How long should you rest between rowing intervals?

In a rowing study using two maximal 1,000 m bouts, rowers repeated the second effort after 1.5, 3 or 6 minutes. Mean power recovery improved as the rest became longer, although performance was still not fully restored even after six minutes. The protocol was deliberately severe, so the exact numbers should not be transplanted into every training set; the important result is that recovery length materially changes repeat performance.

Research in elite rowers has found faster blood-lactate reduction during active recovery than passive recovery, with the higher of two tested active-recovery intensities producing the fastest lactate reduction. That does not prove faster lactate clearance always improves the next repetition, but it shows that “rest” has physiological content of its own.

Active recovery and passive rest are different session structures. Rowing Intervals can prepare either one, but the current CP/W′ pace forecast remains limited to seated passive recovery. Easy-row recovery can still be recorded, reviewed and compared with like-for-like completed sets.

Critical Power models can represent the expenditure of W′ during work above CP and estimate its reconstitution during lower-intensity recovery. Reviews of this approach conclude that it has practical potential while emphasising that individual W′ recovery kinetics are not fully understood.

Most of the detailed W′ reconstitution literature comes from cycling rather than rowing. Rowing Intervals therefore treats recovery modelling as provisional context around the set, not as directly measured physiology.
