Physiological Responses During High-Intensity Interval Training in Young Swimmers.

ABSTRACT: This study analyzed whether 100- and 200-m interval training (IT) in swimming differed regarding temporal, perceptual, and physiological responses. The IT was performed at maximal aerobic velocity (MAV) until exhaustion and time spent near to maximalVO₂ peak oxygen uptake (⩒O₂peak), total time limit (t_Lim), peak blood lactate [La^-] peak, ⩒O₂ kinetics (⩒O₂K), and rate of perceived exertion (RPE) were compared between protocols. Twelve swimmers (seven males 16.1 ± 1.1 and five females 14.2 ± 1 years) completed a discontinuous incremental step test for the second ventilatory threshold (VT₂), ⩒O₂peak, and MAV assessment. The swimmers subsequently completed two IT protocols at MAV with 100- and 200-m bouts t
