NSNIS is away from Sports Bio-Mechanics : Netaji Subhas National Institute of Sports (NSNIS), Patiala India which is also Asia's largest Sports Institute is away from use of Matlab in accordance with optimisation of physical performance. Under mentioned content speaks in this respect.

Bio-Mechanic & Bio-engineering are absolutely different. Bio-Mechanic is meant by Coordination of Physiology, Anatomy and Design part of Mechanical engineering & etc. etc. Bio-Mechanic optimise physical efficiency. Bio-Engineering deals with gene & its related matter. Ergonomic is used in Industry to optimise comfort of work. Sports Bio-mechanic is used to optimise performance of sports, Dance & etc. Animation is needed for Children & Players. To work with multiple variables is needed for Sports Bio-Mechanic. Matlab is indispensable in this respect. T 's within the content.

Kinesiology too belongs to Bio_Mechanics. http://en.wikipedia.org/wiki/Kinesiology. _{Pl. click} Under mentioned caption is quote from the same.

NB : Respective parameters of Kinesiology may be handled independently. But, Kinesiology is implied within Bio-Mechanic by default.
England tried to analyse Bechham's kick ... What's its achievement ... few words for relevant topic :

Optimisation of Foot Ball Kick : Rotational motions of all limbs of body should work upon a Point of Contact between ball and foot at the time of Kicking the ball. Resultant force of all the rotational motions of limbs will convert to Linear motion and the said resultant force will work upon Point of Contact which exists between foot and ball at the time of kicking. The said particular point will move in a straight line along the target. Joint movement of foot & ball in a straight line is Length of Impact. Length of Impact is not considered in General Physics. Eg. Impulsive Force in accordance with Laws of Conservation of Momentum. ignore Length of Impact. But, Length of Impact is considered by Nuclear Physics to describe collision of molecules (Correct error-if any). Force/Velocity is directly proportional to Length of Impact & inversely proportional to time. It is theoretical part for optimising Kick. Matlab is used for calculation of multiple variables. Variables are rotational motions of the limbs. It is only for research, not for Players & Coaches. Players, Coaches & Children will follow Animated Demo to realise Length of Impact.

What happens when Beckham kicks ? Contact point of foot and ball moves in a straight line along the target of scoring. Length of this straight line of foot and ball is called Length of Impact. Length of Impact is not considered by Laws of Conservation of Momentum in General Physics. Length of Impact is considered by Nuclear Physics to describe collision of molecules. Rotational movements of maximum nos. of limbs convert to translatory/Linear motion (straight line motion) at the point of contact between foot and ball. Length of Impact is directly proportional to Velocity of ball. Velocity of ball is indirectly proportional to time. Mat Lab is to be used to calculate resultant force of rotational motions of limbs along Length of impact which is a straight line. Bio Engineering deals with gene. It is not concerned with Bio Mechanic.

 

What happens when Beckham kicks :

1. Any individual limb of body can not move in a straight line.
2. Each limb of our body moves with rotational motion.
3. To draw a straight line you will have to move at least two limbs of your body.
4. Beckham also draw straight line at the time of kicking the ball.
5. This straight line is drawn by the contact point of ball and his foot.
6. This straight line persists fraction of second.
7. This straight line is called Punch in foot ball and boxing, Lawn tennis calls it Cary the ball and Billiard calls it Follow through & etc.
8. Beckham produces this straight line with the rotational motions of his limbs. Rotational motions of his all limbs produces translatory/linear motion at the point of contact between the ball and his foot. This translatory/linear motion in a straight line is resultant force of rotational motions of his limbs.
9. The ball goes along the direction of this straight line. This straight line is made by the contact point of ball and foot.
10. This straight line may be called Length of impact.
11. Length of this straight line should be inversely proportional to time. Maximum length of this line in minimum time produces optimum force and velocity of the ball.
12. One corner kick comes with two motions. One is rotational motion and another is linear motion. These two motions act upon the foot at the time of kicking. The ball should rebound from the foot according to " laws of reflection ". This direction will not reach to goal. Player kicks the ball with force to send it to goal with his own experience. It is very common. Beckham also does the same. But why Beckham is Beckham !
13. How does it happen? How does Beckham control tendency of deflection of ball at the time of kicking? It is the cause! It is the cause of achievement of success to send the ball towards the goal. Clearance for scoring is always very narrow. It consists for fraction of a second. Kick should send the ball through the narrower space to get the score.
14. Length of Impact is the cause of it. Length of Impact neutralises the tendency of deflection of ball. This deflecting tendency of ball is followed by laws of reflection. Force works upon a ball in three directions for its (i) Rotational motion, (ii)Linear motion & (iii) Gravitation. Resultant force of them work on the contact point of foot at the time of kicking the ball. It rebounds from foot with laws of reflection. This direction of rebound is not the direction of goal for scoring. It is with high power/energy. It tries to deflect the ball from the desired direction of scoring. This deflecting tendency generates a power/force. Beckham is to neutralise this deflecting tendency of ball to send ball towards goal for scoring. It converts to heat energy & sound energy. It is the cause of neutralisation of deflection. Beckham can generate maximum Length of Impact in minimum time at the time of kicking the ball.
15. Rotational motions of all the limbs of body should produce resultant force on a particular point and in particular direction. It will optimise the force of body at that point. Beckham … How does it work on the point of contact between his foot and ball at the time of kicking the ball.
16. The chapter of Impulsive force in physics ignores this Length of Impact, but you will get it in the field of Nuclear Physics in post PG. Length of impact has been considered here to describe collision of molecules. Article on it is well come to be published here.
17. Research scholars of Aero Dynamics are equipped with the soft ware to calculate the above mentioned fact of happening. Indian scholars will not get guide for the same. Fastening of PhD degree is not possible with this topic to get increment in Indian college service. So, it is better to be avoided by the Indian college teachers.

Aero dynamics is highly equipped with software related to multiple variables. This will help to develop software to analyse the mentioned index. We will be obliged to publish research paper in this regard.

A paper on mentioned message had been made twenty years back with the idea of establishing a general equation with all the limbs of body to optimise the performance of work. But failed and only two limbs had been considered to form a general equation to optimise the performance with more than two variables. It should be done by multiple variables. Message maker is not competent for the same. It is the end of its knowledge.

Software is used for Aero Dynamics to calculate the effect of multiple variables. It is used only in first world. The same software is needed to optimise performance of sports as well as to optimise work efficiency in the field of Ergonomic.

It will be continued
