Increase of blood leucocytes induced by a dynamic exercise has been studied in 10 adult male subjects (age: 22 +/- 2 years; body weight 73 +/- 10 kg; VO2max: 54 +/- 8 ml O2/kg.min. The exercise consisted of a 20 minutes test on a cycle ergometer at a work rate eliciting a total energy expenditure roughly equal to 80% of the maximal aerobic power (80% VO2max). During exercise the absolute number of circulating leucocytes (n Leu) increased significantly toward a maximal value reached in most cases at the end of exercise. The maximal values of n Leu--expressed as percentage of n Leu measured at rest--in the different blood leucocyte types (monocytes:n Mono; granulocytes:n GR; natural killer cells:n NK) and lymphocyte subsets (lymphocytes:n LY; lymphocytes T:n T; lymphocytes B:n B; lymphocytes T helper:n T4; lymphocytes T suppressor:n T8)--were as follows:n Mono:240%; n GR:170%; n NK:490%; n LY:220%; n T:200%; n B:190%; n T4:140%; n T8:190%. With the exception of n GR, n Leu decreased during recovery at a rate depending on the leucocyte type. The n T4/n T8 ratio, equal to 1 at rest, was reduced by about 40% during exercise. This ratio rose after exercise and reached a value equal to that measured at rest after 20 minutes recovery. In agreement with FERRY (1989), we concluded that exercise is accompanied by a selective mobilization of the different leucocyte types. The magnitude of this phenomenon and the kinetics of n Leu recuperation depend on cell types.
