Objective: Changes in pacing rhythm are translated into functional and metabolic changes that can be significantly reflected in the final results of an athlete. Method: Ten male subjects, with moderate performance level (age: 25.2 ± 2.2 years; VO2max: 56.9 ± 5.7 ml kg−1min−1), performed four 5-min races with different pacing strategies: constant-pace (CP), record-pace (RP), kicker-pace (KP), incremental-pace (IP). Results: The cardio-respiratory response did not show statistically significant. There were statistically significant differences (p ≤ 0.05) in the energetic efficiency among the protocols CP vs. RP, CP vs. KP and RP vs. IP. When results were analyzed by partials (1-min duration phases), significant differences were observed in the energetic efficiency during the 3rd-min among CP vs. KP, RP vs. KP and KP vs. IP. These significant differences were extended to the 4th-min when comparing CP vs. IP, CP vs. KP, KP vs. RP and KP vs. IP. In the last minute of the test, there were significant differences among CP vs. KP. No significant differences were found in any of the variables assessing anaerobic metabolism (accumulated oxygen deficit, oxygen debt, oxygen uptake kinetics and blood lactate) between both protocols. Conclusions: Results suggest that the main functional systems response are significantly affected by the pacing strategy used by middle-level subjects during middle-distance running. Resumen Objetivo: Los cambios en el ritmo de carrera se traducen en cambios funcionales y metabólicos que pueden reflejarse significativamente en los resultados finales de un atleta. Método: Diez sujetos varones, con un nivel medio (edad: 25.2 ± 2.2 años; VO2max: 56.9 ± 5.7 ml kg−1min−1), llevaron a cabo carreras de 5 minutos con diferentes estrategias: ritmo constante (RC), ritmo récord (RR), ritmo kicker (RK) y ritmo incremental (RI). Resultados: La respuesta cardiorespiratoria no mostró diferencia estadísticamente significativa. Hubo diferencias estadísticamente significativas (p ≤ 0.05) en la eficiencia energética entre los protocolos CP vs. RP, CP vs. KP and RP vs. IP. Cuando los resultados se analizaron por parciales (fases de un minuto de duración), se observaron diferencias significativas en le eficiencia energética durante el tercer minuto entre RC vs. RK, RR vs. RK y RK vs. RI. Estas diferencias significativas se extendieron al cuarto minuto cuando se compararon RC vs. RI, RC vs. RK, RK vs. RR y RK vs. RI. En el último minuto del test, hubo diferencias significativas entre RC vs. RK. No se encontraron diferencias significativas en ninguna de las variables que valoran el metabolismo anaeróbico (déficit de oxígeno, deuda de oxígeno, cinética del consumo de oxígeno y lactato en sangre) entre ambos protocolos. Conclusiones: Los resultados sugieren que la respuesta de los principales sistemas funcionales se ve afectada significativamente por la estrategia de carrera empleada por un grupo de sujetos de nivel intermedio durante una carrera de media distancia. Resumo Objetivo: Alterações no ritmo de corrida se traduzem em mudanças funcionais e metabólicas que podem ser refletidas de forma significativa nos resultados finais de um atleta. Método: Dez indivíduos do sexo masculino, com nível de desempenho moderado (idade: 25.2 ± 2.2 anos; VO2máx: 56.92 ± 5.7 ml kg-1 min-1), realizaram quatro corridas de 5 minutos com diferentes estratégias de corrida: velocidade constante, velocidade recorde, velocidade kicher e velocidade incrementada. Resultados: A resposta cardiorrespiratória não demostrou estatisticamente significativa. Houve diferenças estatisticamente significativas (p ≤ 0.05) na eficiência energética entre os protocolos CP vs. RP, CP vs. KP and RP vs. IP, quando os resultados foram analisados por parciais (1min de duração). Foram observadas diferenças significativas na eficiência energética durante o 3°-min entre CP vs. KP, RP vs. KP e KP vs. IP. Estas diferenças significativas foram estendidas para o 4°-min na comparação CP vs. IP, CP vs. KP, CP vs. KP, KP vs. RP e KP vs. IP. No último minuto do teste, houve diferenças significativas entre CP vs. KP. Não foram encontradas diferenças significativas em nenhuma das variáveis que avaliam o metabolismo anaeróbico (déficit de oxigênio acumulado, débito de oxigênio, cinética do consumo de oxigênio e lactato no sangue) entre ambos os protocolos. Conclusões: Os resultados sugerem que as principais respostas dos sistemas funcionais são afetadas significativamente pela estratégia de corrida usado por indivíduos de nível médio durante a meia-corrida de longa distância.

