Washington, Sept 14 (ANI): A new study has confirmed that the low-tech, easy-to-administer test called the "Talk Test" is an effective tool for gauging exercise intensity, but that it does not compare as well as previously assumed to other more objective tests.
University of New Hampshire associate professor of kinesiology Timothy Quinn and his former graduate student Benjamin Coons set out to learn just how good this test, gaining in popularity over the past decade, is, and how it compared to two other laboratory-tested measures of intensity, the lactate threshold and the ventilatory threshold.
They found that when participants reported a positive Talk Test - that they could still speak comfortably - they were exercising at the lower end of established exercise intensity guidelines as measured by both heart rate and maximal oxygen consumption, or VO2 max.
When participants became uncertain that they could still speak comfortably, they were exercising at the upper end of intensity guidelines.
This finding confirmed the effectiveness of the Talk Test.
More surprising, however, was how the Talk Test compared to the lactate threshold, the point at which muscles can no longer metabolise and remove lactic acid as it builds during exercise, and the ventilatory threshold, which is characterized by sudden heavy breathing.
Data showed that the Talk Test related best to the lactate threshold as compared to the ventilatory threshold
"Everybody's thought that the Talk Test related well to the ventilatory threshold," Quinn stated.
"And it does, to a certain degree. But different physiological phenomena occur at each threshold, and it is the phenomena associated with the lactate threshold that relate better to the different levels of the Talk Test," he added.
The study has been published recently in the Journal of Sports Sciences. (ANI)
