Abstract
In this investigation the physical fitness of 34 recruits to the UK Fire Service was assessed before and after their initial training (tests 1–2) and on three occasions (tests 3–5) during the first 18 months of their service (n=34+6=40). The initial training (test 2-test 1) resulted in an increase in maximum aerobic power (11% p<0·05), body mass (2 kg, p<0·001), lean body mass (2·02 kg, p<0·001), and in calf girth (p<0·05). But no change in waist girth, maximum anaerobic power or measures of lung function was noted. There was evidence therefore that the men became physically fitter. In the first eighteen months of their service, subjects' maximum oxygen consumption declined to pre-training levels, while body mass continued to increase with a decrease in lean body mass (p<0·001). Strength remained unaltered or tended to fall with a decrease in calf girth (p<0·05). These changes reflected a return towards pre-training physical fitness levels. It is suggested that the initial training, while ill-matched to the firemen's habitual activity, produced levels of physical fitness which may approximate more closely to the infrequent peak requirements experienced by the men during actual fire fighting. Consequently it is concluded that the physical training during service was insufficiently intense and that a more effective programme could be designed to maintain an appropriate level of physical fitness
