Does sprinting on grass improve relaxation? I think it does. My reason is simple. Charlie has stated that on slower tracks, it’s imperitive that athletes ‘wait for it’, and don’t try to force a faster rhythym than the track will allow. If one does a lot of sprinting on grass, they’ll need to learn to be patient, due to the slower surface. When they get onto a faster track in competition, their ability to relax will be heightened, because they will be running faster than what they’re used to, and won’t feel a need to push any harder. Thoughts?
Interesting theory, I’d like to know the answer this one also, thoughts?
Sprinting on grass can definitely be used in the GPP and early SPP but a transition to a competitive surface will be important for adaptation, technical development, and the advancement of top speed and CNS tolerance.
Easy sprints on grass can be used as recovery after overtraining, if needed.
My old coaches version of transition onto a competitive surface: “Ok kids, first competition of the year, put on your spikes for the first time of the year also, and run as fast as you can!”
If you have suffered from overtraining, what are some sessions you could do for recovery or to offset this? How long does it usually take to bounce back from overtraining/CNS burnout?
Ten(10) days
Thanks.
Well as I stated previously, what are some sessions that could be done for this ten day period to recover from this CNS burnout?
Also, what are the signs that you have in fact suffered from CNS burnout?
1-Tempo, submax sprints Preferably staying away form the shorter distances. EMS.
2- Feeling flat, dropoff in training times, sleeplessness, muscle twitching…
-
Be more specific when you say staying away from shorter distances? And what is EMS training? I have heard of it but please explain what it entails?
-
These girls are all novices so they may not know when they may feel flat. Training times have actually been ok. However I’ll take a closer look at that. This weekend at the meet the girls that I had a feeling may have been suffering from CNS burnout actually told me their muscles were twitching. They asked me why was this happening to them. I told them I dont know, that it could possibly be stress. I never even thought it was CNS stress though. Thanks QUIK.
1-limit speed work to distances over 80 meters and run at sub max
2-EMS-Electro Muscle Stimualtion (search on this site/theres plenty of info)However with the group you are working with it is not practical
-
So would the 85-90% range be sufficient?
-
I know exactly what EMS is. I used to get that done for my back. Anyway, I dont have any way to get this for them, so I won’t be using that.
Is CNS burnout the only cause of muscle twitching?
I’ve noticed muscle twitching along with overtraining of the CNS, but I’ve also noticed muscle twitching that was apparently independant of CNS burnout, after performing excessively high reps at extremely low intensity (for example, forearm twitching after long rows in choppy waters). Could muscle twitching be caused by structural damage to the muscle as well as by CNS burnout?
Thank You,

About sprinting on the grass, Kratochvílová and Kocembova used to run on the grass as much as possible in order to prevent injury. They did all their warm-up on the grass, and some complete sprint cessions too. To do that of course you need even surfaces. What do you think?
I agree with it. I would always do the same for warm-ups, not too sure about the actual workout though.
Muscle twitching is generally caused by localised muscular fatigue, caused by confused patterns in the active/rest fiber firing sequence.
I don’t believe CNS fatigue is as prevalent or as easy to incur as people often think.
For example it was several 60m, at various speeds and technique emphasis, with the fastests at 90% of their best time on the track, so assuming it was on the grass, it was close to max.
We could argue about the frequency of the various causes, but, due to the importance of the CNS, it always makes sense to rule out problems there, as part of the analysis.
Recently I’ve been yawning alot after sprints and weights. Is this a sign of CNS burnout?
I find when i start getting more sleep i’m yawning less! 
I guess yes, but more like a placebo consequence.
Also the most important thing about running in Grass will be the calf regeneration.
