Speed training and real endurance/ "put the sword to the heart"

Today I did 1 h run- speed training. Several intervalls (2-4 mins running at high speed at around 4:10 - 4:30 min/km. I found some nice hints at: "Running even faster".

Than I did some research about the chinese character for endurance. I qoute: A brief discussion of the chinese character Ren: "The character "Ren" (忍, forbearance) is composed of the element "xin" (心, heart) which represents the meaning, and the element "ren" (刃, knife blade) which represents the sound. "Ren" means to endure, to forbear, and to tolerate. It also contains the connotation of self-restraint and self-control. The character "Ren" (forbearance) is formed by placing the "knife" over the "heart," as if implying "Ren" (forbearance) is not easily achieved by ordinary people, but requires a higher level of cultivation, discipline, and will."

At last I researched about better and more effective training. I ended up with detailed body-mechanisms and movements. One website stated: a better training can be accomplished by a closer look at correct body movement during excercises. The need of a trainer becomes more and more evident to get it right. Correct movement one can accomplish by: theatre, dancing, or tai chi classes. Tai Chi might be a real important way to maintain the energy during a competition. I found several swim (total immersion), bike, running and breathing methods focusing on "core strength". Trying to move more efficient is very close to the idea of tai chi. There are even "mental strengthening" elements in both concepts. Further investigation will be done. http://www.willamette.edu/~jlaronge/principles.html
