“…Physical exercise is known to enhance mood and psychological coping mechanisms [183][184][185][186], as well as cognitive functioning [187], in humans. For example, exercise has been shown to decrease anxiety [188], elevate mood and coping skills in response to stress [189], and demonstrate antidepressant and anxiolytic activity [190].…”

Brain-derived neurotrophic factor (BDNF) is a member of the structurally and functionally homologous neurotrophin family. It is the most widely distributed trophic factor in the brain, and participates in neuronal growth, maintenance, and use-dependent plasticity mechanisms such as long-term potentiation and learning. There are several lines of evidence supporting a role for BDNF in the treatment of depression. This paper reviews the neurotrophin hypothesis of antidepressant action, and examines our current understanding of activity-dependent mechanisms of BDNF expression and function in limbic regions of the brain. Our discussion starts with the original observations of monoaminergic neurotransmitter dysfunction that served as the basis for early antidepressant drug development, and outlines evidence for neurodegeneration and functional deficits existing with chronic stress and depression. We continue with evidence that enhancement in neurotrophic support and associated augmentation in synaptic plasticity and function may form the basis for antidepressant efficacy, and serve as a current and future focus in the quest for more rapid-acting and effective medication treatments. Finally, we follow the current search for the intracellular mechanisms of antidepressant interventions that may bring the monoaminergic and neurotrophic hypotheses together, and help us to more fully understand the roles of both neurotransmitter and growth factor. Principal challenges to the neurotrophin hypothesis, and inconsistencies between clinical and preclinical research results, are also pointed out, as these also guide future experiments that will refine our understanding of treatment mechanisms.

“…A critical factor in an elderly (Ͼ65 years) person's ability to function independently is mobility, the ability to move without assistance. 186,[221][222][223][224][225][226] The overall focus for exercise training should be to enhance health-related fitness components, while simultaneously assisting in the reduction of risk for various chronic diseases and improving overall quality of life. Considerable evidence exists that physical activity, both endurance and resistance-type exercise, can significantly improve these indices and provide for functional independence and overall well-being, especially in the older adult.…”

“…Opportunities to socialize and enjoy a sense of camaraderie, for instance, can be primary motivating factors to attend exercise classes (Gillett, 1988). Furthermore, exercise behavior is potentially reinforced when the participant perceives and enjoys its benefits (Emery & Blumenthal, 1990;Emery, Hauck, & Blumenthal, 1992;Gillett, 1988Gillett, , 1993Sharpe et al, 1997).This project was funded by a grant from the National Institute of Nursing Research (R29 NR02087).1 Cerontology Center, University of Utah.

Sedentary, overweight women aged 60-70 years were assigned either to a 16-week health education group (/? = 70) in which they were instructed to exercise aerobically on their own three times per week or to a 16-week exercise group (n = 76) that consisted of three supervised aerobic sessions per week. Regression analyses performed at post-test and at 3-, 6-, and 18-months follow-up revealed that exercise frequency was not explained by group membership, but often was negatively associated with placing a greater value on exercising with peers. Those who were exercising more often at 6-and 18-months followup, however, valued the perceived benefits of exercise more highly. A regular exercise program can be beneficial for sedentary older women-especially those who are overweight-because it can reduce their risks for cardiovascular disease, hypertension, diabetes, and musculoskeletal problems (U.S. Dept. of Health and Human Services [USDHHS], 1990[USDHHS], , 1996. Despite the known importance of and preponderance of media attention to exercise, more than 60% of women over age 60 participate in little or no sustained physical activity of at least moderate intensity (Caspersen & Merritt, 1992). When they do initially engage in exercise, adherence often drops dramatically after 6 months (Dishman, 1994;. This has prompted investigators to examine the factors associated with adherence to exercise programs. At the intrapersonal level, some investigations have revealed that those individuals with a greater sense of mastery or self-efficacy and those who are motivated by enjoyment or satisfaction are more likely to maintain regular exercise programs (Avers & Wharton, 1991;Clark, 1996;Lyons & Lachman, 1996;McAuley, Lox, & Duncan, 1993;Oman & McAuley, 1993). Opportunities to socialize and enjoy a sense of camaraderie, for instance, can be primary motivating factors to attend exercise classes (Gillett, 1988). Furthermore, exercise behavior is potentially reinforced when the participant perceives and enjoys its benefits (Emery & Blumenthal, 1990;Emery, Hauck, & Blumenthal, 1992;Gillett, 1988Gillett, , 1993Sharpe et al., 1997).This project was funded by a grant from the National Institute of Nursing Research (R29 NR02087).1 Cerontology Center, University of Utah.

E-mail: mike.caserta@nurs.utah.edu J College of Nursing, University of Utah, Salt Lake City.Older women are often introduced to regular exercise through programs such as community or hospital-based health education classes, where an exercise regimen is prescribed, or through supervised exercise programs, such as aerobic dance or walking clubs (Gillett, White, & Caserta, 1996;Gillett et al., 1993;King, Haskell, Taylor, Kreamer, & DeBusk, 1991). Program features that promote participation include group activities where socialization, support, and a sense of group cohesion and identity are developed, and a sense of comfort is generated from ...
