Table 4 Changes in VO2max, HRmax and SpO2 at SL and high altitudes (mean ± SD, n = 12)
From: Soldiers’ load carriage performance in high mountains: a physiological study
Parameter | SL | HA1 | HA2 | Percentage of decrease (%) | ||
|---|---|---|---|---|---|---|
SL vs HA1 | SL vs HA2 | HA1 vs HA2 | ||||
VO2max (ml · min−1 · kg−1) | 52.6 ± 3.8 | 44.0 ± 5.7 | 37.3 ± 4.0 | 16.4* | 29.2* | 15.3* |
HRmax (beats · min−1) | 187.6 ± 10.0 | 176.3 ± 14.3 | 174.8 ± 15.4 | 6.0* | 6.8* | 0.9 |
