Muscle Hypertrophy

Definition

Muscle hypertrophy refers to the increase in muscle size and is often aimed for in strength training and bodybuilding.

Scientific / Technical Definition

Muscle hypertrophy is the process of enlarging muscle fibers, typically achieved through resistance training that overloads muscle fibers, causing growth in both the number of myofibrils and the volume of muscle cells.

Benefits

• Increased muscle strength and endurance
• Enhanced metabolic rate
• Improved physical performance
• Better body composition
• Increased bone density

Examples

• Weightlifting and resistance training routines
• Bodybuilding programs
• Progressive overload exercises

Additional Information

• Importance: Muscle hypertrophy is important for overall muscle health, improving metabolic rates, and enhancing athletic and functional performance.
