This work was carried out with 40 endurance athletes distributed in three experimental
groups, who respectively consumed virgin olive oil, refined olive oil and sunflower oil as main
dietetic fat for 40 days, decreasing the total intake of saturated fat in all of them. They
performed a maximal exercise test before and after the period of adaptation to the diet they
followed, getting samples of blood before, at the end and half an hour after the test. The
previus results seem to show a statistically significant increase of VO2max after the 40
experimental days. This VO2max does not correlate to the duration of the daily training of
each athlete, which suggests an influence of this dietetic manipulation. Finally, the results of
biochemical parameters show a beneficial effect on health of the diet-sport relationship and an
improvement in the endurance capacity as a consequence of higher tolerance to lactate in the
virgin olive group.
