Physiological Adaptations to High-Intensity Interval and Continuous Training in Kayak Athletes

This study compared physiological adaptations with HIIT and CT in flat water kayak athletes. Twenty-four national-class kayakists were divided into 3 groups (n = 8 per group), 2 of which participated in an 8-week CT or HIIT program, whereas the third one served as control (C). An incremental maximum oxygen uptake (V̇o2max), a maximal anaerobic Wingate-type, as well as 1,000-m (T1,000 m) and 200-m (T200 m) time test were performed before and after the training period on a kayak ergometer, to determine changes in V̇o2max, peak blood lactate ([La+2]peak), paddling speed at V̇o2max (JOURNAL/jscr/04.03/00124278-202008000-00020/20MM1/v/2020-07-23T111135Z/r/image-tiff), heart rate at V̇o2max (HRpeak), paddling economy speed (PEs; speed at 75% of V̇o2max), paddling speed at anaerobic ventilatory threshold (PSVT2), maximal paddling speed (PSpeak), and reduction of PSpeak (PSR). V̇o2max, [La+2]peak, HRpeak, and PSR did not change after the 8-week training compared with baseline in either training group (p> 0.05). However, significant changes were found in PSVT2 and T200 m (HIIT), JOURNAL/jscr/04.03/00124278-202008000-00020/20MM1/v/2020-07-23T111135Z/r/image-tiff, PEs, PSpeak, and T1,000 m (CT and HIIT) (p
