RESUMO

Evidence regarding a putative physical fitness decline remains less well documented for Italian children and adolescents. An update review of data collection articles was undertaken concerning motor performances (power, strength, speed-agility and indirect cardiorespiratory fitness) of children and adolescents worldwide and compared with 2859 11-12-year-old Italian students of both sexes, throughout a ten-year observational period. Lower limb explosive strength (standing broad jump), flexibility (sit-and-reach), endurance (Cooper) and speed (SP-30) performances of sixth grade Italian students showed nearly stable trends, with no differences during the observed decade, in both sexes. This 10-year perspective study confirmed that Italian physical fitness levels flatlined rather than actually declined. According to these study data, the decline in physical fitness of the Italian youth is ostensible and needs a further in-depth analysis.

RESUMO

BACKGROUND: The cardiorespiratory fitness (CRF) is one of the most important indicators of the health-related physical fitness components because it reflects the efficiency of the cardiovascular and respiratory systems. To indirectly assess CRF, the original protocol of the 20mSRT was adapted in a new version suitable for children called 20mSRT-PREFIT, providing performances comparable to the standards of the European area. In fact, CRF normative values are missing in the Italian context and therefore they would be meaningful to be assessed. We aimed to determine CRF from 20mSRT-PREFIT in a small sample of Italian pre-school children and to compare the outcomes with the available European references. METHODS: A convenience sample of 5-year-old pre-school children (N.=32, M/F ratio: 19/13) was freely recruited from a kindergarten of the northwest Italy. Children performed the 20mSRT-PREFIT and the number of full shuttles, exhaustion time, and maximum speed were collected to obtain CRF. RESULTS: Predicted VO2max was similar between Italian male and female groups. All other outcomes originating from the 20mSRT-PREFIT were consistent with those included in the available European databases. CONCLUSIONS: According to these preliminary indications, Italian pre-school children may have a CRF level equivalent to that one ascertained in other European countries. Thus, current rakings should be cautiously scrutinized, as they might inappropriately underrate Italian children's performances.
