Energy Systems
Definition
The three metabolic pathways that produce ATP for muscle contraction: ATP-PC (phosphagen, 0-10s), Glycolytic (10s-2min), and Oxidative (2min+).
Why It Matters
Understanding energy systems helps you design appropriate rest periods, select training modalities, and match your conditioning work to sport-specific demands.
How to Apply
For strength/power (ATP-PC): short intense efforts with full recovery (3-5min). For hypertrophy/strength-endurance (Glycolytic): moderate efforts 30s-2min with incomplete recovery (1-3min). For endurance (Oxidative): sustained efforts 3min+ with active recovery.
Common Mistakes & Fixes
- ⚠Not allowing sufficient rest for the energy system being trained
- ⚠Mixing energy system demands within the same workout without strategy
- ⚠Overtraining one system while neglecting others
- ⚠Not understanding how fatigue differs across energy systems
