Effect of high-load and high-volume resistance exercise on the tensiomyographic twitch response of biceps brachii

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.

Comportamiento neuromuscular posterior a la competencia en jugadores profesionales de fútbol de Costa Rica: un seguimiento tensiomiográfico

“…Este tipo de esfuerzos explosivos tienen un impacto sobre las características morfológicas y mecánicas de los músculos del tren inferior, el aumento del tono muscular a causa de la activación aguda neural (Kubo, Kanehisa & Fukunaga, 2001) tal y como se evidencia en el estudio de García-Manso et al, (2012), los cuales reportan el comportamiento del bíceps braquial durante el ejercicio de alto volumen y alta carga, el mismo muestra un aumento gradual del tono muscular durante e inmediatamente posterior al ejercicio, sin embargo, se genera una disminución gradual (aumento del Dm), hasta 15 minutos después de detener la actividad física, los estudios existentes en este campo no reportan lo que sucede 24 horas posterior al ejercicio físico. Sin embargo, como se evidencia en esta investigación, los futbolistas evaluados 24 horas después de la presentación deportiva, no presentan diferencias en los primero tres juegos que fueron sometidos a evaluación, es precisamente en el cuarto juego (último partido) que se denota una diferencia sobre la línea base, generando una disminución del tiempo de contracción.…”

“…It may provide an additional advantage in the applied field to detect between-group differences in cross-sectional comparisons (e.g., talent detection) and within-group changes in longitudinal assessments (e.g., after training and rest periods), as it allows a non-invasive evaluation of the contractile properties (Carrasco et al, 2011;de Paula Simola et al, 2015;Hunter et al, 2012) without producing additional fatigue, and examines muscle in isolation (García-García et al, 2015;Loturco et al, 2015). The TMG mechanical properties have been used to investigate the effects of different types of physical exercise, such as strength (de Paula Simola et al, 2015;García-Manso et al, 2012;Hunter et al, 2012) and endurance (García-Manso et al, 2011), besides estimating the fiber typer composition in skeletal muscle (Simunic et al, 2011). Nonetheless, information concerning differences in TMG mechanical properties of typical endurance and strength/power athletes is spare (Loturco et al, 2015).…”

Tensiomyography parameters and jumping and sprinting performance in Brazilian elite soccer players

“…In the last few years, tensiomyography has emerged as a valid, reliable, and non-invasive method to evaluate the contractile properties of the skeletal muscle (Dahmane, Djordjevic, Simunic, & Valencic, 2005;García-Manso et al, 2012;García-Manso, Rodriguez-Ruiz, et al, 2011;Hunter et al, 2012;Pišot et al, 2008;Tous-Fajardo et al, 2010). During tensiomyography assessment, the magnitude (mm) and duration (ms) of the displacement of a given muscle in response to a single electrical stimulus are captured by a high-precision transducer that is placed over the targeted muscle belly (Valenčič & Knez, 1997 , 2005).…”
