Psychophysiological characterization of different capoeira performances in experienced individuals: A randomized controlled trial.

The aim of this study was to characterize the psychophysiological demand in different capoeira performances. Eleven experienced capoeira practitioners underwent the following procedures in different days: 1) anamnesis and anthropometric measurements; 2) aerobic performance assessment; 3 to 5) performances of 90 seconds in three capoeira styles (Angola, Benguela and São Bento), which were performed in randomized controlled cross-over design. The psychophysiological demand was assessed through the heart rate (HR), R-R interval (RRi), blood pressure (BP), blood lactate ([Lac]), blood glucose ([Gluc]), rating perceived effort (RPE), feeling scale (FS) and perceived activation (PA). Descriptive statistics with mean and standard deviation was performed. A two-way repeated measures ANOVA with Bonferroni post-hoc test was used. The Angola demand was between 56-71% maximal HR with [Lac]PEAK: 6.9±2.9 mM, RPEPEAK: 10.0±2.2 pts and FS: 2.7±1.7 pts, while in the Benguela participants reached 64-85% maximal HR with [Lac]PEAK: 9.5±3.0 mM, RPEPEAK: 11.0±2.8 pts and FS: 2.1±1.6 pts and for São Bento between 69-102% maximal HR with [Lac]PEAK: 15.7±2.6 mM, RPEPEAK: 15.5±4.1 pts and FS: -0.8±3.0 pts. Interaction time*performance occurred to [Lac] (F = 42.157; p<0.001), HR (F = 12.154; p<0.001), RRi (F = 4.774; p<0.001), parasympathetic modulation-rMSSD (F = 3.189; p<0.01), [Gluc] (F = 2.152; p<0.05), RPE (F = 5.855; p<0.01), FS (F = 2.448; p<0.05) and PA (F = 3.893; p
