| ABSTRACT |
| Parathyroid
hormone (PTH) is the major hormone regulating calcium metabolism and
is involved in both catabolic and anabolic actions on bone. Intermittent
PTH exposure can stimulate bone formation and bone mass when PTH has
been injected. In contrast, continuous infusion of PTH stimulates
bone resorption. PTH concentration may be affected by physical exercise
and our review was designed to investigate this relationship. The
variation in PTH concentration appears to be influenced by both exercise
duration and intensity. There probably exists a stimulation threshold
of exercise to alter PTH. PTH regulation is also influenced by the
initial bone mineral content, age, gender, training state, and other
hormonal and metabolic factors (catecholamines, lactic acid and calcium
concentrations).
KEY
WORDS: Parathyroid hormone, physical exercise, calcium, catabolic/anabolic
effects.
