In theory, tables of standards for power output for different durations could be generated by simply collecting data on a large number of cyclists of widely varying ability.
However, it is highly unlikely that any coaches or other individuals would have access to a sufficiently large database for this approach to be very accurate. As an alternative, estimates of power output for riders of differing abilities could be derived from actual performance, e.
The advantage of this approach is that it enhances the validity of comparisons across event durations, e. The resultant values for intermediate performances were then cross-checked against available data to assure that this approach resulted in valid guidelines.
Index efforts of 5 s, 1 min, 5 min, and at functional threshold power were chosen as those best reflecting neuromuscular power, anaerobic capacity, maximal oxygen uptake VO2max , and lactate threshold LT , respectively. This should NOT be taken to imply that, e. Rather, power output over these target durations would simply be expected to correlate well with more direct measurements of these different physiological abilities.
Secondarily, the index efforts were chosen in an attempt to increase reproducibility e. Some users may be prompted for a password. Just hit cancel a few times and the data will be loaded.
While each individual is likely to have a somewhat unique pattern that may change slightly over time, some typical patterns and general guidelines for interpretation are given below. In considering the following, however, keep in mind that performance at each duration is being evaluated in comparison to the world best — thus, in comparison to match sprinters, road cyclists will tend to appear relatively weak in 5 s and, to a somewhat lesser extent, 1 min power, whereas non-endurance track racers will likely have relatively low 5 min and functional threshold power relative to their abilities at the shorter durations.
The possibility of developing road and track-specific tables was considered but rejected, in part because many riders compete in both disciplines. Also keep in mind that, based on physiological considerations, an inverse relationship might be expected to occur between anaerobic and aerobic efforts—that is, someone who is great in aerobic forms of exercise, such as the Tour de France, may not be as strong in anaerobic forms, such as the match-sprint event on the track.
At the same time, however, a positive association might be expected between pairs. Although the scientific literature is in fact split on whether there actually is an inverse relationship between short-term and long-term power, there is clearly a positive association within each category.
The cyclist who is an all-rounder will have a generally horizontal plot across all the categories see Figure 4. The all-rounder does not necessarily excel at any one thing but is likely competitive in his or her category across a broad range of events. Given the fact that only specialists will likely truly excel at the extreme durations, very few individuals will show this pattern and still fall at the upper end of each range.
Instead, the vast majority of nonelite athletes will likely show a generally horizontal Power Profile because they have not yet developed specific strengths. This is a very common profile for beginning racers; as a racer or other rider trains more and more, those areas of strength will begin to reveal themselves.
A good sprinter will typically have a distinctly downward sloping plot, especially between the 1-minute and 5-minute categories see Figure 4.
Since aerobic ability is quite trainable, such an individual may be able to become more of an all-rounder through focused training; however, if the individual is a sprinter who has already been training hard for many years, he or she may have natural abilities in short-duration, high-power events. If so, focusing on events that favor these abilities, such as track racing and criteriums, is likely to result in success.
A distinctly upward-sloping plot again, especially between the 1-minute and 5-minute efforts, but also between 5 minutes and FTP is typical for the time trialist see Figure 4. This is because most time trialists are weak in neuromuscular power and anaerobic capacity, but they have relatively high aerobic power and an especially high lactate threshold.
Visit the Power settings panel in gnome-control-center and switch between performance, balanced, and power save mode. Look for unexpected behavior changes over long periods of time.
For example, selecting Performance mode should improve system performance but reduce battery life. Selecting power save mode should reduce performance but increase battery life. Selecting balanced mode should not change anything. The selected power profile should persist across system reboots in Fedora You can test in Fedora 34 as well if you install power-profiles-daemon manually, but note the power profile will not persist across reboots in Fedora User selection of these profiles will set various tunables to meet the needs as described in the profiles.
If not installed, these options will not be present in the power panel.
