“…This widespread use occurred in spite of a ban at the Little League level, a National Federation of State High School Associations recommendation against use, an NCAA regulation enacted in 1994, and a ban at the Minor League level enacted in 1993 that outlaws the use of ST products for all on-field personnel in practice and competition (Burak, 2001;Connolly, Orleans, & Blum, 1992;Eaves et al, 2009;Gansky et al, 2005;Severson, Klein, Lichtenstein, Kaufman, & Orleans, 2005;Sinusas & Coroso, 2006). The lack of enforcement of existing policies may reflect a lack of support from the coaches, either through negative role modeling (coaches' personal use) or through a reticence to enforce the ban (Chakravorty, Buchanan, & Osfeldt, 1997;Walsh et al, 1994;Walsh, Ellison, Hilton, Chesney, & Ernster, 2000).…”
