Evidence that the talk test can be used to regulate exercise intensity

Area of Science:

• Exercise Physiology
• Sports Science
• Training Methods

Background:

• The Talk Test (TT) is a recognized surrogate for ventilatory threshold.
• TT is a viable alternative for prescribing exercise intensity.
• Previous studies show TT responsiveness to physiological changes.

Purpose of the Study:

• To determine if the Talk Test (TT) can be independently used to regulate exercise training intensity.
• To assess the feasibility of using TT stages (Last Positive, Equivocal, Negative) for self-regulated training.

Main Methods:

• 16 physically active volunteers underwent an incremental exercise test to identify TT stages.
• Subjects performed 30-minute steady-state runs, regulating velocity based on desired TT response.
• Conventional exercise intensity markers (heart rate, lactate, RPE) were monitored.

Main Results:

• All subjects completed the Last Positive (LP) stage; 13/16 completed Equivocal (EQ), and 2/16 completed Negative (NEG).
• Physiological responses aligned with predicted levels for appropriate training intensity.
• LP stage matched training intensities for healthy adults and athlete recovery/long sessions.
• EQ and NEG stages corresponded to higher intensity training for athletes.

Conclusions:

• The Talk Test (TT) can be proactively used to guide exercise training intensity.
• TT serves as a primary method for controlling exercise intensity, correlating with physiological markers.
• Different TT stages offer specific training intensity recommendations for various populations and goals.
