Firefighters have to be strong enough to carry out their job in hot and smoke-filled environments, but the average age of Japanese firefighters is about forty, and is increasing.This study was undertaken in order to investigate the trainability of Japanese firefighters. They took medical checks, fitness tests and examinations of cumulative fatigue symptoms every year, and they did physical training programs. The training programs involved burpee, sit-ups, floor push-ups, half-squats and step programs (10-15 mins) for about one hour once or twice a week for 3 years (from 1997 to 2000).The findings were as follows,1. Serum lipid levels in firefighters were higher than in average Japanese.2. The fitness levels were superior to average Japanese in muscular endurance.3. As for the effects of the training, the total fitness level increased 1 year after training began, and the improved level was maintained.4. As for the effects of training, the score of cumulative fatigue symptoms decreased 1 year after training began and the improvement was maintained.
