Study Summary
This study is a randomized, cross-over intervention study that will evaluate the effect of brief, high-impact loading exercises on biomarkers of bone metabolism in energy-restricted female runners. Volunteers will complete two 5-day experimental conditions in a randomized order separated by one menstrual cycle (approximately 3 weeks). Experimental conditions will include a dietary intervention of energy intake equal to 30 kcal/kg of fat-free mass/d using controlled diets and an exercise intervention of daily treadmill running with or without an additional 50 impact loading exercises.
Primary Outcome
Plasma N-terminal propeptide of type 1 procollagen (PINP) was collected from fasted blood samples drawn before and after each 5-day intervention. The enzyme-linked immunosorbent assays (ELISA) were performed on all samples upon study completion.
Interventions
- BEHAVIORAL Impact Load Exercises
- BEHAVIORAL No Impact Load Exercises
