“…Using a similar squatting protocol, which produced comparable levels of strength loss (-14% at 48 h) and an exercise intensity of 62% _ VO 2 max , Moysi et al (2005) reported no change in ventilation or HR. In contrast, increases in both ventilation and HR were observed in the present study, despite the fact that subjects exercised a considerably lower intensity, 80%GET, equivalent to *27% _ VO 2 max for these individuals.…”

“…During submaximal cycling, the _ VO 2 response does not appear to be altered by a prior bout of eccentric, muscledamaging exercise (Gleeson et al 1995;Moysi et al 2005;Schneider et al 2007;Twist and Eston 2009). However, the influence of EIMD on other cardiorespiratory and metabolic responses remains in dispute.…”

“…Elevated _ V E and HR responses have been reported during high intensity cycling 48 h after damage-inducing, bench-stepping and have been associated with increases in [La] (Gleeson et al 1995;Schneider et al 2007). During lower intensity exercise (62% _ VO 2 max ) following squatting exercise, _ V E , HR and [La] appear to be unchanged (Moysi et al 2005). Thus, it would appear that mode of damage induction and the intensity and mode of exercise are important factors in determining the response to submaximal exercise with EIMD.…”

Effect of exercise-induced muscle damage on ventilatory and perceived exertion responses to moderate and severe intensity cycle exercise

2009

This study examined the effect of exercise-induced muscle damage (EIMD) on ventilatory and perceived exertion responses to cycle exercise. Ten healthy, physically active men cycled for 6 min at moderate intensity and to exhaustion at severe intensity before and 48 h after eccentric exercise (100 squats with a load corresponding to 70% of body mass). Changes in ventilation and ratings of perceived exertion (RPE) were calculated for each individual and expressed against time (moderate and severe exercise) and as a percentage of time to exhaustion (severe exercise). Ventilation increased during moderate exercise at 48 h V(E); 34.5 +/- 5.0 to 36.3 +/- 3.8 l min(-1), P < 0.05) but increases in RPE were not significant. During severe exercise at 48 h, time to exhaustion (TTE) was reduced and V(E) (87.1 +/- 14.1 to 93.8 +/- 11.7 l min(-1)) and RPE (15.5 +/- 1.3 to 16.1 +/- 1.4) were elevated (P < 0.05). When expressed as a percentage of TTE, the differences in ventilation and RPE values disappeared. Findings indicate that the augmented ventilatory response to cycle exercise following EIMD may be an important cue in informing effort perception during high-intensity exercise but not during moderate-intensity exercise.

“…El entrenamiento de fuerza a través de contracciones concéntricas ha sido el más frecuentemente empleado, debido a que las contracciones excéntricas, se han relacionado con dolor muscular tardío y deterioro funcional de la fibra muscular que se acompaña de una disminución transitoria de los niveles de fuerza máxima, potencia muscular y economía del gesto deportivo (Braun y Dutto, 2003;Cheung, Hume, y Maxwell, 2003;Moysi et al, 2005;Yu et al, 2003). El daño muscular provocado por las contracciones excéntricas, además, se acentúa a medida que aumenta la velocidad de contracción (Chapman et al, 2008), el grado de amplitud, la intensidad y la duración de la misma (Cheung et al, 2003;Moysi et al, 2005;Nosaka, Newton y Sacco, 2002).…”

El entrenamiento de fuerza debe incluirse en todos los programas de ejercicio encaminados a mejorar la salud y la calidad de vida. Los programas de entrenamiento de fuerza han priorizado los regímenes de contracción concéntricos a los excéntricos, sin embargo, actualmente se está realizando un tipo de entrenamiento de fuerza basado en contracciones excéntricas mediante sobrecargas de tipo inercial. Por tanto, el objetivo del presente trabajo de revisión bibliográfica ha sido comprobar los efectos de este tipo de entrenamiento basado en contracciones excéntricas mediante sobrecargas de tipo inercial sobre la función muscular. Para ello se realizó una búsqueda bibliográfica en las bases de datos Web of Science, Pubmed, Medline, Dialnet y Scielo. Los resultados de nuestra revisión sugieren que este tipo de entrenamiento da lugar a una mayor actividad electromiográfica e hipertrofia muscular con respecto a programas de entrenamiento convencionales, al tiempo que podrían ser efectivos en la recuperación de lesiones músculo-tendinosas.PALABRAS CLAVE: excéntrico, volante carga inercial, resistencia inercial, entrenamiento fuerza, fuerza.

Effects of a trail running competition on muscular performance and efficiency in well-trained young and master athletes

et al. 2010

View full text Add to dashboard Cite

To determine the acute effects of a trail running competition and the age-dependent differences between young and master athletes, 23 subjects [10 young (30.5 ± 7 years), 13 master (45.9 ± 5.9 years)] participated in a 55-km trail running competition. The study was conceived as an intervention study compromising pre, post 1, 24, 48 and 72 h measurements. Measurements consisted of blood tests, ergometer cycling and maximal isometric voluntary contractions (MVC). Parameters monitored included MVC, twitch- and M-wave properties, EMG (RMS) of the vastus lateralis, two locomotion efficiency calculations and muscle damage markers in the blood (CK, LDH). Results indicate post-race increases in CK and LDH, decreases in MVC values (-32 vs. -40% in young and master, P < 0.01), decreases in EMG, increases in contraction time and concomitant decreases in peak twitch values, and a decrease in locomotion efficiency (-4.6 vs. -6.3% in young and master, P < 0.05). Masters showed similar fatigue and muscle damage than young but recuperation was slowed in masters. This study shows that trail runs are detrimental to muscle function, and gives indication that training may not halt muscle deterioration through aging, but can help maintain performance level.
