Penn State Exercising Women's Study
This study aims to assess energy status in young sedentary and exercising women as it is related to menstrual status, bone health, psychological health, sleep variables, and cardiovascular function.
There will be three to four visits to the laboratory. Procedures include questionnaires, a blood draw, providing a hair sample, cardiovascular measurements, and bone scans, as well as resting metabolic rate, cognitive, aerobic fitness, and countermovement jump testing. Participants will be asked to collect urine samples throughout one menstrual cycle, or 28 days for amenorrheic females. Exercise and physical activity will be recorded and monitored for seven days via logs and wearables. Food intake will be recorded for three days. Collegiate athletes will be tested twice; in-season and off-season.
