“…However, in another study (12) it was found that the static flexibilizing did not cause any strength differences in acute training, unlike a study by Torres et al (13), with 30 individuals, which indicated a reduction in strength after static flexion. In another study (14), the static flexibilizing and PNF exercises were found to change the strength levels, which suggests that the training program to increase flexibility can result in an immediate decrease in strength, a fact that is not observed for HP (15).…”

Summary: The objective of this study was to evaluate varia tion in the lumbar spine extension (LSE) muscular strength index and the hydroxyproline (HP) urinary concentrations as a function of flexibility training with maxi mum intensity (flexibilizing) statically, by proprioceptive neuromuscular 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 measures 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.Keywords: muscle strength, hydroxyproline, muscle stret ching exercises List of non-standard abbreviations: LSE -lumbar spine extension; HP -hydroxyproline; SF -sta tic flexibilizing; CG -control group; PNF -proprio cep tive neuromuscular facilitation; PERFLEX -Perceived Exer tion Scale on Flexibility; SPSS -Statistical Package for So cial Science.Kratak sadr`aj: Cilj studije bio je da se odrede varijacije indeksa mi{i}ne snage ekstenzije lumbalnog dela ki~me i koncentracije hidroksiprolina u urinu kao funkcija ve`banja fleksibilnosti sa maksimalnim intenzitetom (fleksibilizacija) stati~no, proprioceptivnom neuromi{i}nom facilitacijom (PNF) i submaksimalno.

Statisti~ki program SPSS 14.0 za »Windows« kori{}en je za izvo|enje testa Shapiro-Wilk kako bi se utvrdila normalnost podataka i homogenost uzorka. Za ponovljena merenja kori{}ena je ANOVA sa vi{estrukim pore|enjima izme|u grupa a Tukeyjev HSD post hoc test za utvr|ivanje statisti~ke razlike u okviru grupa varijabli. Usvojen je nivo zna~ajnosti od 95 % (p<0,05). Rezultati pokazuju zna~ajnu razliku u ekstenziji lumbalnog dela ki~me izme|u PNFG i CG (D%=11%, p=0,029). Mo`e se zaklju~iti da je upra`njavanje PNF poja~alo snagu u prou~avanoj grupi.Klju~ne re~i: mi{i}na snaga, hidroksiprolin, ve`be za istezanje mi{i}a

“…Por otro lado, el trabajo lento o estático, que provoca una suficiente tensión sobre el órgano tendinoso de Golgi, ocasionará una inhibición de las motoneuronas volitivas (α), lo que produce pérdida de fuerza, fuerza explosiva y resistencia de fuerza hasta por una hora después de su ejecución (Galdino et al, 2005;Arruda et al, 2006;Cardozo, Torres, Dantas y Simão, 2006;Sharman, Cresswell y Riek, 2006;Torres, Conceição, Sampaio y Dantas, 2009;Vasconcellos, Salles, Junior, Mello y Dantas, 2012;Costa et al, 2014).…”

La flexibilidad es uno de los componentes que conforman el estado físico. Sin embargo, entre todos los componentes, sigue siendo uno de los menos estudiados. Analizar la cualidad física flexibilidad y sus respectivas metodologías de entrenamiento considerando su intensidad de trabajo. Se realizó una revisión de la literatura. La variación de las intensidades de entrenamiento de flexibilidad permite la realización de diferentes trabajos. Estiramiento para intensidades submáximas y Flexionamiento para intensidades máximas. El control de las intensidades de entrenamiento de flexibilidad es fundamental para el logro de una buena planificación y preparación física adecuada para el objetivo idealizado.

Acute effects of static stretching on muscle strength Study aim: To assess the effects of static passive maximal stretching on muscle performance in order to clarify the existing controversies. Material and methods: Two randomly selected groups of the Brazilian Air Force personnel were studied: experimental (n = 15), subjected to 3 bouts of static passive stretching exercises of wrist flexors and extensors (beyond a mild discomfort). Every bout lasted 10 s and was followed by a 30-s rest. The control group (n = 15) performed no exercises. Muscle strength was measured with a handgrip dynamometer before and 20 min after the test. Results: Subjects from the experimental group had the pre-exercise handgrip strength significantly higher than postexercise (by about 7%; p<0.01). No significant decrease was noted in the control group. Conclusions: Static passive stretching induces decreases in muscle strength.
