Mexico's record seven medals at the 2012 London Games show that its sports organizations and athletes are doing their jobs well, National Physical Education and Sports Commission chairman Bernardo de la Garza said.

"The health of Mexican sports is good and the future is promising," De la Garza told Efe shortly before the closing of the Summer Olympics Sunday.

Mexico won a gold medal, three silver medals and three bronze medals, breaking its record for Games held outside the country.

Making history is not easy and the delegation's leaders are happy even though they have not yet completed an analysis of the finals and the effectiveness of competitors, De la Garza said.

"We have to see the results of the finals. They criticize me because I never make medal predictions, but instead look at finals, but getting to that phase (of a competition) is the most important thing since that is the key to the medals," De la Garza said.

Mexico won its first-ever Olympic men's soccer gold medal on Saturday at London's Wembley Stadium, stunning Brazil 2-1 on the strength of two goals by Oribe Peralta.

The soccer victory put Mexico in 39th place in terms of Olympic medals, but sports officials were unhappy because taekwondo competitor Maria Espinoza, one of the favorites, lost her second fight even though a video replay showed an error in tallying a blow that should have put her in the final.

Espinoza ended up winning a bronze medal with her 4-2 victory Saturday over Cuba's Glenhis Hernandez in the women's heavyweight (+67 kg) division.

"Maria was not the champion even though she did not lose a fight. Her bronze medal should be another color," the National Physical Education and Sports Commission chairman said.

De la Garza, who is known in Mexico for being able to run a 10-kilometer (6.2-mile) race in less than 45 minutes and competing in triathlons, called on fans to be patient with Mexico's athletes because they are working hard and always give everything they have.

"They should be more generous with the athletes, a fan cannot call an athlete mediocre because they don't win. It's hard when your body feels like your legs won't respond, even when the heart and head tell them to do something else," De la Garza said.

Change is coming in Mexico in terms of the health of its people, De la Garza said, referring to studies that have found that Mexicans have poor diets, do not exercise and rank No. 2 on the list of the world's most obese countries.

"We're making progress on that front, mainly in the culture of competition. There are increasingly more people who are trying to do better in their age group and challenge themselves in triathlons, marathon races and at other distances," De la Garza said.

Bernardo de la Garza, who will finish his term as chairman of the National Physical Education and Sports Commission in the next few months, said he was excited about the future.

"This virtuous circle can be repeated, we can take on the challenge of doing better each time," De la Garza said.

Mexico won the 2010 Central American and Caribbean Games and took 4th place in the medals count at the 2011 Pan American Games, with more than a dozen medals won in other world competitions that are part of the Olympic cycle, marking the best performance in its history.

"This generation deserves the victories," De la Garza said. EFE
