVE NOT RECRUITING NA

Quantification of Progenitor Cell Circulation Following Vascular Resistance Exercise Using Delfi Tourniquet System

NCT07213726 · View on ClinicalTrials.gov ↗

Study Summary

The purpose of this observational study is to examine how slowing down blood flow to the legs- a practice called blood flow restriction (BFR)- during exercise by applying compression to the legs affects the way stem cells are released into the blood stream. This will be determined by drawing 6 cubic centimeters (ccs) of blood immediately post-exercise after the Delfi Personalized Tourniquet System (PTS) has been removed. 6 ccs of blood will also be taken prior to exercise and at the 20-, 40-, and 60-minute marks after exercise. The main question of this study is: • Will the levels of stem cells extracted before and after exercise be the same if blood flow is restricted during exercise? In this study, participants will undergo the following: * 6 ccs of blood extracted from the forearm prior to exercise to establish a baseline * 3 exercises- seated leg extension, semi-reclined leg press, and seated hamstring curl- consisting of 4 sets of 30-15-15-15 repetitions per exercise; resistance will be set to 30% of one-rep maximum (1-RM) * Additional 6 cc blood draws will be performed immediately post-exercise and after 20, 40, and 60 minutes have elapsed

What the Registry Record Tells You About NCT07213726

The ClinicalTrials.gov registry entry for NCT07213726 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 15 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Andrews Research & Education Foundation, which has 4 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.

The record links to 1 condition, with Blood Flow Restriction (BFR) Training Effects appearing as the primary indexed condition, and to 1 intervention — of which Delfi Personalized Tourniquet System is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.

Geographic footprint matters for practical reasons: NCT07213726 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
