Performance requirements of physically strenuous occupations: validating minimum standards for muscular strength and endurance.

Employment rights legislative mandates passed in the USA over the last three decades emphasize the importance of validating performance standards for physically strenuous occupations. This study validated minimally acceptable standards for the muscular strength and endurance necessary to perform fire suppression activities. Incumbent firefighters (n=153) selected for key demographic characteristics completed a simulated set of firefighting tasks (Fire Suppression Evolution) and then a Predictor Test Battery of physical abilities tests. Regression analysis revealed that three predictor test items (hose drag/high rise pack carry; arm lift; arm endurance) combined to significantly predict performance time of the Fire Suppression Evolution (p < or =0.01). Firefighters (n=41) rating videotaped performance times of the Fire Suppression Evolution determined that more than one-half a standard deviation slower than the mean time established by the incumbents reflected unacceptable performance. Approximately 80% of incumbent firefighters passed the minimally acceptable performance standard. Use of the 3-predictor test battery would correctly identify 89% of successful performers and 72% of unsuccessful performers. This study demonstrates that validation of minimal physical performance standards will identify a cohort of individuals with a high probability of not being able to perform critical fire suppression activities. This finding has important implications for examining the relationship between physical performance standards and medical and economic outcomes.

Employee fitness and wellness programs in the workplace.

Worksite fitness and health promotion programs have grown exponentially in the past 15 years. To examine the impact of these programs, the literature through 1988 was reviewed. In general, fitness and wellness programs result in increased levels of fitness and a reduction in the risk factors for coronary heart disease. Recent research using control groups has found relations between reduction in health care costs, absenteeism, and turnover and implementation of comprehensive health promotion programs. Issues related to participation rates, program implementation, and evaluation are also addressed.
