... Some studies show better results from very short intervals (say 10-14 reps of 30 seconds at absolute max followed by 15 second recovery), others say longer intervals (say 4 reps of 2K at highest output you can sustain and still complete all four 2Ks) are just as good... All intervals have up to 2 min rest between work.
Studies show more than 2 mins rest does not help.
Sorry coming back so late to an earlier point, but this is new to me. Would be very interested in the studies concerned as it is contrary to many of the common rowing plans. Either I do my intervals at too high an intensity (which is unlikely given the refrain that amateurs don't go hard enough) or I am missing something. I agree that a complete stop for longer may not bring any benefits, but an easy recovery to keep the blood moving definitely helps, but as a very slow and week rower I am in no place to judge the efficacy of a plan for serious rowers.
Hi, glad you are interested. Think we both agree some hard intervals should be in training plans, and are both talking about how long to rest between the hard intervals. For example, if you are doing four hard 2K rows, will 3 or 4 mins rest give you a better workout than 2 minutes rest? Conceptually it seems 4 mins would give you more ability to go harder on the next 2K piece, however study results seem to show that (1) there are no gains from greater than 2 mins in effort for the next piece and (2) if you hide the clock and tell people to rest until they recover then people choose about 2 mins then start again.
EDIT: "rest" above means active rest - slow paddling. Complete stop would be bad. I should have used different terms. Active slow paddling also means the PM5 is recording your heart rate as it peaks then comes down - you get data on each stroke you do.
Here is the study I relied on for
Studies show more than 2 mins rest does not help. The actual text is easier to read than the somewhat stilted wording from the conclusion I'm pasting here for people who won't read the source. It's here:
https://journals.lww.com/acsm-msse/Full ... nd.21.aspx (FWIW I changed from 3 mins rest to 2 mins based on this, and am looking at changing my 30 second on max, 90 second rest intervals to have a short rest based on a different study. Haven't firmed that up yet).
Results: Running velocity increased slightly (14.7 +/- 0.7 vs 14.4 +/- 0.8 km.h(-1), P = 0.02) when rest increased from 1 to 2 min,
but showed no further increase with a 4-min rest (14.7 +/- 0.6 km.h(-1). Work VO(2) was slightly higher with a 2-min rest duration compared with 1 and 4 min (66.2 +/- 4.2 vs 65.1 +/- 4.2 and 64.9 +/- 4.7 mL.kg(-1).min(-1), P < 0.05). Peak blood lactate was similar (6.2 +/- 2.6, 6.8 +/- 2.9, 6.2 +/- 2.6 mmol.L(-1)) across conditions, whereas peak RPE was slightly lower during the 4-min rest condition (17.1 +/- 1.3, 17.7 +/- 1.5, 16.8 +/- 1.5, P < 0.05).
With self-selected recovery time and no knowledge of elapsed time, the average rest duration was 118 +/- 23 s.
Conclusions: Under self-paced conditions, varying rest duration in a range of 1 to 4 min had limited impact on performance during repeated 4-min high-intensity exercise bouts.
Approximately 120 s of active recovery may provide an appropriate balance between intracellular restitution and maintenance of high VO(2) on-kinetics.
