Itaconic Acid Numerous well-controlled longitudinal studies have produced consistent positive effects of calcium supplementation on BMD in adolescent females (13, 14, 15), which suggests that our UK reference values are sub-optimal.Female athletes are a different sub-class all together with regard to calcium needs. Up to 400mg of calcium has been shown to be lost (in males) via sweat alone, from a 2-hr training session (17), and although Ca losses in females are unlikely to be that high, any female athlete such as marathoners or triathletes training twice a day... could be at risk of not getting enough calcium in the diet to achieve a positive Ca balance.Dr Michael Colgan, renowned New Zealand research scientist believes athletes (both male and female, and especially females with amenorrhoea) need to supplement between 1000-2000mg Ca daily.Supplementation needs should always be assessed in relation to what is actually being obtained from the diet. Dietary intake should therefore always be assessed,organic acid.along with identifying factors that could potentially increase calcium excretion - e.g. high sodium and phosphorous diets, high protein diets, and an overall high "acidic" load. Knowledge should also be sought as to the types of calcium available and their rates of absorption.A major focus in recent years within nutrition and sport for women has been with respect to the "female athlete triad". Components of the triad are disordered eating,organic salt.amenorrhoea (absence of periods), and osteopenia (as opposed to osteoporosis).A review paper on BMD data in athletes found osteopenia (as defined as BMD scores between 1 and 2.5 SD below the mean of young adults) to be significantly prevalent in those at risk of the female athlete triad. Interestingly, osteoporosis (BMD above 2.5 SD below the mean) was relatively uncommon, even in this selected "athletic" population (16).inorganic salt.This by no means relegates the problem as any less significant. A diagnosed case of osteopenia in a young female athlete may actually be a worse scenario in terms of long-term bone health, when compared to a diagnosed osteoporotic in her 60's. An athlete with osteopenia is at greater risk of developing osteoporosis than is an athlete who has normal bone mass.
