This is the National Geographic episode that I mentioned previously.

There are some superb video scenes which help to provide another perspective of the science behind the martial arts.

Some people felt that this series lack cultural diversity as most of the weapons used in tests were from Japan, China or the Philippines. Weapons from Europe, the Middle East, Africa or the Americas were not included in the testing. Additionally the only styles from outside of Asia that were tested were Boxing, Capoeira, and Brazilian Jiujitsu (which is partially Japanese). Styles such as Sambo or Savate were not included.

What do you think?
