The ASSO Project (Adolescents and Surveillance System for Obesity prevention), financed by the Italian Ministry of Health, aims to developa surveillance system structured on adolescents lifestyles. It is a prospective study with online data collection, simultaneous descriptivedata analysis and real time report. The ASSO-Toolkit is made of questionnaires, forms and a fitness test battery. The aims of this study isto evaluate the predictive validity, the criterion validity and the reliability of ASSO-FTB, in other words to assess how well the system operatesto meet its objectives. The ASSO-FTB consists of 20mSRT (Shuttle Run Test) to estimate cardiorespiratory fitness, the handgrip strengthtest and the standing broad jump to assess musculoskeletal fitness, the 4x10mSRT to assess motor fitness and last but not least the sit uptest to estimate muscle endurance. The project is currently spreading in southern Italy, both in urban and rural territories. A comparisonhas been made between two schools to evaluate if demographic aspects affect adolescents fitness and ensure that the project itself isreliable and reproducible. Forty male adolescents (17,32 ± 1,0 yrs; 175,3 ± 6,0 cm; 72,4 ± 14,7 kg; waist circ. 86,2 ± 12,4 cm) attending anurban secondary school and forty-nine adolescents ( 15,86 ± 1,4 yrs; 169,8 ± 8,9 cm; 64,3 ± 15) attending a rural secondary school voluntarilyparticipated to the study . In a school setting, the standardized procedures were administered by the ASSO-FTB specialist in collaborationwith the (PE) teacher. All data collected were updated through the already existing website (www.assoproject.info) and codified bythe dedicated ASSO-FTB server. Participants were significantly higher in BMI compared to data published by Espana-Romeo et al in 2010.As expected, the maximal isometric strength showed no differences between urban (35,07±7,3 kg) and rural (33,7±10,8 kg) school respectively.Data that remains in line with what published by Espana-Romeo et al in 2010. The standing broad jump (178,07 ± 26,9 cm) hasevinced less distance than Espana-Romeo study (183,4 ± 32,75), p = 0,37. On the whole findings show that there is a correlation betweenbetween handgrip and the 4x10 meter shuttle run test (r=-0.7) and between handgrip and standing broad jump (r = 0.7) underlining thatthis last test is better indicative of the upper and lower body muscular strength. The only concern comes from the VO2 max results, showinga mean value of 24 ml/kg/min. It is still to determine if the 20m shuttle run test underestimates this parameter or if adolescents haveat this stage of development a reduced cardiorespiratory fitness. The trial showed that the FTB-system is reliable and reproducible. At thisstage ASSO-FTB seems to be able to meet scientific standards. More studies are necessary for the ASSO-toolkit validation. Preliminaryresults are very encouraging.
