Background: The Wave~Ripples for Change: Obesity Prevention in High-School Soccer Players research project is a 5-Y USDA funded project focused on building healthy nutrition, physical activity and life skills for healthy weight maintenance. The intervention includes providing face-to-face sport nutrition, physical activity and life- skills lessons, assessments of body composition,...
In endurance-trained men, an acute bout of exercise is shown to suppress post-exercise appetite and alter changes in specific appetite regulating hormones. Limited research has examined these responses in endurance-trained women. PURPOSE: To investigate the effect of exercise intensity on the appetite regulating hormones acylated ghrelin, PYY and GLP-1 and...
Metabolic syndrome (MetS) and abdominal obesity (AbOb) increase the risk of
developing cardiovascular disease and diabetes. Energy restriction (ER), highprotein
(PRO) intake and high-intensity interval training (HIT) can independently
improve MetS and AbOb. However, ER reduces metabolically active lean body
mass (LBM) in addition to body fat (BF). Purpose: To...
It has been hypothesized that caffeine intake can directly interfere with estrogen synthesis; it is also well documented that caffeine can increase energy expenditure. Active women with ExMD are at risk for the female athlete triad, a syndrome associated with negative energy balance, leading to menstrual dysfunction and eventually poor...
Research shows that Exercise-Associated Menstrual Dysfunction (ExMD) ranges
from 6-79% of active women, depending on the sport. The primary contributor to ExMD
is hypothesized to be low energy availability or relative energy deficiency in sport, due to
insufficient energy intake to match exercise energy expenditure. Because many active
women are...
Aging, obesity and increased waist circumference (WC) increases risk for metabolic syndrome (MetS). MetS is a cluster of symptoms (elevated WC, triglycerides, blood pressure, fasting glucose, and decreased high-density lipoprotein cholesterol [HDL-C]) increasing risk for chronic disease. Low-energy dense (LED) diets, emphasizing whole food eating patterns, have not been examined...
Changes in lifestyle over the last century have resulted in a dramatic increase in the incidence of diabetes in the United States (U.S.). Mexican-Americans, the largest Hispanic/Latino subgroup in the U.S., are 1.7x’s as likely to have diabetes as non- Hispanic Whites. Culturally appropriate approaches for treating diabetes in minority...
The purpose of this study is to determine whether a 12-week nutrition and physical activity (PA) intervention program for middle-aged, pre-menopausal women at risk for Metabolic Syndrome (MetS) would reduce their risk factors. Ten overweight women (mean ± SD: age = 47 ± 3y; Body Mass Index = 31.0 ±...

The prevalence of exercise-induced menstrual dysfunction (ExMD) ranges between 6-79% in endurance-trained women and may result from a low energy availability (EA; kcal/kgFFM/d). EA is the energy remaining after planned exercise, which is available for basic physiological processes and daily living activities. One mechanism for energy conservation may be a...
Menstrual dysfunction (MD), possibly due to lower energy availability (EA), is prevalent in active women and associated with unfavorable heath consequences. PURPOSE: To determine if EA improvements in endurance-trained women, using a daily Carbohydrate-Protein supplement (CHO-PRO), will restore menstrual function and improve musculoskeletal health. METHODS: Athletes with MD (ExMD; n=8;...
