Kerr, G., VanHeest, J. L., & Rodgers, C. D. (1998). Changes in psychological and biochemical indices of stress across a competitive season in age-group swimmers. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 502.

Age group swimmers (M = 18; f = 12) were assessed at various stages of a competitive season for psychological stresses (Daily analyses of Life Demands for Athletes) and on biochemical factors (salivary IgA and cortisol levels).

Over a five month period there was no difference in the sources of perceived stress, but significant increase in the number of stress symptoms and cortisol levels and a decrease in salivary IgA levels.

Implication. Changes in biochemical indices of stress may be associated with increased reports of symptoms of stress and decline in general health.
