Video analysis can be equally powerful for player and coach.
Overlay, with solid data, can reveal gaps in performance.
What do you see? Top player quicker time to 5&10 yds:
-Shorter GCT
-Equal AT
-Higher Freq.
-Higher Late Flex., Early Ext., and Late Ext. Thigh Angular Velocity

Retraction/flexion thigh ang. velo's are important, but are used to set up the ground thigh ang. velo's. Optimal range on ground in optimal time=⬆️ground thigh angular velocities.
Combo of qualities around hip ext., stiffness/reactivity of lower leg, and coordination of switch.
Sprint, to measure what matters.
Test your hip extensors in context.

Having a periodization plan for speed that loads/contrasts movements with specific direction of forces AND periodizing to higher eccentric speeds to shorten contraction times and increase peak forces. These are not always synonymous with “more load”.
Why do stronger players run slower! 🥲
🙋🏿♂️Hands up if you have observed athletes get stronger in the gym , vertical jump higher, broad jump further , but with little to no impact on their speed. 😖
🚩Heavy squats , and deadlifts are great for physical conditioning but often this

We have put years of coaching into this product. Contrary to popular belief, you CAN influence movement patterns in training environments that have transfer to on-field actions.
Measure, Coach, Change, Integrate. Combine closed concepts w/ sport specific ones to see transfer.
Self organisation is for LAZY coaches!
Elite coaches should verbalise all of the nuances of detail to maximise the performance of their athletes.
Video analysis should provide you with all of the granular data so that you can make minute analysis and provide the most specific

To threaten w/ speed & turn it on AT TIMES is powerful, but if you watch & talk to the greatest players @ their positions they speak to speed control not speed display.
Gamespeed=Anticipation, leverage, proper positioning, & COM control to allow sub max speeds to be effective.

Prescribing exercises to account for Projection, Switching, or Reactivity deficiencies can come in several forms:
Preparation for sprinting
During weight room sessions
Pre practice
Know why you are doing specific drills and how you are cueing them.

Projection , Reactivity, & Switching simplifies the complex ideas around kinematics…
It has helped us anchor what we see to deliver interventions that can drive meaningful changes.
Why does“Projection Switching Reactivity” work as a effective solution?
Because there is way too much data to refer to during sprint analyis. 🥵🤯

The work you do with your crew is incredible. Perceiving the environment is crucial to gamespeed, but throttling speed up and down smoothly & efficiently w/ timing is a skill that should be taught.

Using all three streams of exercises concurrently will ensure you are developing the motor unit recruitment, elasticity, and coordination to support and transfer to speed adaptations.

Can we use COD as a movement screen?
Is measuring deceleration, trunk/pelvic discipline &foot placement valuable?
Are there situations where these KPI’s are contraindicated?

Maximizes ground capabilities by being reactive, touching down closer to COM, and much better "switch".
Physical or technical? Profile, assess, analyze.
These types of analysis equally as powerful for rehab scenarios when comparing same player across time.

Using a portion of your sessions to teach to these positions can improve resiliency and expand and athletes movement options to those they wouldnt experience if only practicing sport repetitively.
