Fig 1 Cardiorespiratory variables for (A) Vo2, (B) cardiac output, (C) stroke volume, and (D) heart rate during peak and submaximal staged exercise in subjects with HIV. Data are mean ± SE. ∗ Significantly different from stage 4 (P<.05); † significantly different from stage 3 (P<.05); ‡ significantly different from stage 2 (P<.05); ∥ significantly different from stage 1 (P<.05); ∗∗ significantly different from rest (P<.05).
