The Role Of Adherence In Mediating The Relationship Between Depression And Health Outcomes, Rena R. Wing, Suzanne Phelan, Deborah Tate

Kinesiology and Public Health

Depression has been linked to poor health outcome in a number of studies; however, the mechanism underlying this relationship has received little attention. This paper explores the possibility that adherence mediates the relationship between depression and outcome. Principal findings regarding the relationship between depression, adherence, and outcome are reviewed. The data suggest that depression is related, at least moderately, to poorer adherence to a variety of treatment components. The relationship between adherence and outcome is more difficult to establish. In addition, current data, albeit limited, do not support the hypothesis that adherence mediates the relationship between depression and outcome. An …

Combining Behavioral And Pharmacological Treatments For Obesity, Suzanne Phelan, Thomas A. Wadden

Kinesiology and Public Health

Weight-loss medications are currently recommended for use only as an adjunct to diet, exercise, and behavior modification. Little, however, is known about the benefits of combining behavioral and pharmacological therapies or about the mechanisms that would make these combined approaches more effective than either used alone. This article reviews the effects of adding pharmacotherapy (i.e., principally sibutramine and orlistat) to a modest program of lifestyle modification. Studies revealed that the addition of medication typically improved short- and long-term weight loss compared with lifestyle modification alone. The best results, however, were obtained when medications were combined with an intensive, group program …

A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full

All HMC Faculty Publications and Research

The individual muscles of a multiple muscle group at a given joint are often assumed to function synergistically to share the load during locomotion. We examined two leg extensors of a running cockroach to test the hypothesis that leg muscles within an anatomical muscle group necessarily manage (i.e. produce, store, transmit or absorb) energy similarly during running. Using electromyographic and video motion-analysis techniques, we determined that muscles 177c and 179 are both active during the first half of the stance period during muscle shortening. Using the in vivo strain and stimulation patterns determined during running, we measured muscle power output. …
