When I was at primary school in the second grade, I used to follow my elder sister who is five
years older than me. She loved sports and was always playing basketball and softball. She was also
a runner and was good at it. She brought home some running awards, so I was motivated and started
running, too.
I started training at school and never missed even a day. Even if it was raining, I was training. At first
I was not very good; but as the years passed, I got better and better and started to win some competitions.
Breaking records
In 1994, I won the Mexican National Championships. Later, I won fourth place in the Pan-American
games that were held in Santiago de Chile. In 1996, I broke the Mexican record; and in 1997, I won
fourth place in the Central American Games. In 1997 and 1998, I again won the Mexican National
Championships and broke the Mexican records. Now I want to improve my personal record of 19
feet, 2 inches.
Plans for the future
I'm in Houston now, training with coach Tom Tellez at the University of Houston. He is the best
coach in the world. He also trained Carl Lewis, one of the best US athletes. I have the support of my
parents who always come with me to all my meets. I think that's why I'm where I am. Next year
I have some very important competitions. One of them is in Canada in July 1999. I hope I do well.

为三尖瓣反流的峰值速度），RVSP=△P（TR）+RAP（RVSP为右心室收缩压，RAP为右心房压）。RAP可以通过三尖瓣反流的面积进行估算，如三尖瓣为轻度反流，RAP=5mmHg；三尖瓣为中度反流，RAP=10mmHg；三尖瓣为重度反流，RAP=15mmHg。
