* Protein carbonyl groups in trained subjects before and after a cardiopulmonary test.

- Physical exercise influences the body's oxidative status. The modifications can involve lipids, proteins and nucleic acids, and different effects seem to be induced by regular and acute exercise respectively. We examined protein oxidation, expressed as concentration of protein carbonyl groups (PC), in trained subjects before (time 0), 10 min (time 1) and 24 hours (time 2) after a cardiopulmonary test performed on a cycloergometer. We enrolled 38 trained subjects (26 men and 12 women), subdivided in two groups (A1 and B1) of 19 subjects each, according to the median value of VO2max, and in two groups (A2 and B2) of 19 subjects each, according to the median value of PC at baseline. PC concentration was measured by an enzyme-linked immunosorbent assay (ELISA). The groups A1 and B1 did not differ from each other as regards the basal PC level and groups A2 and B2 were not different as regards the VO2max. At time 1 PC showed a significant increase in comparison with baseline in trained subjects as a whole group, as well as in each subgroup. At time 2, PC were decreased in comparison with both times 0 and 1 in the whole group and in subgroups A1 and B2, whereas in subgroups A2 and B1 the PC value at time 2 was not different compared to time 0. The percentage increase of PC at time 1 vs time 0, as well as the percentage decrease at time 2 vs time 1 and time 0 respectively, were not different between subgroups A1 and B1. On the contrary, the percentage variations observed at each interval were significantly different between subgroups A2 and B2. The results suggest a reaction of antioxidant systems to acute exercise in trained subjects, influenced by basal PC levels more than by aerobic fitness.
