The purpose of this study was to consider the effect of eight weeks aerobic

and strength training on serum PTH, calcium, albumin and alkaline

phosphatase in postmenopausal women.35 post menopause women, (55-70

years), of Jahandidegan center of Tehran were selected and randomly divided

to three groups as aerobic (n=12), strength (n=13) and control (n=10) groups.

Aerobic training program include jogging and aerobic movements, with 60-

70% MHR intensity(8 weeks, 3 times per week, 40minute per session), And

Strength training program with emphasize on main muscle groups (8 weeks, 3

times per week, 1 hour per session),with30-40%1RM,8-10rep,1set to 60-

80%1RM,8-10rep,1set . One way analysis of variance (ANOVA) used to

compare differences between groups. The results showed that PTH and

alkaline phosphatase significantly increase after aerobic and strength training

in comparison with control group (P≤0.05). But the significant difference was

not observed between these two groups. No significant difference was

observed in serum calcium between two trained and control groups (p≥0.05).

However a significant decrease was observed in strength group (P≤0.05).

Furthermore, the significant change was not observed in albomin after training

program. Increase in PTH and alkaline phosphatase concentrations in normal

range seem to promote anabolism procedure of bone formation. The result of

this study shows that both two type of training have same effects on bone

markers and hormonal factors.