Objetivo: El presente estudio tuvo como objetivo el verificar si el control postural, en condiciones estáticas, es un factor discriminante entre niñas practicantes de gimnasia rítmica (GR) de alto nivel y sus homólogas normalmente activas. Método: Dieciséis atletas practicantes de GR que competían a nivel nacional español (GR: 9,7 ± 1,4 años; 32,3 ± 3,6 kg, 143,1 ± 7,4 cm) y 16 niñas no deportistas (GC) (GC: 9,8 ± 0,9 años; 36,2 ± 5,4 kg; 139,2 ± 6,9 cm) participaron en la investigación. Todos los sujetos realizaron 2 pruebas: una con ojos abiertos (OA) y la otra con ojos cerrados (OC), que consistían en mantenerse inmóvil durante 30 segundos sobre una plataforma de fuerza. Basándose en el desplazamiento del centro de presiones (CP) las variables calculadas fueron: Área de la Elipse del 95% (A95), Velocidad Media Total (VM T), Velocidad Antero-Posterior (VM A/P) y la Velocidad Medio-Lateral (VM M/L). Se realizó un análisis de frecuencia (transforma rápida de Fourier) del desplazamiento del CP. Resultados: Se observaron diferencias significativas cuando se comparan los grupos para VM M/L y VM T, pero no para A95, en OA y OC. Curiosamente, el grupo de GR mostró mayores valores de VM M/L que el grupo de GC en ambas condiciones. La ausencia de la visión, afectó menos al grupo de GR. La transformada de Fourier reveló que el grupo de GR obtuvo valores más elevados de densidad espectral en el plano M/L. Conclusión: Los resultados sugieren que el control postural, en condiciones estáticas, es un factor discriminante entre niñas practicantes de GR y sus homólogas no deportistas. Sin embargo, metodologías tradicionales para el análisis del CP no son lo suficiente sensibles para el total entendimiento de la dinámica del CP. Objective: The aim of this study was to evaluate if the postural control in static conditions, is a discriminating factor between gymnastics rhythmic girls and their normally active counterparts. Methods: Sixteen rhythmic gymnastics girls of national level (RG) (RG: 9.7 ± 1.4 years; 32.3 ± 3.6 kg, 143.1 ± 7.4 cm) and sixteen school girls (SG) (SG: 9.8 ± 0.9 years; 36.2 ± 5.4 kg; 139.2 ± 6.9 cm) participated in the investigation. All subjects performed two postural control tests: Bipedal Eyes Open (EO) and Eyes Closed (EC), while standing on a platform force, as immobile as possible for 30 seconds. Based on the center of pressure displacement, variables analyzed were: Ellipse Area of 95 (A95), Mean Velocity (MV T), Mean Velocity in the anterior-posterior plane (MV A/P) and Mean Velocity in the medium-lateral plane (MV M/L). A frequency domain analysis of the center of pressure (Fast Fourier Transform) was performed. Results: Significant differences were observed when comparing groups for MV M/L and MV T, but not for A95, in EO and EC. Interestingly, RG showed greater values of MV M/L than SG in all conditions. In absence of vision, both groups were affected, but there was a trend to be weaker this effect in RG. The Fourier Transform showed that gymnastics had higher values of energy of the spectrum in the M/L plane. Conclusions: The results suggest that postural control in static conditions is a discriminating factor between gymnastics rhythmic girls and their normally active counterparts. However, traditional methods for the analysis of the CP seem to be not reliable to understand the dynamics of the CP. Objetivo: O presente estudo teve como objetivo verificar se o controle postural, em condições estáticas, é um fator discriminante entre meninas praticantes de ginastica rítmica (GR) de alto nível e seus pares normalmente ativas. Métodos: Dezesseis atletas praticantes de GR que competiam a nível nacional espanhol (GR: 9,7 ± 1,4 anos; 32,3 ± 3,6 kg, 143,1 ± 7,4 cm) e 16 meninas não atletas (GC) (GC: 9,8 ± 0,9 anos; 36,2 ± 5,4 kg; 139,2 ± 6,9 cm) participaram deste estudo. Todas as voluntárias realizaram 2 provas, uma com olhos abertos (OA) e a outra com olhos fechados (OF), que consistiam em manter-se imóveis durante 30 segundos sobre uma plataforma de força. Baseado no deslocamento do centro de pressão, as variáveis calculadas foram: Área da Elipse de 95% (A95), Velocidade Média Total (VM T), Velocidade Antero-Posterior (VM A/P), Velocidade Médio-Lateral (VM M/L) e análise de frequência (transformada rápida de Fourier). Resultados: Foi observada diferença significativa quando compararam os grupos para VM M/L e VM T, mas não houve diferença para A95 com OA e OF. Curiosamente, GR demonstrou maiores valores de VM M/L que GC em ambas as condições. A ausência da visão afetou menos o grupo GR. A transformada de Fourier revelou que o grupo GR obteve maiores valores de densidade espectral no plano M/L. Conclusões: Os resultados sugerem que o controle postural, em condições estáticas, é um fator discriminante entre meninas praticantes de GR e o grupo controle não atleta. Contudo, metodologias tradicionais para a análise de CP não são sensíveis para total entendimento da dinâmica do CP.

