Movement away from a specific point is DISPLACEMENT
Distance and Displacement are not always the same.
Velocity  - time taken to get to a certain point
Acceleration can be positive and negative - it's a function of changes in velocity and time taken.

Very easy to read - ankle is basically irrelevant for force production, Hip and Knee more important.

On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration."]]> 2019-11-14 12:43:39 UTC https://padlet.com/rich110277/ltts2cnlm70n/wish/411138731 rich110277 https://padlet.com/rich110277/ltts2cnlm70n/wish/411141802

Examined the impact force, the relative impact force, the execution time and the relative execution time, of a roundhouse kick to the chest among three Olympic taekwondo weight categories (20 Males).  

No differences in impact force between featherweight, welterweight and heavyweight. 

The featherweight group generated more relative impact force than the heavyweight group.

heavyweight group used longer execution time when performing the roundhouse kick than both the other two groups, and had a longer relative execution time than the welterweight group 

Reducing the body weight immediately before competitions to compete in a lower weight category does not seem a priority option as it will not necessarily improve the performance.

• Repeated measures showed that the experimental group (EG) improved significantly (Po0.05) maximum ball speed, the linear velocity of the foot, ankle and angular velocity of all joints during the final phase of the kick. 
• Training had insignificant effects on  electromyographic (EMG) values.
• EXCEPT increase in the averaged EMG of the vastus medialis whereas maximum isometric strength and sprint times significantly improved after training (Po0.05). 
• Results suggest that the application of the training programs using soccer-specific strength exercises would be particularly effective in improving of soccer kick performance.

This study uniquely showed that muscular enhancement capacity is not only related to the power capacity of contraction but also to motor coordination."
Therefore skill (bio mechanical effectiveness) and muscularity combine to create power....]]> 2019-11-14 13:04:05 UTC https://padlet.com/rich110277/ltts2cnlm70n/wish/411146812 rich110277 https://padlet.com/rich110277/ltts2cnlm70n/wish/411150005

parameters such as maximum kick foot velocity, duration's of take-off, the upswing, the downswing as well as the whole kick and the kick leg angle at maximum velocity were quantitatively determined.

The results indicate that the maximum kick power appears around 45º of the kick leg to vertical direction or 85-89% of one’s body height

keys for increasing the kick effectiveness are balanced weight transfer, large hip ROM for pre-lengthening hip extensors and follows an explosive foot downswing for maximizing kick-foot power.

The maximal kick power occurs around 45° of the kick-leg to the vertical direction during the downswing; shortening the downswing phase could increase the axe kick quality further.
