adaptations across all three energy systems, resulting in faster rates of phosphocreatine breakdown and greater glycolytic and mitochondrial enzyme activity ( Ross & Leveritt, 2001 ). Intense sprint exercise results in rapid increases in energy turnover from both aerobic and anaerobic metabolism. Having an

having world-class anaerobic capacities with polished tactical race instincts ( Hanley & Hettinga, 2018 ; Sandford et al., 2018 ). These performance requirements result in highly complex training approaches, with significant differences within and between athletes throughout macro- (yearly/monthly) and

task improvement of ∼6.5% (±5.5%; Astorino & Roberson, 2010 ). Specific protocols involving anaerobic activities include the study of a 1-km cycling TT, where caffeine ingestion (5 mg/kg BM consumed 60 min preexercise) was associated with a 3.1% improvement in task completion time, and a 3.1% and 8

separated by a few hours for recovery. The volumes of aerobic and anaerobic training will fluctuate throughout the season, but technique and explosive speed development is a persistent focus ( Schiffer, 2011 , 2012 ). The lower NM and energetic demands of the anaerobic-dominant training regimen suggest

A respiratory exchange ratio >1 indicated that anaerobic metabolism was likely contributing to muscle work but was not being factored into the energetic cost analysis based on
