The Talk Test as a measure of exercise intensity in children

The Talk Test (TT), used to prescribe exercise intensity based on subjective measurements, has been widely studied, but never in children. This study evaluated the relationship between the TT and physiological changes, to determine if the TT is an appropriate measurement of exercise intensity in children. Thirteen healthy children were recruited for this study. The first exercise test was the TT, in which subjects read a passage containing over 100 words, and responded whether they could speak comfortably. The second test measured the maximal exercise capacity while also measuring gas exchange, which was used to identify each subject’s ventilatory threshold (VT). Results from the last positive (LP), equivocal (EQ), and negative (NEG) stages of the TT were compared to the subject’s VT. There were significant differences (p
