Heart-rate data/Interval training (part III)

[John_W]

I've been doing another type of interval session on the treadmill in the last month - been doing this every Monday morning for the past 4 weeks.

The 1st time I did it it was hard... really really hard. Sweating buckets by the end, so much so I had to remove my t-shirt... the heat and sweat was irritating me so much. Good job there was no-one else around!

2nd time around it was the same thing. But last Monday and this morning it felt *much* more comfortable - I wasn't desperate for it to finish and I had more energy in the hours afterwards.

I've been curious to see the heart-rate data and lo and behold, it bears out my experience. The green and blue data show a quicker and deeper recovery and lower maximum rate.

So it's only taken my body 3 sessions to adjust and improve - I'm delighted with that.

Message is this: interval training (whether outdoors or treadmill) is a really *efficient* way to increase your fitness - I'm hoping that it translates into an increase in speed and endurance

The session is this:

3 min @ 9.5 km/h (jog)

4 min @ 13.5 km/h (tempo)

2 min recovery (9.5 km/h )

4 min @ 13.5 km/h

2 min recovery

4 min @ 13.5 km/h

2 min recovery

4 min @ 13.5 km/h

3 min recovery

I've done a load of others which I might post about some other time.

Ciao!

Love what you have done with the data here, and love your analytical approach. Validating things this way makes the lessons far more robust.

Thanks Tomas - my TomTom Cardio Runner watch exports any run as a CSV file, so easy enough to import into Excel and play about a bit

Very interesting post---I have been doing interval work on a treadmill---it is really hard work---I tend to keep the sessions short. I agree it has improved my fitness---I notice it in every day activities.

I really like the data you have printed--it looks like a good watch--I might have a look at getting one.

[John_W Graduate Ambassador in reply to harveyemm]

Thanks. Yeah, intervals are incredibly I find.

The watch is a TomTom Cardio Runner - they've updated to newer models of course. Any run data can be exported to the likes of Runkeeper or Strava but also, handily, to a CSV file format which makes it easy to import into Excel and play about with, like I've done above.

I think the Garmins with inbuilt heart rate monitors can export to CSV too.

Glad you liked the data

Really interesting, and makes that hard work worth it. I have just started doing 30-20-10 intervals - link here for details - runnersworld.com/peak-perfo...

it s hard but not impossible.

Hi,

Yeah, I've seen the 30-20-10 post of JuicyJu's. I'm not sure the 10 second bits will work on the treadmill but they can always be adapted I guess. I'd do it outdoors but my watch isn't that programmable. Maybe an mp3 player would work.

Thanks for the link and your interest

John

PS, love your username. I *love* cake

[Eatcakeandrun in reply to John_W]

yes I love cake too - that is why I run (partly!)

I use Endomondo, and have programmed an interval session on it, but it would be tricky on a treadmill!
