TL;DR: The WAI is associated with individual characteristics, lifestyle, demands at work, and physical condition and should be taken into account in health promotion programmes aimed at maintaining and promoting the participation of the labour force and improvement of the performance at work.
Abstract: This paper systematically reviews the scientific literature on the effects of individual and work-related factors on the Work Ability Index (WAI). Studies on work ability published from 1985 to 2006 were identified through a structured search in PubMed, and Web of Science. Studies were included if the WAI was used as measure of work ability and if quantitative information was presented on determinants of work ability. In total, 20 studies were included with 14 cross-sectional studies and six longitudinal studies. Factors associated with poor work ability, as defined by WAI, were lack of leisure-time vigorous physical activity, poor musculoskeletal capacity, older age, obesity, high mental work demands, lack of autonomy, poor physical work environment, and high physical work load. The WAI is associated with individual characteristics, lifestyle, demands at work, and physical condition. This multifactorial nature of work ability should be taken into account in health promotion programmes aimed at maintaining and promoting the participation of the labour force and improvement of the performance at work.
TL;DR: Deterioration in work ability was explained by a model which included a decrease in recognition and esteem at work, decrease in workroom conditions, increase in standing at work and decrease in vigorous leisure-time physical exercise.
Abstract: Objectives This study was designed to explain changes in work ability through occupational and life-style factors. Methods Work ability was measured by an index describing workers' health resources in regard to their work demands. The work factors mainly included physical and mental demands, social organization and the physical work environment. The life-style factors covered smoking, alcohol consumption, and leisure-time physical exercise. The first questionnaire study was done in 1981 and it was repeated in 1992. The subjects (N = 818) were workers in the 44- to 51-year-old age group in the beginning of the study who were active during the entire follow-up. The improvement and, correspondingly, the decline in work ability were analyzed by logistic regression models. Results Both the improvement and the decline in work ability were associated more strongly with changes in work and life-style during the follow-up than with their initial variation. The model for improved work ability included improvement of the supervisor's attitude, decreased repetitive movements at work, and increased amount of vigorous leisure-time physical exercise. Deterioration in work ability was explained by a model which included a decrease in recognition and esteem at work, decrease in workroom conditions, increase in standing at work, and decrease in vigorous leisure-time physical exercise. Conclusions Social relations at work can promote or impair the work ability of elderly workers. Although the work ability of elderly workers generally declined with aging, both older and younger workers were also able to improve their work ability.
TL;DR: The main results of several studies carried out on Italian workers using the work ability index as a complementary tool for workers' periodical health surveillance show sex and working hours appear to act concurrently in influencing work ability, particularly in association with more physically demanding jobs.
Abstract: The current paper reports the main results of several studies carried out on Italian workers using the work ability index as a complementary tool for workers' periodical health surveillance. The work ability index shows a general decreasing trend over the years, but it changes differently according to working conditions and personal health status. In jobs with higher mental involvement and autonomy, but lower physical constraint, it remains quite constant and high over the years, while it significantly decreases with a steeper trend the higher the physical work load and the lower the job control are. Sex and working hours appear to act concurrently in influencing work ability, particularly in association with more physically demanding jobs. It is therefore necessary to adopt flexible interventions, able to give ageing shift workers a proper support for maintaining a satisfactory work ability, by means of actions addressed both to work organization and psycho-physical conditions.
TL;DR: It is concluded that a shift from 'no-diversity thinking' to 'd diversity thinking' is needed in the context of deciding about the work ability of ageing workers in high-demand jobs.
TL;DR: A function to track the dynamic state of the W' during intermittent exercise is developed, which may have important implications for the planning and real-time monitoring of athletic performance.
Abstract: PurposeThe critical power (CP) model includes two constants: the CP and the W′ [P = (W′ / t) + CP]. The W′ is the finite work capacity available above CP. Power output above CP results in depletion of the W′ complete depletion of the W′ results in exhaustion. Monitoring the W′ may be valuabl
