a. cycling
b. swimming
c. running
d. walking
please select the best answer from the choices provided.
a
b
c
d

Explanation:

To determine which aerobic activity has the highest joint impact, we analyze each option:

• Cycling (A): It is a low - impact activity as the body is supported by the bike, reducing stress on joints.
• Swimming (B): The buoyancy of water reduces the weight - bearing stress on joints, making it a low - impact exercise.
• Running (C): When running, the body repeatedly hits the ground with a force greater than body weight (usually 2 - 3 times body weight), which places significant stress on the joints (like knees, ankles, and hips).
• Walking (D): Walking has a lower impact than running as the force exerted on the joints is about 1 - 1.5 times body weight.

Among these activities, running exerts the most force on the joints.

Answer:

C. running
