Hydroxyproline Levels in Young Adults Undergoing Muscular Stretching and Neural Mobilization

Abstract

je neuralnoj mobilizaciji i{ija -tikusa tokom fleksije kuka uz ekstenziju kolena uz direktan, oscilatoran i naporan pokret tokom 60 sekundi. SSG izvodila je pasivno stati~ko istezanje, sastavljeno od odr`avanja polo `aja s velikom amplitudom, ne prelaze}i granice pokreta, za period naprezanja od ~etiri do {est sekundi. HP u urinu odre|en je na po~etku i 24 ~asa posle intervencije pomo}u kolo ri metrijske metode. Ponovljena merenja pomo}u ANOVA pokazala su zna~ajne poraste u NMG (d=7,38 mg/24h; p=0,0001) i SSG (Δ=3,47 mg/24h; p=0,002) i poraste u NMG (Δ%=118,89%) u pore|enju sa SSG (Δ%=118,89%) u pore|enju sa SSG (Δ%=60,32%; p=0,006) i CG (Δ%=-0,91%; p=0,0001). Rezultati ukazuju na to da je NMG radila s tenzijom izvan uobi~ajenih lukova amplitude artikularnog po kreta, {to je izazvalo restrukturaciju kolagena.Klju~ne re~i: amplituda artikulatornog pokreta, vezivno tkivo, hidroksiprolin Summary: This study aimed to assess the acute effect of stretching and neural mobilization on urinary hydroxy pro line (HP) levels in young adults. The sample, composed of physical therapy students from Teresina (PI), was divided into three groups: a neural mobilization group (NMG; n=15; age= 22±3 years; BMI=24.75±3.09); a static stretching group (SSG; n=15; age=23±4 years; BMI: 25±4.33) and a control group (CG; n=15; age: 24±4 years; BMI: 23.91±3.09). The NMG underwent neural mobilization of the sciatic nerve while engaged in hip flexion with knee extension in a direct, oscillatory and stre nuous manner for 60 seconds. The SSG performed passive static stretching, which consisted of the maintenance of a high amplitude posture, without exceeding the limits of the movement, for a period of tension ranging from four to six seconds. Urinary HP was evaluated at the baseline and 24 hours after the intervention using the colorimetric method. Repeated measures ANOVA showed significant intragroup increases in the NMG (Δ=7.38 mg/24h; p=0.0001) and the SSG (Δ=3.47 mg/24h; p=0.002) and inter-group increases in the NMG (Δ%=118.89%) when compared to the SSG (Δ%=60.32%; p=0.006) and the CG (Δ%= -0.91%; p=0.0001). These results indicate that the NMG worked with tension beyond the ordinary amplitude arches of articular movement, thus causing a restructuring of collagen.

Efecto Agudo Del Entrenamiento Máximo De Flexibilidad Sobre La Fuerza Muscular Y Los Niveles De Hidroxiprolina Urinaria en Jóvenes Adultos

“…Murguía et al(38) observaron altos niveles de HP en pacientes sometidos a ejercicios de flexión, que muestran aparición de lesiones en el tejido. A pesar de que difieren de las conclusiones de este estudio, estos datos son consistentes con los obtenidos por Rocha-Mafra et al(39), quienes observaron un aumento significativo en los niveles de HP de las mismas personas después de someterse a una sesión de flexión estática.…”
