Did anyone else see the men's 100 meter final from the world Championships?
Gatlin was literally pulling away with his hamstrings in the final 20
meters, continuing to accelerate. Exciting race to watch!
Watching Gatlin pulling away, and listening to the commentator, I realized
that's just what I need to do to make my hamstrings stronger - Sprint! So
I'm dropping my bike cross-training and I'm adding sprinting to my schedule
😉
Actually, watching the race and especially the slow motion footage did give
me ideas when I was out on my lunchtime bike ride today. When biking with
cleats, you can use a smooth circular motion for pedaling, whereas with no
cleats, you're pushing the pedals through about 3/8 of a rotation only. I
never thought about trying to isolate the hamstrings when cycling, but today
I tried it.
I found that by pulling only, with my heels pressed into the back of my
shoes, I got a motion that very effectively isolated the hamstrings. I was
riding very easily, but my HR quickly leaped up about 10 bpm as different,
less-used muscles took over the majority of the work. I did about 15 minutes
of this, then eased for a few minutes before riding up the 6-7 minute hill
home.
This might be the answer I've been looking for since my race a week ago,
where my quads were find, but better endurance in my hamstrings would have
helped me on the flats toward the end. The cadence is different from
running, as probably is the range of motion, but when isolating the
hamstrings when cycling, they pull through a range of about 175 to 80
degrees, which isn't bad. I don't know what it will do to my calves.
Experimentation to come.
