Red muscle fibers are fatigue-resistant due to high myoglobin and abundant mitochondria, allowing sustained aerobic activity​. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Red muscle fibers are adapted for slow, sustained activity due to their high myoglobin and mitochondria content.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Disorders of Muscular and Skeletal System
Slow-twitch muscle fibers are rich in mitochondria and myoglobin, making them ideal for endurance activities.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Appendicular Skeleton - Pectoral and Pelvic Girdles
Red muscle fibers have high myoglobin content and numerous mitochondria, making them fatigue-resistant and ideal for endurance activities.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Appendicular Skeleton - Pectoral and Pelvic Girdles
White muscle fibers have fewer mitochondria, contract quickly, and fatigue faster than red muscle fibers.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Appendicular Skeleton - Pectoral and Pelvic Girdles
Red muscle fibers contain a high amount of myoglobin and mitochondria, making them suited for aerobic respiration.

Smooth muscle fibers are non-striated, unlike skeletal and cardiac muscles.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle - Types and Structure - Myofibril Sarcomere Myofilament
Skeletal muscle fibers are voluntary, not involuntary.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Muscle - Types and Structure - Myofibril Sarcomere Myofilament
Slow-twitch fibers contain more myoglobin and mitochondria, making them ideal for endurance activities.
Ref: NCERT Class 11 Biology Chapter 17: Locomotion and Movement Types of Movement - Amoeboid Ciliary Flagellar Muscular
The neuromuscular junction is the site where motor neurons transmit signals to muscle fibers, triggering contraction.
