“…Thus, the higher values of torso flexors and extensors in adult female volleyball players [7] might be attributed to a long-term training effect. Moreover, low back pain was associated with torso extensors and flexors weakness [36]. With regard to the normal group, i.e., the group with torso flexors-to-extensors ratio lower than one, it was observed that this ratio (0.49) was lower than that reported by literature on healthy adults and adult female volleyball players (~0.72) [7,16].…”

The aim of the present study was to examine the variation in core stability and symmetry of youth female volleyball players by age, and its relationship with anthropometric characteristics, the 30 s Wingate anaerobic test (WAnT), and the 30 s Bosco test. Female volleyball players (n = 24, age 13.9 ± 1.9 years, mean ± standard deviation) performed a series of anthropometric, core stability tests (isometric muscle endurance of torso flexors, extensors, and right and left lateral bridge), WAnT (peak power, mean power, Pmean, and fatigue index, FI) and Bosco test (Pmean). Flexors-to-extensors ratio and right-to-left lateral bridge ratio were also calculated. Participants were grouped into younger (n = 12, 12.3 ± 1.2 years) or older than 14 years (n = 12, 15.4 ± 1.0 years), and into normal (flexors-to-extensors ratio < 1; n = 17) or abnormal flexors-to-extensors ratio (≥1; n = 7). The older age group was heavier (+11.3 kg, mean difference; 95% CI, 2.0, 20.6) and with higher body mass index (+2.8 kg m−2; 95% CI, 0.4, 5.1) than the younger age group. The group with abnormal flexors/extensors had larger flexors muscle endurance (+77.4 s; 95% CI, 41.8, 113.0) and higher flexors/extensors ratio (+0.85; 95% CI, 0.61, 1.10) than the normal group. Body fat percentage (BF) correlated moderately-to-largely with flexors (r = −0.44, p = 0.033), extensors (r = −0.51, p = 0.011), and left lateral bridge (r = −0.45, p = 0.027); WAnT Pmean moderately-to-largely with right (r = 0.46, p = 0.027) and left lateral bridge (r = 0.55, p = 0.006); FI moderately-to-largely with right (r = −0.45, p = 0.031) and left lateral bridge (r = −0.67, p < 0.001), and right/left ratio (r = 0.42, p = 0.046); Bosco Pmean correlated moderately-to-largely with right (r = 0.48, p = 0.020) and left lateral bridge (r = 0.67, p = 0.001). A stepwise regression analysis indicated FI and BF as the most frequent predictors of core stability. The findings of the present study suggested that increased core stability was related to decreased BF and increased anaerobic capacity. A potential misbalance between torso flexors and extensors might be attributed to bidirectional variations (either high or low scores) of flexors muscle endurance rather than decreased extensors muscle endurance.

“…But often, this reorganization is inadequate overloading the subsystems, promoting a chronic spinal dysfunction-instability. (3,4) The spinal stabilization incapacity caused by the imbalance between the function of the extensor and flexor muscles of the trunk is a strong clue to the development of low back pain.

Introduction:The thoracolumbar musculature plays a key role in the balance and stability of the pelvis. The isokinetic dynamometer provides accurate assessment of muscle performance and treatment guidance. Objective: To compare the flexors / extensors of the trunk link between sedentary men and women, asymptomatic by isokinetic dynamometry. Method: An observational cross-sectional study. The sample consisted of 100 asymptomatic sedentary volunteers, 50 males and 50 females with a mean age of 22.2 ± 3.3 years. The collection was made in the center of isokinetic dynamometry of the university grew. The Cybex Norm isokinetic dynamometer Model 7000 ™, trunk module was used. The subjects were weighed and measured, made global warming a 5 minutes cycle ergometer unloaded. Tested the flexor and extensor muscles in concentric and eccentric contractions, with an interval of three minutes between each assessment. We adopted a range of 10 degrees of extension to 70 degrees of flexion, with five repetitions at angular velocity 60 ͨ / s performing maximal strength. Familiarity with the equipment was done in the way of submaximal intensity contraction. The analysis was performed using SPSS, version 20.0 (p <0.05). Results: muscle ratio for females was higher compared to males, demonstrating in men greater deficit flexors compared to extensors of the trunk. Conclusion: no significant neither for females nor for males difference. Confirming that the ratio of muscle strength agonist/antagonist of a joint should not change regardless of the mode of contraction is tested.

“…Low fitness in the modified push-up test has been associated with poor perceived health, low back dysfunction, and pain among middleaged subjects [49]. Also, poor endurance in the back musculature has been reported to be a risk factor for low back pain [14,50]. The modified push up test requires endurance of the back muscles for trunk stabilisation.…”
