How does exercise impact bone density and bone mineral content in growing bone?
Strenuous exercise can increase bone density by 7% and bone mineral content by 11%.
What happens to estrogen levels and ovulation in individuals with inhibited hypothalamus function?
Estrogen levels decrease and ovulation stops.
Why is optimizing bone mass early in life important?
Early optimization helps prevent rapid bone loss later in life.
What impact does long-term moderate/intense training have on bone mineral content?
Continuous activity retains the benefits of moderate/intense training on bone mineral content.
Why is vitamin D important for bone health?
Vitamin D helps store calcium in fat, impacting bone mass.
