Which of the following statements is true about children in relation to physical activities?

The correct choice highlights the increased susceptibility of children to Osgood Schlatter's disease, a condition related to stress on the knee caused by physical activity. This disease commonly occurs during growth spurts when the bones, muscles, and tendons are developing. Children, particularly active ones, experience repetitive stress on the knee joint due to sports or vigorous play, making them more prone to this condition.

This susceptibility is primarily due to their still-developing bodies, which may not yet be equipped to handle high levels of physical stress, resulting in inflammation and pain at the growth plate located just below the knee. Recognizing this allows personal trainers and caregivers to emphasize appropriate training, rest, and injury prevention strategies in their programs for young athletes.

In contrast, the other statements do not accurately reflect pediatric physiology or development in relation to physical activity. Children are not mini-adults; their physiological responses differ significantly due to growth and development stages. They are also not less susceptible to cold injury compared to adults; rather, children can be more vulnerable to hypothermia and frostbite because of their lower body mass and surface area-to-volume ratios. Additionally, children's heat tolerance is not equivalent to that of adults; they often struggle more with thermoregulation during
