TABLE 3.

Comparison of the set percentage below, within, and above the heart rate relative to the anaerobic threshold 2 (HR_AT2).

Group	% Of sets below, within, and above the HR_AT2
Group	<90%	90%–100%	100%–110%	>110%
G_N	16.6 (21.7)	41.8 (19.5)^a	36.1 (25.9)^a	5.5 (8.8)^bc
G_HR	14.7 (19.6)	46.7 (24.0)^a	32.1 (21.9)	6.5 (13.2)^bc
G_H	9.5 (14.2)	43.4 (19.4)^a	37.7 (18.9)^a	9.5 (13.8)^bc

G_N, group in normoxia; G_HR, group in hypoxia recovery; G_H, group in hypoxia. <90% = below HR_AT2; 90%–100% = within the proposed HR; >100% = above HR_AT2. ^a = p < 0.05 compared to <90%; ^b = p < 0.05 compared to 90%–100%; ^c = p < 0.05 compared to 100%–110%.
