“…For this reason, it is essential applying programs that pursue flexibility development and maintenance during early age to avoid this descent [2][3][4]. Many investigations have revealed muscle shortening in school age, especially in the hamstrings [3,[5][6][7][8] which is mainly caused for the adoption of bad postural habits and the increase in sedentary behaviour [9]. The decrease in hamstring muscle length has been associated with muscle damage [10], a decrease in the mobility of the pelvis [11], alterations in the lumbar-pelvic rhythm [12,13], appearance of other diseases such as low back pain [14], spondylolysis [15], spondylolisthesis, Scheuermann disease, herniated discs even of the lumbosacral region [16].…”

The main purpose of the present review was to examine the scientific literature on the effects of physical education-based stretching programs on hamstring extensibility in schoolchildren aged 6-11 years. For this purpose relevant studies were searched from ten electronic databases dated up through May 2015. Of the 25 potentially relevant articles identified and retrieved for more detailed evaluation, only eight studies were included in the present review because they met the inclusion criteria. The overall results showed that incorporating hamstring stretching as a part of physical education classes produces a significant improvement in the scores of the tests: straight leg raise and classic sit-and-reach, for the experimental groups, but not for control groups. Stretching programs can be included in Physical Education classes, specifically during the warmup and the cool down periods in order to improve hamstring extensibility. Although it seems that the stretching exercises in the warm-up period could be less effective in gaining flexibility in school children. Studies that use a stretching volume between 4 and 7 minutes per session and 2-4 training classes per week, obtain statistically significant improvements on the levels of hamstring flexibility in the experimental groups. However, after a five-week detraining period, children revert back to their initial flexibility levels. Therefore, it seems appropriate that physical education teachers should implement stretching programs to improve the students´ flexibility during the Physical Education classes. Key words:Hamstring stretching, primary students, stretching program, review. RezumatScopul principal al acesteirecenzii a fost de a examina literatura de specialitate cu privire la efectele programelor de stretching asupra extensibilității mușchilor ischiogambieri la elevii cu vârste cuprinse între 6-11 ani. În acest scop, au fost cercetate studii relevante din zece baze de date electronice datate până în mai 2015. Din cele 25 de articole potențial relevante identificate și extrase pentru o evaluare mai detaliată, doar opt studii au îndeplinit criteriile de includere înaceastă recenzie. Rezultatele globale au arătat că includerea exercițiilor de stretching pentru mușchii ischiogambieri în cadrul orelor de educație fizică determină o îmbunătățire semnificativă a testelorLasègue și sit-and-reach, pentru loturile experimentale, dar nu și pentru cele de control. Programele de stretching pot fi incluse în orele de educație fizică, în special în timpul perioadelor de încălzire și relaxare cu scopul de a îmbunătăți extensibilitatea mușchilor ischiogambieri. Totuși, se pare că exercițiile de stretching efectuate în perioada de încălzire sunt mai puțin eficace în creșterea flexibilității la copiii de școală. Studiile care utilizează 2-4 sesiuni de antrenament pe săptămână cu durata între 4 și 7 minute pe sesiune, au obținut îmbunătățiri semnificative statistic ale flexibilității mușchilor ischiogambieri din grupele experimentale. Cu toate acestea, după o perio...

“…For instance, Kanásová (2008) found a high prevalence (up to 89%) of shortened hamstring muscles in 10-to-12-year-old students. In the study by Rodríguez et al (1999), the data obtained in the previous test indicated that 77% of adolescents were within normal limits, while 23% suffered from shortness.…”

“…Because of the high prevalence of physical inactivity, sedentary behaviours and bad postures, cases of muscle tension and shortenings increase considerably in children (Kanásová, 2008;Penha & Amado Joäo, 2008) and adolescents (Vidal, Vidal, Almela, & Vidal, 2011;Huang & Malina, 2007).…”

El objetivo principal del presente estudio fue examinar los niveles de extensibilidad isquiosural de los estudiantes durante un curso académico. Una muestra de 128 estudiantes de 1º de bachillerato de un centro de educación secundaria se evaluó mediante la prueba de classic sit-and-reach al comienzo, mediados y final del curso académico. Los resultados mostraron que el nivel de extensibilidad de isquiosural de los estudiantes disminuyó estadísticamente significativamente desde el comienzo (22,1 ± 8,5 cm) a mediados (19,9 ± 8,6 cm, d = -0,26) y final del año académico (18,6 ± 9,3 cm; d = -0,41) (p < 0,001), y desde mediados al final (d = -0.16) (p < 0,001). Los resultados de la prueba de McNemar indicaron que hubo una disminución estadísticamente significativa en la proporción de estudiantes con un nivel de extensibilidad isquiosural normal desde el comienzo al final del curso académico (p < 0,05). En conclusión, los estudiantes de educación secundaria perdieron niveles de extensibilidad isquiosural durante un curso académico. Como resultado de esta disminución, el número de estudiantes con acortamiento de los músculos isquiosurales aumentó un 10,9%. Los profesores de educación física deberían implementar programas de estiramiento para prevenir el acortamiento de extensibilidad isquiosural de los estudiantes.

“…In this line, previous studies found that stretching training programs develop hamstring extensibility among children (Coledam, Arruda, & Ramos de Oliveira, 2012;Rodríguez et al, 1999;Rodríguez, Santonja, López-Miñarro, Sáinz de Baranda, & Yuste, 2008;Sainz de Baranda et al, 2006;Santonja, Sainz de Baranda, Rodríguez, López, & Canteras, 2007). Therefore, physical activity programs for children such as physical education or organized recreational sports should develop hamstring extensibility (Kanásová, 2008;Sainz de Baranda et al, 2006;Santonja et al, 2007).…”

Abstract:The objective of the present study was to determine the effects of a short-term stretching training program followed by five weeks of detraining on hamstring extensibility among children aged 9-10 years. A total of 45 children aged 9-10 years, 24 boys and 21 girls, participated in the present study. Participants were clustered randomly assigned to a stretching group (n = 22) or a control group (n = 23). Hamstring extensibility was estimated by the classic sit-and-reach test, which it was applied at the beginning and at the end of the stretching training program, as well as after five weeks of stretching detraining. The stretching group participants performed a five-minute stretching training program twice a week for eight weeks. Afterward, these stretching group children underwent a detraining period of five weeks. The results of the two-way ANOVA showed that the stretching training program significantly increased the children´s hamstring extensibility (p < 0.001). Nevertheless, after five weeks of stretching detraining, the flexibility levels reverted back to the baseline. For the control group participants no statistically significant differences were found (p > 0.05). The most important contribution of the present study was to test that after five weeks of stretching detraining children´s flexibility reverts back to its baseline level. Therefore, because physical activity programs for children are frequently interrupted by various vacations, children should be encouraged to continue training their flexibility during these periods.
