Diurnal hormonal responses in exercise and sports medicine research: range effect adjustments

The paper discusses the means in which exercise hormonal data are transformed and expressed as a way to deal with the inherent variability in endocrine measurements. Specifically, the aim of the paper is to present an alterative transformation adjustment method for expressing the exercise responses of hormones, especially those which exhibit a diurnal behaviour in their circulating concentrations. The suggested alterative adjustment method attempts to account for the influence of the "range effect" on diurnal hormonal data and the subsequent effects it may have on statistical, and perhaps physiological, outcomes and data interpretation.
