Abstract
Protection and safety of civilian population and property are under the responsability of some institutional roles. One of those is the Fire and Rescue Service whose role has been having over the last decades an increase and a diversification in its intervention field. In the same time their official statistics shows increase in job injuries and pathologies, especially those of the muscle scheletal and cardio-vascular system. The aim of this paper is to analyze the fitness levels of 23 firemen in a specific simulated intervention, considered by literature as their highest endurance demand. This specific test was done by climbing a stairway, wearing their protective clothes and carrying a 30 Kg extra load. The elaborated variables were: age, high, weight, %body fat, heart rate reserve (%Hrr) and the VO2max. A mathematic model (by a non linear regression) was applied on every performancedata. Moreover, applying the Principal Component Analysis, 4 components were lightened: PC1, influenced by therelative task load; PC2, related to weight and %body fat; PC3 that establish the physiologic age; PC4, related to the subject's training level. A very interesting result was the possibility, by PCA, to calculate the influence of the 4 latent factors in each partecipant' fit levels. This study could be useful to define a personalized protocol for training.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
