“…With regards to other macrophage functions assayed, both exercise groups showed increased H 2 O 2 production, conWrming previous studies with similar results (De La Fuente et al 1990, 1993Woods et al 1994;Ortega et al 1996;Sugiura et al 2001). These results indicate that exercise increases hydrogen peroxide production by peritoneal macrophages, independent of the exercise load, since rats from the MOD group were trained for 1 h, while exhaustively trained rats performed 3 £ 1-h sessions with 150 min of rest between sessions.…”

“…Increases in various functions of macrophages have been associated with moderate exercise (9,10,30). However, the increase in macrophage function following moderate exercise has not been shown to have a direct role in reducing susceptibility to URTI.…”

“…For example, exhaustive exercise has been shown to decrease macrophage antiviral resistance (7,8), antigen presentation (4), and antigenspecific cytokine response to induced URTI (16), as well as natural killer cell cytotoxicity (16). Moderate exercise has been associated with an increase in macrophage antiviral resistance (9), macrophage chemotaxis, adherence, oxidative metabolism and phagocytic activities (10,30), an enhanced antigen-specific cytokine response (17), as well as increased natural killer cell activity (27,39). However, there are no studies that directly test the specific role of any of these immune system alterations as mediators of exercise-induced changes in risk of infection.…”

“…When mice were subjected to a period of training exercise, we confirmed that this type of exercise induces a stimulation of phagocytic function in all experimental groups, in agreement with our previous results ( Ortega et al . 1992a , 1993b, De la Fuente et al . 1993 ) and with the results of other authors ( Northoff & Berg 1991) following other regimens of physical activity.…”

“…The mice of the second group, i.e. the training exercise (TE) group, were kept swimming under the above‐mentioned conditions 90 min each day during 20 days, a period of time that has been shown to influence macrophage functions ( De la Fuente et al . 1993 ).…”
