O objetivo deste estudo foi analisar a produção científica brasileira sobre o Atletismo entre 1999 e 2013. Foram identificados 162 artigos, e selecionados 55 estudos que abordaram o Atletismo como temática principal do estudo. Destes, 43 artigos (78,2%) foram relacionados com a Biodinâmica do Movimento Humano e 12 (21,8%) com a Pedagogia do Movimento. Analisando os estudos selecionados (caraterização a posteriori das análises), 30,9% (17) correspondiam à pesquisas na área de fisiologia do exercício, 20% (11) a lesões no esporte, 10% (6) sobre biomecânica, 7,3% (4) a psicologia do esporte e 7,3% (4) a nutrição esportiva. As áreas com menos pesquisas foram o treinamento esportivo, a iniciação esportiva e a história/sociologia do esporte com 5,5% (3) cada uma. A pedagogia do esporte e do doping, ficaram com a menor proporção de estudos, sendo 3,6% (2) cada uma. Seis estudos não apresentavam uma única modalidade como foco central na investigação, outros 15 enfocaram corridas de fundo e meio-fundo, 8 em corridas de rua e maratonas, 7 em corridas de velocidade, 6 em atletismo paralímpico e, com menor percentual, as provas de salto horizontal, arremessos e lançamentos e o atletismo escolar que tiveram 1 estudo cada. Conclui-se que é importante considerar os critérios de avaliação dos cursos de Pós-Graduação adotados pela CAPES, pois no modo atual o sistema parece limitar a investigação na área da Pedagogia do Movimento. Necessita-se também qualificar a pesquisa sobre o Atletismo no Brasil e desenvolver pesquisas com melhor aporte metodológico (estudos longitudinais, de intervenção, de validação de métodos, de revisão de literatura e qualitativos) bem como melhorar a amostragem e diversificar as investigações em diferentes provas do Atletismo.

“…In normal gait, the heel touches down in the initial contact phase with a slight inversion (in the order of 3–4° [ 1 ]). In the loading response that follows, the body weight is shifted to the foot, the heel transitions to eversion, and pronation occurs in the midfoot area [ 2 ].…”

BackgroundPeroneus longus acts as a foot evertor and pronator, thus ensuring stability of the talocrural joint by curbing inversion movement of the rearfoot. Increased activation of the peroneus longus muscle in the stance phase could have a stabilising effect on the ankle joint. This study aimed to determine whether the activity of the peroneus longus muscle could be increased by the targeted use of a specially formed lateral pressure element in a customised orthopaedic insole.MethodsThis was a laboratory-based study that utilised a randomised crossover design. Thirty-four healthy participants walked along a walkway in neutral footwear wearing a control insole or a sensorimotor insole with a lateral pressure point adjacent to the tendon of the peroneus longus muscle. The electromyographic muscle activity of the peroneus longus and tibialis anterior muscles was measured using surface electromyography. Contact with the ground was recorded via two pressure sensors under the sole of the shoe. Muscle activity during the stance phase was analysed in the time and amplitude domains and compared statistically with paired t-tests for both insole types.ResultsIn 27 out of the 34 participants, an additional activity peak of the peroneus longus muscle was observed in the loading response phase with the sensorimotor insole, which reached its maximum at 29.7 % (±4.5 %) of the stance phase. When averaged over all 34 participants, the integrated electromyographic output for the peroneus longus in the mid-stance phase revealed a significant higher activity (p < 0.001, post hoc power = 0.98, effect size: Cohen’s d = 0.71) with the sensorimotor insole (18.1 ± 11.3 % MVCs) than with the control insole (11.2 ± 7.7 % MVCs). No significant effects were established for the other gait phases or for the tibialis anterior.ConclusionsAn increase of muscle activity of the peroneus longus muscle was observed during the loading response and mid-stance phase, when orthopedic insoles with a lateral pressure point were worn. We conclude that the pressure point changes afferent information and leads to an increased peroneus longus activation in the time interval in which the pressure point exerted pressure on the peroneal tendon.

“…(10) This behavior can cause stress and excessive burden on the soft tissues and bony structures, giving origins to cumulative microtrauma and musculoskeletal pain. (11) It is consensus in the literature that excessive subtalar pronation is a major cause of lower limb injuries, especially runners, where this mechanism shall be triggered constantly during the race in order to minimize the harmful effects of the resultant force (normal force) coming from the foot contact with the ground, as well as the excessive internal rotation of the tibia (12). In an attempt to minimize injuries in pronators individuals, clinical physical therapy practice has suggested the use of orthoses able to restrict excess motion of the subtalar joint.…”

Background: The excessive motion of subtalar pronation of the foot, can cause stress and burden in tissues of the region, giving origin to aches and microtrauma. In clinical practice, excessive movement has been limited to the use of techniques of bandages applied to the plantar arch. Objective: Was to analyze the influence of rigid bandage in plantar pressure distribution corridors pronators. Method: This is a randomized clinical trial, blinded, with twenty runners pronators (33±7 y, 71±7 kg, 174±6 cm). Technique was applied bandage (rigid - BR) to support the plantar arch, described as antipronation. Plantar pressure data were collected using the F -scan system in three tests run at 9 km/h being: no bandages, rigid taping. We considered seven areas of pressure for data analysis, performed by means of ANOVA for repeated measures followed by paired t test. Results: BR resulted in significant reductions (p<0.05) in contact pressures and peak pressure rearfoot. Conclusion: Thus, we conclude that BR provided decrease in contact pressures and peak pressure foot, being significant on the hindfoot than in the midfoot.
