Effects of PrimaVie and Exercise Training on Human Skeletal Muscle (PrimaVie)

PrimaVie (Natreon Inc), is a a purified and standardized shilajit extract for nutraceutical use. Research indicates that PrimaVie® has targeted action for increasing energy, revitalization and anti-aging. Findings on a recent murine study revealed that PrimaVie (PV) significantly changed the expression of genes related to muscle function (unpublished data). Based on these facts, it was thought of interest to study the effect of PrimaVie and exercise training on human skeletal muscle adaptation. The objective of the study is to determine effect of PrimaVie supplementation and combined PrimaVie supplementation and exercise on changes in muscle gene expression related to muscle function. Two hypothesizes have been made, oral supplementation of PrimaVie twice a day for 12 weeks will influence gene expression in the skeletal muscle of pre-obese to obese humans, oral supplementation of PV will act with treadmill exercise training to favorably impact skeletal muscle gene expression. The participants will have a total of 3 visits over 12 weeks. During each visit will include measurement of height, weight and vital signs, 2 tablespoons of blood will be draw from left or right arm, and muscle biopsies (using biopsy needle) will be collected under the use of local anesthetics. The blood and muscle biopsies will be used for all lab related procedure.
