Abstract
The 3-min all-out test was developed and validated on a cycle ergometer using a modification
of a linear mathematical equation (1/time vs. power) obtained from the original critical
power model. The purpose of this development was to obtain, in a single test, the
aerobic and anaerobic capacity parameters and identify the exercise transition moment
from heavy to severe intensity. The aim of this study was to propose an adaptation
of the all-out 3-min cycle ergometer to a non-motorized treadmill with tethered running.
In addition, we tested the reproducibility of this adapted protocol, highlighting
the need for mechanical power evaluation using a specific ergometer. Consequently,
10 physically active individuals visited the laboratory 4 times for testing and data
collection. The results suggested that the protocol adaptation for the 3-min all-out
test for non-motorized treadmill with tethered running was reproducible and feasible.
It was also possible to show that the AO3 application in this ergometer ensures the
specificity of the sports that involve the running exercise, from assessment of both
aerobic and anaerobic parameters, accomplished in a single day of application.
