Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: To determine the acute effects of a mushroom blend vs. placebo on oxygen kinetics, aerobic power and time to fatigue in healthy adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants: Twenty-eight, healthy, active, recreationally-trained adults ages 18-35.

Procedures (methods): All subjects will report to the Applied Physiology Laboratory in Fetzer Rm 025 for phase I of the study for a total of 7 visits. A randomly selected subset of 8 participants will continue to phase II, and return to the lab for an additional 3 visits to evaluate feasibility. Visit 1 will consist of a physical, enrollment and consenting. Visits, 2, 3, and 4 will be separated by a minimum of 24 hours. During visit 2, participants will perform a maximal oxygen consumption (VO2max) test on a cycle ergometer. During visit 3 participants will be asked to complete a 6-minute oxygen kinetics test on a cycle ergometer; lactate threshold and oxygen saturation will be measured at baseline, minutes 2, 3 and 6 during the 6 min ride. During visit 4, participants will perform a 3-minute critical power (CP) test and will provide a saliva sample, to be measured for cortisol levels, immediately prior to and after the CP test. Following visit 4, participants will be randomly assigned, in a double-blind fashion, to either a placebo or mushroom blend treatment group. Participants in the placebo and treatment groups will be asked to consume 2 servings, 3 times daily for 7 days. Following supplementation, participants will return to the laboratory for visits 5-7, each of which will be separated by a minimum of 24 hours. The same protocol performed during visits 2-4 will be repeated in the same order for visits 5-7; the VO 2max test, the 6 min oxygen kinetics test, and the CP test with a pre and post saliva sample. The randomly selected subset of 8 participants will continue into phase II (n=4 for treatment; n=4 for placebo). During phase II, the 8 participants in the placebo and treatment groups will be asked to consume 2 servings, 3 times daily for 14 additional days to determine feasibility of a longer supplementation phase. Following supplementation, the same protocol performed during visits 2-4 will be repeated in the same order for visits 8-10, each of which will be separated by a minimum of 24 hours.
