What This Study Did, in Plain Language
What Was Tested
Researchers studied Copper (Supplement) in this randomized controlled trial publication.
The purpose of this study was to investigate the effects of 8-week endurance training plus RC supplementation on body composition, oxidative stress, and metabolic biomarkers in young sedentary adults.
Why It Was Studied
Rhodiola crenulata (R) and Cordyceps sinensis (C) are commonly used herbs that promote health in traditional Chinese medicine.
Who Took Part
PubMed indexes the participants as young adults, both men and women.
Fourteen young sedentary adults (8M/6F) participated in this double-blind randomized controlled study.
How the Study Was Run
The design is described as randomized, double-blind and placebo-controlled.
Because people in this Copper (Supplement) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.
As a double-blind Copper (Supplement) study, the assignments were hidden from both participants and investigators until the end.
A placebo (an inactive look-alike) gave the Copper (Supplement) group a baseline to be compared against.
What Was Measured
The subject headings attached to it are Biomarkers, Body Composition, Body Mass Index, Cordyceps, Dietary Supplements, Endurance Training and Oxidative Stress.
The authors tagged it with the keywords Chinese herbs, body fat mass, maximal oxygen consumption and skeletal muscle.
What This Means in Plain Language
