Biomechanics References on Tennis Strokes
 
I recently found some references mostly by tennis biomechanics researcher Bruce Elliott and associates. I found them very interesting.

If you have some similar references please reply.

1) Two minute interview with Bruce Elliott on biomechanics, tennis, and coaching. Refers to the book

Technique Development in Tennis Stroke Production(2009), B. Elliott, M. Reid & M. Crespo

http://www.youtube.com/watch?v=_0qJjqzWaDA

Amazon, Barnes & Noble, etc. all list it as ‘out of stock’. No wonder I had not heard of this 2009 biomechanics book on tennis stroke techniques. I found it for sale at the ITF Store. $20.

2) Paper - Biomechanics and Tennis, Elliott (internal shoulder rotation on the serve)

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2577481/

3) An Australian tennis website includes video discussions-

Instructional videos from a coach development workshop including 2 part Bruce Elliott & M. Reid video on the forehand. The first part is 56 minutes long and the first minutes are about foot work. Most stroke swing information starts at about 30 minutes.

(Note at the top of the webpage is a code to view the videos.)

Usually indicates 'view free text' somewhere but that phrase is not a link. For example, http://www.ncbi.nlm.nih.gov/pubmed/17513331 show abstract and link for paper #12.

(I thought that an ISBS biomechanics conference in July 2012 was to have a session on tennis and a special ITF tennis publication. But just learned that there’s no special session on tennis and, I guess ?, no special issue on the latest tennis research.)

Fantastic post, I went to one of these conferences a few years back. Was educational!

Biomechanics Course
 
"The goal of BME 473 is to teach the fundamental concepts of movement biomechanics with an emphasis on how muscles produce movement."

http://rrg.utk.edu/resources/BME473/...html#Lecture11

The interesting question for tennis is - How are the fastest muscle shortening velocities produced?

Titin - Some new research on muscle stretch.
 
I may have misunderstood this picture of new research related to the stretch-shortening cycle on the microscopic scale.

The Hill Muscle Model shows the functional components of a muscle on the smallest scale. It provides a way to visualize what is going on and to think about how active muscle components (actin & myosin) and passive muscle stretch component (recently also the Titin protein molecule) might function.

Recently, new research has emphasized the role played by passive Titin, the largest protein molecule, also located within the sacomere in parallel with the active Actin and Myosin structures. Recently it has been considered that Titin in each muscle cell provides the main stretch capability of the muscle. An older theory views stretch as an overall muscle stretch to include tendons.

New research on Titin
http://www.umag.ca/issue/spring-2012...le/clash-titin

This report in Figure 7 proposes a new way that Titin might be interacting with Actin to provide stretch functions.
http://ajpcell.physiology.org/content/299/1/C14.full

I don't understand this last research but maybe it implies that a stretch can be deliberately activated at various lengths of the muscle.

This new research might be especially important along with other research that indicates muscle shortening might be faster if 'passive' stretch is employed instead of active muscle shortening. (the Actin -Myosin animation above even looks slow).

In Biomechanics of Advanced Tennis (2003). Elliott said

"10-20% of additional racket head speed is achieved following a stretch shortening cycle."

(This publication is now 10 years old so there may be different views in 2013.)

Is that a simple addition to racket head speed or is passive stretch derived muscle shortening the only mode that can shorten that fast with control and reproducibility? Main principle of athletic movement?

See Figure 4.


"5. Conclusions

Players of all ages appear to prepare their bodies and generate racquet velocity similarly in both
successful and unsuccessful serves. The similarity in discrete body kinematics suggests that service
faults cannot be attributed to a single source of mechanical error. However, service faults are characterized
by projection angles significantly further below the horizontal, suggesting that this parameter
is a determinant of serve outcome. Similar to other dexterous skills, compensatory variability in the
distal (elbow and wrist) joints immediately prior to impact appears critical to the regulation of projection
angle, as it allows players to adjust to the variable impact location. Given that the impact location
cannot be predetermined, perceptual feedback may play an important role in the compensation
process. For this reason, coordination of the distal degrees of freedom and a refined perception-action
coupling appear more important to success than any single kinematic component of the service action.
With this in mind, the development of a highly adaptable movement system may be more beneficial to
improving serve performance than traditional approaches that decompose and accentuate consistency
in the service action. Explicitly, coaches may command varying service performance (speed, spin, location),
scale the court dimensions, or administer stochastic perturbations of the ball toss early in development
to foster the mechanical and/or perceptual proficiency required in the tennis serve."
