Is it safe for me to start sprinting?[/quote]
Almost surely, yes.
You know, before the internet, there was really no way for people to check-in BEFORE picking themselves up and just getting after it already. And this was prob a good thing.
Teared hamstrings are NOT a good thing.[/quote]
More internet melodrama. I don’t think its coincidence that hamstring pulls/tears by non-competitive amateurs is now so worrisome/commonplace.
Anyway, the advice from others is good. Ease back into the groove of running and pick up speed with each workout. But also, just get started already.
I have seen way too may tears on people coming to our track and field team fresh new, sprinting at 100% after a week, and pulling their hamstrings within the next month. Especially eople who are just good sprinters by nature.[/quote]
I rarely see people doing more than jogging, and to be honest I don’t even see correct running mechanics where the hamstrings are definitely firing all that often either. again, speaking of non-competitive amateurs.
With normal people it is less mechanics than sheer tightness, bad muscular endurance and bad mobility all combined together in an accident waiting to happen. It’s not that sprints are injury inducing things themselves so much as the fact that a guy who has trouble riding his bike for 5 minutes without gasping for air and has been sitting with completely immobile and shortened hamstrings for hours a day every day is asking for trouble to start sprinting right away.
He’s got to get used to running before sprinting becomes a great tool IMHO.[/quote]
Completely agree with this. I really like one day speed work (not all out, max effort), one day tempo (longer, “comfortably hard”) run and one long (for you), easy pace run as a jumping off point for integrating running into your training.
