More interestingly, Farup et al. (2014) found that the strength of the relationship between rate of force development and type IIX muscle fiber relative area reduced steadily as the time period moved further away from the onset of the contraction (r = 0.61, 0.56, 0.46, 0.26 for 30ms, 50ms, 100ms and 200ms).

Nevertheless, there does appear to be a difference in type IIA and type IIX muscle fiber proportion between strength and power athletes and their respective controls, with most studies reporting a greater proportion of type IIA, and a smaller proportion of type IIX fibers in the athletes (Klitgaard et al. 1990; Jürimäe et al. 1996; Fry et al. 2003a; Fry et al. 2003b; Shoepe et al. 2003; Kesidis et al. 2008) but again this is not seen entirely consistently (D'Antona et al. 2006).
