“…In contrast are the findings of Rodriguez-Sanz et al [34], where the results of Ts were provided for the region of interest (ROI), which included the gastrocnemius and Achilles tendon. This mismatch can be explained by the fact that the skin is thinner in that region and the inside structures have more influence on the skin surface due to the lesser interference of subcutaneous fat [35]. At the end of the passive break, Ts was increased, and that change was more considerable following the control treatment compared to baseline values (effect sizes were 0.25 and 0.20 for the experimental and control treatments, respectively; see Figure 2).…”

Maintaining the state achieved after the warm-up in modern soccer represents a significant problem. The main goal of this research was to determine the influence of a regular tracksuit on skin temperature and running speed during the pre-game routine. This study included 36 youth soccer players (15.61 ± 0.68 years, 175.16 ± 4.21 cm) divided into two groups. A two-way ANOVA was used with the level of significance set at <0.05. The main findings of this research indicated that skin temperature is reduced after the WU and is slower to be restored when players wear tracksuits. In addition, the results showed a significant treatment × time-point interaction effect for 10 [p = 0.015, ηp2 = 0.16], 20 [p = 0.001, ηp2 = 0.26], and 30 [p = 0.005, ηp2 = 0.20] meter sprint tests. A significant treatment (experimental vs. control) main effect was observed for 10 m [p = 0.042, ηp2 = 0.35], 20 m [p = 0.020, ηp2 = 0.55], and 30 m [p = 0.005, ηp2 = 0.58] sprint tests. Moreover, a significant sequence-trial interaction effect for 10 m (p = 0.002), 20 m (p < 0.001), and 30 m (p < 0.001) sprints was observed. However, the main effects of the sequence or trial factors alone were insignificant. It is concluded that regular tracksuits may have a beneficial influence on Ts loss and running speed. This research’s most significant practical application is that it lasts for a short period of time and that it requires no extra effort.

“…However, in this research, the photobiomodulation protocol was created based on studies that obtained favorable results using the laser in the treatment of bone lesions. The 904 nm aluminum gallium arsenide pulsed diode laser is the most indicated in the therapeutic process of serious injuries due to its greater ability to penetrate tissues [ 73 , 74 , 75 ]. The literature also cites that this wavelength is capable of promoting an increase in blood flow in live rats, creating an ideal scenario for healing due to good tissue vascularization and efficient collagen deposition [ 76 ].…”

Biomaterials have been investigated as an alternative for the treatment of bone defects, such as chitosan/carbon nanotubes scaffolds, which allow cell proliferation. However, bone regeneration can be accelerated by electrotherapeutic resources that act on bone metabolism, such as low-level laser therapy (LLLT). Thus, this study evaluated the regeneration of bone lesions grafted with chitosan/carbon nanotubes scaffolds and associated with LLLT. For this, a defect (3 mm) was created in the femur of thirty rats, which were divided into 6 groups: Control (G1/Control), LLLT (G2/Laser), Chitosan/Carbon Nanotubes (G3/C+CNTs), Chitosan/Carbon Nanotubes with LLLT (G4/C+CNTs+L), Mineralized Chitosan/Carbon Nanotubes (G5/C+CNTsM) and Mineralized Chitosan/Carbon Nanotubes with LLLT (G6/C+CNTsM+L). After 5 weeks, the biocompatibility of the chitosan/carbon nanotubes scaffolds was observed, with the absence of inflammatory infiltrates and fibrotic tissue. Bone neoformation was denser, thicker and voluminous in G6/C+CNTsM+L. Histomorphometric analyses showed that the relative percentage and standard deviations (mean ± SD) of new bone formation in groups G1 to G6 were 59.93 ± 3.04a (G1/Control), 70.83 ± 1.21b (G2/Laser), 70.09 ± 4.31b (G3/C+CNTs), 81.6 ± 5.74c (G4/C+CNTs+L), 81.4 ± 4.57c (G5/C+CNTsM) and 91.3 ± 4.81d (G6/C+CNTsM+L), respectively, with G6 showing a significant difference in relation to the other groups (a ≠ b ≠ c ≠ d; p < 0.05). Immunohistochemistry also revealed good expression of osteocalcin (OC), osteopontin (OP) and vascular endothelial growth factor (VEGF). It was concluded that chitosan-based carbon nanotube materials combined with LLLT effectively stimulated the bone healing process.

“…A marcação de referência na probe (figura 1) seguia o padrão de ser direcionada ao osso calcâneo e virada para cima para obter a imagem no corte longitudinal (figura 2A) e as imagens no corte transversal, o ponto de referência era voltado para a parte medial do voluntário (figura 2B). As imagens foram nomeadas de acordo com o lado do membro e realizadas medidas do comprimento e espessura, função presente no próprio aparelho (HASLERUD et al, 2017). Legenda: A= Eixo longitudinal (ponto de referência voltado para o osso calcâneo); B= Eixo transversal (ponto de referência sentido linha mediana do participante).…”

O tendão do calcâneo (TC) é o mais forte tendão do corpo humano, com grande capacidade de suportar carga. O TC é vulnerável a lesões por esforço repetitivo por receber muita carga, responsável por 18% de todas as lesões no esporte. O ultrassom (US) diagnóstico é uma técnica barata, dinâmica e rápida para avaliação de tecidos tendíneos, que pode ser associada a testes clínicos para diagnóstico de tendinopatias. Considerando que a simetria do organismo está relacionada com bom estado geral de saúde, objetivou-se neste trabalho avaliar a morfologia e aspectos clínicos do TC de indivíduos com e sem tendinopatia do TC. Participaram do estudo 28 indivíduos: 15 no grupo controle (GC) e 13 no grupo tendinopatia (GT). Os participantes passaram por avaliações específicas do TC: Exame de US, testes à palpação e clínicos. Os sujeitos do GC apresentam média de 0,407cm e 0,389cm da espessura do TC (TC direito e TC esquerdo), e não foram demonstradas anormalidades que indicassem inflamação nas imagens de US e nos testes clínicos. Nos indivíduos do GT, os valores da espessura do TC foram maiores, atingindo até 0,563cm, além de apresentarem alterações nas imagens de US para inflamação. A diferença da espessura do TC entre membros dos indivíduos do GC foi de 10%, enquanto no GT foi de 22%. Por meio dos resultados, sugere-se que diferenças da espessura do TC superiores a 20% indiquem a presença de tendinopatia, comprovadas pelos achados nas imagens de ultrassom e pelos resultados positivos dos testes à palpação e clínicos.
