SUMMARY FOR ARTICLE

the purpose of this study was to examine the effects of music and music-video on perceptual attentional focus rated perceived exertion affective affective valence and enjoyment and psychophysi- ological blood glucose heart rate variables in outpatients attending a diabetes exercise clinic. participants were physician-referred outpatients with type diabetes who were recruited from a supervised exercise program at a nonprot hospital in the united states. participants had been enrolled in the diabetes exercise program for at least weeks prior to the commencement of the experimen- tal trials. the inuence of environmental manipulations involving music and video on exercise-related affect is likely to be a particularly fruit- ful endeavour in terms of assessing patterns of long-term adher- ence and health-related outcomes. the benets of exercise on the management of type diabetes have been demonstrated consis- tently yet participation rates are low.from a theoretical standpoint these results illustrate the ecacy of experi- mental manipulations pertaining to components of the information- processing system ie attentional focus in inuencing affective responses during exercise and extend previous evidence concern- ing the ecacy of music and music-video interventions in the ame- lioration of negative affect during exercise to the clinical exercise domain
