75m laps intervals

[Valentin]

Hi all, I hope u are doing fine and having fun underwater !

A short question for all the advanced divers. I am swimming 50m laps on 1:30 to 1:40 intervals with bifins. 3x20min. Now I want swimm 75m laps in last 20min. (2x20min 50m laps + 7-8x75m laps)
What intervals are You guys swimming 75 laps with bifins? 2:30 or 2:45? Less or more?

50M on the 1:30 isn't too shabby. You can also swim them on a faster interval for more benefit...

I think an advanced diver can do 50's on the 1:30 for hours provided they do not swim at a sprint pace, but going to a faster interval or increasing distance you will probably get lactic and need exponentially more rest; it won't be linear... 50's on the 1:30 is my easy pool warm-up, I could do it until I am too hypothermic to know my name but 75's on the 2:15 would be much tougher to sustain.

Depending on how motivated I feel, for a main set I do 100's on the 2:30 or 3:00, 75M uw bifin kick followed immediately by 25M easy, for recovery and so I am not hanging in the middle of long course pool clogging the lane. At cruising speed I finish the first 75M at about 1:05. Sometimes I do the uw portion sprint and then I take a longer rest, doing them on the 3:30.

Great set for hard spearing or pre-taper DYN.

Hi Lance, tnx for the feedback!

You are good, a 1:30 interval is quite a struggle for me at the end, but I am working on it
My easy pool warm up would be 50's on the 1:45-1:50 at the time.

I will try the 75M on the 3:00 and see what happens, swiming to the wall right after 75m uw.

Hey, had so much fun today, swimming 75m laps uw in the pool. It was quite refreshing, adding 7x75m laps instead of usual 50m laps at the end of my training.
I swam 75m uw, than 25m on the back to the wall (20sec) and a pause for 2:20. It wasnt too hard. Next time, I will try to swimm 100m uw with one breath in between, after 75m uw, as You are doing it.

I think you misunderstood my post. The set I was doing is 75M uw, no breathing, followed immediately by 25M recovery, which means you can breathe or swim any way you want (I usually kick leisurely on my back or take a breath every 3 kick cycles), for a total of 100M. There are two minutes and thirty seconds between each start, so to do 7 of them would take me a little less than 17 minutes. That is 7x100M @2:30.

There seems to be some confusion on all these forums in how swimers and freedivers describe intervals. A lot of freedivers only time their rest interval, ie 6x50 @1:00 would mean six 50's with one minute rest in between each, whereas in swimming notation that would mean you start the next 50 one minute after the last one, regardless of how long it took you to swim the last one. I nearly always do my intervals like a traditional swimmer.

Hi, yes, I was wrong. When swimming 50m laps on 1:30, I count 45sec dive time and 45sec rest. I understand, I should do the same, when swimming 75m laps. I ll try it that way next time, should be more challenging.
