Older women suffering from clinical frailty stand to benefit from the first potential medical treatment for the condition, according to a study presented today by Penn Medicine researchers at ENDO, The Endocrine Society's 91st Annual Meeting.

A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a possible explanation for how that happens.
