Abstract

This investigation examined physiological responses to shallow water exercise (SWE) and to a high-intensity interval SWE workout (HIISWE) in males (M, n=9) and females (F, n=9). Participants performed 5 X 5 min. SWE bouts (bts.) at ratings of perceived exertion (RPE) 9, 11, 13, 15 and 17 (Borg scale) and a maximal bout of SWE with metabolic, heart rate (HR), and blood lactate (BLa) responses monitored. The same measurements were performed during HIISWE (4 X 4-min bts., alternating 20-s “all-out” and 10-s rest). Peak oxygen uptake (V̇O2) and BLa were greater in M (3.6 ± 0.4 vs. 2.7 ± 0.3 l. min-1, 10.9 ± 1.3 vs. 8.1 ± 1.7 mM) (p2 and HR were not different among mins. 3, 4, and 5 of ea. SWE effort (p>0.05). Peak BLa for HIISWE was 11.1 ± 2.2 (M) and 9.2 ± 1.7 (F) mM (p
