| Sujet: (anglais) Suburi - a scientific study Mer 22 Juin 2011 - 13:58 | |
| Le document est en anglais, alors, j’écris en anglais aussi pour cette fois-ci. SUBURI SWING SPEED STUDY2 Japanese senseis (7 dan) did a series of study on 10 subjects, 5 experienced kendokas and 5 untrained subjects, to determine the effectiveness of suburi, with focus on: - Swing speed
- Muscle relax speed after the swing
In the study, they found out that the fastest suburi has the following characteristics:
- The left hand's grip should not be completely relaxed before the swing
- The shinai's starting position should not be too low
- The shinai's stopping position should not be too low either. Ending the shinai's cut when the right hand reaches shoulder's height makes it hard to relax muscles
- 3 groups of muscles should be used in succession: shoulder, elbow, and then wrist. A common mistake is excessive use of shoulder and wrist muscles without enough elbow movement => more fatigue, less speed
I find the study to be very well explained and helpful. Hit up the link and check it out if you're curious | |
