Humans Energy Systems and Muscle Fibers

The human body's energy systems and muscle fibers are intricately designed to support various physical activities. ATP, or adenosine triphosphate, acts as the primary energy currency, fueling cellular functions by breaking down food.

Energy Systems

Glycolysis

Also not endurance

Glucose

15 sec - 2 minutes

Lactic Acid Buildup

2 ATP molecules

Anaerobic lactic

10-15 sec

100m sprint

Creatine Phosphate

Powerful

Quick movement

No oxygen

1 ATP Molecule

Moderate fatigue

Slow Twitch
Type 1

Better for Endurance

Maintain low energy levels for longer periods of time

Make energy slower then others

Red and darker in color

Diameter can increase with training

High in myoglobin
