Determination of Submaximal and Maximal Training Zones From a 3-Stage, Variable-Duration, Perceptually Regulated...

Area of Science:

• Exercise Physiology
• Sports Science
• Running Performance

Background:

• Maximal oxygen consumption (VO2 max) is a key indicator of aerobic fitness.
• Recreational runners often lack accessible and validated methods for determining personalized training zones.
• Field tests offer a practical alternative to laboratory-based assessments for VO2 max.

Purpose of the Study:

• To validate the Running Advisor Billat Training (RABIT) test, a novel self-paced maximal oxygen consumption field test.
• To assess the RABIT test's utility for recreational runners in defining personalized training zones.
• To compare the RABIT test's results with a standard laboratory-based maximal exercise test.

Main Methods:

• A cross-sectional study involving 12 recreational runners (mean age 43 years).
• Participants completed three maximal exercise tests: two RABIT tests and one University of Montreal Track Test (UMTT).
• The RABIT test involved self-paced efforts at specific Rating of Perceived Exertion (RPE) levels, while the UMTT was a continuous incremental test.

Main Results:

• The RABIT test and UMTT yielded comparable mean maximal oxygen consumption values (P = .722).
• Cardiorespiratory and speed responses during the RABIT test were reliable across different RPE intensities and relative time points.
• Oxygen consumption, heart rate, ventilation, and speed showed no significant differences when expressed as relative durations (30%, 60%, 90%) of an effort.

Conclusions:

• The RABIT test is a valid and reliable method for assessing maximal oxygen consumption in recreational runners.
• The findings support the use of the RABIT test for establishing personalized submaximal and maximal training zones.
• This field test provides a practical tool for recreational runners to optimize their training strategies.
