The girl is suffering from osteopenia.
The osteopenia is a condition, in which the bone mass of the person is significantly reduced. High amount of training and less intake of fats may cause a decrease in the hormone estrogen in young girls. this decrease in the hormone may lead to the irregular periods as well as decrease in bone mass, which eventually causes osteopenia. the osteopenia is a precursor of the osteoporosis, the osteopenia later, if untreated causes a further decrease in bone mass and porous bone (osteoporosis).

Protected from the harmful effects of free radicals, often referred to as reactive oxygen species (ROS).
Hydrogen Peroxide (H2O2) is a by-product of metabolic reactions of cells that use oxygen (aerobic respiration) to produce energy from carbohydrates (food). The problem with H2O2 is that it can be toxic to cells, due to its free radical properties, as an ROS. Organisms protect themselves from this by using an enzyme called peroxidase, also known as cayalase.
