Which combination describes typical adaptations to chronic resistance training in muscle, tendon, and bone?

• A. Muscle hypertrophy and neural adaptations; increased tendon stiffness; improved bone mineral density and bone strength.
• B. Decreased tendon stiffness and reduced bone density with no muscle growth.
• C. No changes in muscle size or tendon properties.
• D. Muscle atrophy with increased tendon stiffness.

Answer: (A)

Long-term resistance training triggers coordinated adaptations across muscle, tendon, and bone to handle increased load. Muscles adapt by hypertrophying, adding contractile proteins and enlarging cross-sectional area, while neural systems improve with greater motor unit recruitment, firing efficiency, and coordination. Tendons adapt by remodeling collagen to become stiffer, helping transmit force more effectively and reducing risk of injury. Bones respond to repeated loading through mechanotransduction, increasing bone mineral density and overall strength, especially in weight-bearing sites. This combination—muscle growth with neural gains, stiffer tendons, and stronger bones—best matches the described pattern of adaptations.
