Ahahaha, yes, yes they are!
Wow, I just stumbled upon a video I have from almost a year ago. This was me about 4 months post-op from hip impingement surgery, with absolutely ZERO sprint training prior (yes I’m an idiot lol). I was about 10 pounds lighter too. Already accelerated for 30m before the vid starts. Video is 30 frames per second
I wish I had the raw video because I used some editor at the time to splice the video and I lost a good segment of the run, but I was pretty quick in that vid. Arm swing looked decent , my stride looks pretty open too.
