The most recent cross-sectional studies on the evolution of physical abilities in youth took into account the secular trend on various aspects of motricity.

In the HG 2009 test, male showed better results (without significant differences). So did females but only in the younger groups. In conclusion, some performances are improving while others are worsening and this may be due to differences in body weight, training quality and lifestyle even in non-sporting activities.

Abstract

The most recent cross-sectional studies on the evolution of physical abilities in youth took into account the secular trend on various aspects of motricity. In 1981 a survey was carried out by CONI on a national sample of young athletes (Carbonaro 1984). The purpose of the present study was to compare the results of some of the assessments performed in 1981 with the corresponding ones executed in 2009 on subjects with the same sport curriculum. The sample included 11-14 years old subjects attending the “Centri CONI di Avviamento allo Sport” for at least two years. The 1981 sample included all the Italian regions (M:1495; F:700), while the 2009 sample included all the provinces of Emilia-Romagna and Abruzzo (M:190; F:117). Anthropometric measurements (Body mass and Height), conditional tests (Standing Long Jump, Sitting Ball Throw, Shuttle Run, Hand-Grip and Seat & Reach) and coordination tests (Balance and Hand Movement Frequency) were carried out. A three-way ANOVA (gender x age x survey year) was used to analyze the considered DVs in the different conditions. Body mass was significantly higher in 2009 vs. 1981, while no differences between the survey years were shown for the height. In 1981, the SLJ, B and S&R performance was better than in 2009 in all age classes. Oppositely, the subjects tested in 2009 performed better than their 1981 counterparts in SBT, SR and HMF. In the HG 2009 test, male showed better results (without significant differences). So did females but only in the younger groups. In conclusion, some performances are improving while others are worsening and this may be due to differences in body weight, training quality and lifestyle even in non-sporting activities.
