You are not entirely correct…
Phosphagen system: uses ATP and creatine to produce energy
Anaerobic alactic system: (technically includes the phosphagen and anaerobic glycolysis) produces energy without the need for oxygen and doesn’t lead to a significant increase in lactic acid. Uses (besides the ATP-CP system) glucose to produce energy.
Anaerobic lactic system: produces energy without the need for oxygen and lead to a significant increase in lactic acid. Uses glucose to produce energy.
Oxydative system: produces energy with the use of oxygen. Uses lipids (free fatty acids), glucose and protein (converted to glucose in the liver) to produce energy.
During endurance work you use primarily free fatty acids and glucose for fuel. Protein can constitute up to 10-15% of the energy production during ultra endurance activities or when the other energy substrates are low.
Here is an approximation of the source of energy production depending on exercise intensity:
65-70% of max heart rate = 40% glucose, 60% fatty acids
70-75% = 50% glucose, 50% fatty acids
75-80% = 65% glucose, 35% fatty acids
80-85% = 80% glucose, 20% fatty acids
85-90% = 90% glucose, 10% fatty acids
90-95% = 95% glucose, 5% fatty acids
100% = 100% glucose, 0% fatty acids
