JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 111 OP 120 DO 10.1136/bjsm.32.2.111 VO 32 IS 2 A1 D Scully A1 J Kremer A1 M M Meade A1 R Graham A1 K Dudgeon YR 1998 UL http://bjsm.bmj.com/content/32/2/111.abstract AB The relation between physical exercise and psychological health has increasingly come under the spotlight over recent years. While the message emanating from physiological research has extolled the general advantages of exercise in terms of physical health, the equivalent psychological literature has revealed a more complex relation. The paper outlines the research evidence, focusing on the relation between physical exercise and depression, anxiety, stress responsivity, mood state, self esteem, premenstrual syndrome, and body image. Consideration is also given to the phenomena of exercise addiction and withdrawal, and implications for exercise prescription are discussed.
