Sport TKD is a seperate art. To excell you have to be very athletic, boardering on almost a gymnist. Most of us are not blessed with that kind of talent or body. Understand, these people are the exception. That's why they can attain such lofted status, such as the Army team. Remember, TKD is an Olympic SPORT....
In a "commerical" school, you may not undergo the level of training as that of the elite above, but that is due to the fact that very very few can attain that level. If someone should have that ability, they will surely be asked to step up to an Olympic style training camp. But the TKD training that someone receives in the normal commerical school (if it's not a total MacDojo), is more than adequate. It's up to the individual to push him/her self to attain a level of greater proficiency. I like to use this annology. College graduation - Mr. A has a 4.0 in engineering. Mr.B has a 2.8 in same. When it comes to practical application, many times it's Mr. B who excells. Same can hold true for the martial arts. We have fostered the concept within the martial arts world, that only focuses on staged combat - sport, K1, etc. We have lost site of what real training is there for, self protection. You don't have to be an Olympic medalist or caged fighter to overcome the bad guy.
Now for those that feel that what/how they are training is somewhat lacking, I would suggest that you combine Hapkido / JuJitsu to your background. Some TKD schools with ties to older masters incorporate Hapkido self defense techniques. They intertwine with each other most readily.
If you question your training and abilities, that's good in one respect. You are seeking to better yourself. That's one of the things that makes life worth living. Just don't focus on the wrong aspects of athleticism. It's one thing to do a 360 jump spinning hook kick over a table. It's quite another thing to blow somebodies knee out and put an elbow upside their head, without leaving the ground.
