The phrase "a peak work" is not correct in standard written English.
It may be intended to describe a work that represents the highest point of achievement or quality, but the phrasing is awkward and unclear.
Example: "The artist's latest painting is considered a peak work of his career, showcasing his unique style and mastery of color."
Alternatives: "a pinnacle work" or "a masterwork".
The relationships demonstrated that a lower 6MWD was significantly associated with a lower peak work rate, level of physical activity and HRQoL.
We found that men on average achieved a higher peak work rate and cycled longer during the CET than women; in spite of the fact the men were older with more impaired lung function (Tables 1 and 2).
As documented in Table 3, men exhibited 17% higher peak speed at a 62% higher peak work rate in the VO2max test (P < 0.05).
Although the proportion of patients with CET-Tend of 20 minutes was very small (2.5%), we evaluated the possibility of an underestimation in peak work rate that may result in unduly prolonged CET.
We sought to compare the results of CETs in a large clinical cohort to those of a 6MWT and we sought to determine how often a clinical cohort of patients with COPD achieved a maximal CET-Tend of 20 minutes during a CET performed at a predetermined 75% of peak work rate.
However, a fixed proportion of peak work rate exercise does not provide identical physiological stress amongst patients.
The intensity for cycle exercise training is normally prescribed from a percent of VO2peak or peak work rate (Wpeak) obtained from an incremental cycle test [ 7].
Therefore, evaluating patients with a CET at 75% of peak work rate leaves room for demonstrating improvement with an intervention, especially considering that the minimal clinically important difference has been reported to be between 100 and 200 seconds [ 9] or ~33% increased from baseline [ 4].
On a second day of testing, participants performed a symptom-limited incremental cycle test (ICT) to peak work capacity on an electromagnetically-braked cycle ergometer (Lode BV, Groningen, The Netherlands).
CET was performed on a cycle ergometer with a workload set at 80% of peak work capacity achieved during incremental cycle ergometry.
