“…Common misconceptions of athletes in a number of studies included protein acting as a primary energy source for muscle contraction (Condon et al, 2007;Jonnalagadda et al, 2001;Rosenbloom et al, 2002;Wiita et al, 1995;Wiita & Stombaugh, 1996;Zawila et al, 2003) and vitamin and mineral supplements delivering energy (Harrison et al, 1991;Jonnalagadda et al, 2001;Rash et al, 2008;Rosenbloom et al, 2002;Zawila et al, 2003). Protein supplements and vitamin and mineral supplements were often reported by athletes as being necessary to achieve peak performance (Harrison et al, 1991;Jonnalagadda et al, 2001;Rash et al, 2008;Rosenbloom et al, 2002;Wiita et al, 1995;Wiita & Stombaugh, 1996;Zawila et al, 2003).…”
