Influência aguda da prática de Mindfulness sobre as variáveis associadas à potência aeróbia: ensaio clínico, autocontrolado e randomizado

Abstract

Objective: To verify the acute influence of the practice of Mindfulness (MF) on the variables associated with aerobic power (VO2max. and vVO2max.). Methodology: 15 male volunteers aged between 18 and 30 years were selected. In a random and selfcontrolled way, the participants were allocated to the experimental (MF) and control (CT) situations. In both situations, they answered the Brums and MAAS questionnaires and participated in the continuous and incremental effort test until exhaustion, performed on a treadmill for the indirect determination of VO2max, vVO2max and velocity related to 80% of vVO2max, in addition to heart rate and perception effort rating, measured during the test. Results: Through a t test for paired samples with a significance level of 5%, it was verified that the variables: VO2max in absolute values (CT = 3.65 ± 0.55 L/min and MF = 3.60 ± 0 .54 L/min), VO2max in relative values (CT = 50.60 ± 4.66 ml/kg/min and MF = 49.90 ± 4.88 ml/kg/min), vVO2max (CT = 13.90 ± 1.38 km/h and MF = 13.60 ± 1.45 km/h) and v80% (CT = 11.10 ± 1.11 km/h and MF = 10.90 ± 1.16 km/h), were statistically lower for the MF situation compared to the CT. Conclusion: It is concluded that the acute practice of MF negatively influenced the variables associated with aerobic power determined in the exercise test.
