What is maximal aerobic power?

Maximal aerobic power refers to the power output that the rower can generate using mainly aerobic energy pathways. It is a power output that corresponds to the maximal oxygen consumption intensity.

As maximal oxygen consumption is one of the most important determinants of being a successful rower, this parameter is one of the most frequently tested. Compared to other endurance disciplines, maximal oxygen consumption in rowers is one of the highest.

X-country skiing 6.1 4.3

Kayaking 5.3 4.1

Running 5.1 4.0

Cycling 5.4 4.1

Maximal oxygen consumption is described as a paramater that can level off. It has been found (Steinacker et al., 1998) that when rowers reach approximately 5000 km per year the indices of VO2max may not correlate well with rowing performance, while peak power during incremental test is much better predictor (Messonnier et al., 1997).

It is usually noted that year-round changes in VO2max are often smaller than changes in peak power. Therefore, taking into account the previous concerns, performing the incremental test without oxygen mask to measure peak power only, can be of high importance in practical setting.

Aerobic power testing with the peak power of the incremental test

Rowers usually perform at approx. 95-97% intensity of their maximal aerobic power during a classical 2000 m distance. As maximal aerobic power and peak power during the incremental test are highly correlated (especially in younger rowers, Jürimäe et al., 2000), we can take the 95% of the peak power as a reference.

The rower should perform this constant load test as long as possible. The test result will be the time – how long the rower can hold the test intensity.

For example: The heavyweight male rower has a peak power during the incremental test of 425 W. Now we calcualate 95% of it (404 W) and the next test will be to row as long as possible at constant 404 W load.

If we compare peak power and 95% peak power test, the last one would be even more sensitive for describing performance changes. It has been shown that besides elite rowers having higher peak power values, they are also able to row at 95% test for longer time compared to lower performance rowers (Jürimäe et al., 2000).

95% power test

1. As the test intensity reflects the power that the rower uses during the 2000 m, it is a very precise measure of competitive performance.

2. The test has shown higher predictive value compared to VO2 max testing (Jürimae et al., 2000)

3. It is very practical to use for coaches for routine testing, even for young rowers who perform incremental test with VO2 measurements rarely.

4. The best way to track 95% test result is to make an incremental test shortly before it. However, if not possible the peak power value from the last incremental test can also be used for several tests.
