Conclusion
The study demonstrates that an 8-week field-based endurance training program elicits significant improvements in cardiorespiratory fitness within a previously untrained population, relative to a non-exercise control group. Significant inter-individual variability in endurance performance gains were observed following the training program. Eighteen SNPs were significantly associated with a greater than average Cooper run test score and a significant portion of the variation in endurance performance was explained by how many of these SNPs an individual possessed (r = 0.92, R
