Final answer:
NTX is a bone turnover marker that is contingent upon bone health in relation to the female athlete triad.
Step-by-step explanation:
NTX, or N-Telopeptides of Type I Collagen, is a bone turnover marker that is often used to assess bone health and the risk of osteoporosis in individuals.
The female athlete triad is a condition that involves three components: disordered eating, amenorrhea (lack of menstrual periods), and osteoporosis or low bone density. NTX may be contingent upon bone health and can be used as a marker to monitor the effect of the female athlete triad on bone turnover and overall bone health.