- Abstract
The aim of this study was to evaluate the normalized response speed (Vrn) of the knee musculature (flexor and extensor) in high competitive level volleyball players using tensiomyography (TMG) and to analyze the muscular response of the vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), and biceps femoris (BF) in accordance with the specific position they play in their teams. One hundred and sixty-six players (83 women and 83 men) were evaluated. They belonged to eight teams in the Spanish women's superleague and eight in the Spanish men's superleague. The use of Vrn allows avoiding possible sample imbalances due to anatomical and functional differences and demands. We found differences between Vrn in each of the muscles responsible for extension (VM, RF, and VL) and flexion (BF) regardless of the sex. Normalized response speed differences seem to be larger in setters, liberos and outside players compared to middle blockers and larger in males when compared to females. These results of Vrn might respond to the differences in the physical and technical demands of each specific position, showing an improved balance response of the knee extensor and flexor musculature in male professional volleyball players.

The true effectiveness in volleyball is related to the ability to perform quick displacements and jumping-related techniques. The monitoring of the muscular response has been related to functional capacity of the knee flexor and extensor muscles in other population. It is of utmost importance to the study the muscular structures that enhance volleyball performance. The aim of this study was to analyze the responses of the normalized response speed and jumping-related techniques in a group of professional female volleyball players. 2.075 JCR (2014) Q2, 23/81 Sport sciences UEM

The Use of Vignola’s Treatise as a Model for the Architecture of Modern Age in Sicily. The paper aims to highlight the influence of the Regola Delli Cinque Ordini by Jacopo Barozzi da Vignola (1507-1573) on the architecture of modern age in Sicily. A proof of its actual im- pact on built items can be promptly observed analyzing the ar- chitecture of the time which clearly shows the treatise was used as a catalogue of models in the whole territory of the island, in civil as well as in religious buildings. Not always, however, the engravings are slavishly copied; sometimes the tables are subject to a revision on behalf of architects, craftsmen and clients. Among the engravings whose influence is ascertained through built items we can find both the ones drawn from the works by Vignola and those related to the Aggiunta containing the seven portals by Michelangelo. This paper particularly focuses on two key topics: on one hand, the success of the famous engraving representing the portal of Palazzo Farnese in Caprarola; on the other hand, the case, in some ways emblematic, of the large application of Vignola’s treatise in the reconstruction of the city of Noto after the disastrous earthquake of 1693.

