Humans possess diverse muscle fiber types (Type 1, Type 2A, Type 2X) designed for specific tasks:
🔴 Type 1 (Slow-twitch): Rich in oxidative metabolism, they primarily use oxygen for energy. Packed with mitochondria and myoglobin, they're reddish & fatigue-resistant. Perfect for endurance tasks like marathons.
🔵 Type 2A: A fast-twitch intermediate between Type 1 & 2X. They contract faster than Type 1 and use both aerobic & anaerobic energy. Suited for activities demanding a balance of strength and stamina, like middle-distance running or high-rep and short rest period weightlifting.
⚪ Type 2X (Fast-twitch): Built for short, powerful actions relying on anaerobic metabolism. Less abundant but essential for high-force tasks like sprinting or olympic lifts.
