GPS in Gaelic football: Does volume or intensity better indicate player recovery time
Halson (2014) suggested the importance of monitoring both internal and external training load measures for optimisation of recovery and subsequent performances. Global Positioning System (GPS) has become common place in quantifying external load in team sport athletes, however, alone it is insufficient. Immunoendocrine markers have allowed exploration of individual load tolerance in rugby and soccer, with salivary testosterone (T) and cortisol (C) demonstrating fluctuations in response to competitive matchplay (West et al., 2014) with temporary immunosuppression also reported (Cunniffe et al., 2010). Exploring the relationship between immunoendocrine concentrations and GPS metrics will allow coaches to better understand the recovery timelines of their athletes, subsequently allowing them to better periodise their recovery and training protocols.
