description <p dir="ltr">An index of heart rate variability (HRV), detrended fluctuation analysis (DFA a1) has gathered interest as a surrogate marker of exercise intensity boundaries. The aim of this report was to examine heart rate variability threshold (HRVT) behavior across different ramp incremental (RI) slopes. Seventeen participants completed a series of three RI (15, 30, and 45 W · min<sup>−1</sup> slopes) with monitoring of gas exchange parameters, heart rate (HR) and HRV. HRVT1 was defined as the V̇O<sub>2 </sub>or HR at which DFA a1 reached 0.75 and the HRVT2 at which these values reached 0.5. HRVTs were compared by Pearson's r, Bland–Altman analysis, <sub>ICC3</sub>,<sub>1</sub>, ANOVA, and paired t‐testing. An excellent degree of reliability was seen across all three ramps, with an <sub>ICC3,1</sub> of 0.93 and 0.88 for the HRVT1 V̇O<sub>2</sub> and HR, respectively, and 0.90 and 0.92 for the HRVT2 V̇O<sub>2</sub> and HR, respectively. Correlations between HRVT1/2 of the individual ramps were high with r values 0.84–0.95 for both HR and V̇O<sub>2</sub>. Bland–Altman differences ranged between −1.4 and 1.2 mL · kg<sup>−1</sup> · min<sup>−1</sup> and −2 and +2 bpm. Paired t‐testing showed no mean differences between any HRVT1/2 ramp comparisons. Cycling ramp slope does not appear to affect either HRVT1 or HRVT2 in terms of HR or V̇O<sub>2</sub>.</p><h2>Other Information</h2><p dir="ltr">Published in: Physiological Reports<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.14814/phy2.15782" target="_blank">https://dx.doi.org/10.14814/phy2.15782</a></p>
