Anticipation of subsequent demanding exercise increases the expression of haem oxygenase-1 mRNA in human lymphocytes

Figures & data

Table I.  Summary of data from the between-subjects comparison and the within-subjects comparison of basal HO-1 mRNA expression in human lymphocytes and plasma cortisol concentration.

Comparison	Lymphocyte HO-1 mRNA (Au)	Plasma cortisol concentration (nmol/l)
Between-subjects
Half marathon	146 ± 53*	551 ± 160**
Rest	57 ± 24	396 ± 96
Within-subjects
Exercise	72 ± 21***	435 ± 111
Rest	56 ± 20	431 ± 92

Values are group means ± SD (N = 8 in each group). HO-1 mRNA is expressed relative to GAPDH in arbitrary units (Au). *Denotes a significant difference between the half marathon runners and resting subjects in HO-1 mRNA levels (t (14) = 4.312; P = 0.001; P < 0.01). **Denotes a significant difference between half marathon runners and resting subjects in plasma cortisol concentration (t (14) = 2.371; P = 0.033; P < 0.05). ***Denotes a significant difference between exercise and rest trials in HO-1 mRNA levels (t (7) = − 2.470; P = 0.043; P < 0.05).
