• Heart size (B): Regular exercise (including playing sports) can lead to cardiac remodeling, which may result in an increase in heart size (e.g., in endurance athletes, the heart can enlarge slightly to pump more blood efficiently).
• Bone density (C): Weight - bearing and resistance sports can stimulate bone formation, increasing bone density over time.
• Range of motion (D): Many sports involve stretching and moving joints through various angles, which can improve the range of motion of joints.
