          Hello,

          Here is a video of one on my 100m runs, im the one in the white vest leading at 50m. https://www.youtube.com/watch?v=gZzWcNC5ha8

          I recently posted a video of some of my block starts on here and have tried to change a few things that some guys on elite track pointed out and all in all i think my start was one of my better starts of the season, however the same cannot be said for my final 50m of the race. Im not sure if its possible for you to tell from this video, but my opinion is that its a Max Velocity issue, i dont think it would be a speed endurance problem seeing as im 400/800 guy. any thoughts you have?

          Cheers, G

          u should test a flying 30 and maybe 150m that could give u a good idea. if i was you i probably would work on speed end 4×120 full recovery.

          It maybe a transition issue from acceleration to max V, a flaw in max V stride mechanics, or a relaxation issue.  Maybe its a combination of all these.

          you have a quite decent acc. phase,  however you seem to keep some foreward lean during maxV running and dont get your knees up.  im sure working on yur mechanics will help.

          What was your time for this run?

          That run was 11.5s Hand timed.

          Thanks for the feedback guys, will see if i can work on some of the aspects you have picked up on.

          I agree with Flow on your acceleration.  I find it hard to believe that it could be a speed endurance issue.  Although 400/800 is special endurance work, speed endurance is also worked there.  it could be a maxV issue, but your accel usually determines your maxV capabilities and if your maxV is hurting after your acceleration I came to the conclusion that you need more form refinement going from accel to maxV  (50-60m sprint work in your case)  and work on maxV mechanics as well as relaxation.  Lots of mids tighten up in sprints, those of you who kick well generally have good acceleration mechanics, but have trouble transistioning at higher speeds.

          agreed with danimal.  you were out of the blocks way to fast for it to be a speed issue.  your top speed form and transition look suspect, though it is hard to tell from the video quality.

          Ok, a year on from this race and although times have come down from mid 11's to low 11's, im still suffering the same problem as seen in the original video.

          Anytime im starting out of blocks i have trouble getting my knees up infront of me, excessive backside mechanics. ( one coach noted that my legs seem to continue in a piston like manner even once acceleration has completed, still pushing rather than pulling.)  I dont notice the problem on flying runs because i build up gradually without the hard acceleration phase.

          Here are a few more recent videos:

          https://www.youtube.com/watch?v=JARJXlTtCZE –  60m ( inside lane)
          https://www.youtube.com/watch?v=VdL3dg17ob0 – 400m (inside lane)

          This one may not be relevant as its only 10m from blocks.

          https://www.youtube.com/watch?v=OZg9SpUo82w – 10m ( middle lane)

          The quality of the 60m has been lost slightly since uploading to you tube so i will get some still's off the original and get those up later.

          Thoughts?

          Thanks.

          re: backside mechanics
          looks to me like what is happening (in the 400) is that you are trying to fold your ankle to your buttocks, THEN swing your leg forward. the action should be lead by the knee driving forward with the folding of the lower leg following, rather than preciding the knee drive.

          your start looks good, maybe your first few steps could afford to be longer both in contact time and stride length

          agreed.  by the way, sprinting should be thought of as a pushing action rather than a pulling action

          thanks guys, is this something that if i work on in practice i will be able to rectify?

          can it be related to any strength imbalances? or is it just purely through learning.

          thanks.

          of course you can improve with practice, just be sure to focus on one thing at a time

          i would think 'step over' as in step over the knee of your support leg with the ankle of your swing leg – this will cue your knees out in front and less backside mechanics

          not sure about the strength imbalances but i doubt it

          post us another video after a few weeks of focusing on this!

          thanks!

          Well i went to practice tonight and did sprints. I was focusing on stepping over the knee of the support leg. It was showing improvement in knee lift and overall mechanics. So will continue to work on it. I will post video footage in a couple weeks for some comparison.

          Here is my 200m from today, 22.8 = PB.

          I have been working on my max vel mechanics, still much work to go.

          100m to follow.

          my thoughts are that as usual i thought my position out of blocks and accel phase were alrite, but once at top speed was quite tight and shoulders were rocking .

          You run 400s dont you? So relaxation you should be comfortable with, keepin shoulders loose etc and keepin the hips high will help your 100m.

          In the 200 you should work on bend runnin abit more,
          try runnin from the 120m mark the 80m – usin different techniques each time
          (leanin into the bend / runnin right on the line / turnin your shoulder towards the line etc)
