The steady state aerobic powerand the virtual steady statein J/s as functions of work rate P in J/s when running with poles at the angle of inclination of 0.105 radians for 5-min steady state work rates. The lower horizontal line is the lactate threshold = 1654 J/s, and the upper horizontal line the maximal aerobic power . ■: Experimental data, , , , , ,
