From: Effect of rest duration between sets on fatigue and recovery after short intense plyometric exercise

Changes in ammonia levels (μmol/l) before exercise (pre) and in the successive 7 measurements taken every 5 min after exercise. The arrows indicate the range of measurements in which ammonia concentration remained significantly higher (p < 0.001) than pre-exercise. *p < 0.05, **p < 0.01, ***p < 0.001—values significantly higher than pre-exercise. ap < 0.05—values significantly higher than in groups G45 and G90.
