How does duration affect aerobic contribution?

At 10 seconds: roughly 15% aerobic. At 30 seconds: roughly 30% aerobic. At 1 minute: roughly 50% aerobic. At 2 minutes: roughly 65% aerobic. Beyond 10 minutes: above 90% aerobic.

How does intensity affect aerobic contribution?

As intensity approaches VO2 max, aerobic contribution plateaus while anaerobic contribution increases. Above 100% VO2 max, anaerobic systems must supplement aerobic energy delivery.

Why is this important for sport?

Understanding energy system contributions helps coaches design appropriate conditioning. A basketball player needs repeated glycolytic capacity whereas a marathon runner needs maximal aerobic development.
