The objective of this study was to evaluate varia tion in the lumbar spine extension (LSE) muscular strength index and the hydroxyproline (HP) urinary concen - trations as a function of flexibility training with maxi mum intensity (flexibilizing) statically, by proprioceptive neuro - muscular facilitation (PNF) and submaximally. The sample
population – with an age of 17.13 ± 1.23; body mass of 63.23 ± 6.36 kg; height of 173.62 ± 5.465 cm and body fat percentage of 10 ± 3.62% – comprised 60 male individuals divided randomly into four equal groups: CG (control), StrG (stretching), SFG (static flexibilizing) and PNFG (flexibilizing by PNF). The statistical program SPSS 14.0 for Windows was used to perform a Shapiro Wilk test to verify the normality of the data and Levene’s test to analyze the homogeneity of the sample, repeated measu - res ANOVA for multiple compa risons among groups and the Tukey’s HSD Post Hoc test to determine the statistical difference within groups of the variables. A significance
level of 95% (p<0.05) was adopted. The results showed a significant difference in LSE between PNFG and CG (D% = 11%; p = 0.029). It can be concluded that the practice of
PNF increased strength in the study group.
