Table 4.

Correlations between individual serum levels of stress hormones and leukocyte deviations (% changes from baseline)

Hormone	Leukocyte	Time after exerc.(h) (hormones/leukoc.)	Correlation coeff. (r)	P value
Cortisol	Neutrophils	0/0 – TW1	-0.49	0.06
		0/0 – TW2	-0.32	0.21
	Lymphocytes	0/1 – TW1	-0.51	0.05
	Mixed cells	0/5 – TW1	-0.31	0.26
		0/5 – TW2	0.31	0.25
GH	Neutrophils	During/0 – TW1	0.56	0.025
		During/0 – TW2	0.76	0.001

The table shows correlations for the HT and NT groups taken together at various times after TW1 and TW2. All other correlations (e.g. cortisol at 5 min vs. lymphocytes 65 min after, r = -0.15; p = 0.57) were <0.3 or >-0.3.
