Is some amount of concussion necessary for strengthening the bone?

Some degree of concussion, or impact, is indeed necessary for bone strengthening. This principle is rooted in the way bones adapt to the physical stresses placed upon them. When bones undergo load or stress through activities such as weight-bearing exercise, they respond by increasing in density and strength—a process known as bone remodeling. This adaptation is facilitated by the activity of cells called osteoblasts, which build new bone tissue.

Engaging in activities that provide appropriate amounts of impact helps stimulate these osteoblasts, promoting healthier bone structure. In the context of equine athletes, controlled exposure to concussion from various training activities can enhance their overall bone health, provided that it is managed carefully to avoid injury.

While it's important to balance workload and recovery to prevent overuse injuries, the foundational concept is that moderate levels of concussive force play a beneficial role in maintaining strong, resilient bones. Thus, some amount of concussion is essential for the effective strengthening of bone.
