Background : The ability of managers of small-scale enterprises (SSEs) to prioritize health, working conditions, and their own physical fitness is an important issue for workplace health promotion in Norway and Sweden, where most owner-manager positions are in SSEs. Aim : To assess the physical fitness status of SSE managers compared to a norm population and to study changes in physical fitness status, self-reported physical activity, and sickness outcomes after workplace health interventions. Methods : The study allocated SSE managers to either an intervention or a reference group. The intervention, over twelve months, consisted of motivational input related to lifestyle and physical activity through tests and feedback, individual support, and courses on health and psychosocial working conditions. The participants (N = 28) completed health screening checks, questionnaires and testing before and after the intervention. Results : SSE managers in the study had positive outcomes for BMI levels and strength compared to the norm population, while percentage of fat for both men and women indicated poor results. There were no further improvements in the intervention group after comparison with the reference group. Separately, both groups seemed to improve strength and body composition. Conclusion : Workplace health interventions with essentially motivational components may increase SSE managers’ attention to physical fitness, but appear to have limited effects on objective and subjective physical fitness outcomes.
