Sample and participant characterization by groups. Porto Alegre, Rio Grande do Sul, Brazil, 2023
CBKF
Média/desvio padrão (Teste t); n/% (Qui-Quadrado)The non-observance of a statistically significant difference between groups is highlighted, characterizing homogeneity in the sample.The analysis of IG and CG means showed that there was no statistically significant difference in OSL between groups (IG 2.0±0.1; CG 2.2±0.1; p= 0.356) and between sessions (D0 2.3±0.8; D8 2.1±0.8; p=0.823). Comparison of means between groups versus sessions showed a reduction in the OSL value in IG and CG, but with no statistically significant difference (IGD0 2.2±0.8; IGD8 2.1±0.8; CGD0 2.3±0.8; CGD8 2.0±0.8; p=0.531).As for WRSS, there was no statistically significant difference in the effect of groups (IG 1.8±0.8; CG 1.9±0.8; p=0.542) and between sessions (D0 1.9±0.7; D8 1.8±0.7; p=0.199). In the groups versus sessions effect, there was a reduction in the mean of D8 in IG and CG, when compared to D0, however without statistically significant difference (IG D0 1.9±0.7; IGD8 1.7±0.8; CGD0 1.9±0.7; CGD8 1.8±0.6; p=0.169). According to the three GHG effect models, it was verified that CBKF did not present a statistically significant result in the OSL and WRSS instruments (p>0.05).The comparison of the means of HRV indicators in the effect of groups, according to GEE, showed a statistically significant difference in SDNN (IG 73.1±4.0; 59.3±4.0; p=0.016), LF/HF ratio (IG 7.6±0.6; CG 1.6±0.2; p<0.001) and cardiac coherence (IG 60.4±1.8; CG 34.1±0.8; p<0.001). In rMSSD, however, there was no statistically significant difference between groups (IG 65.7±5.7; CG 65.4±5.9; p=0.974).In the effect of time (sessions), there is a statistically significant difference in SDNN (D0 53.9±2.9; D8 71.4±5.4; p=0.016), LF/HF ratio (D0 2.2±0.3; D8 3.3±0.3; p=0.008), cardiac coherence (D0 39.9±1.3; D8 46.6±1.3; p<0.001) and rMSSD D0 55.7±4.9; D8 72.8±7.7; p=0.007).
