Abstract Purpose Pronounced differences in individual physiological adaptation may occur following various training mesocycles runners. Here we aimed to assess the changes performance and of recreational runners performing with different intensity, duration frequency. Methods Employing a randomized cross-over design, intra-individual responses [i.e., peak ( $${\dot{\text V}}{\text O}_{2 {\rm peak}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mover><mml:mtext>V</mml:mtext><mml:mo>˙</mml:mo></mml:mover><mml:msub><mml:mtext>O</mml:mtext><mml:mrow><mml:mn>2</mml:mn><mml:mi>peak</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math> ) submaximal submax}}$$ xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mover><mml:mtext>V</mml:mtext><mml:mo>˙</mml:mo></mml:mover><mml:msub><mml:mtext>O</mml:mtext><mml:mrow><mml:mn>2</mml:mn><mml:mi>submax</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math> oxygen uptake, velocity at lactate threshold s (V 2 , V 4 )] (time-to-exhaustion (TTE)) 13 who performed three 3-week sessions high-intensity interval (HIIT), high-volume low-intensity (HVLIT) or more but shorter HVLIT (high-frequency training; HFT) were assessed. Results 2, TTE not altered by HIIT, HFT p &gt; 0.05). improved same extent = 0.045) 0.02). The number moderately negative responders was higher HIIT (15.4%); (15.4%) than (7.6%). very positive (38.5%) (23%) (7.7%). 46% responded positively two mesocycles, while 23% did respond any. Conclusion On group level, none interventions TTE, . mean index indicated similar numbers positive, non-responders HFT, HIIT. These findings indicate that magnitude is highly no pattern apparent.
