Heart Rate Training… why know your LT and VO2max

Vo2 Max and Anaerobic Threshold Analysis

VO2 max and anaerobic threshold are predictors of your endurance. Both are very important if you are training for an endurance event or want to know your training parameters.

  • VO2 max (maximal aerobic power) — the maximum amount of oxygen that can be used by muscles in a given period of time. VO2 max is your maximal rate of oxygen consumption and a measure of your capacity to generate the energy required for endurance activities. To assess VO2 max, the athlete performs progressively intensive exercise, during which ventilation and oxygen concentration of inhaled and exhaled air are measured. VO2 max testing is performed on a bike or treadmill and a metabolic analysis is done. The results provide max levels of heart rate, VO2, VCO2 and anaerobic threshold.
  • Anaerobic threshold — the point at which lactate removal fails to keep up with the rate of lactate production as exercise intensity increases. At the anaerobic threshold, lactate starts to accumulate in the blood because it is produced faster than it can be removed (metabolized). The anaerobic threshold is a useful measure for determining exercise intensity for training and racing in endurance sports. The threshold can be greatly increased with training.

I highly recommend you utilize the service Froedtert Sports Medicine offers in getting your LT/VO2max tested, this will not only give you the hard data to train the most efficiently and effectively but it will ensure you are not wasting your time training outside of your zones).
