Aikido practice is called 'Keiko' in Japanese.

Aikido differs from sport in the sense that it's goal is not to win. Winning is only relative.
The purpose of Aikido is, by training and purifying body, mind and spirit, to make a man sincere and physically and mentally strong.
Aikido is not to correct others; it is for correcting your own mind.
If studied in this peacefull way, Aikido can be usefull, to anybody, anywhere and at anytime in our daily lifes.
But in the end it is like O'Sensei said:

"True Budo cannot be described by words. Only practicing the Art can unveil it's beautifull secrets, and manifest what's in the Heart."
