Running economy (RE) is the amount of oxygen utilized (ml.kg⁻¹min⁻¹) when
running a fixed speed, and it has been demonstrated to be an important factor
determining race performance in distance runners. There is evidence that running
economy and/or maximal oxygen consumption (VO₂max) improves over the course
of a training season...
The percentage of the American population who are 65 years old or older is
rapidly increasing, especially the proportion of women. It is becoming crucial to
encourage lifestyle behaviors that will enable senior women to remain in optimal
health. Following the 1990 Dietary Guidelines' recommendations to limit fat intake
and...
The US population over the age of 65 years is growing rapidly, with elderly
women outnumbering men by 50 percent. Studies show that aging is often
accompanied by reduced energy intake, inadequate nutrition, and the loss of lean
body mass with a subsequent increase in body fat, as well as...
In this study, we explored the relationships among gender, age, daily stressors, positive and negative affect, and neuroticism on cortisol outcomes in older men and women. We were particularly interested in whether variation in positive affect would have an effect on variation in negative affect and if this relationship would...
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...
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...
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...
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;...
