RT Journal Article T1 Firefighters cardiorespiratory fitness parameters after 24 weeks of functional training with and without personal protective equipment A1 Lajoso Silva, Nuno A1 Bezerra, Pedro A1 Da Silva Gomes, Bruno Tiago A1 Cancela Carral, José María K1 2411.03 Fisiología Cardiovascular K1 2411.06 Fisiología del Ejercicio K1 2411.17 Fisiología de la Respiración AB Introduction. Firefighters’ (FFs) cardiorespiratory fitness is considered an important capacity for workability. To successfullycomplete safety standards and rescue protocols, FFs are required to accomplish minimum values of relative VO2max. Physicalfitness programs for FFs must take into consideration physiological demands, being essential not only for professional tasks butalso as a guarantee of their personal safety. This research aimed to investigate the influence of specific functional training (FT)with and without personal protective equipment (PPE) and self-contained breathing apparatus (SCBA) on the FFs’ cardiorespiratory fitness. Material and methods. Sixty FFs were randomly allocated in three groups (EG1 training with PPE+SCBA; EG2training with regular fitness equipment and the control group) and enrolled for a 24-week (two sessions/week) FT interventionprogram. FFs were assessed in anthropometric and 12-minute Cooper test, pre and post-intervention. Results. Both traininggroups demonstrated significant improvements from baseline to post intervention EG1 VO2max (39.8 ± 6.5ml.kg-1.min-1 and 41.2± 5.6ml.kg-1.min-1, p < 0.001, +3.5%; EG2 VO2max 41.5 ± 8.3ml.kg-1.min-1 and 42.5 ± 7.5ml.kg-1.min-1, p < 0.05, +2.4%). Conclusions. The proposed FT intervention, considering the provided equipment in all fire departments, and even without runningtasks, seems to be adequate for developing FFs’ VO2max. Regular FT with PPE+SCAB must be encouraged to improve adequateVO2max and fitness levels related to firefighting specific tasks.
