2/ Velocity-based training is a method of training explosive force production that involves using real-time feedback on movement velocity
The training load can be quickly & objectively adjusted to achieve the desired movement velocity
3/ Velocity is typically measured by accelerometers, linear displacement transducers, or with a high-speed filming set up.
There are a number of commercially available options
4/ The force-velocity relationship of muscle indicates movement velocity is generally quicker against less resistance, but at the consequence of decreased force production
Max power is typically achieved at 1/3 the shortening velocity
5/ There are several reasons why one might want to use velocity-based training, here are five of them...
6/ 1. Load selection for maximal velocity
By recording the velocity of a movement against a known load, eg mid-thigh rack pull, the load can be objectively adjusted to achieve maximal velocity of movement.
7/ As an assessment metric
Training to increase RFD & power should be observable as higher velocity at a given load.
Eg Establish the testing load, say 50% of 1RM & record movement velocity pre- & post-training
Velocity post-training should be greater if you’ve designed your… twitter.com/i/web/status/1…
8/ To monitor training quality
Explosive-type training, unlike training for max strength, does not take reps to failure. That means your will still have reps in the tank at the end of the set.
9/ To account for inter-day variation in performance
Sometimes you just feel like a sack of spanners 😣 Or maybe you’ve improved 👍
By using velocity as a metric instead of % of 1RM, we can account for day to day variability in force output & can adjust the load to ensure the… twitter.com/i/web/status/1…
10/ What to do if you don’t have the 💰💸 to invest in the kit.
💥EXPLOSIVE INTENT of each exercise to achieve ‘fast’ specificity of training
Gross markers of movement velocity from phone apps could provide some some useful data
11/ Thanks for reading. Please head back to 1/ and retweet :-)
2/ DOMS is one of the consequences of exercise-induced muscle damage.
Eccentric (lengthening) ‘contractions’ can cause microtrauma to the musculature; shown as pockets of damage to the weakest contractile units (sarcomeres).
(Other changes also observed….)
3/ In those unfamiliar with high-intensity exercise, DOMS can be counterproductive to exercise adherence.
It can also be mistakenly interpreted for MSK injury 😕
It’s an unpleasant sensation & it gets worse following cessation of exercise 😖
