| description | <h3>Purpose</h3><p dir="ltr">This study examined the effect of 3 and 6 weeks of intensity domain-based exercise training on VO<sub>2</sub> kinetics changes and their relationship with indices of performance.</p><h3>Methods</h3><p dir="ltr">Eighty-four young healthy participants (42 M, 42 F) were randomly assigned to six groups (14 participants each, age and sex-matched) consisting of: continuous cycling in the (1) moderate (MOD)-, (2) lower heavy (HVY1)-, and (3) upper heavy-intensity (HVY2)- domain; interval cycling in the (4) severe-intensity domain (i.e., high-intensity interval training (HIIT), or (5) extreme-intensity domain (i.e., sprint-interval training (SIT)); or (6) control (CON). Training participants completed two three-week phases of three supervised sessions per week, with physiological evaluations performed at PRE, MID and POST intervention. All training protocols, except SIT, were work-matched.</p><h3>Results</h3><p dir="ltr">There was a significant time effect for the time constant (τ VO<sub>2</sub> ) between PRE (31.6 ± 10.4 s) and MID (22.6 ± 6.9 s) (p < 0.05) and PRE and POST (21.8 ± 6.3 s) (p < 0.05), but no difference between MID and POST (p > 0.05) and no group or interaction effects (p > 0.05). There were no PRE to POST differences for CON (p < 0.05) in any variables. Despite significant increases in maximal VO<sub>2</sub> (VO<sub>2max</sub> ), estimated lactate threshold (θLT), maximal metabolic steady state (MMSS), and peak power output (PPO) for the intervention groups (p < 0.05), there were no significant correlations from PRE to MID or MID to POST between ΔτVO<sub>2</sub> and Δ V O<sub>2max</sub> (r=– 0.221, r = 0.119), ΔPPO (r= – 0.112, r= – 0.017), ΔθLT (r= 0.083, r = 0.142) and ΔMMSS (r= – 0.213, r = 0.049)(p > 0.05).</p><h3>Conclusion</h3><p dir="ltr">This study demonstrated that (i) the rapid speeding of VO<sub>2</sub> kinetics was not intensity-dependent; and (ii) changes in indices of performance were not significantly correlated with ΔτVO<sub>2</sub>.</p><h2>Other Information</h2><p dir="ltr">Published in: European Journal of Applied Physiology<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s00421-024-05674-1" target="_blank">https://dx.doi.org/10.1007/s00421-024-05674-1</a></p> |
