[Salivary immunoglobulin A (sIgA) kinetics in young adults with an average or excellent aerobic capacity before and after a cardiopulmonary graded exercise test].

Background: Aim: To compare the concentration of secretory immunoglobulin-A (sIgA) in young adults with average or excellent aerobic capacity before and after a cardiopulmonary graded exercise test.

Methods: Participants were nine apparently healthy physically active males (Mean age = 21.3 ± 2.

Reliability of the maximal oxygen uptake following two consecutive trials by indirect calorimetry.

Background: The maximal oxygen uptake (VO2máx) assessment by indirect calorimetry is the most reliable method to determine VO2máx, but when repeated tests are conducted, the results have been controversial.

Aim: To determine the reliability of the maximal oxygen uptake (VO2máx) in healthy adults following two consecutive trials with 10 min rest between trials using the Bruce protocol.

Methods: Participants were 6 males apparently healthy physically active (Mean age=23,4±1,3 years), who performed twice the Bruce protocol and after reaching their VO2máx in the first trial they stepped down the treadmill and rested seated on a chair during 10 min.
