The project ?Recovery, Age and Performance? (R-Age) tested age-related effects of different designs of work-breaks with regard to performance and physical and psychological well-being. This thesis examines how diverse designs and patterns of breaks influence emotional strain and individual well-being of workers, with special focus on aging workers. Subjective data, as well as psycho-physiological data, was collected. 112 participants were recruited, aged 20-30 and 50-60 and coming from a wide range of computer-related professions. For this thesis, 92 participants were drawn from the pool. The examination is based on a four-factorial plan, the variables being age (young v. old), break activity (stretching v. progressive muscle relaxation v. brain jogging), break pattern (short break v. long break) and point of measurement (measurement 2, 3, 4), the points of measurement consisting of several intervals. In the examination, we recorded skin conductance (SCL), amplitude (SAmpl.) and the number of non specific skin conductance reactions (NS.SCRfreq), to show possible physiological reactions. Meanwhile, the individual well-being was recorded using questionnaires (BSKE-24ak). Significant variations were recorded for SCL and SAmpl. related to the age of the participants. For SCL, a significant interaction between repose measurement, break design and break pattern, was recorded. For NS.SCRfreq, a significant interaction between repose measurement, interval and break pattern was recorded. |
