—Associations of the slope or the intercept of the regression line between power and reciprocals of number of contractions with prefatigue peak power (slope: a, intercept: c) or neuromuscular fatigue resistance (slope: b, intercept: d) (n = 31). The slope and the intercept are considered to be similar to the curvature constant (fatigability constant) and the critical power (fatigue threshold) of the power–duration relationship, respectively. The data are presented as raw data, and the correlation coefficients were calculated using log-transformed values.
