Taekwondo vs. Tang Soo Do

Taekwondo태권도More about the art →Tang Soo Do당수도More about the art →

Quick answer

Tang soo do is the Korean reading of the characters with which karate was originally written, and from 1944–1945 it was the name of the art of the kwans Chung Do Kwan and Moo Duk Kwan, which in the mid-fifties became the basis of taekwondo. Tang soo do keeps the forms from Shotokan and deep stances, while WT taekwondo builds on kicks and full contact in protectors. Taekwondo has been Olympic since 2000, while tang soo do competes in point sparring held by individual organizations, under WTSDA rules without contact to the body.

History and relationship

Both arts grew out of the Korean kwan schools, which taught karate from 1944–1945. Tang soo do is the Korean reading of the characters 唐手道, “the way of the Tang dynasty hand”, with which karate was written before Funakoshi Gichin changed the first character in the early nineteen thirties. Taekwondo is the later common name, and some schools kept tang soo do.

  • 1944: Lee Won-guk, a student of Funakoshi, opens Chung Do Kwan in Seoul, the first kwan named Tang Soo Do.
  • 9 November 1945: Hwang Kee founds Moo Duk Kwan, at first as Hwa Soo Do. He took the forms and a large part of the philosophy from Shotokan.
  • 1955: Choi Hong Hi, then head of both Oh Do Kwan and Chung Do Kwan, promotes the name taekwondo.
  • 1959: the Korea Taekwondo Association is formed from nine kwans. Hwang Kee refused unification, and sources give the year Moo Duk Kwan left as 1958 or the mid-sixties.
  • Hwang Kee later renamed the art Soo Bahk Do, and sources give around 1957, 1960 or 1995.

Technique

Taekwondo
  • The emphasis is on kicks, including spinning ones.
  • WT bout: 1 point for a punch to the trunk, 2 for a kick to the trunk, 3 for a kick to the head, 4 for a spinning kick to the trunk, 6 for a spinning kick to the head.
  • The head may be hit with the foot only, and grabbing, holding and pushing are penalized by gam-jeom.
Tang Soo Do
  • Deep stances as in karate, active work of the hips and a wide range of kicks.
  • WTSDA 2016: of the hand techniques, only the rear-hand straight punch, the side strike and the lunge punch with the front hand score.
  • The target is the body between the waist and the neck, and contact to the head and neck is prohibited.

The pyong-an forms in tang soo do are direct and linear like the kata of Shotokan, but the individual techniques tend to be more circular, which is attributed to Korean and northern Chinese influences. WT taekwondo rates a spinning kick several times higher than a punch.

Training

We have not been able to document the training frequency or the ratio of forms to sparring in a lesson. A review in the International Journal of Morphology (2024) describes some tang soo do forms as soft, similar to kung-fu and taijiquan.

WT taekwondo keeps dan grades in the central register of the Kukkiwon and gives children under 15 the poom grade. Tang soo do grades are issued independently by Moo Duk Kwan, WTSDA and other organizations.

Physical load and risks

Taekwondo
  • Junior WT World Championships (889 athletes): 38.55 injuries per 1,000 starts.
  • Australian amateurs in competition: 59.93 per 1,000 starts.
  • In training 7.0 injuries per 1,000 hours, over 81% of injuries occur in training.
  • Most often the knee, instep and foot, and ankle.
Tang Soo Do
  • We have not found an injury study focused on tang soo do.
  • The comparison of five styles by Zetaruk et al. (British Journal of Sports Medicine, 263 participants) does not include tang soo do.
The taekwondo figures cannot be transferred to tang soo do, since both contact and equipment differ. With a health limitation, it is advisable to consult a doctor before starting.

Self-defence

Taekwondo
  • Hosinsul is part of the syllabus.
  • WT sparring at full contact with protectors, hands to the trunk only.
  • The rules exclude grabbing, holding, pushing and attacks below the waist.
Tang Soo Do
  • Ho Sin Sul in the WTSDA: 30 defenses against grabs.
  • WTSDA sparring without contact to the body, grabs, throws and sweeps are prohibited.
  • Other organizations permit light contact, including to the head, in the dan divisions.

WT taekwondo tests kicks against resistance at full contact, while tang soo do under the WTSDA tests mainly control and distance. The competition rules develop neither the clinch nor ground fighting in either art.

Practical use

Fitnesswomen around age 63: after 8 weeks improvement in the sit-and-reach test and in stance stabilityDouris et al.: 9 soo bahk do practitioners (ages 40–60) versus 9 sedentary people, body fat 18.9% versus 30.8%

Professional usewe have not found a programthe Tang Soo Do World website states that Hwang Kee taught the air force and police until 1961

The review by Berríos-Fary et al. (2024) found just two studies of recreational tang soo do practitioners and rated the evidence as insufficient. No general suitability of either art can be drawn from studies of small groups.

Switching and combining

Taekwondo
  • Kicks, forms and the gup and dan system carry over.
  • Getting used to deep stances and hip work.
  • Reducing contact: the WTSDA allows neither contact to the body nor a hit to the head.
  • Learning the forms Kee Cho, Pyung Ahn and Bassai.
Tang Soo Do
  • Kicks, forms and etiquette carry over.
  • Getting used to full contact in protectors and electronic scoring.
  • A kick to the head scores in the WT, while the fist may go to the trunk only.

On the left is the move from taekwondo to tang soo do, on the right the opposite direction. The Pyong-Ahn forms from Shotokan were introduced by Lee Won-guk in Chung Do Kwan, which later moved over to taekwondo.

Philosophy

Taekwondo
  • Five principles according to Choi Hong Hi: courtesy, integrity, perseverance, self-control, indomitable spirit.
  • A reference to the five commandments of the hwarang.
  • Since 2018 the national martial art of Korea according to the South Korean government.
Tang Soo Do
  • Moo Duk Kwan means “school of martial virtue”.
  • Hwang Kee did not want Soo Bahk Do to become a sport or a military tool, and he focused on personal growth.
  • The name refers to the Tang dynasty, as did the original writing of karate.

Taekwondo tied its philosophy to the Olympic sport, while Hwang Kee’s line rejected sport as a goal.

Forms and terminology

Tang soo do keeps the forms from Shotokan. For the midnight blue belt nine forms are required: three Kee Cho (taikyoku in Shotokan), five Pyung Ahn and Bassai. Some schools also teach Hwang Kee’s forms Yuk Ro (1947) and Chil Sung (1952).

The Kukkiwon uses eight Taegeuk forms for colored belts, which replaced the Palgwe forms in 1971, and nine forms for dan grades, the ITF 24 Chang Hon forms.

Common misconceptions

  • The story that Hwang Kee was inspired by a man defending himself with taekkyon is questioned by the Korea Taekkyon Association.
  • The claim that around 1960 almost 75% of Korean martial artists practiced tang soo do is disputed.
  • Taekwondo is not a continuation of ancient taekkyon, and the Korean taekkyon association denies a connection.
  • Despite the similar name, Soo Bahk Do is unrelated to the old subak, which is more a general term than a defined art.

In part. The name was used by the kwans Chung Do Kwan and Moo Duk Kwan from 1944–1945, and in the mid-fifties tang soo do became the basis of taekwondo. Chung Do Kwan accepted the new name, while Moo Duk Kwan under Hwang Kee gave up on unification.

Is tang soo do Korean karate?

Which of them is Olympic?

WT taekwondo has been a medal sport since 2000. Tang soo do is not Olympic, and tournaments are held by individual organizations.
