The large-volume and relatively low-intensity training changes towards the end of pre-competitive period (somewhere of 3-6 weeks), to small-volume and highintensity training. Such training rearangementis named "tapering". The hypothetically backgroung of the "tapering" consisted of assumption that such training changes resulted also in changes of the realtionship between adaptation (Pt) and fatigue (Ut), which occures during training periods. The reduction of predominantly fatigue results in enhancement of pertformance (Yt). We have tested this hypothesis by the calculation of Yt as difference: Pt - Ut. We have shown that succesfulland quick dissapearance of fatigue during "tapering" influenced faster increase of Yt which can be reached earlier and could be prolonged for a certain period of time. Sports praxis knows "tapering" during pre-competitive period where training rearangements lasting for about 3-6 weeks. The second period, where "tapering" is used sucessfully is a microcycle during competition season. This is a week time interval, which frequently influences also peak performance of the runnerVadba v tekih na srednje proge se v predtekmovalnem obdobju dramatično spremeni. Prevladujoča velika vadbena količina in razmeroma nizka intenzivnost se z "zoževanjem" spremenita v visoko intenzivnost in nizko količino vadbe. Ta vadbeni ukrep se običajno zgodi v enem mezociklu. Njegova hipotetična podlaga temelji na predvidevanju, da se v tem obdobju spremeni razmerje med prilagojenostjo na vadbo in utrujenostjo. To hipotezo smo teoretično preverili na dveh primerih, v katerih smo izračunali zmogljivost tekača v izbranih trenutkih (Zt) kot razliko med prilagojenostjo (Pt) in utrujenostjo (Ut). Ugotovili smo, da je učinkovito zmanjševanje utrujenosti tista podlaga, ki dejansko omogoča zgodnejše doseganje visoke zmogljivosti tekača. Takšna zmogljivost se lahko ohranja tudi dlje časa. V športni praksi to lahko izkoristimo z že omenjenim "zoževanjem" v predtekmovalnih obdobjih. Lahko pa "zoževanje" uporabljamo v mikrociklih tekmovalnih obdobij. Vsakokrat lahko "zoževanje" povzroči tudi športno formo, vendar zakonitosti njunega pojava še ne poznamoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za šport
