Abstract

The aim of this study was to determine whether elite international junior rowers in 2007 were heavier and taller than those evaluated in 1997, and to compare this change among finalists and non-finalists, and sweep rowers and scullers. Body weight and height data obtained by a questionnaire from a total of 398 rowers (42% female, 58% male) at the Junior World Rowing Championships in Beijing, People's Republic of China, in 2007 (65.9% of all competitors), were compared with data from 603 rowers measured at the Junior World Rowing Championships in Hazewinkel, Belgium in 1997 (36.5% female, 63.5% male, representing 90% and 89% of all competitors, respectively, by gender). Male and female rowers in 2007 were significantly taller compared to those in 1997 (1.0 cm, p = 0.009 and 2.1 cm, p < 0.001, respectively; one-sample t-test). No statistically significant difference was found for body mass. The finalists and sweep rowers were taller and heavier compared to nonfinalists and scullers at both Championships respectively. The heights of elite level junior rowers increased significantly over the decade. The finalists at World Junior Rowing Championships were again taller and heavier compared to the nonfinalists.

PROMJENE VELIČINE TIJELA VRHUNSKIH VESLAČA JUNIORA – USPOREDBA VESLAČA IZ 1997. I 2007. GODINE ----- Cilj ovog istraživanja bio je utvrditi jesu li vrhunski međunarodni veslači juniori 2007. godine bili teži i viši od veslača mjerenih 1997. godine, kao i odrediti tu promjenu kod finalista u odnosu na nefinaliste te kod rimen veslača u odnosu na skul veslače. Podaci o tjelesnoj masi i visini prikupljeni upitnikom na uzorku od 398 veslača (42% djevojaka, 58% mladića) na Svjetskom juniorskom prvenstvu u veslanju održanom u Pekingu, u Narodnoj Republici Kini, 2007. godine (uzorak je činilo 65,9% od ukupnog broja natjecatelja), uspoređeni su s podacima 603 veslača mjerenih na Svjetskom juniorskom prvenstvu u veslanju, održanom 1997. godine u Hazewinkelu u Belgiji (36,5% djevojaka, 63,5% mladića, što je, gledano po spolu, činilo redom 90% i 89% natjecatelja). Natjecatelji i natjecateljice iz 2007. godine bili su značajno viši u odnosu na one iz 1997. godine (1,0 cm, p=0,009, odnosno 2,1 cm, p<0,001; t-test za jedan uzorak). Za tjelesnu masu nije utvrđena statistički značajna razlika. Finalisti i rimen veslači bili su viši i teži u odnosu na nefinaliste i skul veslače, i to na oba prvenstva. Dakle, vrhunski veslači juniori postali su, u razdoblju od jednog desetljeća, značajno viši, a finalisti Svjetskog juniorskog prvenstva u veslanju ponovo su bili viši i teži u odnosu na nefinaliste.
