“…The absence of a change in PA post-eccentric training might be due to measurement errors in US image analysis (Baroni et al, 2013b). While eccentric training and conventional resistance training seem to increase plantar flexor PA by around 1.2–4.0° (Morse et al, 2007; Duclay et al, 2009; Vieillevoye et al, 2010; Sanz-Lopez et al, 2016), ultrasonographic analyses have shown a TE of 0.15–3.7 (de Boer et al, 2008; Padhiar et al, 2008; Martins et al, 2012; McMahon et al, 2016). Reported PA adaptive responses to strength training are close to the measurement error in US analysis, which could explain results from studies that found an increase in muscle hypertrophy without concomitant changes in PA (Reeves et al, 2009; Raj et al, 2012; Baroni et al, 2013b; Fouré et al, 2013).…”

Triceps Surae Muscle Architecture Adaptations to Eccentric Training

BackgroundEccentric exercises have been used in physical training, injury prevention, and rehabilitation programs. The systematic use of eccentric training promotes specific morphological adaptations on skeletal muscles. However, synergistic muscles, such as the triceps surae components, might display different structural adaptations due to differences in architecture, function, and load sharing. Therefore, the purpose of this study was to determine the effects of an eccentric training program on the triceps surae (GM, gastrocnemius medialis; GL, gastrocnemius lateralis; and SO, soleus) muscle architecture.MethodsTwenty healthy male subjects (26 ± 4 years) underwent a 4-week control period followed by a 12-week eccentric training program. Muscle architecture [fascicle length (FL), pennation angle (PA), and muscle thickness (MT)] of GM, GL, and SO was evaluated every 4 weeks by ultrasonography.ResultsFascicle lengths (GM: 13.2%; GL: 8.8%; SO: 21%) and ML increased (GM: 14.9%; GL: 15.3%; SO: 19.1%) from pre- to post-training, whereas PAs remained similar. GM and SO FL and MT increased up to the 8th training week, whereas GL, FL increased up to the 4th week. SO displayed the highest, and GL the smallest gains in FL post-training.ConclusionAll three synergistic plantar flexor muscles increased FL and MT with eccentric training. MT increased similarly among the synergistic muscles, while the muscle with the shortest FL at baseline (SO) showed the greatest increase in FL.

La flexibilidad muscular es un importante componente de aptitud física y está relacionada con el desempeño de actividades diarias y deportivas. Es determinada por factores intrínsecos y extrínsecos. En el caso de los intrínsecos, se destaca la concentración de titina en los músculos esqueléticos. El objetivo de este estudio fue comparar las concentraciones y la movilidad relativa de las isoformas T1 y T2 de titina después de 16 semanas de entrenamiento con diferentes ejercicios de flexibilidad. Para ello, 51 individuos entrenados, del sexo masculino con edades entre los 19 y 26 años, y con por lo menos 6 meses de entrenamiento físico, fueron divididos en tres grupos: elongación, flexibilización activa y flexibilización pasiva. La elongación no implicó ninguna modificación que pueda desvirtuar los porcentuales y la movilidad de las isoformas de titina. Los grupos que realizaron flexibilización presentaron disminución porcentual de la isoforma T1 y aumento porcentual de la isoforma T2, además del aumento de la movilidad relativa de estas dos isoformas de titina. La flexibilización pasiva implicó en mayores alteraciones en los porcentuales de las isoformas T1 (Δ% = -11.30 % para p < 0.05) y T2 (Δ% = 21.45 % para p < 0.05). La flexibilización activa promovió mayor aumento de movilidad relativa de las isoformas T1 (Δ% = 26.53 % para p < 0.05) y T2 (Δ% = 10.96 % para p < 0.05) de titina.

Introduction. Diabetic neuropathy (DN) is one of the most frequent chronic complications of type 2 diabetes mellitus (DM2). One technique capable of influencing the central and peripheral nervous system is foot reflexology (FR). Therefore, the objective of this study was to analyze the immediate effect of FR in DN type 2 patients. Method. This was a randomized controlled clinical trial, with 12 participants selected from a list of diabetic patients from the Basic Health Units of the city of Alfenas-MG. The sample consisted of two groups: Control Group (n=5) and Intervention Group (n=7). The instruments used were: surface electromyography for analysis of the lateral and medial gastrocnemius muscles, baropodometry to evaluate the balance from the variables of mean pressure and mass division, and the cardiofrequency meter to analyze the relationship between the sympathetic and parasympathetic nervous system and cardiovascular stress. Statistical analysis was used the Shapiro-Wilk test and later the independent t test and Mann Whitney for intergroup comparison. Results. There was only a difference in the EMG of the right lateral gastrocnemius muscle (p=0.04). Conclusion. It was concluded that FR was able to generate response in muscle electrical activity, besides influencing the balance of DN2 patients.
