Does periodization work? Athletes perform better in major events than in minor competitions
Previous studies on periodization have led to the view that most athletes fail to peak at major events. These conclusions might be based on definitions of “peak performance” that are too narrow. In this study, a track and field athlete was defined as succeeding in a competition if their outcome was within the acceptable range from the best result of the season. The data are from seven championship finals and semifinals together with 42 Diamond League competitions from the 2010s, altogether 7,087 individual results. All field events and running events up to 400 m were included. The majority of athletes succeeded in major events (67.0% in sprint and 57.5% in field events). Overall, champions…

Kuulantyönnön lajianalyysi ja valmennuksen ohjelmointi: erityisesti miesten kuulantyöntö
Johdanto. Kuulantyönnön tarkoituksena on työntää miehillä 7,26 kg tai naisilla 4 kg painava kuula mahdollisimman pitkälle pienestä rajatusta ringistä. Vakiintuneita työntötapoja on kaksi: perinteinen työntötapa eli pakitustyyli ja pyörähtämistyyli. Maailman kärkityöntäjissä on kummankin tyylin käyttäjiä. Kuulan saa työnnettyä pitkälle parhaiten tuottamalla maksimaalinen määrä nopeutta välineeseen. Välineeseen saadaan nopeutta muuntamalla suuri määrän maksimivoimaa räjähtäväksi voimaksi. Aikaa tuottaa voima välineeseen on karkeasti noin sekunti. Kuulantyönnön biomekaniikka. Kuulantyöntötulokseen vaikuttaa neljä tekijää: kuulan lähtökorkeus, kuulan lähtökulma, kuulan lähtönopeus ja kuulan saa…
Individuality of responses to bilateral and unilateral volume equated hypertrophic strength training in physically active men
Purpose. The purpose of the present study was to investigate possible differences between unilateral and bilateral strength training during ten weeks progressive hypertrophic strength training and six weeks detraining period. Furthermore, it was examined possible different individual responders in muscle hypertrophy during strength training and, how those different responders would behave during the detraining phase following the training period. Methods. The present intervention included ten weeks of progressive hypertrophic resistance training followed by six weeks of detraining in healthy young men (n=24). Ultrasound was used to measure vastus lateralis (VL) muscle cross-sectional area (…
