Marci Ryan ’06, an Exercise Chemistry and Biology major, studied whether the birth control pill affects how women’s bodies use fat and carbohydrates when they exercise.

“It’s thought to be better for your body to burn more fat than calories,” Ryan says.

She tested the metabolism of 14 volunteers (seven of whom use birth control) while they were exercising at different times during their menstrual cycle. Ryan’s results showed that during exercise, the test subjects who took the pill used slightly more fat than those not on the pill.

“It’s an outstanding project,” says Biology Professor Bill Long. “It incorporates science and uses science the way it should be practiced at a high level. She identified a question, formulated a hypothesis, made predictions based on the hypothesis, tested them, analyzed data appropriately and drew conclusions. “

After she graduates, Ryan plans to pursue an advanced degree in physical therapy.
