Figure 2

Comparison of percentage in the left subclavian vein (A), right subclavian vein (B), and the precordial region (C). Following ANCOVA, Bonferroni post hoc analysis was conducted to specify protocol effect. NWIG, no-water-intake group; 30WIG, 30%-water-intake group; 50WIG, 50%-water-intake group; 100WIG, 100%-water-intake group. The data are represented as mean ± SD. *, **, and *** represent p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001, respectively, when compared to NWIG at post-dive (post). #, ##, and ### represent p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001, respectively, when compared to NWIG at 30 min into recovery time (rec).
