These training techniques, aware, etc - Tradução em português

Eu estava traduzindo um texto sobre o karate, mas "travei" nos seguintes trechos:

"These training techniques were developed through research and experience the key points are being aware of and how to control one’s center of gravity and hip and back movement". Eu não entendi o sentido da palavra "aware" na frase.

"Yahara Karate as Bujutsu has been through many a scene of bloodshed".
