Because sedentary living creates health consequences that ultimately affect employees' productivity, many companies are sponsoring worksite physical fitness programs for their employees. The cost-effectiveness of such programs and the resulting reduction in employees' absenteeism rates and medical and health care costs have been well documented. In addition, many states either already have or are in the process of passing legislation offering incentives for employer-sponsored physical fitness programs. Companies desiring to develop their own worksite physical fitness programs need to recognize the need for screening procedures to determine employees' coronary risk factors and exercise tolerance levels. Staff selection, adequate liability protection, and the need for program evaluation are other important issues to consider. Company-sponsored worksite physical fitness programs vary widely from the standpoint of available facilities, activities offered, target audience, participation rates, cost to employees, and incentives for participation. In the past, most worksite physical fitness programs concentrated almost exclusively on programs for top executives and on exercise and physical fitness; as the cost-effectiveness of keeping employees physically fit become better known, however, more companies are making their programs available to more of their employees and are combining exercise and with other self-help programs.
