A Big Secret The Government Has Been Hiding About Backhand Power

Feelings, feelings, feelings...we all love for our tennis stroke to FEEL good...me included. If you have not tried to hit your two handed backhand with a longer axis of rotation then you really are missing out on a GREAT feeling. 

The cool thing about employing this fun technique is that it not only feels good but it allows one to obtain a mechanical advantage. This in turn provides the ability to generate more force with less energy. Now that is what they call a double whammy.

If you want to discover how to apply one simple yet powerful principle of physics to that two handed backhand of yours or your students...then keep on reading...​


Today's Backhand Power Instructional Key Terms 


In tennis the racquet and the arm together makes what science calls a third class lever. A lever can be defined as a rigid object that turns about an axis. Contractions of muscles create force to move the lever.

Increasing the length of a lever increases the range of motion at the end of the lever (the tennis racquet connected to the arm) and in turn increases the speed of the racquet (Ackland & Elliot, 2009). 

Body segment levers magnify speed because the moment arm for the effort is less than the moment arm for the resistance being moved.(Knudson 2007).

The longer the lever arm the greater the mechanical advantage... meaning the less effort required (That's a good thing). ​

Mechanical advantage:

A ratio describing the effectiveness of a lever calculated by the moment arm for the force divided by the moment arm for the resistance. The generation of more force with LESS energy...This is what we are after!

​In today's instructional we show you how to achieve a greater mechanical advantage merely by implementing this one reference point. 

Click the PLAY button below to watch the instructional and see how one can quickly generate more force with less energy on the two handed backhand (this technique takes more energy to initially get the lever moving but once going it takes less effort and provides a greater mechanical advantage than a shorter lever) by merely using the scientific principle of leverage...It rocks and FEELS great. If you have proper strength to perform this technique it simply provides EFFORTLESS POWER.

Please note this is only true if one has enough strength to move the lever arm effectively. If one is too young or lacks strength this technique might not be optimal until older or the strength is developed as it takes more strength to get longer levers initially moving... but if you are able to do so...once you do it's advantageous. As always test it for yourself...
