significant reduction in ability to complete 1-km and 4-km sprints undertaken at ∼90% peak power output interspersed within the protocol ( Havemann et al., 2006 ). This reduction in power output matches the ∼30% reduction in PDH and estimated glycogenolysis during a 1-min sprint at 150% of peak power output
