Dear List Member, I have recently measured the VO2max and maximum "aerobic" running speed of 35 professional rugby players and found only very moderate correlations between their VO2max and the speed thei can achieve at the last completed stage (protocol used: 2 minute stages with 1km/h increment; grade 1%; starting speed 11km/h). Here are the correlation I got: Last completed stage and VO2max (L/min): r=0.01 Last completed stage and VO2max (mL/kg/min): r=0.35 Last completed stage and VO2max (mL/kg^0.75/min): r=0.52 Last completed stage and body mass (kg): r=-0.57 Since it is common to read that relative VO2max (in mL/kg/min or mL/kg^0,75/min) is highly correlated to the maximum running speed that can be achieved by an athlete during a multistage protocol on treadmill, I am quite puzzled by the low-to-moderate correlation coefficients observed between the various expressions of VO2max and the maximum "aerobic" speed of these professional athletes. If anyone on the list has some comments regarding this phenomenon I would greatly appreciate his/her help. Thank you, Fran�ois Gazzano -------- View all messages at http://sportsci.org/forum.
