Stumbling

During my some of my sprint reps I sometimes stumble slightly. I don’t have access to a video camera anymore so I can only go by what it feels like.

It feels as if the previous stride was too quick and on the next stride I’m unable to get my foot moving back quickly enough and consequently the foot lands ahead of my centre of mass causing a sudden stumble.

What is going on here? I want to correct this error as quickly as possible as I feel it could lead to a serious hamstring pull.

I don’t know if this is the same problem you are having but i experience the same sort of stumle in the drive phase. I think it is a result of staying to low and not generating enough vertical force early on causing my foot to land to far forward and very flat footed. I correct this conciously increasing the vertical force to raise the hips higher and thus alowing the foot to come under the hip on foot strike. This might also occur at max speed where vert force is dominant, in this case it could be a result of pushing off to far behind the body.

Do you do your starts on a grass track? Your foot may be hitting a uneven divit of grass or such, and through you off course enough to stumble. Maybe?

I completely know what you mean! I have been told on numerous occasions that becuase i lean forward too much, resulting in my centre of gravity being too far behind me, thus resulting in me stumbling. I’m slowly but surely correcting this, but damn it’s hard without seeing yourself doing it first!
Does anyone have any ideas as to how to correct this??
