“…Studies that examined the effect of muscular training programs on posture in adolescents are sparse. Interrelationships between muscle strength and posture parameters were found by Barczyk-Pawelec et al (2015) , but they did not examine the direct influence of muscle strength on posture. Kim et al (2006) found that an imbalance in trunk muscle strength could influence lumbar lordosis, which they assume to be a risk factor for low back pain.…”

Poor posture in childhood and adolescence is held responsible for the occurrence of associated disorders in adult age. This study aimed to verify whether body posture in adolescence can be enhanced through the improvement of neuromuscular performance, attained by means of targeted strength, stretch, and body perception training, and whether any such improvement might also transition into adulthood. From a total of 84 volunteers, the posture development of 67 adolescents was checked annually between the age of 14 and 20 based on index values in three posture situations. 28 adolescents exercised twice a week for about 2 h up to the age of 18, 24 adolescents exercised continually up to the age of 20. Both groups practiced other additional sports for about 1.8 h/week. Fifteen persons served as a non-exercising control group, practicing optional sports of about 1.8 h/week until the age of 18, after that for 0.9 h/week. Group allocation was not random, but depended on the participants’ choice. A linear mixed model was used to analyze the development of posture indexes among the groups and over time and the possible influence of anthropometric parameters (weight, size), of optional athletic activity and of sedentary behavior. The post hoc pairwise comparison was performed applying the Scheffé test. The significance level was set at 0.05. The group that exercised continually (TR20) exhibited a significant posture parameter improvement in all posture situations from the 2nd year of exercising on. The group that terminated their training when reaching adulthood (TR18) retained some improvements, such as conscious straightening of the body posture. In other posture situations (habitual, closed eyes), their posture results declined again from age 18. The effect sizes determined were between η2 = 0.12 and η2 = 0.19 and represent moderate to strong effects. The control group did not exhibit any differences. Anthropometric parameters, additional athletic activities and sedentary behavior did not influence the posture parameters significantly. An additional athletic training of 2 h per week including elements for improved body perception seems to have the potential to improve body posture in symptom free male adolescents and young adults.

“…Among male students, an association was observed between thoracic hyperkyphosis and failure to maintain spinal curvatures in sitting posture and pelvis changes in 6 and 9 min, in addition to the factor of the distant position of the table in 9 min. Thus, the posture assumed by the students seems to be the result of several factors, among them the ergonomics of the school chair-table object [27,28] and may not satisfy the objective for which it is intended, and such fact, sometimes, may not meet the recommendations of the Brazilian Regulatory Standard-NBR, which standardized school furniture in Brazil (ABNT NBR 14006) [29].…”

ObjectivesTo investigate the association between sitting posture during the use of school furniture and changes in the spine in adolescents.MethodsA cross-sectional study was conducted with 240 students. The sitting position on school furniture was collected five times (3, 6, 9, 12, and 15 min). Postural alteration of the spine was identified by direct observation in front of a symmetograph. Screening for scoliosis was obtained by Adams test.ResultsThe presence of the factor away from the table presented higher percentages at times 3, 6, 9, and 15 min (24.2, 25, 29.2, and 26.7%, respectively). At 12 min, the highest frequency was the presence of poorly positioned lower limbs (25.8%). Associations were observed between poor sitting posture with changes in head anteriorization and retroversion of the pelvis among women and with thoracic hyperkyphosis in men.ConclusionsThe findings suggest that there are sex-dependent associations between poor sitting posture during use of school furniture and spinal alterations in adolescents.

“…There are thoracolumbar extensors and iliopsoas together with rectus femoris in the shortened and tight muscle group, and abdominals together with gluteus medius and maximus on the weak group [5]. Poor posture is also related to a lower value in isokinetic strength of the trunk muscle [6] and also to a lower endurance capacity of trunk muscles, especially for hyper-lordotic spine [4]. But we cannot fi nd studies describing the ratios of muscle strength and grouping that assess the size of differences between the agonists and antagonists according to the impact on deviations in the posture.…”
