Study: NCT04079010

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: BFR
Description: Blood flow restriction (BFR) training is a non-invasive technique that uses wraps, bands, or inflated blood pressure cuffs to change blood flow within targeted muscles. Occlusion pressure of the femoral artery will be determine before each training session using the Delfi Personalize Tourniquet System for Blood Flow Restriction (2.0) which has embedded ultrasound technology to continually measure the blood flow and with auto-adjust the pressure. The target percent of occlusion is 50% of total blood flow while completed a prescribed resistance training regimen 4 times per week.

Intervention: Arginine
Description: The BFR+Arg group will consume Arginine supplement daily throughout the course of the study. Supplements were manufactured by Kyowa, a US-based cGMP-compliant contract manufacturing facility independently audited and pre-qualified by the quality compliance firm, Obvium\*Q, LLC (Dallas, TX). Manufacturing batch records for production of each of the supplements were maintained by the manufacturer and finished supplements were independently assayed for identity, purity, potency, and composition using appropriate USP, AOAC, or BAM methods at the independent, analytical laboratory, Dyad Labs (Salt Lake City, UT), prior to approval for release and consumption of the supplements by participants.~Each serving of the supplements were formulated to contain 3,000 mg L-Arginine (ARG; Kyowa). Each supplement also contained the inert and non-insulinotropic excipient ingredients, microcystalline cellulose and silicon dioxide.

Intervention: Placebo Pill
Description: The CON and BFR groups will consume placebo pill daily throughout the course of the study.

Manufacturing batch records for production of each of the supplements were maintained by the manufacturer and finished supplements were independently assayed for identity, purity, potency, and composition using appropriate USP, AOAC, or BAM methods at the independent, analytical laboratory, Dyad Labs (Salt Lake City, UT), prior to approval for release and consumption of the supplements by participants.~Each serving of the supplements were formulated to contain 3,000 mg Maltodextrin placebo (PLA; MALTRIN-M100; Grain Processing Corporation; Muscantine, IA). Each supplement also contained the inert and non-insulinotropic excipient ingredients, microcystalline cellulose and silicon dioxide.
