Physical outcome in a successful Italian serie a soccer team over three consecutive seasons
No full textThe aim of this study was to examine the physical performance of a successful Italian Serie A team of more than 3 consecutive seasons. Twenty-five players participated in the study and were classified into 3 playing positions: defenders (n = 9), midfielders (n = 11), and forwards (n = 5). Activities match were studied by an analysis of multiple match camera SICS throughout the competition Italian Serie A matches played at home (n = 90) for 3 consecutive seasons (first: 2004/2005; second: 2005/2006; and third: 2006/2007). Total team ball possession and time-motion characteristics were examined. Results showed that total ball possession (52.1-54.9%) and the number of points accumulated at home (40/48) improved in the past 3 seasons, whereas the final rankings at home were stable. The total distances covered by minutes of play were significantly different between the 3 seasons (118.32 +/- 6.69 m[middle dot]min-1 to 111.96 +/- 8.05 m[middle dot]min-1). Distance running and high-intensity activities were similar in the 3 seasons, whereas the distance covered in moderate-intensity running decreased in the third (p \u3c 0.05). Variations between playing positions were found during the 3 consecutive seasons, with midfielders covering greater distances than defenders (p \u3c 0.05) and forwards (p \u3c 0.01). This study showed how for 3 consecutive seasons a Serie A team of successful players reduced their distances performed at submaximal speeds, and increased ball possession, while maintaining the high-intensity activities and the number of points at home. It is suggested that this is because of a better understanding of roles and tactics team organization and to act collectively and individually on these parameters to reduce energy expenditure during the game to maintain a high-level performance throughout the season

No full textSpecies adoption for sustainable forestry in Hong Kong\u27s degraded countryside
No full textIntensively urbanized Hong Kong has a degraded countryside envelope with 170 years of afforestation history. This study assessed seedling quantity, species composition, native-exotic relativity, and native ecological traits in 30 years. Data were analysed by cluster analysis, two-way indicator species analysis (TWINSPAN), and principal component analysis (PCA). The plantations received 16.54 million seedlings from 209 species. Seedling profile skewed towards 142 native species (67.9%) and 9.49 million exotic seedlings (57.4%). The dominant species group had three exotic species each with \u3e1 million seedlings. The abundant group of 27 species had contained 19 natives associated with main primary forest components. The 179 species in frequent and rare groups denoted changing and diverse species selection. Analysis of start and truncation times found 50% of natives with ascending trend and 33% of exotics with descending trend. Aggregate ecological value of natives increased progressively. TWINSPAN classified native species into two groups with signature characteristics. PCA revealed scattered distribution of natives by adoption trend, start time, truncation time, and ecological value. Ecological restoration of synergistic-mutualistic associations between native plants and wildlife has gained importance. Potential pioneer and enrichment-planting arboreal species were identified to sustain the afforestation programme. Hong Kong has a rich vascular flora with about 390 native tree species, implying that around 250 native tree species had never been used in afforestation. Large-scale planting trials should be conducted to further refine species choice in future afforestation. The findings could inform afforestation and conservation efforts in Hong Kong and other degraded tropical lands
Prediction of resilient modulus of compacted saprolitic soils by CBR approach for road pavement subgrade: a re-examination
No full textThe scope of the study as presented in this paper is to re-examine the prediction of resilient modulus (M R) by the classical California Bearing Ratio (CBR) approach, specifically for compacted saprolitic subgrade soils. Through the extensive experiments carried out for this research, a more precise model yielded to estimate M R based on CBR values and the relative degrees of soil compaction. Likewise, comments are also made critically for the suitability of using the well-known models which were developed during the past decades. In addition to the core results, this study has produced a number of other important findings: (1) the influence of soil compaction densities on CBR and M R is relatively significant when soil is relatively dry, whereas saturation ratio becomes a dominant factor while the soil is in wetter condition; (2) when the saturation ratio becomes dominant, the soil material could rarely reach a CBR of 5% or above, which was often regarded as competent materials by many design standards; (3) the moisture ratio (R m) of the saprolitic subgrade materials is one of the useful parameters in estimating M R and (4) the distinctive behaviours of saprolitic subgrade soils under CBR, unconfined compressive strength and repeated load tests are considered to be related to the degree of freedom of volume change for soil samples during the tests