- Abstract
Background: Futsal is a team sport involving intermittent technical actions of high intensity, and high physical (strength) and muscular demands. In this regard, the tensiomyography (TMG) is a useful and non-invasive tool for the monitoring and assessment of the muscle's contractile capacity. This study aimed to analyze the changes in the contractile properties produced during the season, as well as to determine the potential cumulative effect of a resistance training (RT) program in futsal players., Methods: Fourteen elite futsal players (2 goalkeepers, 4 defenders, 4 wingers and 3 pivots) were assessed by TMG at 11th, 18th, and 28th week of the season. The maximal radial displacement of the muscle belly (Dm); contraction time (Tc); delay time (Td) and radial displacement velocity (90%) Dm (VrD90) were assessed. After the second measurement, a RT program was included in the regular training sessions and focused on the lower body musculature. It was performed during 9 weeks (1-weekly). Finally, a third measurement was performed between 28th-29th weeks. Repeated measures analysis of variance was used to detect in-season changes. Two factors were included: Time (changes detected after resistance training program) was used as the within-subject factor and the specific position was used as the between-subject factor., Results: An increment in Tc for several muscles: biceps femoris (BF; P=0.02), semitendinosus (ST; P=0.04), adductor longus (AL; P=0.008) and gastrocnemius medialis (GM; P=0.009) was observed throughout the season. Similarly, significant increments in Dm for GM (P=0.02) and AL (P=0.05), as well as increments in Td for BF (P=0.002) were found. Moreover, no significant changes in VrD90 between time points 2-3 (analysis of RT effect) were observed. Additionally, the player´s positions reported no significant changes for any of the variables analyzed., Conclusions: An increase respect to baseline levels was observed for Tc, Td and Dm during the season. However, the adaptations to contractile properties were muscle specific. In addition, an in-season 9-week RT program (1-weekly), had no significant effects (time points 2-3) on the contractile properties of futsal players. In addition, there were no differences when comparing different positions.

Martín-Rodríguez, S, Loturco, I, Hunter, AM, Rodríguez-Ruiz, D, and Munguia-Izquierdo, D. Reliability and measurement error of tensiomyography to assess mechanical muscle function: A systematic review. J Strength Cond Res 31(12): 3524-3536, 2017-Interest in studying mechanical skeletal muscle function through tensiomyography (TMG) has increased in recent years. This systematic review aimed to (a) report the reliability and measurement error of all TMG parameters (i.e., maximum radial displacement of the muscle belly [Dm], contraction time [Tc], delay time [Td], half-relaxation time [½ Tr], and sustained contraction time [Ts]) and (b) to provide critical reflection on how to perform accurate and appropriate measurements for informing clinicians, exercise professionals, and researchers. A comprehensive literature search was performed of the Pubmed, Scopus, Science Direct, and Cochrane databases up to July 2017. Eight studies were included in this systematic review. Meta-analysis could not be performed because of the low quality of the evidence of some studies evaluated. Overall, the review of the 9 studies involving 158 participants revealed high relative reliability (intraclass correlation coefficient [ICC]) for Dm (0.91-0.99); moderate-to-high ICC for Ts (0.80-0.96), Tc (0.70-0.98), and ½ Tr (0.77-0.93); and low-to-high ICC for Td (0.60-0.98), independently of the evaluated muscles. In addition, absolute reliability (coefficient of variation [CV]) was low for all TMG parameters except for ½ Tr (CV = >20%), whereas measurement error indexes were high for this parameter. In conclusion, this study indicates that 3 of the TMG parameters (Dm, Td, and Tc) are highly reliable, whereas ½ Tr demonstrate insufficient reliability, and thus should not be used in future studies.

- Abstract
Under hypoxia, alterations in muscle contractile properties and faster fatigue development have been reported. This study investigated the efficacy of tensiomyography (TMG) in assessing muscle contractile function at acute moderate altitude. Biceps femoris (BF) and vastus lateralis (VL) muscles of 18 athletes (age 20.1 ± 6.1 years; body mass 65.4 ± 13.9 kg; height 174.6 ± 9.5 cm) were assessed at sea level and moderate altitude using electrically evoked contractions on two consecutive days. Maximum radial displacement (Dm), time of contraction (Tc), reaction time (Td), sustained contraction time (Ts), and relaxation time (Tr) were recorded at 40, 60, 80, and 100 mA. At altitude, VL showed lower Dm values at 40 mA (p = 0.008; ES = -0.237). Biceps femoris showed Dm decrements in all electrical stimulations (p < 0.001, ES > 0.61). In VL, Tc was longer at altitude at 40 (p = 0.031, ES = 0.56), and 100 mA (p = 0.03, ES = 0.51). Regarding Td, VL showed significant increases in all electrical intensities under hypoxia (p ≤ 0.03, ES ≥ 0.33). TMG appears effective at detecting slight changes in the muscle contractile properties at moderate altitude. Further research involving TMG along with other muscle function assessment methods is needed to provide additional insight into peripheral neuromuscular alterations at moderate altitude.

