Table 2 Physiological parameters means (± SD) measured during trial, grouped by trial type

From: The effect of turmeric (Curcumin) supplementation on cytokine and inflammatory marker responses following 2 hours of endurance cycling

  Curcumin Placebo Control
Cortisol (nMol) 308 ± 200 (190–426) 266 ± 200 (148–384) 289 ± 228 (148–430)
C-Reactive protein (mg/l) 0.5 ± 0.3 (0.3-0.7) 0.9 ± 0.9 (0.4-1.4) 0.7 ± 0.6 (0.3-1.1)
Haematocrit (%) 43 ± 2 (42–44) 43 ± 3 (41–45) 43 ± 2 (42–43)
Haemoglobin (g/dl) 15.0 ± 0.7 (14.6-15.4) 14.0 ± 0.9 (13.5-14.5) 15.1 ± 0.8 (14.6-15.6)
WBC (10 9 /L) 10.1 ± 2.7 (8.5-11.7) 9.6 ± 2.5 (8.1-11.1) 10.4 ± 2.6 (8.8-12.0)
Neutrophil (%) 61.9 ± 9.8 (56.1-67.7) 61.4 ± 9.2 (56.0-66.8) 63.5 ± 9.5 (57.6-69.4)
  1. Confidence intervals 95% are also reported following each value.
  2. Parameters show no significant difference between trials. These parameters were measured only at the end of exercise. Cortisol and C - reactive protein were measured to investigate any possible effects from the active compound curcumin. Haematocrit & Haemoglobin were measured to ensure that the athletes were in similar hydration status, while white blood cell and neutrophil percentage were needed to confirm that the athlete was not suffering from an infection at the time of the trial.
