Maximal incremental tests might not be the best solution to monitor changes in performance after high-volume, low-intensity training period as a rower spends only 20-30% of the time during the incremental tests at low intensities.
Therefore, if a training period was intended to stress the low intensity energy systems then the measurement validity would be higher if we test the athlete using similar intensities.

2. Maximal incremental tests might not be the best solution to monitor changes in
performance after high-volume, low-intensity training period as a rower spends only 2030% of the time during the incremental tests at low intensities. Still, lots of coaches use
maximal incremental tests to test the performance of the athlete.
Therefore, if a training period was intended to stress the low intensity energy systems
then the measurement validity would be higher if we test the athlete using similar
intensities. Aerobic training has increased in recent decades in elite rowers and is the
most important type of training for them (Figure 1).
Figure 1. Changes in the distribution of training volume (h/week) between low intensity trainings and
high intensive trainings from 70s to 90s in elite Norwegian rowers (Fiskerstrand & Seiler, 2004).

3. The US national team, for example, has used different submaximal intensities for tracking
physiological changes in rowers during the annual training (Figure 2). The results clearly
show an improved lactate/workload relationship when the competition period advances.
Those constant submaximal intensity tests also give feedback about the capacity at a
certain workload. This is difficult to measure during incremental tests where we can only
measure different parameters at a certain intensity but we do not know how long we are
able to sustain the certain workload.

4. Biochemical testing during training intensity conditions should be preferred instead of
fasting (at rest) hormone test when studying biochemical adaptation of the low intensity
training. Rämson et al. (2009) indicated no change in fasting hormone concentrations
while a decrease in post-exercise concentrations of testosterone and cortisol were seen.

5. Conclusions
The validity of the performance test is higher if targeted to the same energy system or
capacity that was used during the trainings. So, when training aerobic capacity, tests
specific to that intensity should be used.
