The pre-pubertal age can be considered as the most important for prevention and treatment of postural deformity. Postural adjustments to maintain static and dynamic balance depend on the relationship between sensory input organs (captors) and the environment. Currently, there are three captors known: the eye, the vestibule and the soles of the feet. Postural insoles work as exteroceptors and aim to reorganize the muscle group's tone and influence the body posture by proprioceptive reflexes and subsequent correction. Besides the proprioceptive insoles, the Pilates method for spine treatment and postural deviations has been widely applied, and it presents great adhesion and good outcomes for school children and pre-teens. The baropodometric projection of the body center of pressure (COP) could be used in clinical practice as an evaluation tool in the treatment of postural dysfunctions and spinal deviations, through a baropodometer device, but little has been published about its clinical outcomes on everyday use. This study described the case of an 11 year old with pelvic deviation due to short leg length and the treatment chosen accordingly to a baropodometric evaluation, such as the use of postural insoles combined with Pilates sessions for 40 days. After this period, it was noted a better plantar surface and peak pressures distribution, as well as a more homogeneous weight bearing on both feet, which can induce improvements on postural behavior and prevents spinal injuries.
Thus, the present study sought to compare the muscular strengths of lower limbs in professional soccer and cycling athletes and gym participants, identifying the peak torque, total work, agonist/antagonist ratio and muscular power of each type of sport. As a hypothesis of this study, it is expected that the soccer group presents values superior to the other groups in the variables peak of torque and total work, and the cyclist group presents higher power and muscular relation in comparison to the evaluated groups. Material and methods Research characterizationThis observational cross-sectional case-study consists of pre-existing data collection in the Collucci Clinic Database and AbstractMuscular strength is a primary biomechanical property that allows for human movement and can be defined as the ability of the muscular tissue to develop maximum strength from a muscle or muscle group at a given speed. However, when applied to the sports practice, muscle strength becomes more extensive, it is currently used differently for each sports modality since muscle tissue can generate force in different conditions of movement and physical demands. This study aimed to analyze the muscular strength of lower limbs of professional soccer and cycling athletes comparing with individuals gym participants. Sixty male subjects were selected for a convenience sample aged 18 to 40 years. Participants were divided into groups of 20 individuals from their sports modalities, being: SG-Soccer group, CG-Cycling and GG-Gym, matched by age, weight, height, and BMI. The participants of this research performed an isokinetic evaluation of the knee region. The data obtained by the isokinetic analysis of the torque peak (N.m) total work (J), agonist/antagonist ratio (%) of the evaluated body segment were submitted to statistical analysis by the ANOVA test (p≤0.05) and Bonferroni test (p≤0.05). It was observed that at speeds of 60°/s and 180°/s there was a higher torque peak and total work for the SG and GG group with statistically significant values (p≤0.05), however, the agonist/antagonist ratio presented a higher relation for the CG group, the values were not significant (p≤0.05). In the multiple comparisons between the groups, it was observed that there was a difference in all groups evaluated (p≤0.05) at the speed of 60º/s (peak torque and total work) except for the group SG vs GG for flexor of the left knee. At the speed of 180º/s in torque peak was observed a significant difference (p0.05), except for SG and GG (bilateral flexors and extensors). The total work in 180º/s all groups there was difference (p≤0.05), except for CG vs GG (bilateral flexors) and the SG vs GG and GG vs CG (bilateral extensors). At speeds of 60º/s and 180º/s, the agonist/antagonist ratio was not significant for all groups evaluated. Thus, this study concludes that the SG group presented better values for all strength characteristics except for the agonist/antagonist ratio comparing from CG and GG group, followed for GG group.
