Tidsramme |
|---|---|---|
|
Daily Calcium intake
Tidsramme: pre and post 8 month intervention
|
Calcium intake is a potential confounding variable.
Participants were encouraged to increase their calcium intakes if found to be low before the intervention began.
|
pre and post 8 month intervention
|
|
Menstrual History
Tidsramme: pre and post 8 month intervention
|
This information was used to monitor menstrual characteristics to ensure they were still premenopausal at the post test.
|
pre and post 8 month intervention
|
|
Dietary intake
Tidsramme: At baseline at the same time as other outcomes, about 2 weeks before the beginning of the yoga training
|
Three day dietary logs were recorded by participants before the exercise intervention.
They were analyzed for caloric intake and nutrient composition using the Diet Analysis Plus 9 software.

Change in physical activity levels
Tidsramme: pre and post 8 month intervention
|
Physical activity levels estimated by the bone-specific physical activity (PA) questionnaire to monitor their PA outside of the intervention
