Vastus lateralis muscle biopsy: post-expedition vs. pre-expedition

To define the skeletal muscle adaptations induced by exercise performed at high altitude hypoxia, we investigated if the gene expression profile of Vastus lateralis muscle was affected by 5000 m-above-sl-expedition. Two-condition experiment, Vastus lateralis muscle biopsy post-expedition vs Vastus lateralis muscle biopsy pre-expedition. Five volunteers/climbers. Biological replicates: 1 pre-expedition sample, 1 post-expedition sample.
