Hey hey,
It’s time to boogie. This post will serve as our discussion thread for all things week 1: ASSESSMENT AND READINESS
Lets gooooooo!
Hi everyone,
After listening to Casey speaking about evaluation and data interpretation I have 2 questions:
1) How 10y / 20y / 10y fly relate each other. When they can be considered “consistent”?
I think I did not understand the thinking process behind these data relationship and interpretation.
Aside from data collection, I would like to understand better how they influence my decision making during programs design.2) How 5 hops distance relates to 10 and 20 y sprint times. How would you determine if it is necessary to work on mechanics or strength qualities (e.g, horizontal projection angle/force application angles vs unilateral lower limb strength)?
Thank you!
Marco
Coach! Amazing questions…I have your questions and my answers below
Other coaches, please, feel free to chime in
1) How 10y / 20y / 10y fly relate each other. When they can be considered “consistent”?
I think I did not understand the thinking process behind these data relationship and interpretation.The biggest thing to look at is that as an athlete performs a 10/20 yard sprint, is that each 10 yard interval should be faster. 0-10 yards is the slowest, 10-20 yards is faster.
What I have traditionally done in the past, is to have the athlete run 2 attempts and compare.
If the 0-10 yard time varies within .07 of a second, I consider that variation to be normal. Anything greater than .07 is probably due to a mechanical change the athlete made (arm swing/ length of first step/ body angle). This variance holds true whether it be positive (athlete got a faster time) or negative (athlete got a slower time).
It’s hard to say what the incremental change in 0-10 yards and 10-20 yards should be, however I think it should be greater than a full second of improvement.
Example- if a 0-10 yard spring measures at 2.5 seconds, then the 10-20 yard split should ATLEAST be 1.5 seconds. Traditionally I see athletes have a superior 10-20 split than 0-10, simply because of the human error in navigating the start position and/or a timing system.
Aside from data collection, I would like to understand better how they influence my decision making during programs design.
2) How 5 hops distance relates to 10 and 20 y sprint times. How would you determine if it is necessary to work on mechanics or strength qualities (e.g, horizontal projection angle/force application angles vs unilateral lower limb strength)?
When breaking down the evaluation, I don’t normally compare X test to the outcome of Y test, rather, I think each test shows a unique athletic skill. Sure, there can be correlations, but for the purpose of athletic improvement, each test is valid in assessing its unique skill.
In the case of the 5-hop broad jump, and the scope of youth athlete Parisi works with, we like to see the athlete jump their height 5-times over. This shows consistent power production and an assumption that loading and landing mechanics are sufficient for training. I do like the assessment data Functional Movement Systems (FMS) says where higher performing athletes should be able to jump 120% of their height in a single jump attempt. If I have a high performing athlete, I will measure their first, single, broad jump, note it and then continue with the remaining 4 jumps for the Parisi 5-hop measurement.
