What is a long-term muscular adaptation to exercise?

• A. Fatigue
• B. Hypertrophy
• C. Increased joint stability
• D. Sweating

Answer: (B)

Hypertrophy is the long-term muscular adaptation produced by repeated resistance training. When you train regularly, muscle fibers grow in size as the body builds more contractile proteins and other components, leading to bigger muscles and greater strength. This change develops over weeks to months and is a direct change in muscle tissue. Fatigue is a short-term effect that limits performance during a session, not a lasting change. Sweating is a thermoregulatory response to exercise, not a change in muscle. Increased joint stability can occur with training but relates more to the joint’s support and neuromuscular control than a change in muscle size, so it isn’t the primary muscular adaptation described here. Therefore, the best answer is hypertrophy.
