Short-term bouts of exercise increase serum phosphorus
concentrations at either low or high exercise intensity in
young males, which could result in an increase in serum
parathyroid hormone [82]. Phosphorus status has been
studied in adolescents athletes involved in different
types of sports [95]. Although higher BMD was observed
in the impact load sports, no differences were found in
males involved in impact load sports (i.e., gymnastics),
420
compared with loading sports (i.e., pool sports), and controls
[95].
Phosphorus intake has been shown to predict BMC at
the age of 8 years [96]. In the same study, the interaction
between phosphorus and physical activity was suggested
but not tested [96]. New studies examining the combined
effect of phosphorus and exercise on bone mass during
growth are needed
