Tiedätkö TODELLA, miten kunto kohenee? Hyviä uutisia: 20 minuuttia liikuntaa viikossa riittää - jos tavoitteesi on vain elää pidempään. Jos taas haluat kunnon kasvavan, silloinkin 20 minuutin treeni tepsii paremmin kuin parin tunnin lönkyttely. Tosin ne 20 HIIT-minuuttia ovatkin sitten silkkaa tuskaa. Kuntoilu 2.0 kumoaa liikuntaan liittyviä myyttejä yleistajuisesti ja vetävällä otteella. Tiesitkö, että venyttely ennen treeniä alentaa suorituksen tehoa? Tai että jäähdyttely on hyödytöntä, eikä hierontakaan edistä lihasten palautumista. Unohda myös tankkaus ja kalliit urheilujuomat - kaakao ajaa saman asian. Gretchen Reynolds avaa uusimman urheilututkimuksen kaikkien liikuntaa harrastavien ulottuville. Kirja herättää taatusti keskustelua, mutta se toimii myös käsikirjana. Vinkkien ja ohjeiden avulla pystyt soveltamaan käytäntöön liikuntatutkimusten tuloksia - onpa tavoitteesi sitten rikkoa ennätyksesi maratonilla tai vain reippailla pururadalla.

Responding to current debates on the place of play in schools, the authors have extensively revised their groundbreaking book. They explain how and why play is a critical part of children’s development, as well as the central role adults have to promote it. This classic textbook and popular practitioner resource offers systematic descriptions and analyses of the different roles a teacher adopts to support play, including those of stage manager, mediator, player, scribe, assessor, communicator, and planner. This new edition has been expanded to include significant developments in the broadening landscape of early learning and care, such as assessment, diversity and culture, intentional teaching, inquiry, and the construction of knowledge. New for the Second Edition of The Play’s the Thing! Additional theories on the relationship of teachers and children’s play (e.g., Vygotsky and the role of imaginary play and Reggio Emilia’s image of the competent child). Current issues from media content, consumer culture, and environmental concerns. Standards and testing in preschool and kindergarten. Bridging the cultural gap between home and school. Using digital technology to make children’s play visible. Recent brain development research. And much more!
