Introduction: The Talk Test has been shown to be an effective surrogate of standard methods of prescribing exercise training intensity, and is responsive to manipulations known to change physiologic function. It is not known if the Talk Test can be used as a control tool for regulating training intensity. Methods: Physically active volunteers (n=16) performed an incremental exercise test to identify stages of the Talk Test (LP-1, LP, EQ, NEG). In subsequent, randomly ordered, 30 min steady state runs, the running velocity was regulated by 'clamping' the TT stage desired, and conventional markers of exercise intensity (Heart Rate, Blood Lactate, Rating of Perceived Exertion) were monitored. Results: All subjects could complete the LP-1 and LP states, with 13 and 2 subjects able to complete the EQ and NEG stages, respectively. Physiologic responses were broadly within those predicted from the incremental exercise test, and within the range of physiologic responses appropriate for exercise training. The LP-1 and LP stages generally produced intensities compatible with training intensity in healthy adults, the EQ and NEG stages produced intensities compatible with training in athletes. Conclusion: The Talk Test can be used simply to control exercise training intensity.
