The association of aerobic and strength exercises in the same training session is called concurrent training (CT). Despite the common use of this kind of training, there are evidences that this combination could cause reduction in the performance of the strength activity, although studies using different protocols and participants with different training backgrounds presented different results. Thus, the present study has the objective to analyze the effect of the time of recovery between a high intensity aerobic activity followed by a strength exercise in the capacity of producing strength, in subjects with different training status. The participants (n=30) will be separated in three groups according to their status of training (aerobic, strength and concurrent), and will be submitted to three sessions to determine: (1) the velocity correspondent to VO2max (VVO2max); (2) 1 repetition maximum (1RM) load in the leg press exercise; (3) control session (CS) strength resistance (maximal number of repetitions at 80% of 1RM). Subsequently, they will be submitted to five randomized experimental sessions. Each session will begin with 30 minutes of intermittent aerobic exercise (100% of VVO2máx - 1x1 minute) followed for a CS altering the time of recovery between the activities (30, 60 minutes, 4, 8 and 24 hours). The comparison will be done through two factors (group and time) with repeated measures in the second factor. When a significant difference (p<0.05) is found a Tukey test will be conducted.
