its good to see you back, can't wait to explore how you will do in new place and your feeling about warm weather and environment. Very excited to see what new chapter in your life will unravel.
Hello again... Sorry for the long screed below: 😆 Just a few things that you might want to consider related to MaxV... TL;DR -- Timing, timing, timing... and racing flats. 1. The shorter the flying sprint, the more critical timing becomes. Otherwise you are essentially "flying blind". (No pun intended...) It is very, very difficult to time something as short as 20m without having either timing gates (very expensive) or some sort of proximity-based system (i.e. Freelap -- still a little expensive, but less so). Video analysis is the next best choice if Freelap is not an option (although the one downside to video analysis is the delay between the performance and receiving the result -- which might mean that the neural learning part of sprinting is not as efficient because you don't get to benefit from the dopamine response you receive from immediate feedback in helping to solidify neurological pathways.) Video analysis also doesn't work as well for flying sprints since it is difficult to get proper vantage points for accurate detection of the start and end of the interval. It does work well for sprints from a block start (assuming you have another person to run the camera, who can stand at the finish line). 2. Flying 10m sprints have problems. I wouldn't recommend using the 10m distance. It is preferable to do 20m flys instead (or even 30m flys). This is because the 10m distance is too short to be accurately timed by anything but the most expensive, photo-based systems. Even timing gates and Freelap don't work well for 10m sprints because the variances in each case (breaking the plane with an arm or leg in the case of timing gates; magnetic field variation and sensor response delay in the case of Freelap) can be up to 0.04-0.05 seconds at your speeds. This is too large for an interval as short as 10m unless you are very meticulous about statistics and are able to accept taking averages and not getting too excited about a "PR" (since all of your times will be subject to the ~0.03-0.05 variation.) In addition, since it takes 20-30m to get up to speed anyway, you might as well try to spend 20m at max velocity instead of just 10m. It's a more efficient use of effort. (Again -- 30m flys might even be a better idea than 20m flys... just something to consider) I know that 10m flys are popular (especially due to the likes of Tony Holler), but most people don't really think too much about the statistics of their timing systems. (I have personally measured my own Freelap system and can report that the variance in detection distance between a single sensor and cone is ~20cm, so you're really talking about a range of up to 40cm per interval, since you have a start and an end cone.) 3. You might want to think about acquiring some "flats" -- i.e. something like (spikeless) Nike Waffles, or some other "racing flat"-style shoe. It looks like you're using a heavier-duty trainer -- there's nothing wrong with this, but it will add time to each ground contact due to the lower effective "spring constant" that more cushioning gives. (That is, a more heavily-cushioned shoe will take more time to absorb and return the energy of each foot strike, and this will tend to increase your ground contact times, which are the limiting factor in maximal velocity running.) You can still improve your sprinting while using thicker shoes, but at some point you'll want to optimize and get used to the harder, faster contacts that are provided by a thinner, "flat" shoe. I should also point out that a sprint spike is probably *not* a good idea yet since you appear to be training on an *extremely* hard surface. Indoor track surfaces are notoriously hard -- especially older ones. You'll probably want to just get more running under your belt (and improve the structural integrity of your lower legs) before introducing a spike.
very good forms and good angels too.🙌👏

Still waiting for the day when pogo jump will be 3 hops!!
Really nice work
Cool!
What are the sneakers?
@@Ryan_Archmjr242 ?
Awesome work.

wat NB shoes r they?
