Recreational activities play important role on workers' health conditions and improve people's creativity. Steel industry is one of industries, where workers mainly face with hard working conditions. There are various techniques to help human resources increase their potentials such as providing recreational centers, athletic facilities, etc. In this paper, we study the impact of regular swimming exercises on improving the efficiency of employees in management level in a steel complex unit called Mobarakeh Steel Complex. In this company, there were about 85 middle level managers and supervisors and the proposed study selects 30 people, randomly and divides them into two equal groups. In the first stage of the study, questionnaire of vocational relation are distributed among the participants of this study and some important factors, which could improve vocational relationships are measured. Next, the experimental groups are invited to take part in some selective aerobic programs for 8 weeks and 3 sessions per week and 1 hour and 15 minutes per session, regularly. Finally, we repeat the same experiments after the aerobic programs end and compare the results with the first one. The preliminary results indicate that the routine swimming programs have increased people self confidence, creativity and working group skills.
