Unformatted text preview: -however, not 100% efficient-no proven systematic relevance/proof that traingin affects efficiency-more genetics-ex.:-Work=900 kgm/min-VO2=3.0L O2/min-Resting VO2=.3L0@/min-E(gross)=work done / energy used= 900/3.0L x 2153= 13.9% efficiency-E(net)=subtract out resting VO2 from denominator(energy used)-economy=doing less work then someone else-use more energy running hills than flat even if total elevation=0- save 40% ATP and rest dissipated for heat when consum carbo, protein, fat...
