Exercise-induced Changes in DNA-methylation

Not Applicable
Terminated
Conditions
Healthy
Registration Number
NCT01931072
Lead Sponsor
Norwegian University of Science and Technology
Brief Summary

The purpose of the study was to investigate whether regular moderate- or high-intensity interval training can change the DNA methylation in a long-lasting state, and whether these changes affect the gene expression. In addition, the investigators will determine whether the intensity of the training could be an affecting factor of the possible DNA-methylation change as well. The null hypothesis was that no such exercise-induced changes occur.

Primary Outcome Measures
NameTimeMethod
Gene Expression8 weeks
DNA-methylation8 weeks

From the skeletal muscle biopsies RNA and DNA was isolated, DNA was further bi-sulfite converted and DNA-methylation was analyzed using the Illumina HumanMethylation450 BeadChip. The RNA was further used for gene expression analyses by real-time RTqPCR.

Secondary Outcome Measures
NameTimeMethod
Maximal Aerobic Capacity8 weeks

measured on treadmill at baseline and after eight weeks, also biopsies from Vastus lateralis were sampled.
