Oxygen consumption (VO₂) during treadmill-exercise in relation to % increased plasma endostatin. The peak speed and the time spent at peak speed on the treadmill were 4.85 ± 0.99 (mean ± SD) miles per hour and 6.86 ± 2.76 minutes (n = 7; ranging 4–10 min), respectively. The total peak VO₂ was considered as the product of peak VO₂ and the time spent running at that peak. The % increased plasma endostatin after exercise ranged from 30% to 300% for different individual. There was a strong linear correlation between % increase in plasma levels of endostatin and the total peak VO₂ (R = 0.969; R² = 0.9388; P < 0.01).
