Isometrics for speed?

by Khalil

I was wondering if using dynamic isometrics would make me a faster sprinter? I heard that it can recruit type IIb muscles, and I was wondering if this was true. I'm looking to get a lot faster in the 100 and 200, so I was thinking about isometrics.

Isometrics for Speed
by: Jarell

Hey Khalil! 'Dynamic isometrics' is an oxymoron, because isometrics in their nature are static. There are dynamic tension exercises, which is tensing through movement, and isometric exercises, which is tensing through maximal static effort.

Both forms of exercise are fantastic for generating speed.

Isometrics is based on stimulating your fast twitch fibres. The nature of isometric training substantially increases the neurological strength and co-ordination. In other words, your brain and transmit the signal to contract your muscles faster, thus your muscles move faster and with a higher number of fast twitch fibres you’ve moving much faster.

Forcing the most out of your muscle(s) in a particular position for a specific length of time, you will begin to recruit and activate more and more motor units to help maintain this contraction. Motor units that are rarely exercised within a particular muscle are now brought into use with isometric training.

The motor units that are recruited are forced to contract continuously, time after time, with no appreciable or progressive increase in force output. This forces muscular development and increased neurological efficiency while allowing you to achieve this state of maximum force very safely and effectively.

Plus, slow is smooth and smooth is fast. Training the movements in different isometric positions or with slow but intense dynamic tension movements will improve your neural efficiency in sprinting.

Hope that helps! Happy training.
