“…doi:10. 1016/j.jneumeth.2005.06.025 the onset of fatigue for the superficial muscles of the quadriceps femoris (deVries et al, 1982(deVries et al, , 1987Evetovich et al, 1996;Housh et al, 1996), examine the physiological mechanisms underlying neuromuscular fatigue (Housh et al, , 1991, quantify the effects of endurance training in the elderly (deVries et al, 1989), describe muscle activation patterns during submaximal Housh et al, 2000) and supramaximal (Hunter et al, 2003;Vandewalle et al, 1991) workbouts, and examine the relationship between the "iEMG threshold" and the "aerobic-anaerobic transition" in elite cyclists (Lucia et al, 1999) and cardiac transplant patients (Lucia et al, 1997). In addition, recent studies have examined the relationship between muscle activation patterns and the slow component of oxygen uptake kinetics during constant power output exercise for the moderate, heavy, and severe exercise domains (Jones and Poole, 2004;Lucia et al, 2000;Scheuermann et al, 2001;Shinohara and Moritani, 1992).…”
