Table 3 Change from Test 1 to Test 2 in functional impairment classification using VO 2 peak and ventilatory threshold criteria[34]
VO2peak(ml.kg-1.min-1) | Number of classes decreased (# participants) | |
|---|---|---|
A (>20) | -1 class (N = 5)* | |
B (16–20) | -1 (2) | -2 (1) |
C (10–15) | ||
D (<10) | ||
Ventilatory threshold (ml . kg -1. min -1 ) | ||
A (>14) | -1 (2) | -2 (2) |
B (12–14) | -1 (3) | -2 (1) |
C (9–10) | -1 (4) | |
D (6–7) | ||
Number of participants whose impairment classification decreased on Test 2 based on criteria of VO2peak, VT, or both VO2peak and VT | ||
VO 2 peak only | VT only | VO 2 peak & VT |
