This study examined changes in muscle temperature, electrically evoked muscle contractile properties, and voluntary power before and after a soccer specific active warm-up and subsequent rest period. Ten amateur soccer players performed two experimental sessions that involved performance of a modified FIFA 11+ soccer specific warm-up, followed by a 12.5-min rest period where participants were r...

Approximately 70 km of new decimeter-resolution seismic reflection profile data from Owasco Lake, New York define a middle Holocene (∼4600 14C yr B.P.) erosion surface in the north end of the lake at water depths as great as 26 m. Beneath the lake, postglacial sediments are up to 9 m thick and represent about 10% of the total sediment fill. Early to middle Holocene sediments, ∼6 m thick, contai...

Previous research concerned with the significance of animals in early human evolution has overwhelmingly focussed on large mammals – especially iconic suite herbivores and carnivores once inhabiting Eurasian Mammoth steppes. Building earlier work author, this paper addresses underrated importance owls for life throughout Pleistocene predatory birds which only occasionally feature Palaeolithic v...

A multi-proxy analyses was applied on the sediment core from Gulf of Saros (GoS) to identify and characterize climate hydrological changes during middle-to-late Holocene. The formation two discrete Holocene sapropel layers in GoS sediments documented for first time based total organic carbon analysis. According our paleo-proxy records, lower deposited under warm humid conditions that gave rise ...

Along most Mediterranean coasts, the endemic seagrass species Posidonia oceanica builds extensive meadows and complex peat-like bioconstruction known as ‘mattes’. These belowground deposits are recognized a valuable long-term archive allowing reconstruction study of palaeo-climatic palaeo-ecological changes in coastal environment over Holocene period. One P. matte cores sampled during coring su...

The effect of the paleoclimatic and paleoenvironmental changes on the structure of the bioticcommunities are stronger and better recorded in the shelf area than in the open sea. The present study isdevoted to impact of climatic events on some species of calcareous nannofossils. For this reason, 17samples of surface sediments of the Persian Gulf were studied. Preservation of calcareous nannofoss...

PURPOSE This systematic review was conducted to identify the impact of upper body warm-up on performance and injury prevention outcomes. METHODS Web of Science, MEDLINE, SPORTDiscus, PsycINFO and Cochrane databases were searched using terms related to upper extremity warm-up. Inclusion criteria were English language randomised controlled trials from peer-reviewed journals in which investigati...

Juniperus excelsa is the main tree species of forest stands in the upper elevations of the Kalamoun mountains in Syria. In this preliminary experiment seeds of juniper from four stands in different elevations (1900, 2100, 2200, 2250 m) were subjected to two pre-treatments with different duration period: warm stratification for three-months followed by 45 days warm stratification followed by 45 ...

Optical and radiocarbon dating indicates that alluvium underlying dunes near Abilene was deposited at or before 45 ka, and that the overlying dunes were active at 1.1–0.5 ka. Geochemical data indicate that the Abilene dune sand is immature and was derived from the underlying Pleistocene alluvium, and not from Holocene age Smoky Hill River deposits. These findings suggest that dune activation wa...

Sediments from Qipisarqo Lake provide a continuous Holocene paleoenvironmental record from southern Greenland. Following deglaciation and glacio-isostatic emergence of the basin from the sea ∼9100 cal yr B.P., proxies of lake paleoproductivity, including biogenic silica and organic matter, increased markedly until 6000 cal yr B.P. and thereafter remained stable over the ensuing warm three mille...
