Using a logarithmic regression to identify the heart-rate threshold in cyclists.

The purpose of this study was to establish an objective method for identifying the heart-rate threshold (HRT) in cyclists. Fifty-six male cyclists were tested on a cycle ergometer to volitional fatigue. Identification of the HRT used a heart-rate increase above a logarithmic regression line of best fit, coupled with the crossover of a linear regression line of best fit.

The accuracy of self-reported smoking status assessed by cotinine test strips.
