Champion Physiology: What Makes you Fast? (PezCycling News)- Weight Loss News

Overall, at the broadest level, the three primary determinants for performance appear to be aerobic capacity (VO2max), lactate threshold, and also the newer concept of “efficiency. VO2max As most of us know, VO2max stands for our maximal oxygen consumption, and had long been considered the be-all and end-all of endurance performance. While it is obvious that, at the elite levels, a certain VO2max is the basic entry requirement for world-beating performances, it also quickly became evident that endurance performance beyond 10 min or so is conducted at intensities less than VO2max. For example, a marathon pace is typically 75-85% VO2max, a 10 km run pace is 90-100% VO2max, and a 5 km run close to 100% VO2max. Rider B has a VO2max of 50 mL/kg/min, but his LT is at 90% or 45 mL/kg/min. read more
