Aerobic exercise with different blood flow restriction pressure levels affect the mood state of military?

The aim of the study was to analyze the effect of aerobic exercise with different levels of blood flow restriction pressure on mood in military personnel. The sample consisted of 13 military men (age = 20.6 ± 2.2 years; body mass = 68.1 ± 7.7 kg; height = 1.69 ± 0.05 cm). The walking protocols with and without BFR were carried out over 18 minutes, as follows: a) CW+50%BFR - continuous treadmill walking (40% vVO2max) with 50% BFR; b) CW= continuous treadmill walking without BFR (40% vVO2max); c) CW+80%BFR= continuous treadmill walking (40% of vVO2max) with 80% BFR and d) CW+100%BFR= continuous treadmill walking (40% of vVO2max) with 100%BFR. Mood was measured using the Brunel scale (BRUMS) before exercise, immediately after exercise, 30 and 60 minutes after exercise. There was a significant reduction in the perception of vigor in the exercise protocols with BFR greater than in the CW protocol without BFR immediately after exercise (p< 0.05); b) there was a significant reduction in the perception of vigor up to 60 minutes in the exercise protocols with BFR (p< 0.005); c) there were significant increases in the perception of fatigue in the exercise protocols with BFR immediately after exercise (p< 0.005). We conclude that AE with different levels of BFR increases the perception of muscle fatigue and pain/discomfort immediately post-exercise, and sustains a reduction in the perception of vigor up to 60 minutes post-exercise when compared to the effects perceived with aerobic exercise without BFR.
