The demands of Academy football match-play include a requirement to cover distances of ~7-11 km (Goto et al., 2015), perform explosive bouts of skill-based work (Stolen et al., 2005) and run at high intensities (>3.0 m s−2) for up to 375 ± 120 m per half (Russell et al., 2015), whilst eliciting mean whole-match intensities of 70-80% V̇O2max (Bangsbo, 2010). The ability to sustain such demands is integral to the performance outcome (Krustrup et al., 2006), as match-related fatigue has been reported both transiently throughout a game (Krustrup et al. 2006) and from 45 min onwards (Harper et al., 2016; Russell et al., 2015; Russell et al., 2011; Mohr et al., 2005). Although fatigue is likely multifaceted in origin, previous studies have highlighted the role of both habitual and pre-exercise nutritional status on the ability to maintain performance and to enable effective recovery (Anderson et al., 2016).
Habitual energy intake, and in particular, consumption on match-days and heavy training days have been highlighted as an area of concern with respect to estimated energy balance in Academy football players, with daily deficits of 500-550 Kcal·d-1 reported (Briggs et al., 2015). Such data agrees with that of previous authors who reported mean daily energy deficits of ~300–800 Kcal·d-1 in this population (Russell and Pennock, 2011; Caccialanza et al., 2007; Ruiz et al., 2005; Leblanc et al., 2002; Boisseau at al., 2002). In the case of the Academy football player, such practices, albeit unconfirmed, may have long-term implications for maintenance of training demands, optimised performance, adequate recovery, as well as detrimental effects on growth and development (Briggs et al. 2015). Therefore, effective strategies are warranted to alleviate sub-optimal energy intakes that are appropriate to meet the practical demands of both a periodised training schedule and multiple match-play fixtures.