- Abstract
The purpose of the present study was to assess the ability of TMG in detecting mechanical fatigue induced by two different resistance exercises on biceps brachii: high-volume (HV), and high-load (HL). Sixteen healthy subjects (age 25.1±2.6years; body mass 79.9±8.9kg; height 179±7.4cm) performed arm-curl in two different protocols (HV: 8×15×10kg, HL: 5×3×30kg). Tensiomyography was used to assess muscle response to both exercise protocols. The contractile capacity of biceps brachii significantly varied by means of the effects of potentiation and fatigue mechanisms that take place at different exercise phases. The most significant changes correspond to values of maximum radial displacement of muscle belly (D(m)), sustained contraction time (T(s)), relaxation time (T(r)), and contraction velocity (V(c)). The behavior of these parameters is, in general, similar in both exercise protocols, but they show subtle differences among them. During the first set, in both protocols, values for V(c) increase, along with a decrease in T(r), T(s), and D(m) values. Fatigue onset was evident from changes in such parameters, with HL being the first in showing these mechanisms. Tensiomyography has been shown to be highly sensitive in detecting fatigue-induced changes., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

- Abstract
Objective: This study was designed to analyze changes in muscle response after cold-water immersion., Design: The vastus lateralis of the dominant leg was analyzed in 12 professional soccer players from the Spanish 2nd Division B using tensiomyography, before and after four cold-water immersions at 4°C lasting 4 mins each. Core temperature, skin temperature, and heart rate were monitored., Results: A significant interaction (P ≤ 0.05) was found in muscle deformation between control conditions (5.12 ± 2.27 mm) and (1) immersion 3 (3.64 ± 2.27 mm) and (2) immersion 4 (3.38 ± 1.34 mm). A steady decrease was also observed in response velocity (immersion 1, -7.3%; immersion 2, -25.9%; immersion 3, -30.0%; immersion 4, -36.6%) and contraction velocity (immersion 1, -11.5%; immersion 2, -22.1%; immersion 3, -35.0%; immersion 4, -41.9%), with statistically significant differences (P ≤ 0.05) in relation to the reference values commencing with the third immersion. No significant differences were found between control conditions in subsequent exposures to cold water for the values of response time and contraction time. Sustained time and reaction time showed an increase during repeated exposures and with longer exposure time, although the increase was not statistically significant., Conclusions: This study shows that repeated cold-water immersions (4 × 4 mins at 4°C) cause considerable alterations to muscle behavior. These alterations significantly affect the state of muscles and their response capacity, particularly in relation to muscle stiffness and muscle contraction velocity.

- Abstract
In this study, we used tensiomyography (TMG) to assess muscle status immediately after an ultra-endurance triathlon. Maximal radial displacement or deformation of the muscle belly, contraction time, delay time, sustain time, and relaxation time were measured for both legs, and dependent t-tests were used to compare means between the beginning and end of the race. The 19 men assessed (age 37.9 ± 7.1 years; height 177.5 ± 4.6 cm; weight: 73.6 ± 6.5 kg) participated in the 2009 edition of the Lanzarote Ironman. Deterioration in the neural response was observed for contraction time (P = 0.008) and relaxation time (P = 0.011), with a moderate decrease in the response time (sustain time) and a loss in muscle stiffness (deformation of the muscle belly). The effect of muscle fatigue on the rectus femoris and biceps femoris was different. Barely any changes in contraction time, relaxation time, sustain time, and deformation of the muscle belly were observed, while only the contraction response time decreased to a significant extent (reduction in delay time; P = 0.003). The considerable loss in contractile capacity induced by a long-distance race was reflected in changes in the neuromuscular response and fluctuations in the contractile capacity of the muscle. These modifications, derived from a prolonged, exhausting effort, can be assessed in a simple, non-aggressive, non-invasive way using tensiomyography.

- Abstract
The aim of this study was to determine whether the in-game role of players (setter, outside, middle, or opposite player) in elite women's volleyball is significantly related to the characteristics of their service. The sample consisted of 1,300 service deliveries (total serves for all matches) made by players in the 8 teams participating in 2 Final 4 stages of the Indesit European Champions League. The variables recorded were in-game role of the server, service type, speed of delivery, service area, target zone, and effectiveness of delivery. Results showed a significant relation between the server's in-game role and service type (p
