Your power endurance profile indicates how likely you are to respond to power or endurance stimuli, not how good you currently are at those activities.
Power activities are classed as those of very high intensity, lifting heavy weights for low reps, sprinting, jumping etc.
Endurance activities are those that have a higher volume at lower intensities, for example moderate weight for higher repetitions, or sporting activities lasting over 2 minutes of sustained effort.
The best way for you to train will of course depend on your sport, your training history, and your goals. However your power endurance ratio can inform how much benefit you will see from certain training styles, and therefore how much time you should spend training in a power or endurance manner in pursuit of those goals.
For example, for someone with a 60:40 Power-Endurance split, we would recommend 60% of your training time directed towards power activities, and 40% directed towards endurance activities.
