Jing Tan Li 驚彈力

[Yeung]

I think Wang Xiangzhen coined this term "驚彈力 Jing Tan Li" which means stunning or causing a shock, and it should be something like Fa Jing the Chen Taijiiquan people often talk about. Have a look at the following video from China, but you have to wait a while for the advertisement:

Section 3 of Wang Xiangzhai's "The Correct Path of Yiquan" translated by Paul Brennan:

用勁
[3] APPLYING POWER
拳術之妙，貴乎有勁，用勁之法，不外剛柔方圓，剛者直竪，柔者靈活，直竪長伸有攻守力，柔者縮短有驚彈力，剛勁形似方，如圖，
Effectiveness in martial arts depends on having power. Methods of applying power do not go beyond hardness and softness, squareness and roundness. Hardness is straightness. Softness is lively. Straightness is extended long, having a force of attack and defense. Softness has a shorter range, having a force that is sudden and elastic. Hard power seems to have a squareness:

Paul Brennan translated Jing Tan Li as a force that is sudden and elastic.

Just came across this link of Chen Xiao Wang:

From both examples of Johnwang and Chen Xiao Wang, there is no springiness and mentioned by Wang Xiangzhai; his observation was that the " Softness has a shorter range, having a force that is sudden and elastic". Both examples demonstrated the power of pushing and striking but lack of elasticity or springiness. Maybe the following post on the experiment with Fa Jin might be useful:

Experiment with Fa Jin, East Midlands, August 2018

From the classical literature of Taijiquan, Fa Jin has the following characteristics:

1, Store and then issue
2. Store power is like opening a bow
3. Issue power is like shooting an arrow
4. The requirement is the coordination of above and below

Fa Jin is a combination of stored power and generated power to issue an explosive type of power with the coordination of movements of the upper body and the lower limbs. Traditionally the body is described as the movements of 15 joints of arms, legs, and the spine in generating a straight line of attack.

The experiment with Fa Jin sessions will work through various techniques from martial arts that does not use brute force every Saturday from 10 am to 1 pm in August 2018 at the upper hall of Trinity Methodist Church Centre, Royland Road, Loughborough, Leicestershire, LE11 2EH.

Participants will be shown the following:

1. Eccentric strength
2. Stored elastic energy
3, Utilization of stored elastic energy with eccentric strength
4. Utilization of incoming force with stored elastic energy and eccentric strength
5. Practice Fa Jin in various techniques that known to them

The aim of these sessions is to experiment with various possibilities of Fa Jin in martial arts to verify the non-concentric exercise model, and to identify observable differences between pure eccentric strength and combining with stored elastic energy.
